Step-by-step explanation:
P(A or B) = P(A) + P(B) − P(A and B)
P(A or B) = 6/36 + 5/36 − 0/36
P(A or B) = 11/36
It will be 57 because if 9 are nickles in the rest are pennies
Answer:
425 miles per hour
Step-by-step explanation:
Find the speed per hour by dividing the distance by the number of hours:
6375/15
= 425
This means the plane traveled 425 miles in one hour.
So, the plane's average speed was 425 miles per hour
(x - 4)(x^2 + 3x + 2) =
x(x^2 + 3x + 2) - 4(x^2 + 3x + 2) =
x^3 + 3x^2 + 2x - 4x^2 - 12x - 8 =
x^3 -x^2 - 10x - 8
