Step-by-step explanation: Hope this helps!
It would be A because -2.25*3=-6.75 and -2.25*x=-2.25x giving us are end answer of, -6.75+2.25x
Enjoy!=)
(P.s. I am not 100% sure if this is completely factored but it should be)
Answer:
-7/x
Step-by-step explanation:

Answer:
See below. Sean is in error.
Step-by-step explanation:
There are a total of 15 rolls of the cube.
If we count the number of 1's that are rolled we get 5 which is more than any other number. So the EXPERIMENTAL probability of getting a 1 is 5/15 = 1/3.
But this is NOT the THEORETICAL probability.
If we assume that it is a fair cube then the theoretical probability of a 1 is 1/6.
Each number has an equal theoretical probability of 1/6.
