Question

At State College last term, 57 of the students in a Physics course earned As, 79 earned Bs, 102 got Cs, 94 were issued Ds, and 53 failed the course. If this grade distribution was graphed on a pie chart, how many degrees would be used to indicate the A region?

Answer 1

Given:-

57 students in a physics course earned A.

79 students course earned B.

102 students course earned C.

94 students course earned D.

53 students failed the course.

To find:-

How many degrees would be used to indicate the region A.

Total number of students is,

`57+79+102+94+53=385`

Now we find the degrees to indicate the region A. we get,

`(57)/(385)*360=0.1480*360=53.29`

So the required soluion is 53.29 degrees.
