Answer 2

`54%`

Explanation:

Given is a frequency table showing the students' scores on a recent math test.

Score Frequency

41-50 1

51-60 2

61-70 8

71-80 12

81-90 20

91-100 7

We have to find the percentage of the students scored at least 81

on the test

From the frequency table we find that 20 students gained 81 to 90 and 7 students from 91 to 100

No of studence who scored atleast 80
`= 20+7 =27`

Total frequency =
`50`

Hence percentage of the students scored at least 81

on the test=
`(27)/(50) (100) = 54%`

Answer is
`54%`
