If you’re trying to find the value of x it is -5
Answer:B.) Bisector Of An Angle
Step-by-step explanation:
Answer:
By the Central Limit Theorem, the mean is 78, the standard deviation is
and the shape is approximately normal.
Step-by-step explanation:
Central Limit Theorem
The Central Limit Theorem establishes 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.
Mean of 78 and a standard deviation of 6
This means that 
Samples of n:
This means that the standard deviation is:

What are the mean, standard deviation, and shape of the distribution of x-bar for n?
By the Central Limit Theorem, the mean is 78, the standard deviation is
and the shape is approximately normal.
So I think the rule is that you divide two exponents with the same base, you keep the base and subtract the powers.
6 × (13 - 6) = 42, not 7, but 7² is 49 and 42² is 1,764.
I hope this helps!
