The linearized regression equation for an exponential data set is log ŷ = 0.14x + 0.4, where x is the number of years and y is the population. What is the predicted population when x = 15?
A.3
B.126
C.316
D.9537

Here we know that the linearized regression equation for an exponential data set is:

Where:

The predicted population when is found by substituting this value into the equation and finding :

Since population is a natural number, we must round off, therefore, the predicted population is 316, option C.

3: 2

step-by-step explanation:

shorter piece is 2: 3, so just reverse it, and you get 3: 2

a precentage of 6th graders. the population is all 6th graders. let me know if i'm wrong, i hope this ! : )
