Answers

Answer:

A pie chart

Explanation:

A pie chart can simply be used to measure and represent her observation. From the given parameters;

the total number of students = 15

Number of students that said 10pm = 9

using the pie chart; we take each measure to be fraction of the angles in a circle.

Angle subtended by the 9 students  = (9)/(15) x 360 = 216°

Answer:

central angle measured is 60%

Explanation:

Given information

Total number of 15 student out of which 9 said , they go to bed at 10 p.m

To represent the group on circle follow following steps
