Answer:
-4/3
Step-by-step explanation:
- -14 -8 = -2 (-3x + 7)
- -22= 6x-14
- 6x=14-22
- 6x=-8
- x= -8/6
- x= -4/3
Rise=+3
Run=+2
Slope=rise/run=3/2
equation:
y=3/2 x
Answer:
I will forward the challenge to the ISCAP.
Step-by-step explanation:
If the classifying agency does not provide a full response within 120 days, then as per my responsibility, I will forward the challenge to the ISCAP.
ISCAP is the Inter agency security classification appeals panel.
ISCAP is a deciding panel that decides on certain classification or declassification issues to its users, with a forum for further review.
Answer:
15 1/2=4+5+5=14+1/2=14 1/2+1/4=14 3/4+1/2=15 1/2
Answer:
And for this case we can use the complement rule and the normal standard distribution of excel and we got:
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".
Solution to the problem
Let X the random variable that represent the heights of a population, and for this case we know the distribution for X is given by:
Where and
And we select a sample size of n =70
From the central limit theorem (n>30)we know that the distribution for the sample mean is given by:
And we want to find this probability:
And we can use the z score formula given by:
And using this formula we got:
And for this case we can use the complement rule and the normal standard distribution of excel and we got:
