Question

the table and the graph show the population of a country between 2010 and 2015.
find the average rate of population growth between 2010 and 2015 in millions. do not round your answer.

Explanation:

Step1: Identify the formula for average rate of change

The formula for average rate of change is $\frac{f(b)-f(a)}{b - a}$. Here, $a = 2010$, $b=2015$, $f(a)=36.5$, $f(b)=39.1$.

Step2: Substitute the values into the formula

$\frac{39.1 - 36.5}{2015 - 2010}=\frac{2.6}{5}$

Answer:

$0.52$
