Last year there were 1435 8th grade students enrolled at your school. This year there are 1220. What is the percent change in the number of 8th grade students?

14.98%

Step-by-step explanation:

The formula for calculating the percentage change is given as :

% change = change / actual value x 100

change = 1435 - 1220

change = 215

original value = 1435

substituting into the formula , we have

% change = 215/1435 x 100

% change = 14.98

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%

-3.5 degrees per hour

step-by-step explanation:

find the unit rate:

-12   1/4 degrees           12.25 degrees

= - = -3.5 degrees per hour
