Step-by-step explanation:
The answer is 9, a square has 4 equal sides so you do 36 divided by 4 and you get 9
Answer:
d. 200 and 2
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean
and standard deviation
, the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean
and standard deviation
.
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
In this problem, we have that:
Mean = 200
Standard deviation = 18
Sample size: 81
Standard error: 
So the correct answer is:
d. 200 and 2
<h3>step 1.</h3>
use graph paper.
<h3>step 2.</h3>
draw lines thru the graph wait go on my image above!
3x+ 8= x-4
2x + 8= -4
2x= -12
x= -6
