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 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.

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 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 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 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.

In an open economy, GNP (Gross National Product) is measured as: C + I + G + (X - M), where: - C represents private consumption expenditures by individuals and households. - I represents gross investment by businesses, such as spending on capital goods like machinery, buildings, and equipment. - G represents government spending on goods and services. - X represents exports, which are goods and services produced domestically and sold to foreign countries. - M represents imports, which are goods and services produced in foreign countries and purchased domestically. The formula above takes into account both domestic and foreign economic activities. The net difference between exports (X) and imports (M) is included to determine the impact of international trade on the economy. Therefore, by using the formula C + I + G + (X - M) to measure GNP in an open economy, we can get a better understanding of the overall economic activity, including the impact of international trade on the economy.

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 establishment of industries in rural areas will help to reduce Urban-Rural migration. Urban-Rural migration refers to the movement of people from urban (city) areas to rural (countryside) areas in search of better living conditions, employment opportunities, and a lower cost of living. This migration often leads to overcrowding, strain on urban resources, and an increase in poverty in both urban and rural areas. When industries are established in rural areas, it creates employment opportunities for people living in those areas. This leads to an improvement in the standard of living of the local population, as they can find employment opportunities near their homes and do not need to move to urban areas. As a result, people are less likely to migrate from rural areas to urban areas in search of better opportunities, which helps to reduce Urban-Rural migration. In addition, the establishment of industries in rural areas also leads to an increase in economic activity in those areas, which stimulates local economies and creates new business opportunities. This, in turn, can lead to a reduction in poverty, an improvement in infrastructure and services, and an overall improvement in the quality of life for people living in rural areas.

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.

An ad valorem tax is imposed on the value of a commodity. This type of tax is calculated as a percentage of the value of a product, rather than a fixed amount. For example, if a product is worth $100 and the ad valorem tax rate is 10%, the tax would be $10. The word "ad valorem" is Latin for "according to value". Ad valorem taxes are commonly used on consumer goods, such as clothing or electronics, and are applied at the point of sale. The purpose of this tax is to raise revenue for the government and to potentially regulate certain products by making them more expensive.

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.

Mortgage banks give loans to investors on a long-term basis to build houses. When people want to buy a home, they may not have enough money to pay for it all at once. In this case, they can apply for a mortgage loan from a bank. A mortgage is a loan that is used to buy a property and is usually paid back over a period of several years. Mortgage banks specialize in giving out loans for the purpose of purchasing property, such as homes or other buildings. The loan is typically secured by the property being purchased, which means that if the borrower cannot repay the loan, the bank can take possession of the property to recoup its losses. Investors who want to build houses can also get mortgage loans from banks. In this case, the loan is used to finance the construction of the property, and the property serves as collateral for the loan. Overall, the primary purpose of mortgage banks is to give long-term loans to investors who want to buy or build houses. By providing this service, mortgage banks help to stimulate the housing market and make it easier for people to achieve their dreams of homeownership.

Both statements are correct. Climate and availability of water are important factors that can affect where people choose to live. Areas with a favorable climate and a reliable source of water are often more attractive to people, leading to higher population densities in those regions. On the other hand, areas with harsh climates or limited access to water may have lower population densities. Density of population refers to the number of people living in a given area. By understanding the population density in different regions, we can get a better understanding of how densely populated an area is and how the population is distributed over the land. This information is useful in a variety of fields, including urban planning, resource management, and public health.

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.

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

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.

Efficiency of labour may be defined as the ability of labour to increase output without increasing the quantity of labour. Increase in efficiency is usually expressed in terms of increase in output of labour within a shorter period of time without any fall in the quality of goods and services produced. Factors which affect efficiency of labour include Education and training, attitude to work, working conditions of workers. However, total population is not a factor that affects efficiency of workers.

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".
