Question

The frequency table above is presented as a pie chart

Answer 1

Answer:

$Angle = 96$

Step-by-step explanation:

Given

The frequency table

Required:

Determine the sectorial angle of "3"

First we need to determine the total frequency;

$Total = 3 + 4 + 6 +8 + 5 + 4$

$Total = 30$

The sectorial angle is calculated as thus;

$Angle = \frac{Frequency}{Total\ Frequency} * 360$

Where Frequency of "3" = 8

So;

$Angle = \frac{8}{30} * 360$

$Angle = \frac{8* 360}{30}$

$Angle = \frac{2880}{30}$

$Angle = 96$

Hence; the sectorial angle of "3" is 96
