Question

The number of insects in a jungle doubles every 10 years. If there were 1 million insects in the year 2000, choose the line plot that correctly represents the insect population in the years 2010 and 2020.

• A. Plot 1
• B. Plot 2
• C. Plot 3
• D. Plot 4

Answer 1

The correct option is B Plot 2

The insect population in the jungle doubles every 10 years.

$\text{Insect population in the year 2000}$ $=\text{1 million}$

$\text{Insect population in the year 2010}=\text{(1 million)}\times 2=\text{2 million}$

$\text{Insect population in the year 2020}=\text{(2 million)}\times 2=\text{4 million}$

Tabulating the data, we get:

Year	Insect population (in millions)
2000	1
2010	2
2020	4

Plotting this data on a line plot, we get:


Hence, the line plot that correctly represents the insect population over the years is plot 2.
