X=9/2
Thank youu , 12-3 equals 9, then divide 2 and the answer is 9/2
Answer:C
Step-by-step explanation:
Answer:
12x + 40y
Step-by-step explanation:
4(3x+10y)
multiply the outer number (4) with all the terms inside the parentheses
4 X 3x + 4 X 10y
12x + 40y
Answer:
5
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:

On average, how much error would be expected between the sample mean and the population mean?
This is the standard deviation of the sample. We have that
. So

The answer is 5.
