Answer:
[tex]54%[/tex]
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 [tex]= 20+7 =27[/tex]
Total frequency = [tex]50[/tex]
Hence percentage of the students scored at least 81
on the test=[tex]\frac{27}{50} (100) = 54%[/tex]
Answer is[tex]54%[/tex]
