5 to the 3rd power is 125, therefore the choice is C
Answer: 9
Step-by-step explanation:
Based on the information given in the question, the expected number of people who pass will be calculated as:

= 9.75
Therefore, expected number of people who pass is 9.
Answer:
(4, -2)
Step-by-step explanation:
if you do process of elimination you find that 'a' doesn't work out but 'b' will . . . substitute -2 for 'y' and 4 for 'x' and see if the equation is true
-2 = -3/4(4) + 1
-2 = -3 + 1
-2 = -2
