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
1195 boxes are needed to ship all the tables
<em><u>Solution:</u></em>
Given that, furniture store received an order for 8,367 tables
They can fit 7 tables in the lower shipping box
To find: Number of shipping boxes needed to ship all the tables
From given,
Total number of tables = 8367
Number of tables fit in one shipping box = 7
Thus, we can find the number of shipping boxes needed to ship all the tables by dividing total number of tables by number of tables fit in one shipping box
Substituting the values we get,
Thus 1195 boxes are needed to ship all the tables
