Answer:
16.7
Explanation:
Calculation for What is the variance of returns of the portfolio
First step is to calculate the mean
Mean = (20% + 25% + 30%) / 3
Mean =75% / 3
Mean = 25%
Now let calculate the variance of returns of the portfolio
Portfolio variance of returns = {(20 − 25)^2 + (25 − 25)^2 + (30 − 25)^2} / 3
Portfolio variance of returns=25+0+25/3
Portfolio variance of returns=50/3
Portfolio variance of returns= 16.7
Therefore the variance of returns of the portfolio will be 16.7
Answer:
Yes it does. Yes it does.
Answer:

Explanation:
To find the income elasticity we first must recall the formula

which is the percentage change in quantity when income increases in one percent.
From the demand curve we can find
by taking derivative of Q with respect to Y: 
Next we need to know what is the income at the equilibrium quantity of 1300, which we can back out from the data given in the question


Then

Answer:

If the marginal cost curve lies below the average cost curve then as output increases, <u>average total cost </u><u>is </u><u>decreasing. </u>
<h3>What is marginal cost?</h3>
- It shows the cost of producing an additional unit.
When this measure is decreasing, it means that every time another unit is produced, less cost is incurred. This will lead to average total cost falling because there is less cost but more output.
