It’s 12 cause the smaller triangle is smaller by times 3 so if u multiply all those and the missing one would be 12 cause 4 times 3 is 12

If 11.25 inches snow fell in 4.5hrs,
Then for each hr how much snow fell?
So,
4.5 : 11.25
To find how many inches that fell per hour who would need to divide the number of inches by the numbers of hours
11.25 divided by 4.5 = 2.5
So the answer would be 2.5 inch was of snow per hour
Answer:
Step-by-step explanation:
Given that the height in inches, of a randomly chosen American woman is a normal random variable with mean μ = 64 and variance 2 = 7.84.
X is N(64, 2.8)
Or Z = 
a) the probability that the height of a randomly chosen woman is between 59.8 and 68.2 inches.

b) 
c) For 4 women to be height 260 inches is equivalent to
4x will be normal with mean (64*4) and std dev (2.8*4)
4x is N(266, 11.2)

d) Z is N(0,1)
E(Z19) = 
since normal distribution is maximum only between 3 std deviations form the mean on either side.
