Jina does a weekly exercise program consisting of cardiovascular work and weight training. Each week she exercises for at least 6hours. She spends at most 11 hours doing cardiovascular work. She spends at most 4 hours of weight training. Let x denote the time(in hours) that jina spends doing cardiovascular work.

Step-by-step explanation:

I think your question is missed of key information, allow me to add in and hope it will fit the original one.  

Yolanda does a weekly exercise program consisting of cardiovascular work and weight training. Each week, she exercises for at least 6 hours. She spends at most 11 hours doing cardiovascular work. She spends at most 4 hours on weight training. Let x denote the time (in hours) that Yolanda spends doing cardiovascular work. Let denote the time (in hours) that she spends on weight training. Shade the region corresponding to all values of x and y that satisfy these requirements.

Here is my

Let x is the hours of doing cardiovascular work

Let y is the hours of doing weight training

Given that :

<=> x + y ≥ 6 (1)

<=> x ≤11 (2)

<=> y ≤ 4 (2)

x ≥0 (3)

y≥0 (4)

After that, we have the system of of inequalities (1) (2) (3) (4)

step-by-step explanation:

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%
