Question

11. If you randomly selected 500 U.S. homes, about
how many would be heated with fuel oil?

Answer 1

50

Explanation:

Given

Total number of US houses = 500

If 10% were affected by fuel oil

Total number affected by fuel oil = 10% of 500

Total number affected by fuel oil = 0.1 * 500

Total number affected by fuel oil = 50

Hence 50 houses were affected by fuel oil
