Question

A neighborhood has 250 families. Natalie randomly selects 20 families to survey about recycling. Of the 20 families she surveyed, 18 of them recycled. About how many families in her neighborhood recycle?

Answer 1

The total families in the neighborhood were recycled is 225

Step-by-step explanation:

Given as :

Total number of families in neighborhood =  250

The number of families random selected for survey about recycle= 20

number of families randomly recycled out of 20 = 18

Let The total families in the neighborhood were recycled = N

According to question

∵ Out of 20 families, number of families recycled = 18

So, Out of 1 family, number of families recycled = $\dfrac{18}{20}$

∴ Out of 250 family, number of families recycled = $\dfrac{18}{20}$ × 250

i.e  N = $\dfrac{18}{20}$ × 250

Or,  N = 225

So, The total families in the neighborhood were recycled = N = 225

Hence, The total families in the neighborhood were recycled is 225 Answer
