Carlie, samantha, lily, and maria ran the 400-meter relay today at the track meet. if their times were 12.8 seconds, 13.25 seconds, 12.06 seconds, and 13.12 seconds, what was their total time for the race (in seconds)?
a. 40.13 seconds
b. 39.71 seconds
c. 51.13 seconds
d. 51.23 seconds

  D.  51.23 seconds

Step-by-step explanation:

The total time is the sum of individual times:

  12.8 +13.25 +12.06 +13.12 = 51.23 . . . seconds

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%
