X = 25.7 min
100 180.4 min
x(180.4)=25.7 (100)
180.4x=2570
180.4x/180.4=2570/180.4
x=14.25%
Answer:
6) Total number of students who took the test = 240
7) (2) 90% of the students who took the test ha scored equal or less Sal's score.
Step-by-step explanation:
<h3>6)</h3>
Formula to calculate 5th percentile
percentile = (# students who scored ≤ 60 / total number of students) * 100
5th = 12/n * 100
5/100 = 12/n
0.05 = 12/n
n = 240
Total number of students who took the test = 240
<h3>7)</h3>
90th percentile means Sal scored better than 90% of people who took the test.
I think it would be 3.75 x 10^1.
