Answer:
A. The CV is a relative measure of risk/return.
Step-by-step explanation:
The coefficient of variation of any investment, is used to measure and calculate the total risk of that investment with respect to its per unit expected return rate.
We can also define the coefficient of variation as a ratio of standard deviation to the expected value of an investment.
The answer is - A. The CV is a relative measure of risk/return.

Answer:
$18.71
Step-by-step explanation:
18.75 = P x .05 x .75
18.75 = P x .0375
18.75 - .0375 = P
$18.71 = P
Answer:
P(A) = 44.44%
P(B) = 50%
P(B|A) = 37.5%
P(B|A) different from P(B).
A and B are independent.
Step-by-step explanation:
If we have a total of 180 students, and 80 of them have a Playstation, we have that P(A) = 80/180 = 0.4444 = 44.44%
If we have 90 students that have a Xbox, we have that P(B) = 90/180 = 0.5 = 50%
If we have 30 students that have both consoles, we have that P(A and B) = 30/180 = 0.1667 = 16.67%
To find P(B|A), we will find for a student that has an Xbox inside the group of students that has a Playstation, that is, we have 30 students in a total of 80 students, so P(B|A) = 30/80 = 0.375 = 37.5%
P(B|A) is different from P(B), the first is 37.5% and the second is 50%, so events A and B are independent events.
