Given information
Given:-
To find:- Estimate the rate of population growth in 1920 and in 1980 by averaging the slopes of two secant lines.
Step-by-step explanation
Step 1.
Estimate the rate of population growth in 1920 by finding the slope between 1910 and 1920, and the slope between 1920 and 1930 , and averaging them,
The slope between 1910 and 1920 is:
The slope between 1920 and 1930 is:
So, the rate of growth in 1920 is approximately ,
million people per year.
