At State College last term, a large number of students completed a Spanish course. 70 of the students earned As, 84 earned Bs, 105 got Cs, 76 were issued Ds, and 32 students failed the course. If this grade distribution was graphed on a pie chart, how many degrees would be used to indicate the D region?

Answer:


75\degree

Step-by-step explanation:

Here, we want to get the degree on the piechart for stuedents in the D grade region

What we have to do here is to divide the count of students in the D region by the total count of students, then multiply the quotient by 360 degrees

Mathematically, we have this as:


(76)/(70+84+105+76+32)*\text{ 360 = 74.55}\degree

The degrees used to indicate the D region is approximately 75°
