The formula for determining a z-score is z = (x-μ)/σ, where x is the raw score, z is the population mean, and z is the population standard deviation.
How to calculate a raw score when a z-score ?The raw score less the population mean, divided by the population standard deviation, is what the calculation reveals to be the z-score.We occasionally need to locate the raw score that corresponds to a z-score that we are aware of. A sample's z-score can be converted into a raw score using the following formula:X=(z)(SD) + mean
The formula demonstrates how to multiply the z-score by the standard deviation, then add that result to the mean.Verify if your response is logical: The raw score that corresponds to a negative z-score should be lower than the mean, and the raw score that corresponds to a positive z-score must be higher than the mean.To Learn more About z-score refer to:

Jamie is twice as old as Natalie now. Give years ago the sum of their ages was 26. How old is each person now?
answer:
8. 67 and 17. 36
step-by-step explanation:
hi there!
to find out the age of both girls, i believe that we should divide the number 26 by 3 because jamie is twice as old as natalie meaning ( natalie ) is younger
26/3
= 8. 67
meaning 8.67 is how old natalie is/was
add 8.68 to itself once and you will get jamie's age!
8. 67 + 8. 67
= 17. 34
meaning 17. 34 is how old jamie is/was

A line has a slope of 0 and passes through the point (-4, 3). What is its equation in slope-intercept form.
Answer:
y = 3
Step-by-step explanation:
We already know the slope, all we need to do is find the y-intercept.
You have to plug the coordinates into the equation, y = 0x + b
y = 0x + b
3 = 0(-4) +b
3 = 0 + b
3 = b
The equation is y = 3

home after 3 years.
a.$137027.97
b.$275503.80
c.$114449.19
d.$3385800
Answer:
The value after three years is $137,027.97
Step-by-step explanation:
Here, we want to get the value of the home after 3 years
Generally, we have the exponential formula as follows;
y = P(1 + r)^t
where P is the original cost which is $124,400
r is the rate of increase which is 3% = 3/100 = 0.03
t is the time which is 3 years
Substituting these values;
y = 125400(1 + 0.03)^3 = $137,027.97
