Answer:
0.078 or 7.8%
Step-by-step explanation:
Mean salary (μ) = $37,764
Standard deviation (σ) = $5,100
The z-score for any given teacher's salary in California, X, is determined by:
![z=\frac{X-\mu}{\sigma}](https://tex.z-dn.net/?f=z%3D%5Cfrac%7BX-%5Cmu%7D%7B%5Csigma%7D)
For X = $45,000:
![z=\frac{45,000-37,764}{5,100}\\ z=1.419](https://tex.z-dn.net/?f=z%3D%5Cfrac%7B45%2C000-37%2C764%7D%7B5%2C100%7D%5C%5C%20z%3D1.419)
A z-score of 1.419 corresponds to the 92.20th percentile of a normal distribution. Therefore, the probability that a salary is greater than $45,000 is:
![P(X>\$45,000) = 1-0.9220\\P(X>\$45,000) = 0.078=7.8\%](https://tex.z-dn.net/?f=P%28X%3E%5C%2445%2C000%29%20%3D%201-0.9220%5C%5CP%28X%3E%5C%2445%2C000%29%20%3D%200.078%3D7.8%5C%25)
The probability is 0.078 or 7.8%.
Step-by-step explanation:
If you mean 5 + 3 over 4, then:
5 + 3/4 = 5 3/4.
_________________________________
If you mean 5 + 3 divided by 4, then:
5 + 3 = 8
8 divided by 4 = 2.
