The histogram below is based on data from the American Automobile Manufacturers Association. It shows the ages of a sample of 1000 cars in a typical city in the United States.

Find the ratio of the number of cars between 3 and 6 years old to the total number of cars. (Enter your answer as a fraction.)

Answer 1

How many cars are within that 3-6yr range?

Answer 2

360

Answer 3

so that number over your total number (sample size). Do you need to further simplify the fraction?

Answer 4

and I don't think the value is 360..

Answer 5

170 + 190 = 360

Answer 6

Why are you adding the cars younger than three years?

Answer 7

so you only look at year 6

Answer 8

You want the cars greater than/equal to 3yrs old and cars less than/equal to 6yrs old - so the green bar

Answer 9

20

BETWEEN 3 and 6 years - bound is [3,6]. All the cars within those bounds.

Answer 12

190

Answer 13

There ya go, now what is your total value?

Answer 14

1000

Answer 15

So what would your ratio be?

190:1000

Answer 17

Problem wants it in fraction form

Answer 18
