An environmentalist tracks the total number of trees y in a park after x years of a planting program. The line of best fit for t
kolezko [41]

Answer:

33.33%

Step-by-step explanation:

The line of best fit for the data is represented by the equation y = 3x + 15.

At x = 4,

y = 3(4) + 15 = 27

At x = 7,

y = 3(7) + 15 = 36

We need to find the percent change in the total number of trees from x = 4 to x = 7.

So,

\%=\dfrac{36-27}{27}\times 100\\\\=33.33\%

So, the required percentage change is equal to 33.33%.
