Z-score is given by the formula:
z=(x-μ)/σ
where:
μ-mean
σ-standard deviation
thus the z-score for the data set with mean 13 and standard deviation of 2.5 will be:
z=(10-13)/2.5
z=-1.2

Solve ry + s = tx - m for y. Explain each step in your solution.
sergeinik [125]

y = (t x - m -s)/r

Step-by-step explanation:

Step 1 :

Given,

r y + s = t x - m

=> r y = t x - m -s

=>  y = (t x - m -s)/r

Step 2 :

A) r can take any values except 0.

This is because when r = 0, the denominator becomes 0 and division by 0 is undefined

The limitation for r is r should not be equal to 0

The other variables can take any value. Hence the other variables do not have any limitation
