4y - 7 = 5 - 2y
Add 2y to both sides.
6y - 7 = 5
Add 7 to both sides.
6y = 12
Divide both sides by 6
y = 2
This question is asking you for the least common multiple of 60 (seconds in 1 minute) and 24 (seconds in 24 seconds).
I think it's 120 (you should check it) and that would be 3 minutes.
The answer is function, not a function, function, not a function, and function based on the picture you have provided
Using z-scores, it is found that all of the values fall within 2.46 standard deviations of the mean.
<h3>What is the z-score formula?</h3>
The z-score of a measure X of a variable with mean
and standard deviation
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 above or below the mean.
In this problem, the farthest variable from the mean is of $29.95, hence X = 29.95 and:
![Z = \frac{X - \mu}{\sigma}](https://tex.z-dn.net/?f=Z%20%3D%20%5Cfrac%7BX%20-%20%5Cmu%7D%7B%5Csigma%7D)
![Z = \frac{29.95 - 22.58}{3}](https://tex.z-dn.net/?f=Z%20%3D%20%5Cfrac%7B29.95%20-%2022.58%7D%7B3%7D)
Z = 2.46.
Hence, all of the values fall within 2.46 standard deviations of the mean.
