320 is on the Fourth quadrant:)
I'm afraid I don't see the models you have written about although I do know the answer. (C= Courtney's age, S= Shilo's age)
Shilo is 7 years older then Courtney, which equals to C+7=S.
While at the same time Shilo is 13 years younger then twice Courtney's age. This turns into Cx2-13=S.
c+7=cx2-13. This is the equation, now lets work it out.
Add 13 on each side and you get
c+20=2c
Now we subtract c from each side and we get
20=c Therefor we have found out that Courtney is 20 years old.
Shilo being 7 years older then Courtney is 27
Problem: 7/10 - 1/2
1/2 = x/10 Find the common denominator
1/2 = 5/10
Subtract the numerators
7-5
Answer: 2/10
Simplest form: 1/5
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.
