Answer:

a. 72

Step-by-step explanation:

Factorial (!) means take that number and multiply by all the numbers below it to 1

9! = 9*8*7*6*5*4*3*2*1

(9-2)! = 7! = 7*6*5*4*3*2*1

9*8*7*6*5*4*3*2*1

------------------------------

7*6*5*4*3*2*1

Canceling common factors

9*8

Answer:

Rounded to the nearest integer, the test had 18 problems in all.

Step-by-step explanation:

100 - 44 = 56

56 = 10

100 = X

100 x 10/56 = X

1,000 / 56 = X

17.85 = X

Thus, rounded to the nearest integer, the test had 18 problems in all.
