When elasticity is zero, the demand curve is_____________

Détails de la réponse

When the elasticity of demand is zero, the demand curve is said to be perfectly inelastic. This means that a change in price will not cause any change in the quantity demanded. In other words, no matter how much the price changes, the quantity demanded will remain the same. For example, if the price of insulin for diabetes treatment were to double, people who depend on it to survive would have no choice but to continue buying the same amount. This is because they cannot reduce their consumption of insulin, and therefore, the demand for insulin is perfectly inelastic. In terms of the demand curve, a perfectly inelastic demand curve is vertical, meaning that it is a straight line perpendicular to the horizontal axis. This is because, as mentioned earlier, the quantity demanded remains constant regardless of the price. So, when graphed, the demand curve will be a straight vertical line.

The two major types of international trade are Bilateral trade and?

Détails de la réponse

The two major types of international trade are bilateral trade and multilateral trade. Bilateral trade refers to the exchange of goods and services between two countries. It involves the negotiation and agreement of terms and conditions between two parties, and it usually results in a trade surplus or deficit for each country. On the other hand, multilateral trade involves the exchange of goods and services among three or more countries. This type of trade is governed by international trade agreements, such as the World Trade Organization, and aims to promote free trade and economic cooperation among member countries. In summary, bilateral trade involves trade between two countries, while multilateral trade involves trade among three or more countries and is governed by international trade agreements.

The number of people who are qualified to work and who offer themselves for employment is called____________?

Détails de la réponse

The term used to describe the number of people who are qualified to work and who offer themselves for employment is called the "Working Population". The working population refers to individuals who are of working age and are either employed or actively seeking employment. This group of people is considered to be the supply of labor in the economy and is an important factor in determining the overall health and stability of the labor market. It's important to note that the working population can be influenced by various factors such as migration, education levels, and the availability of job opportunities. Understanding the size and composition of the working population can provide valuable insights into the current state of the labor market and can inform decisions related to economic and labor policies.

The type of business finance that entitles the holder to a fixed rate of dividend is______________--

Détails de la réponse

The type of business finance that entitles the holder to a fixed rate of dividend is called "preferred stock." Preferred stock is a type of investment in a company that gives shareholders a higher priority claim on dividends compared to common stockholders. This means that if the company distributes profits as dividends, the holders of preferred stock will receive their dividend payments first, before common stockholders. In addition to priority dividend payments, preferred stockholders may also have other advantages over common stockholders, such as the ability to vote on certain matters, and a greater degree of safety in the event of bankruptcy or liquidation. The key feature of preferred stock is that it provides a fixed rate of dividend, which is agreed upon at the time of issuance. This means that the company is obligated to pay a certain amount of dividend to preferred stockholders, regardless of how the company performs financially. This can make preferred stock a relatively stable investment option, especially for investors who are seeking a regular income stream.

The basic economic problems of society include___________

Détails de la réponse

The basic economic problems of society refer to the fundamental challenges that arise from the limited availability of resources and the unlimited wants and needs of individuals and society as a whole. The three main economic problems are scarcity, choice, and opportunity cost. Scarcity refers to the limited availability of resources, such as land, labor, and capital, relative to the unlimited wants and needs of individuals and society. This means that choices must be made about what to produce, how to produce it, and for whom it should be produced. The second economic problem is choice. Because resources are scarce, individuals and societies must make choices about what goods and services to produce and consume. This requires answering questions like "what to produce," "how much to produce," "how to produce it," and "for whom to produce it." These choices have important consequences for the allocation of resources and the distribution of income and wealth. The third economic problem is opportunity cost. This refers to the cost of choosing one option over another, as measured by the value of the best alternative foregone. In other words, every time we make a choice, we give up the opportunity to do something else with those resources. This means that the cost of any choice is not only the direct cost of producing or consuming a good, but also the opportunity cost of not using those resources in some other way. In summary, the basic economic problems of society include scarcity, choice, and opportunity cost. These problems arise from the limited availability of resources relative to the unlimited wants and needs of individuals and society, and require making choices about what to produce, how to produce it, and for whom it should be produced.

The use of income and expenditure instruments or policies to control or regulate the economic activities of a country is known as?

Détails de la réponse

The use of income and expenditure instruments or policies to control or regulate the economic activities of a country is known as Fiscal Policy. Fiscal policy involves the use of government spending and taxation to influence the economy's performance. For example, during a recession, the government may increase its spending to stimulate economic growth and create jobs. Alternatively, during a period of high inflation, the government may reduce its spending and increase taxes to reduce the amount of money in circulation and lower inflation. Fiscal policy can be used to achieve various economic objectives, such as stabilizing the economy, promoting economic growth, and reducing income inequality. It is an essential tool for governments to manage the economy and ensure its stability and growth over the long term.

The ultimate objectives of economics is to_________?

Détails de la réponse

The ultimate objective of economics is to make the best use of scarce resources. This means that economics seeks to understand how people, businesses, and societies allocate limited resources such as land, labor, capital, and technology in order to satisfy unlimited wants and needs. The goal is to ensure that resources are used in the most efficient and effective way possible, so that people can enjoy a higher standard of living and greater economic prosperity.

If the standard deviation of a given data is 8.2, find its variance_______________

Détails de la réponse

The variance of a given data is the square of the standard deviation. Therefore, if the standard deviation of a given data is 8.2, the variance can be calculated as follows: Variance = Standard deviation^2 Variance = 8.2^2 Variance = 67.24 So, the variance of a given data with a standard deviation of 8.2 is 67.24.

The mean is the best measure of central tendency because it__________

Détails de la réponse

The mean is considered the best measure of central tendency because it is a balancing point in an observation. Central tendency refers to the tendency of data to cluster around a particular value in a distribution. The three measures of central tendency are mean, median, and mode. The mean is the arithmetic average of a set of data and is calculated by summing all of the values and dividing by the number of values in the set. The mean is the balancing point in an observation because it takes into account all the values in a set of data and calculates their average. It is the sum of all the values in the set divided by the total number of values. Because the mean is based on all the values in the data set, it is less likely to be affected by extreme values (outliers) than other measures of central tendency, such as the median or mode. In addition to being a balancing point in an observation, the mean has several other advantages as a measure of central tendency. For example, it is easy to calculate and is a useful tool for comparing different data sets. It can also be calculated from incomplete data, which is not the case with other measures of central tendency. Overall, the mean is the best measure of central tendency because it is a balancing point in an observation and takes into account all the values in a data set, making it less likely to be influenced by extreme values.

Which of the following is an invisible item?

Détails de la réponse

The invisible item in the list is "Banking services". In economics, visible items are tangible goods that can be physically seen and touched, while invisible items are intangible services that cannot be physically seen or touched. Petroleum services, processed rice, and processed milk are all visible items because they are tangible goods that can be seen, touched, and measured. On the other hand, banking services are intangible and cannot be physically seen or touched. Examples of banking services include providing loans, managing savings accounts, facilitating transactions, and offering financial advice. Therefore, banking services are considered an invisible item because they are intangible and cannot be physically seen or touched.

In the long run, all production factors are____________

Détails de la réponse

In the long run, all production factors are variable. This means that in the long run, a firm can adjust all of its inputs, including labor, capital, and resources, to produce the level of output it desires. Unlike the short run, where some production factors are fixed and cannot be changed, the long run allows firms to make changes to all of their inputs, such as investing in new technology or equipment, hiring or firing employees, and even moving to a new location. For example, in the short run, a bakery may only be able to increase its production by hiring more workers or working longer hours, as its oven and baking equipment are fixed. But in the long run, the bakery could invest in new, larger equipment to increase its production capacity, as well as relocate to a larger facility or even open new stores. Therefore, in the long run, all production factors can be adjusted, making them variable, while in the short run, some factors are fixed, making them less adaptable to changes in production levels.

Want may be defined as insatiable desire or need by human beings to own goods or services that give satisfaction. Human wants or needs are many, and are usually described as insatiable because the means of satisfying them are limited or scarce

If a demand curve that intersects a perfectly inelastic supply curve shift is rightward, then____________

Détails de la réponse

The money paid per hour for work done is_________

Détails de la réponse

The money paid per hour for work done is called a "wage rate". Wage rate is the amount of money an employee is paid for each hour of work. It's a basic unit of pay that reflects the compensation an employee receives for the time and effort they put into their job. The wage rate can be influenced by various factors, including the employee's experience, qualifications, and the type of work they do. It's important to note that wage rate is different from salary, which is a fixed amount of money paid to an employee for a set period of time, usually annually or monthly. A bonus, on the other hand, is an additional payment made to an employee in recognition of good work or as a reward for achieving a specific goal.

Calculate the population density of Nigeria, having a total population of 180 million with a total land area of 923,768 sq km?

Détails de la réponse

To calculate the population density of Nigeria, we need to divide the total population of Nigeria by its total land area. So, Population density of Nigeria = Total population of Nigeria / Total land area of Nigeria Plugging in the values, we get: Population density of Nigeria = 180,000,000 / 923,768 sq km Solving this equation, we get: Population density of Nigeria = 195 people per sq km (rounded to the nearest whole number) Therefore, is the correct answer. Nigeria has a population density of approximately 195 people per square kilometer, which means that on average, there are 195 people living in every square kilometer of land in Nigeria. This number is relatively high compared to some other countries, but it is important to note that population density varies widely depending on factors such as geography, climate, and economic development.

The reward for capital is___________

Détails de la réponse

The reward for capital is interest. Capital refers to the money or assets that are used to invest in a business or enterprise. When someone invests their capital into a business, they expect to earn a return on their investment. The return on investment for capital is called interest. Interest is the amount of money paid by the borrower to the lender for the use of their capital. This can be in the form of regular interest payments or a lump sum at the end of the investment period. The interest rate is determined by various factors such as market conditions, inflation, and risk. Therefore, interest is the primary reward for capital.

Occupational distribution of information is mainly influenced by___________

Détails de la réponse

Occupational distribution of population refers to the classification of the working population into different types of work they engage in. The occupational distribution in any population is influenced by factors which includes: The level of education, Availability of natural resources, The level of technology, The type of production activities.

The diagram below represents a production function. At which of the points does diminishing returns set in __________

Détails de la réponse

Diminishing returns set in at point T in the production function. In a production function, adding more units of input (such as labor or capital) typically leads to an increase in output at a certain rate. However, as the amount of input increases beyond a certain point, the rate of output increase begins to decline. This is known as the law of diminishing returns. In the diagram, points R and S represent the increasing phase of the production function where output increases at an increasing rate as more input is added. However, at point T, the rate of increase in output begins to slow down, indicating that the law of diminishing returns has set in. Beyond point T, adding more input will result in smaller increases in output, and may even cause a decrease in output if the input becomes too excessive, as shown by point V. Therefore, point T is where diminishing returns set in, indicating the optimal level of input for maximum output.

The formation of cartels or monopolies in other to obtain better bargaining or deals from other countries is characteristic of which of the following?

Détails de la réponse

The formation of cartels or monopolies in order to obtain better bargaining or deals from other countries is characteristic of countries producing the same or identical goods. When multiple countries produce the same or very similar goods, they may face competition from each other in the global marketplace. This competition can lead to lower prices and lower profits for all the countries involved. To avoid this, these countries may form a cartel or monopoly by agreeing to work together to limit production or fix prices. By doing so, they can increase their bargaining power and negotiate better deals with other countries or buyers. For example, the Organization of the Petroleum Exporting Countries (OPEC) is a cartel made up of oil-producing countries that work together to regulate the supply and price of oil in the global market. By working together, they can maintain higher prices for their oil and negotiate better deals with buyers. Overall, the formation of cartels or monopolies can be a way for countries producing similar goods to gain more control over the market and secure better economic outcomes for themselves.

The population density of a town made up of 50 square kilometer land area and 100 million people is________

Détails de la réponse

To calculate the population density, we need to divide the total population by the land area. Population density = Total population / Land area In this case, the total population is 100 million and the land area is 50 square kilometers. So, Population density = 100 million / 50 square kilometers Simplifying the above expression, we get: Population density = 2 million people per square kilometer Therefore, the correct option is "2 million people per square kilometer".

The factor of production that has the highest degree of mobility is__________?

Détails de la réponse

The factor of production that has the highest degree of mobility is labor. Labor refers to the human effort used in the production of goods and services. It includes both physical and mental work, such as the work done by factory workers, managers, doctors, and teachers. Unlike other factors of production, such as land and capital, labor is not fixed and can move from one job or industry to another. Labor mobility is the ease with which workers can move between different jobs or locations. It is influenced by factors such as education, skills, training, and the availability of job opportunities. For example, a person with a degree in computer science can easily move from one technology company to another, and a nurse can work in a hospital or a clinic. The mobility of labor is important for the efficient functioning of the economy because it allows workers to move to industries and locations where their skills are in demand, which increases their productivity and wages. It also helps businesses to find the talent they need to grow and innovate, and it enables regions to adapt to changing economic conditions. Therefore, labor mobility is an important aspect of economic growth and development.

The policy by which government encourages producers of export goods to produce and export more in order to earn more foreign exchange is called__________

Détails de la réponse

The policy by which the government encourages producers of export goods to produce and export more in order to earn more foreign exchange is called export promotion. This policy is aimed at increasing the volume and value of a country's exports, thereby increasing its foreign exchange earnings. Export promotion can take many forms, including providing financial incentives, such as subsidies and tax breaks, to producers of export goods. It can also involve providing training and support to help exporters improve their competitiveness, as well as promoting a country's exports through trade shows and other marketing initiatives. The goal of export promotion is to help a country's businesses increase their exports, create jobs, and boost the economy.

The need to construct a scale of preference is necessitated by____________

Détails de la réponse

The need to construct a scale of preference is necessitated by scarcity and the need for choice. Resources are limited, but human wants and needs are unlimited. This creates a situation of scarcity, where people must make choices about how to allocate their resources to satisfy their most pressing needs and wants. A scale of preference is a tool that helps individuals to prioritize their wants and needs, so that they can make informed choices about how to allocate their limited resources. For example, imagine you have a limited amount of money to spend on groceries for the week. You have a long list of items you want to buy, but you can't afford to buy them all. By constructing a scale of preference, you can prioritize the items on your list according to how important they are to you. You might decide that buying bread, milk, and vegetables are your top priorities, while buying luxury items like chocolates and wine are lower on your list. This allows you to make the most of your limited resources and satisfy your most pressing needs first. Therefore, the need to construct a scale of preference is necessitated by scarcity and the need for choice, as it helps individuals to allocate their limited resources in a way that best satisfies their wants and needs.

The reward for capital is___________

Détails de la réponse

The reward for capital refers to the return or compensation that an investor receives for providing their money as an investment in a business or project. This reward can take various forms, but some common ones are interest, rent, and dividends. Interest is a reward for lending money, and it is usually expressed as a percentage of the amount borrowed. For example, if you lend $1,000 to a company that promises to pay you 5% interest, you will receive $50 in interest payments each year. Rent is another form of reward for capital, and it is often associated with real estate. If you own a property and rent it out to tenants, you receive a regular income stream in the form of rent payments. This income can be a reward for the capital you have invested in the property. Risk is also a consideration when it comes to the reward for capital. Investments with higher risks may have the potential for higher returns, but they also have a greater chance of losing money. Therefore, investors who take on greater risk may expect a higher reward for their capital. Premium refers to an additional payment made to investors above and beyond their expected return. This may be offered to incentivize investment or to reward investors who are willing to take on greater risk or tie up their capital for a longer period of time. In summary, the reward for capital can take many forms, but it generally refers to the return that investors receive for putting their money to work in a business or investment. The specific form of the reward will depend on the type of investment and the risks involved.

The bank type responsible for the formulation of rules and regulations guiding the banking industry is known as?

Détails de la réponse

The bank type responsible for the formulation of rules and regulations guiding the banking industry is the Central bank. A central bank is an independent financial institution that oversees the monetary policy and banking system of a country. Its main functions include regulating commercial banks, managing the country's money supply, and controlling inflation. The central bank is also responsible for formulating rules and regulations that guide the banking industry, as well as ensuring compliance with these rules. In many countries, the central bank is the lender of last resort, meaning that it provides emergency loans to commercial banks in times of financial crisis. Examples of central banks include the Federal Reserve in the United States, the European Central Bank in Europe, and the Bank of Japan in Japan.
