The number of degrees that would be used to indicate region A is 53°
EXPLANATION
Number of students with As = 61
Number of students with Bs = 89
Number of students with Cs =119
Number of students with Ds = 79
Number of students with F = 70
To find the number degrees that would be used to indicate A region, we will use the formula below:
[tex]\text{ Region A in degre}e=\frac{Number\text{ of As}}{\text{Total number of student}}\times360^o[/tex]Number of As = 61
Total number of students = 61 + 89 + 119 + 79 + 70 = 418
Substitute the values into the formula and evaluate.
[tex]A\text{ region in degre}e=\frac{61}{418}\times360^o[/tex][tex]=52.55885[/tex][tex]\approx53^o\text{ to the nearest degre}e[/tex]Therefore, the number of degrees ithat would be used to indicate region A is 53°
