45, 40, 36, 38, 42, 48, 40, 40, 70, 45, 42, 43, 48, 36 can some one me find
the mean in this and also the median?

Mean:43.8

Median: 42

Step-by-step explanation:

Mean:

To get the mean we must add all of the terms, and then divide by the number of terms.  There are 14 numbers so I will divide the sum by 14.

Add:

45+ 40+36+38+ 42+ 48+ 40+ 40+ 70+ 45+ 42+ 43+ 48+ 36 = 613

Divide:

613/14 = 43.78

Median:

To get the median we must arrange them in order like :

36,36,38,40,40,40,42,42,43,45,45,48,48,70

And then find which number is in the middle.  I will do so by crossing out numbers from the front and back.

36,38,40,40,40,42,42,43,45,45,48,48

38,40,40,40,42,42,43,45,45,48

40,40,40,42,42,43,45,45

40,40,42,42,43,45

40,42,42,43

42,42

We are left with 42 and 42, and the average of 42 and 42 is 42.  The the answer is 42.

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%
