Any help? seems easy but keep getting it wrong.

69.6 inches

Step-by-step explanation:

The mean height from a frequency table is given by

We need to multiply the frequencies by the weight and sum them up to get:

5×64+2×65+5×66+1×69+3×72+2×75+5×77=1600

The total frequency is 23.

We substitute into the formula to get:

The mean height to the nearest tenth is 69.6 inches

i think is g(1)=-1.

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%
