Step-by-step explanation:
2 x 2= 4, no. of 2s= 2
2 x 2 x 2= 8, no. of 2s= 3
2 x 2 x 2 x 2= 16, no. of 2s= 4
2 x 2 x 2 x 2 x 2= 32, no. of 2s= 5

Answer:
-1.58
Step-by-step explanation:
We have that the mean (m) is equal to 89 and the standard deviation (sd) 2.4
They ask us for P (x <85.2)
For this, the first thing is to calculate z, which is given by the following equation:
z = (x - m) / (sd)
We have all these values, replacing we have:
z = (85.2 - 89) / (2.4)
z = -1.58
I mean 9 is a composite number
Answer:
2y^3-7y^2+7y
Step-by-step explanation:
7y - 2y^3 + 5y^2 - ( 12y^2 – 4y^3)
Distribute the minus sign
7y - 2y^3 + 5y^2 - 12y^2 + 4y^3
Combine like terms
2y^3-7y^2+7y
