Pretty sure it is altitude sorry if im wrong
Answer: 1.79
Explanation:Let x = hourly wage for a social worker. Then, the z-score for x is given by
![\text{z - score} = \frac{x - \mu}{\sigma}](https://tex.z-dn.net/?f=%5Ctext%7Bz%20-%20score%7D%20%3D%20%20%5Cfrac%7Bx%20-%20%5Cmu%7D%7B%5Csigma%7D%20)
where
![\mu = \text{ mean hourly wage of a social worker }= \$ 28.08 \\ \sigma = \text{ standard deviation of the wage of the social worker }= \$ 1.97](https://tex.z-dn.net/?f=%5Cmu%20%3D%20%5Ctext%7B%20mean%20hourly%20wage%20of%20a%20social%20worker%20%7D%3D%20%5C%24%2028.08%0A%5C%5C%20%5Csigma%20%3D%20%5Ctext%7B%20standard%20deviation%20of%20the%20wage%20of%20the%20social%20worker%20%7D%3D%20%5C%24%201.97)
Since Jeronica's salary is $31.60, the z-score of Jeronica's is given by
Find the Greatest Common Factor (GCF)
GCF = 14
Factor out the GCF (Write the GCF first, and then in parenthesis, just divide each term by the GCF)
14(140c/14 + 28/14 + -14a/14)
Simplify each term in parenthesis
<u>14(10c + 2 - a) </u>
I believe the answer is 4 hours hope i helped
