Answer 1

5,150,000 people

Explanation:

Let's denote the population of Indiana residents aged 5 years and older as x. We know that 453200 people were afraid of the dark, which is 8.8% of the population x. We can use this information to set up an equation:

453200 = 0.088x

To solve for x, we can divide both sides by 0.088:

x ≈ 5,150,000

Therefore, the estimated population of Indiana residents aged 5 years and older is approximately 5,150,000

Answer 2

5.15 million

Explanation:

You want the population of Indiana 5 years and older, given that 453200 people represents 8.8% of that age group.

Population

The given relationship is ...

453200 = 0.088 × population

In millions, we can write this as ...

0.453200 = 0.088 × population

Then the population in millions is ...

population = 0.4532/0.088 = 5.15

The population of Indiana 5 years and older is about 5.15 million.
