The mean tests scores with standard deviations of four English classes are given in the table. A 3-column table with 4 rows. The first column is labeled class with entries Mrs. Jones, Mrs. Rjio, Mr. Phan, Mrs. Scott. The second column is labeled mean with entries 89, 82, 73, 90. The third column is labeled standard deviation with entries 1. 9, 1. 4, 3. 4, 6. 1. Which statement is most likely to be true? The scores from Mrs. Jones’s class are the closest to the class mean. The scores from Mrs. Rijo’s class are the closest to the class mean. The scores from Mr. Phan’s class are the closest to the class mean. The scores from Mrs. Scott’s class are the closest to the class mean.

b

step-by-step explanation:

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.

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%
