The results of the survey are shown in the table.What is the relative frequency of eight graders who want fruit smothies?A. 0.17B. 0.03C.0.02D.0.48

Answer 1

0.03

Explanation:

I got it right.

Answer 2

We need to find the relative frequency of the eighth-graders who chose the fruit smoothies.

To find a relative frequency we need to divide the number of people from eight grade who chose fruit smoothies, shown in the following image:

Divide that number by the total number of people in eighth grade:

Thus, we get the following:

`\text{relative frequency=}\frac{Number\text{ of eighth graders who want smoothies}}{\text{Total number of eighth graders}}`

Substituting our values:

`\text{relative frequency=}(17)/(250)`

Solving the division:

`\text{relative frequency =}0.068`
