What is the percentage, to the nearest tenth, of 29-year olds with some degree of heart disease?

Question

The function P(x)= 120/1+372e^-0.133x models the percentage, P(x), of Americans who are

x years old and have some degree of heart disease.

Answer 1

P(x) = 120/(1+372e^-0.133x)

Let x = 29.

First find e^-0.133(20)

Multiply that by 372 then add 1

Divide that result into 120.
