Step-by-step explanation:
I think the simplest way to do this is as follows:
divide 75 by 15 to get how many times you need to multiply 2in by
75/15=5
since 15(5)=75 or the actual size of the airplane,
2(5)=10 which is the size of the model airplane
10 cups (there are 4 cups in a quart, so 4+4+2)
5 pints (there are 2 pints in a quart, so 2+2+1)
(x+5)(x+2) is your answer
Answer:
C.
Step-by-step explanation:
The random variable W is Normal, with a mean of 28 ounces and a standard deviation of four ounces.

Variance of total = 4+4+4+4 = 16
SD of total = sqrt(16) = 4
