A z-score is the number of standard deviations from the mean a data point is. But more technically it’s a measure of how many standard deviations below or above the population mean a raw score is
The z scores are numbers without units of measurement
therefore
the answer is the option D

Answer:
(-1, 4)
Step-by-step explanation:
2x+5(-3x+1)=18
2x-15x+5=18

-13x=13
x=-1
-3(-1)+1
3+1
y=4
