Answer Details

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.

When a group data is involved, cumulative frequency is used. The formula will be: Median=[(N+1)/2]th

  For member of odd number items. That is, where N is odd

  Median=([N/2]th + [N/2 + 1]th)/2

  For member of odd number items. That is, where N is odd

  Solution:

  From the table, there are 20 members as indicated by the cumulative frequency. Since the members are odd (10) the median age will be ([N/2]th + [N/2 + 1]th)/2

  Median=([10/2]th + [10/2 + 1]th)/2

  =(5th + 6th)/2

  The 5th member is 3 and the 6th member is on 3

  Median=(3 + 3)/2

  =6/2

  Median = 3

A capital market differs from the money market in that in the former, the loans sought are long term, whereas in the money market, the loans sought are short term. A capital market refers to the financial market where companies and governments can raise long-term funds by issuing and selling securities such as stocks, bonds, and other financial instruments. Investors who buy these securities are essentially lending money to the issuing entity for a longer duration, with the expectation of receiving interest payments and eventual repayment of the principal amount. The securities traded in the capital market have longer maturities, typically longer than a year. On the other hand, the money market is a financial market where short-term financial instruments such as treasury bills, commercial paper, and certificates of deposit are traded. The loans in the money market are typically for a duration of less than a year, with the purpose of meeting short-term funding needs. The interest rates on these loans are generally lower than in the capital market, given their short-term nature. In summary, while both markets deal with financial instruments, the primary difference between them is the duration of the loans sought, with the capital market focusing on long-term funding needs and the money market on short-term funding needs.

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".

Answer Details

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.

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 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.

Taxes and government expenditures are instruments of fiscal policy. Fiscal policy refers to the government's use of its spending and taxation powers to influence the economy. By adjusting the level of taxes and government spending, the government can influence the level of economic activity and control inflation. For example, if the government wants to stimulate economic growth, it may lower taxes and increase government spending. This increases consumer spending and investment, which can boost economic activity. On the other hand, if the government wants to slow down inflation, it may raise taxes and decrease government spending, which can reduce consumer spending and slow down economic growth. In summary, fiscal policy is a crucial tool used by governments to manage their economies and maintain economic stability.

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.

The business organization that is allowed to raise capital by sales of shares to more than twenty people is a Public limited liability company (PLC). A Public limited liability company is a type of business organization that is owned by shareholders who own shares of the company. These shares can be bought and sold by the general public, allowing the company to raise capital by selling shares to more than twenty people. In contrast, a Private limited liability company (Ltd) is a type of business organization that is owned by a small group of shareholders who are often family members or close friends. Private limited liability companies are not allowed to sell shares to the general public and are limited to selling shares to a maximum of 20 people. Partnerships and Sole proprietorships are not allowed to issue shares at all, as they are not considered separate legal entities from their owners. Instead, they raise capital by borrowing money from banks, investors or using their own funds.

Economics seeks to study the relationship between ends and means. Ends are unlimited while the means are limited. Scarcity means resources are limited in relation to the ends. Economics therefore seek is concerned with allocating limited resources among the competing and unlimited wants.

Answer Details

The economic term used to refer to human wants, desires, or needs is "Ends". In economics, ends refer to the goals or objectives that individuals or society aims to achieve. These are the things that people want or need, such as food, shelter, clothing, entertainment, or education. Ends are considered to be unlimited because there are always new wants or needs that arise as people's tastes and preferences change, as well as advances in technology and innovation. However, the resources to satisfy these ends are limited, which creates a problem of scarcity. To achieve these ends, individuals must use alternative means, or resources, such as labor, capital, or natural resources. Therefore, the correct option is "Ends".

The study of Economics becomes necessary because of the "scarcity of resources". Economics is the study of how societies use limited resources to satisfy their unlimited wants and needs. Because resources such as land, labor, and capital are limited, and human wants and needs are unlimited, there is always scarcity. Scarcity means that people have to make choices about what goods and services they will produce and consume because they cannot have everything they want. Therefore, the study of economics helps to provide a framework for making decisions about how to allocate scarce resources in the most efficient and effective way possible to maximize benefits to society. In conclusion, the study of economics becomes necessary because of the scarcity of resources, which creates the need to make choices and allocate resources efficiently to satisfy the unlimited wants and needs of society.

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.

Total budget =$7,200

  Expenditure on Health = x/$7200 × 3600 = 600

  3600x = 600 × $7200

  x = 600×$7200/3600

  x = $1,200

  Therefore, the budget allocated to Health is $1,200

  Expenditure on Agriculture =x /$7200 × 3600 = 800

  3600x = 800 × $7200

  x = 800 × $7200/3600

  x=$1,600

  Therefore, the budget allocated to Agriculture is $1,600

  Ratio of expenditure on Health to Agriculture;

  Ratio=1200:1600

  =3:4

The privatization exercise in Nigeria is a move towards a market economy. A market economy is a type of economic system in which decisions regarding investment, production, and distribution are guided by the price signals created by the forces of supply and demand. In a market economy, resources are owned and controlled by individuals and private enterprises, rather than the government. In Nigeria's case, the privatization exercise involves the transfer of ownership and control of state-owned enterprises (SOEs) to private individuals or companies. This shift from state ownership and control to private ownership and control is a characteristic feature of a market economy. By reducing the role of the government in the economy, the privatization exercise in Nigeria is aimed at promoting competition, encouraging innovation, and improving efficiency in the management of these formerly state-owned enterprises.

Answer Details

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 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 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 expression of cost in terms of alternative forgone is referred to as "Opportunity cost". Opportunity cost is the cost of an alternative that must be forgone in order to pursue a certain action or decision. In other words, it is the value of the next best alternative that you have to give up in order to choose a certain option. For example, if you have $100 and you can either buy a new book or go to a concert, the opportunity cost of buying the book is the value you would have received from going to the concert (and vice versa). If you choose to buy the book, you give up the experience of going to the concert, and if you choose to go to the concert, you give up the value you would have received from the book. Opportunity cost is an important concept in decision making, economics, and business, because it helps us understand the trade-offs that we make when we make choices with limited resources. By considering the opportunity cost of different options, we can make more informed and rational decisions about how to allocate our resources.

The concept of division of labor is usually associated with Adam Smith, a Scottish economist who lived in the 18th century. Smith is known as the father of modern economics and his book "The Wealth of Nations" is considered a landmark in the history of economic thought. Division of labor is the process of breaking down the production of goods or services into smaller tasks, with each worker specializing in a particular task. Smith argued that this specialization allows workers to become more efficient and productive, as they become more skilled at their specific task over time. He famously used the example of a pin factory to illustrate the benefits of division of labor, showing how the productivity of the workers could be increased by breaking down the process of pin-making into smaller, specialized tasks. Smith believed that the division of labor not only increased productivity, but also led to economic growth and prosperity. By allowing each worker to focus on their specific task, and by encouraging trade and exchange between different workers and regions, the economy as a whole could become more efficient and produce more goods and services. This, in turn, would lead to greater wealth and prosperity for society as a whole. Overall, Smith's ideas about the division of labor had a profound impact on the development of modern economics and are still widely studied and discussed today.
