Answer:
11.23%
Explanation:
Arithmetic return = Total return/Total time period
6% = (14% + 17% - 1% + x%) / 4
(6%*4) =30% + x
24% = 30% + x
x = (24% - 30%)
x = -6%
<em>For the standard deviation, we need to use </em><u><em>stdev.s function</em></u><em> in Ms Excel</em>
Standard deviation = stdev.s (14%,17%,-1%,-6%)
Standard deviation = 0.112249722
Standard deviation = 11.23%
So, the standard deviation of the stock's returns for the four-year period is 11.23%.

Answer:
(g) Between 0 and -S7.5k because residents can substitute to other products
Explanation:
Data given in the question
Increase in price of typical soda = 10 cents
Total consumed = 150,000 sodas [er day
Dropped quantity = 75,000 sodas
So by considering the above information, the per day compensating variation of the tax varies from 0 and - 7,500
Since the sugar sweetened sodas is treated as a normal goods. Moreover, people can substitute the other goods also if there is an increase in a price of the good
The -7,500 is come from = (-75,000 × 0.10)
The options are as follows
(a) Greater than -$15k because soda is a luxury good with income (b) -$15k because that is the old consumption level times the value of the tax (c) Between -S7.5k and -$15k because soda is a luxury good elasticity > 1 with income elasticity >1 (d) Between -$7.5k arti -$15k because residents can substitute to other products (e) -$7.5k because that is the new consumption level times the value of the tax ()-$7.5k because that is the change in consumption times the value of the tax (g) Between 0 and -S7.5k because residents can substitute to other products (h) Between 0 and -$7.5k because because beverages are typically necessity goods with 6) Nothing because there was no effect on income G) It is impossible to say without knowing consumers' marginal rate of substitution income elasticity less than 1
Answer:
Options B and C are correct.
- Marginal profit is negative.
- Profit is positive.
Explanation:
At q = 150
R = 80q = 80(150) = 12,000
C = 0.002(150)3 + 22(150) + 750 = 6750 + 3300 + 750 = 10,800
R > C so first is incorrect.
MR = 80
MC = 0.006(150 x 150) + 22 = 135 + 22 = 157
MC > MR so B is correct.
Profit = TR - TC = 80(150) - 0.002(150)3 - 22(150) - 750 = 12000 - 10800 = 1200
Profit is positive.
Marginal profit = MR - MC = 80 - 157 = - 77
MR is Negative
Answer:
The correct answers are: Normative; Positive.
Explanation:
The positive economy is based on specifying and demonstrating what is happening in the economy, responds to economic issues from reason and with an objective point by which things happen, focuses on determining everything that could affect it and the results that will be obtained by final.
No advice is given to remedy economic problems, rather, it describes the problems that affect the economy without mentioning whether the results will be positive or negative.
