Chapter 8.4, Problem 19STP

To determine

To find:the greatest population change

Answer to Problem 19STP

The correct option is D.

Explanation of Solution

Given:

  

Calculation:

Considering the graph,

Now, the change of population between 2 decades is greatest where the rate of change of variable y (population) will be more for a constant rate of change of x (years) or in other words the slope will be greater.

The formula to calculate slope when two points $(x_1,y_1)\text{}\text{}and(x_2,y_2)\text{}$ is given is:

  $m=\frac{y_2-y_1}{x_2-x_1}$

It is observed that the change of slope is greater in the decade (2000 − 2010)

Conclusion:

Therefore, the correct option is D.
