- 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

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

Answer:
The temperature at 9:00 is 14° C.
Step-by-step explanation:
At noon, the temperature was 6° C.
By 5:00, the temperature had dropped to -2° C.
Every hour until 9:00, the temperature rose 4°, so 4•4 is 16.
16 + -2 is 14.
So, the temperature at 9:00 is 14° C.
