Answer:
- 0.67 (Absolute value = 0.67)
Explanation:
% Change in demand for imports:
= (200,000 ÷ 150,000) - 1
= 1.3333 - 1
= 0.3333
= 33%
% Change in price of imports:
= [(1/200) ÷ (1/100)] - 1
= (100 ÷ 200) - 1
= 0.5 - 1
= - 0.5
= - 50%
Elasticity of imports:
= % Change in demand for imports ÷ % Change in price of imports (exchange rate)
= 33% ÷ (- 50%)
= - 0.67 (Absolute value = 0.67)
Answer:
Side opposite the river = 120 ft
Other sides = 240 ft
Explanation:
Let 'R' denote the length of fence opposite to the river and 'L' denote the length of the other two sides.
The cost as a function of R is:
The value of R for which the derivate of the cost function is zero is the length that minimizes cost:
If R is 120 ft, then the value of L is:
The dimensions that will minimize costs are:
Side opposite the river = 120 ft
Other sides = 240 ft
Answer:
The per-share value of Marston’s preferred stock should be $92
Explanation:
The computation of the per-share value of Marston’s preferred stock is shown below:
= (Annual Dividend rate) ÷ (yields generation) × 100
= (5.75%) ÷ (6.25%) × 100
= $92
We simply divide the Annual Dividend rate by the yields generation or we can say it is a required rate of return.
All other information which is given in the question is not relevant. Hence, ignored it
Answer:
Explanation:
The coach of a college men’s soccer team records the resting heart rates of the 27 team members. You should not trust a confidence interval for the mean resting heart rate of all male students at this college based on these data because;
(a) with only 27 observations, the margin of error will be large.
(b) heart rates may not have a Normal distribution.
(c) the members of the soccer team can’t be considered a random sample of all students.
you'll have 59.2% profit margin (148,000)
