Answer:
1/5
Step-by-step explanation:
Equation: 
Points: (-3, -9) and (22, -4)
is the second y point that shows up on the question, basically go by order. So it's -4
is -9, because again, in order of which coordinates pop-up first in the question
is 22, 
is -3
Now input into the equation, to make it easier we'll split the fraction into 2 equations:
= 
and 
, we'll put them back in a fraction later
= -4 - (-9) = -4 + 9 = 5
= 22 - (-3) = 22 + 3 = 25
now put it in the fraction, remember y on top x on the bottom:
5/25, simplify, 1/5
11)
3x = 180
x = 60
12)
6x + 18 = 180
6x = 162
x = 27
Answer:
As long as the sample size n is large enough: The average IQ of Americans in the sample will be normally distributed.
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a random variable X, with mean 
and standard deviation 
, the sample means with size n of at least 30 can be approximated to a normal distribution with mean and standard deviation 
So the correct answer is:
As long as the sample size n is large enough: The average IQ of Americans in the sample will be normally distributed.
