Question

Ecologists have long known that there is a relationship between the amount of precipitation a location receives and the number of trees that grow in the area. Suppose that the relationship between yearly rainfall R (x, measured in mm) and the amount of the ground covered by trees T (y, measured on a scale from 0 to 100) is represented by the linear model T=24.70 + 0.0211R, what is the amount of the ground covered by trees that receives 1230 mm of rainfall per year?

Answer 1

$T=24.7+0.0211R$

For $R=1230mm$

$T=24.7+0.0211(1230)$

$=50.653$

The amount of the ground covered by trees that receives 1230 mm of rainfall per year is approximately 50.653.
