Joel is constructing a line perpendicular . He has already constructed three arcs as shown. Use the image to answer the question
. He moves his compass point to W to construct a fourth arc.

It must be narrower than it was when constructing the arc above P.
It must be the same as it was when constructing the arc above P.
It must be wider than it was when constructing the arc above P.

Answer:
- North Middle School = 10 students
- Central Middle School = 6 students
- South Middle School = 4 students
Step-by-step explanation:
First calculate the total number of students in all the schools:
= 618 + 378 + 204
= 1,200 students
Use this number to calculate the proportion of the total population that a school so that this can then be used to determine the proportion of the 20 delegates they should sent.
North Middle school:
= 618/1,200 * 20
= 10 students
Central Middle School:
= 378 / 1,200 * 20
= 6 students
South Middle School:
= 204/1,200 * 20
= 4 students
