Step-by-step explanation:
![3x+2m-y=V\qquad\text{add}\ y\ \text{to both sides}\\\\3x+2m-y+y=V+y\\\\3x+2m=V+y\qquad\text{subtract}\ 3x\ \text{From both sides}\\\\3x-3x+2m=V+y-3x\\\\2m=V+y-3x\qquad\text{divide both sides by 2}\\\\\dfrac{2m}{2}=\dfrac{V+y-3x}{2}\\\\m=\dfrac{V+y-3x}{2}](https://tex.z-dn.net/?f=3x%2B2m-y%3DV%5Cqquad%5Ctext%7Badd%7D%5C%20y%5C%20%5Ctext%7Bto%20both%20sides%7D%5C%5C%5C%5C3x%2B2m-y%2By%3DV%2By%5C%5C%5C%5C3x%2B2m%3DV%2By%5Cqquad%5Ctext%7Bsubtract%7D%5C%203x%5C%20%5Ctext%7BFrom%20both%20sides%7D%5C%5C%5C%5C3x-3x%2B2m%3DV%2By-3x%5C%5C%5C%5C2m%3DV%2By-3x%5Cqquad%5Ctext%7Bdivide%20both%20sides%20by%202%7D%5C%5C%5C%5C%5Cdfrac%7B2m%7D%7B2%7D%3D%5Cdfrac%7BV%2By-3x%7D%7B2%7D%5C%5C%5C%5Cm%3D%5Cdfrac%7BV%2By-3x%7D%7B2%7D)
Answer:
20.27
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a random variable X, with mean
and standard deviation
, the sample means with size n of at least 30 can be approximated to a normal distribution with mean
and standard deviation ![s = \frac{\sigma}{\sqrt{n}}](https://tex.z-dn.net/?f=s%20%3D%20%5Cfrac%7B%5Csigma%7D%7B%5Csqrt%7Bn%7D%7D)
Using the Central Limit Theorem for Means, what is the standard deviation for the sample mean distribution?
This is s when
. So
![s = \frac{136}{\sqrt{45}} = 20.27](https://tex.z-dn.net/?f=s%20%3D%20%5Cfrac%7B136%7D%7B%5Csqrt%7B45%7D%7D%20%3D%2020.27)
So the correct answer is:
20.27
