Answer:
The minimum score required for the job offer is 751.
Step-by-step explanation:
When the distribution is normal, we use the z-score formula.
In a set with mean
and standard deviation
, the zscore of a measure X is given by:
![Z = \frac{X - \mu}{\sigma}](https://tex.z-dn.net/?f=Z%20%3D%20%5Cfrac%7BX%20-%20%5Cmu%7D%7B%5Csigma%7D)
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this question, we have that:
![\mu = 587, \sigma = 152](https://tex.z-dn.net/?f=%5Cmu%20%3D%20587%2C%20%5Csigma%20%3D%20152)
What is the minimum score required for the job offer?
Top 14%, so the minimum score is the 100-14 = 86th percentile, which is X when Z has a pvalue of 0.86. So X when Z = 1.08.
Then
![Z = \frac{X - \mu}{\sigma}](https://tex.z-dn.net/?f=Z%20%3D%20%5Cfrac%7BX%20-%20%5Cmu%7D%7B%5Csigma%7D)
![1.08 = \frac{X - 587}{152}](https://tex.z-dn.net/?f=1.08%20%3D%20%5Cfrac%7BX%20-%20587%7D%7B152%7D)
![X - 587 = 1.08*152](https://tex.z-dn.net/?f=X%20-%20587%20%3D%201.08%2A152)
![X = 751.16](https://tex.z-dn.net/?f=X%20%3D%20751.16)
Rounding to the nearest whole number:
The minimum score required for the job offer is 751.
Area= (1 side)^2
⇒ 2.25 in^2= (1 side)^2
⇒ 1 side= √(2.25) in
⇒ 1 side= 1.5 in

answer: nine pies
work: this question is pretty simple. manner has 12 pies, and three are being taken away. and since 12 - 3 = 9 he'll have 9 pies leftover.
