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.

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

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.

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 form of utility that refers to the enhancement of a commodity's usefulness by moving it from a place where it has little utility to another area where its utility is higher is called "place utility." For example, a bottle of water may have low utility in a store shelf where there is an abundance of water, but it would have a higher utility in a desert where water is scarce. By moving the water bottle from the store shelf to the desert, the place utility of the water bottle is increased. On the other hand, marginal utility refers to the additional satisfaction or benefit that a person derives from consuming an extra unit of a good or service, while form utility refers to the value added to a commodity by transforming it into a more useful form, such as processing raw materials into finished products. Total utility, on the other hand, refers to the overall level of satisfaction or benefit that a person derives from consuming a particular quantity of a good or service.

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.

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.

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 coefficient of the price elasticity of supply is positive. This means that as the price of a good or service increases, the quantity of it that is supplied will increase as well. Conversely, if the price decreases, the quantity supplied will decrease. The degree to which the quantity supplied responds to changes in price is what the coefficient of the price elasticity of supply measures. A perfectly elastic supply has an elasticity of infinity, meaning that even a small change in price will result in a large change in the quantity supplied. On the other hand, a perfectly inelastic supply has an elasticity of zero, meaning that the quantity supplied does not change in response to price changes.

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 correct answer is a mixed economy. A mixed economy is an economic system that combines elements of both the public (government) and private sectors. In a mixed economy, the government and private businesses work together to create economic growth and promote social welfare. In a mixed economy, the government is responsible for providing essential services such as healthcare, education, and infrastructure. The private sector, on the other hand, is responsible for creating goods and services that meet the demands of the market. This type of economy allows for the benefits of both capitalism (private enterprise) and socialism (public enterprise) to coexist. It allows the government to regulate and control certain aspects of the economy, while still allowing the private sector to operate and innovate freely. Many modern economies around the world are considered mixed economies, including the United States, Canada, and the United Kingdom.

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 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.

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.
