Acres: 6,420,000 3,060,000 7,610,000 7,930,000 8,667,000


A. What was the average annual rate of acres burned per year from 2000 to 2016?


B. Which was greater: the average rate of acres burned from 2000 to 2008 or the average rate of acres burned from 2008 to 2016?

Answer 1

A) 6,737,400 (I think)

B) The average rate of 2008 to 2016

Explanation:

A)

(6,420,000 + 3,060,000 + 7,610,000 + 7,930,000 + 8,667,000)/5 = 6,737,400

(Here we take the whole amount burned and divide it by 5 which is the number of years presented)

B)

2000 to 2008 :

6,420,000 + 3,060,000 + 7,610,000 = 17,090,000

Whereas 2008 to 2016 :

7,610,000 + 7,930,000 + 8,667,000 = 24,207,000

Therefore the answer is :

The average rate of 2008 to 2016
