Answer:
I think is 8.787e+6 cubic inches.
Answer:

Step-by-step explanation:
From the question we are told that:
Sample size 157
Sample mean



Generally the equation for Standard deviation is mathematically given by



Therefore



Answer :
-3x +6 -4
= -3x +2
Answer:
a=1/2
Step-by-step explanation:
From the question, the expression a(8x+7) is equivalent to 4x+3.5
Which means that multiplying 8x by a gives 4x and multiplying 7 by a gives 3.5
So, we can write the following to find the value of a

we can write the following
8ax=4x

Hence the value of a is 1/2
