Question

Paisley randomly surveys 48 teachers about the type of car they drive.

Histogram where the x axis represents SUV, sedan, and truck. The y- axis runs from zero to thirty at intervals of five. The histogram for SUV is at the point fifteen on the y- axis. The histogram for sedan is at the point twenty six on the y- axis. The histogram for truck is at the point seven on the y- axis.


If Paisely randomly surveys another 300 teachers, how many would she expect to drive an SUV?

Answer 1

Answer: 94

Step-by-step explanation: Given:

Total number of teachers in the survey = 48

Number of teachers who drive SUV = 15

Number of teachers who drive Sedan = 26

Number of teachers who drive truck = 7

To find: how many of 300 teachers drive an SUV

Solution:

Ratio of teachers who drive SUV =

Out of 300, number of teachers who drive SUV =

Answer 2

94 teachers drive SUV

Explanation:

Given:

Total number of teachers in the survey = 48

Number of teachers who drive SUV = 15

Number of teachers who drive Sedan = 26

Number of teachers who drive truck = 7

To find: how many of 300 teachers drive an SUV

Solution:

Ratio of teachers who drive SUV =
`(15)/(48)=(5)/(16)`

Out of 300, number of teachers who drive SUV =
`(5)/(16)(300)=93.75`
`\approx 94`
