Answer:
States sent representatives to Congress and provided soldiers and some officers to protect the country.
Answer:
Step-by-step explanation:
1) 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 the scores, 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
2) Calculate the probability
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:
-9,-3,3,9,-9,-3,3,9 so forth until -3
Answer:
33x
Step-by-step explanation:
Add the known values
15 and 10 equals 25. 25 + 6 is 31. And 31 plus 2 is 33.
Then return the unknown value so your answer is 33x
