Answer:
88
Step-by-step explanation:

The mean would be the sum of all the math quiz grades divided by the number of quizzes taken.
Solve for x:



Thus, Allen needs at least an 88 to obtain a mean of at least 90.
Well the 2 in the tens place is ten times as many as the 2 in the hundreds place.Also the 5 in the thousand place is 10 times as many as the 5 in the ten thousand place
Answer:
no
Step-by-step explanation:
using the Factor theorem.
If (x + h) is a factor of f(x) then f(- h) = 0
for factor (x + 3) then evaluate P(- 3)
P(- 3) = (- 3)³ - 5(- 3)² + 3(- 3) + 9 = - 27 - 45 - 9 + 9 = - 72
since f(- 3) ≠ 0 then (x + 3) is not a factor of P(x)
I think it is D. it translates into .875 which is .88
256.5/18= 14.25
(14.25x2)+(18x2)= 64.5m
