A number is at most fifteen

x ≤ 15

Step-by-step explanation:

This is a problem about inequality.

These are the inequality symbols:

>            greater than

<            less than

≥            greater than or equal to

≤            less than or equal to

Choose a variable for the number

let "x" be the number

"x" is maximum 15. This means "x" can be 15, 142, 1, 0, -1 etc...

"x" cannot be 16, 17... any number greater than 15.

"x" is less than or equal to 15.

x ≤ 15

You might also see the answer like this:

15 ≥ x

It means the same thing because the "open" side is still facing "15". The "closed" side is still facing "x".

Although, the variable on the left side is standard formatting.

50-60=10

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%
