Will mark brainliest! set up the following word problem as a proportion and solve. a health department estimates that 12 vials of malaria serum will treat 150 people. at this rate, how many vials are required to treat 325 people? what proportion would us to solve this? i think the answer is 26 vials that are required to treat 325 people but i'm not sure ; -;

Step-by-step explanation:

The proportion would be -

12 / 150 = x / 225.

That is, 12 per 150, x amount per 225

To solve this proportion, you can cross multiply (multiply the values diagonally)

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get

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%
