Answer:
12:45 PM
Step-by-step explanation:
First, add the time of the math class:
10:15 AM + 1 hour
= 11:15 AM
11:15 AM + 55 minutes
= 12:10 PM
Then, add the time of recess:
12:10 PM + 35 minutes
= 12:45 PM
So, her recess ends at 12:45 PM

Answer: 5
Step-by-step explanation:
We know that the standard deviation of the sampling distribution of the means is given by :_
![SE=\sigma_x=\dfrac{\sigma}{\sqrt{n}}](https://tex.z-dn.net/?f=SE%3D%5Csigma_x%3D%5Cdfrac%7B%5Csigma%7D%7B%5Csqrt%7Bn%7D%7D)
Given : The average weekly earnings for employees in general automotive repair shops is
.
The standard deviation for the weekly earnings for such employees =
Now, the standard deviation of the sampling distribution of the means of average weekly earnings for samples of size
:-
![SE=\sigma_x=\dfrac{50}{\sqrt{100}}\\\\\Rightarrow\ SE=\dfrac{50}{10}\\\\\Rightarrow\ SE=5](https://tex.z-dn.net/?f=SE%3D%5Csigma_x%3D%5Cdfrac%7B50%7D%7B%5Csqrt%7B100%7D%7D%5C%5C%5C%5C%5CRightarrow%5C%20SE%3D%5Cdfrac%7B50%7D%7B10%7D%5C%5C%5C%5C%5CRightarrow%5C%20SE%3D5)
Hence, the standard deviation of the sampling distribution of the means of average weekly earnings for samples of size 100 = 5
