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
Answer:
The answer for 10 is y= -4x+2
If the slope is exactly the same but the y intercept is different then it will be parallel
The answer for 11 is y-5=-3/2 (x-1)
Step-by-step explanation:
I think its 50 percent. Hope this helps.
Answer:
Last choice
Step-by-step explanation: Subtract 11 and then divide by 3. A would be greater than -2 and last choice shows that
Area of a rectangle is A=l*w so you have 5 and 7 you times that and you get 35 squared inches
