Answer:
Salary: $90,500
Step-by-step explanation:
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 problem, we have that:
![\mu = 80000, \sigma = 8450](https://tex.z-dn.net/?f=%5Cmu%20%3D%2080000%2C%20%5Csigma%20%3D%208450)
An employee was having their annual appraisal and the manager indicated that the employee salary for next year has a Z-score of 1.24. Approximately how much will this employee be paid next year in salary?
This is X when
. So
![Z = \frac{X - \mu}{\sigma}](https://tex.z-dn.net/?f=Z%20%3D%20%5Cfrac%7BX%20-%20%5Cmu%7D%7B%5Csigma%7D)
![1.24 = \frac{X - 80000}{8450}](https://tex.z-dn.net/?f=1.24%20%3D%20%5Cfrac%7BX%20-%2080000%7D%7B8450%7D)
![X - 80000 = 1.24*8450](https://tex.z-dn.net/?f=X%20-%2080000%20%3D%201.24%2A8450)
![X = 90478](https://tex.z-dn.net/?f=X%20%3D%2090478)

Salary: $90,500
Answer:
x < - 1
Step-by-step explanation:
Given
- 4x > 4
Divide both sides by - 4, reversing the symbol as a result of dividing by a negative quantity.
x < - 1
