B because 14-5=9 and 9-8= 1
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.
All you have to do, is combine like terms. Let's go through it:

Arrange it so you can easily combine like terms:

So, your answer for the sum is 1) 7x² - 10x + 2
Answer:
Hi! I suggest reading the explanation, it will help make this equation more simple.

The answer is $45.50
Step-by-step explanation:
First, divide 26.00 by four. This will give you 6.5, so now you know that each ticket individually costs $6.5 or $6.50.
next, multiple 6.50 by 7.
this will give you 45.5 or $45.50.
double check your answer by dividing 45.50 by 7.
your answer should be 6.5 on a calculator.
that's all! hope this helped.
