Answer:

Step-by-step explanation:
Given,
, solve for x.
Multiply both sides by 2


Add x to both sides


You can factor this by taking out the GCF (greatest common factor).
In the expression, the greatest common factor between the two terms is 5.
Take out 5:
5(2b + 5)
Is it possible to factor 2b + 5 even more?
No. So, your answer is D. 5(2b + 5).
Answer:
Step-by-step explanation:
Previous concepts
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".
Let X the random variable that represent interest on this case, and for this case we know the distribution for X is given by:
And let
represent the sample mean, the distribution for the sample mean is given by:
On this case
Solution to the problem
We want this probability:
The best way to solve this problem is using the normal standard distribution and the z score given by:
If we apply this formula to our probability we got this:
Answer:
multiply all those numbers together
