Answer 2

Answer:

$54%$

Step-by-step 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=$\frac{27}{50} (100) = 54%$

Answer is$54%$
