The length of time required by students to complete a 1-hourexam is a random variable with a density function given by f(y) = cy2 + y, 0 = y = 1 0, elsewhere
A. Find c.
B. Find F(y)
C. Graph f(y) and F(y)
D. Use F(y) in (b) to find F(-1), F(0), and F(1)
E. Find the probability that a randomly selected studentwill finish in less than half an hour.
F. Given that a particular student needs at least 15 minutesto complete the exam, find the probability that she will require atleast 30 minutes to finish.

required rate of return = 0.166 = 16.6%

step-by-step explanation:

under the capital asset pricing model (capm), the required or expected rate of return for a particular security or asset is given using the formula:

required rate of return = risk-free rate + beta*(market risk premium)

we are given that;

risk-free rate = 4% = 0.04

beta = 1.4

market risk premium = 9% = 0.09

we simply plug these values into the above formula;

required rate of return = 0.04 + 1.4*(0.09)

required rate of return = 0.04 + 0.126

required rate of return = 0.166 = 16.6%

ok so what's the question?

step-by-step explanation:

you have to find the same variables -3n - 5n so this would be -3n +(-5n) which equals -9n
