If two commodities are unrelated, a change in the price of one will____________
Awọn alaye Idahun
If two commodities are unrelated, a change in the price of one will have no effect on the quantity demanded of the other. This is because unrelated commodities are not substitutes for each other, so a change in the price of one will not affect the demand for the other. For example, if the price of apples increases, it will not affect the demand for bananas, since apples and bananas are not substitutes for each other. Similarly, if the price of bananas decreases, it will not affect the demand for apples. This is because the demand for each commodity is determined by its own factors, such as income, tastes, and preferences, and not by the price of other unrelated commodities.

Whatever form an economic system may take, choice is essential for members of the community because resources are__________
Awọn alaye Idahun
Scarce. This means that there is not enough of a certain resource to meet the demand or needs of everyone in the community. As a result, choices have to be made about how to allocate these limited resources among different individuals, groups, or uses. When resources are scarce, it is important to make decisions about their use in the most efficient and effective way possible.

An economy system that uses what is regarded as the "Market mechanism" is called_______
Awọn alaye Idahun
Capitalism is an economic system that uses the market mechanism. In a capitalist economy, individuals and businesses own and operate the means of production, and the prices of goods and services are determined by supply and demand in the marketplace. In simple terms, this means that people are free to produce and sell whatever they want, and consumers are free to buy whatever they want, at prices that are determined by the market. This creates an economy that is driven by competition and innovation, and is often associated with growth and prosperity. It is important to note that capitalism can take on different forms, ranging from a more laissez-faire approach with minimal government intervention, to a more regulated form with a larger role for the government in managing the economy.

The arithmetic mean of 5, 8, 10, 15, 24 and 28 is_______
Awọn alaye Idahun
To find the arithmetic mean of a set of numbers, you need to add up all the numbers and divide the sum by the total number of numbers. In this case, we have six numbers, so we need to add them up and divide by 6. Adding up the numbers, we get: 5 + 8 + 10 + 15 + 24 + 28 = 90 Then, we divide the sum by the total number of numbers: 90 / 6 = 15 Therefore, the arithmetic mean of 5, 8, 10, 15, 24 and 28 is 15.

Awọn alaye Idahun
An isoquant shows equal level of output. An isoquant is a curve that represents all the possible combinations of inputs (such as labor and capital) that can produce the same level of output for a particular product or service. In other words, it represents all the different ways to produce the same amount of output using different combinations of inputs. So, all points on an isoquant represent the same level of output, and this level of output gives us the same satisfaction or usefulness. As we move along the isoquant, we can produce the same output using different combinations of inputs, but the level of output remains constant. In simple terms, an isoquant is a line that shows the different combinations of inputs that can produce the same level of output.

The method obtained by adding all the reward of factors of production in national income is________
Awọn alaye Idahun
The method of adding up all the rewards of the factors of production in national income is known as the "income approach." The income approach calculates national income by summing up all the income received by individuals and firms in the economy. This includes wages, salaries, interest, rent, and profits earned by the factors of production, such as labor, capital, and land. The idea behind this approach is that the total income generated in an economy is equal to the total amount spent on consumption and investment, and this spending creates the demand for goods and services produced in the economy. This method provides a comprehensive picture of the total income generated in the economy and is useful in understanding the distribution of income among different groups in the economy and the sources of economic growth.

The demand for labour is a________
Awọn alaye Idahun
The demand for labor is a "derived demand". This means that the demand for labor is not a direct demand for labor itself, but rather it is derived from the demand for goods and services that labor can produce. In other words, businesses hire workers because they need them to produce the goods and services that they sell. For example, if a business sells pizzas, it will need workers to make the pizzas, deliver the pizzas, and serve the customers. The demand for labor in this case is derived from the demand for pizzas. If the demand for pizzas increases, the demand for labor to produce and deliver the pizzas will also increase. Therefore, the demand for labor is closely tied to the demand for the goods and services that labor produces, and it is derived from that demand.

A rise in the supply of a commodity cause__________
Awọn alaye Idahun
When the supply of a commodity increases, it means that there is more of that commodity available in the market than before. This increase in supply causes the market to shift, leading to a change in the equilibrium price and quantity of that commodity. As the supply of the commodity increases, sellers will want to sell more of the commodity, but buyers may not want to buy as much at the higher price. This creates a surplus, where there is more supply than demand, causing the price to decrease. As the price decreases, buyers are more willing to buy the commodity, and sellers may reduce the amount they are willing to sell, until the market reaches a new equilibrium. This new equilibrium will have a lower price and a higher quantity bought and sold than before the increase in supply. Therefore, the correct answer is: a decrease in the equilibrium price and an increase in the equilibrium quantity bought and sold.

Awọn alaye Idahun
A retailer is distinguished by the nature of its sales, which is in units. Retailers sell products in small quantities directly to consumers for their personal or household use. They purchase products from wholesalers or manufacturers and sell them to the end-users at a markup. This type of retailing typically involves a physical store where customers can browse and purchase products, but it can also include online retailing. The focus of retailing is on selling individual units of products to the consumer, rather than selling in bulk to other businesses.

The term M33 comprises M11 together with deposits on deposit accounts held by banks and discount houses. In economics, M33 refers to a measure of the money supply in an economy, which includes all of the components of M11 (i.e. notes and coins in circulation, and deposits held by banks and building societies), as well as the deposits held by discount houses. Discount houses are financial institutions that specialize in providing short-term loans to other financial institutions, such as banks. Because they hold deposits from these other financial institutions, their deposits are included in measures of the money supply like M33. , banks only, and banks, discount houses, and stock exchanges, are not complete answers because they do not include the role of discount houses in M33. discount houses only, is not a complete answer because it excludes the role of banks in M33. banks and discount houses, is the correct and complete answer.

Among the disadvantages of the one-man business is the fact that______
Awọn alaye Idahun
The main disadvantage of a one-man business is that the proprietor is personally liable for the firm's debts. This means that if the business is unable to pay its debts, the proprietor's personal assets, such as their savings, property, or other valuables, can be used to settle the debt. This can put the proprietor's personal financial stability at risk and may discourage them from taking on certain business ventures or expanding the business.

Whether a monopolist is able to increase his revenue by restricting his output depends on the shape of the_________
Awọn alaye Idahun
The shape of the demand curve determines whether a monopolist is able to increase their revenue by restricting output. A monopolist is the only seller in the market and has some control over the price of the good or service they provide. If the demand for their product is high, they can increase the price, and if they restrict the quantity of the product they supply, the price will go up even more. The demand curve shows the relationship between the price of a good and the quantity of it that consumers are willing and able to buy. If the demand curve is downward sloping, it means that as the price of the good increases, the quantity demanded decreases. This is because consumers will switch to cheaper alternatives when the price of the good goes up. So, if the monopolist restricts their output, the price will go up and they will make more profit as long as the demand curve remains downward sloping. However, if the demand curve becomes perfectly inelastic, meaning that the quantity demanded does not change with the price, then the monopolist will not be able to increase their revenue by restricting output. Therefore, in simple terms, the shape of the demand curve determines whether a monopolist can increase their revenue by restricting output.

Consider the diagram below which shows a demand curve (d).
Total expenditure on a commodity is represented by the area TUVW. Consumer's surplus is represented by__________
Awọn alaye Idahun
Consumer's surplus is represented by the area above the demand curve and below the market price. In the diagram, this would be the area represented by VWX. Consumer's surplus measures the difference between the amount that consumers are willing to pay for a good and the amount they actually pay. In the diagram, consumers are willing to pay more for the good up to the market price, represented by the height of the demand curve. The area VWX represents the amount by which they are benefiting from the market, as they are paying less than they would be willing to pay. So, the answer to the question is the area VWX represents consumer's surplus.

If AC and MC are represented on a graph, the MC curve will cut the AC curve_______
Awọn alaye Idahun
The MC (marginal cost) curve will cut the AC (average cost) curve at the minimum point on the AC curve. This is because the minimum point on the AC curve represents the lowest average cost of production, and the MC curve intersecting the AC curve at this point indicates that the marginal cost of producing one more unit is equal to the average cost. In other words, at the minimum point on the AC curve, any further increase in production would lead to an increase in the average cost.

The average curve and the marginal curve are U-shaped in the short-run and flatter in the long-run due to________
Awọn alaye Idahun
The reason why the average curve and the marginal curve are U-shaped in the short-run and flatter in the long-run is due to economies of scale. Economies of scale refer to the cost advantages that firms experience as they increase their production output. In the short-run, firms are often operating at less than their optimal capacity and therefore may experience diseconomies of scale as they increase output, which leads to higher average costs and a U-shaped average curve. Meanwhile, the marginal cost curve intersects the average cost curve at its minimum point, which is why it is also U-shaped in the short-run. However, in the long-run, firms have more time to adjust their inputs and can increase the scale of their operations. As they do so, they can experience economies of scale, which lead to lower average costs and a flatter average curve. This means that the marginal cost curve intersects the average cost curve at a lower point than in the short-run, making it flatter. Overall, this illustrates how economies of scale can affect a firm's production costs and how this can be reflected in the shape of the average and marginal cost curves.

An oil spill is the release of a liquid petroleum hydrocarbon into the environment. This can occur in a variety of ways, such as from an oil tanker that leaks or a pipeline that ruptures. The oil can contaminate the water and harm wildlife, as well as damage the natural environment and disrupt human activities such as fishing and tourism. It is important to take measures to prevent and clean up oil spills to minimize their impact on the environment and local communities.

Which of the following matters may account for changes in demand?
I - changes in consumer preferences
II - changes in real income
III - changes in distribution of incomes
IV - changes in levels of taxation
Awọn alaye Idahun
Changes in demand can be influenced by various factors. Among them, changes in consumer preferences, real income, distribution of incomes, and levels of taxation can all affect the quantity of a good or service that consumers are willing and able to buy at a given price. I. Changes in consumer preferences refer to shifts in the tastes and preferences of consumers. For example, if people start to prefer healthier food options, the demand for fruits and vegetables may increase while the demand for processed foods may decrease. II. Changes in real income can also impact demand. If people's real income increases, they may be able to afford more goods and services, which can lead to an increase in demand for those products. Conversely, if real income decreases, consumers may cut back on their spending, leading to a decrease in demand. III. Changes in the distribution of incomes can also affect demand. If the distribution of incomes becomes more unequal, with some people becoming much richer and others becoming much poorer, this can impact the demand for certain products. For example, if the rich become richer, they may be more willing to purchase luxury goods, leading to an increase in demand for those products. On the other hand, if the poor become poorer, they may not be able to afford certain goods, leading to a decrease in demand. IV. Changes in levels of taxation can impact demand by affecting the disposable income of consumers. If taxes increase, consumers may have less disposable income, leading to a decrease in demand for certain goods and services. Conversely, if taxes decrease, consumers may have more disposable income, leading to an increase in demand for certain products. Therefore, the answer is: I, II, III, IV, since all four factors can account for changes in demand.

Let the quantity demanded in units of a particular commodity be represented as Qd = 80 - 2P, find the quantity demanded when P = ₦3.
Awọn alaye Idahun
The quantity demanded (Qd) of a commodity is related to its price (P) through the equation Qd = 80 - 2P. So, if we know the price of the commodity, we can use this equation to find the quantity demanded. In this case, the price is given as ₦3. So, we can plug in this value of price into the equation to find the quantity demanded: Qd = 80 - 2P Qd = 80 - 2 * 3 Qd = 80 - 6 Qd = 74 Therefore, the quantity demanded when the price is ₦3 is 74 units.

Awọn alaye Idahun
Secondary production refers to the process of transforming raw materials into finished goods, typically in a factory setting. Out of the four options, only one involves transforming raw materials into finished goods in a factory setting, and that is option II, an automobile assembly-line worker. A bricklayer (option I) works in construction and is not involved in transforming raw materials into finished goods in a factory setting. An accountant (option III) works in the service sector and is not involved in producing goods. A cinema projectionist (option IV) is also not involved in producing goods but rather in providing a service. Therefore, the answer is option II, an automobile assembly-line worker.

Awọn alaye Idahun
Most of the national debt is "dead weight" in the sense that it is not covered by any real asset. This means that the debt is not backed up by any tangible property or valuable resource. Instead, it is simply a financial obligation that the government owes to its creditors, who have loaned the government money. The government must pay back this debt with interest, which can add up over time and become a burden on the economy. This type of debt is sometimes referred to as "dead weight" because it does not contribute to the growth or development of the economy, but instead represents a financial obligation that must be met.

If wage rate is less than the average revenue product, the firms would be earning________
Awọn alaye Idahun
If the wage rate is less than the average revenue product (ARP), the firms would be earning a profit. The ARP is the amount of revenue generated by one unit of labor and is typically greater than the wage rate. If the firm is paying its workers less than the amount of revenue they generate, the firm will have extra revenue left over, which is a profit. So, in this situation, the firm would either be earning a normal profit or a super normal profit, depending on the size of the gap between the wage rate and the ARP. A normal profit is the minimum level of profit necessary for a firm to stay in business, while a super normal profit is a profit that is higher than the normal profit.

Awọn alaye Idahun
The term "Money at call and short notice" in a bank's assets represents the bank's loans to the money markets. Money at call and short notice refers to loans that the bank has made to other financial institutions or borrowers that can be quickly repaid upon request or on short notice, typically within 24 hours or less. These loans are typically used to finance short-term funding needs, such as meeting daily operational expenses or managing cash flows. The money markets are where short-term borrowing and lending takes place, typically for a period of less than a year. This includes activities such as interbank lending, commercial paper, and repurchase agreements. By providing loans to the money markets, banks are able to earn interest income while also helping to facilitate the flow of funds between borrowers and lenders. In summary, "Money at call and short notice" represents the bank's loans to the money markets, which are a key part of the financial system for short-term borrowing and lending.

Awọn alaye Idahun
A commodity is defined as normal when its demand changes in the same direction as income. This means that as income increases, demand for the commodity will also increase, and as income decreases, demand for the commodity will decrease. Normal goods are those goods for which demand increases as income increases, and decreases as income decreases. For example, as people's incomes increase, they may choose to buy more luxury items such as expensive cars, jewelry, or designer clothing, which would be considered normal goods. On the other hand, as people's incomes decrease, they may choose to cut back on these purchases and switch to more budget-friendly options, causing demand for normal goods to decrease.

Awọn alaye Idahun
Inductive reasoning is a method of analysis that draws conclusions from data rather than general principles already known. In simple terms, inductive reasoning takes specific observations or pieces of evidence and uses them to form a general conclusion or pattern. For example, if you observe that every time it rains, the streets get wet, you can use inductive reasoning to conclude that rain causes the streets to get wet. In contrast, deductive reasoning starts with a general principle or premise and uses it to reach a specific conclusion. For example, if you know that all birds have feathers and you observe a creature with feathers, you can use deductive reasoning to conclude that it's a bird. Inductive reasoning is often used in scientific research, where data is collected and analyzed to form hypotheses or theories that can then be tested through further experimentation.

Awọn alaye Idahun
If the demand for a commodity is perfectly elastic, it means that even a small change in price will cause a significant change in the quantity demanded. In other words, consumers are very sensitive to changes in price, and if the price increases, they will simply buy another substitute product that is cheaper. Now, if a tax is imposed on this commodity, it will cause the price of the commodity to increase. Since the demand is perfectly elastic, consumers will not be willing to pay the higher price and will switch to substitute products. As a result, the entire incidence of the tax falls on the seller or producer of the commodity. This is because the higher price caused by the tax will result in a decrease in the quantity demanded, and the producer will have to reduce the price in order to sell the product. Therefore, the producer bears the entire burden of the tax. In summary, if the demand for a commodity is perfectly elastic, the incidence of a tax on that commodity will be entirely on the seller or producer, as consumers are very sensitive to price changes and will switch to substitute products if the price increases.
