Question

There are approximately 40,000 people that live in a city. A sample of 20,000 people from that city are asked and 8,000 live in an apartment.

How many people from the entire population would you expect to live in an apartment?

Answer 1

16000

Explanation:

Answer 2

16,000 people

Explanation:

Let's write a ratio

8,000:20,000

Let's write another ratio

x:40,000

We can write a percent proportion.

`(8,000)/(20,000) =(x)/(40,000)`

We can see that the relationship between the denominators is multiplied by 2 so that means the relationship between 8,000 and x is x is 2 times greater than 8,000
