Answer:
b). 72.458 %
a). 24, 213
Explanation:
1). The second option i.e. 72.458% correctly measures the variance percentage brought in the dependent variable(regressed the quantity demanded) by manipulating the independent variable(price elasticity). The first option is wrong as it shows R multiple which is rather the coefficient. The third and the last options are incorrect as they display the intercept employed to determine the quantity and the key error of calculating the standard deviation.
2). The predicted quantity demanded would be 24,213 if the price is fixed at $7.00.
It can be calculated using the formula;
Quantity demanded = Intercept + (Adjusted R squared * Price coefficient)
∵ Quantity Demanded = 56,400.50 + (7 X -4,598.2)
= 24,213
Answer: a. 0.042 b. 0.086 c. 0.00692
Explanation:
NOTE: Convert months to years. So 24 months = 2 years.
a. Six months
Months to year conversion gives: 6months/24months as 1/4 years
= (1 + 18%)^ 1/4 — 1 x 100%
= 1.042 — 1
= 0.042
Equivalent Discount Rate = 0.042
b. One year
12months/24months as 1/2 years
= (1 + 18%)^1/2 — 1 x 100%
= 0.086
Equivalent Discount Rate = 0.086
c. 1 month
1month/24months as 1/24 years
= (1 + 18%)^1/24 — 1 x 100%
= 0.00692
Answer:
0.73 or 73%
Explanation:
Return on investment (ROI) shows the benefit an investor receives in relation to their invested amount. It is expressed as a ratio or a percentage of the net income against the investment's cost.
It is calculated using the formula below.
ROI = returns( profits)/ cost of investments.
For Lena, the cost of investment is $52,000( cost of the degree). The returns for one are the earnings in the year, which is $38,000.
ROI= $38,000/ $52,000
ROI =0.73 or 73%
It is true that because of the substitution problem, the CPI tends to overstate the true change in the price of the typical basket of consumer goods.
<h3>What is CPI?</h3>
- A consumer price index measures a market basket of goods and services that households have purchased at a weighted average price.
- The measured CPI fluctuates to reflect changes in prices over time.
- One of the most popular methods for determining inflation and deflation is the CPI.
- An essential gauge of an economy's health is inflation. The CPI and other indexes are used by governments and central banks when making economic decisions.
- The decision to raise or cut interest rates is crucial among these.
- If the CPI increases, it indicates that the average rate of change in price over time has increased. The cost of living and income are eventually changed as a result of this.

Answer: B. The investor has a short-term capital loss of $20,000.
Explanation:
A short-term loss occurs when a deficit is realized when there's a sale of an asset which has been held by the person for a period of one year or less.
In this case, since the security was worthless, it's a loss and was also help for six months which is less than one year, then it's a short term capital loss.
Therefore, the correct option is B
