Answer:

B. The variable s represents the number of students in each class.

C. The coefficient 14 represents the number of classes in the 9th grade.

Step-by-step explanation:

The total number can be found by multiplying the number of the things with the number of people producing it. For example if 5 boys make 5 colored ropes the total number of ropes will be 5*5= 25.

In this question the combinations rule is used for variuos number of classes which are 14. Now we have to find the number of students which are s (s-1). Suppose s= 6 so the number of students would be 6(6-1) = 6(5) = 30

We will multiply the number of classes 14 with the number of students s(s-1) to get the total number of cards produced.

To calculate average of people per year that gained bachelor degree sum all data given per year and divide with the number of years data was recorded.

$\frac{4033 + 5652 + 6407 + 7201 + 8719 + 11154 + 15121}{7} = \frac{58287}{7}$
$\frac{58287}{7} = 8326.714$
