D
Step-by-step explanation:
sorry if i am incorrect but that is my best guess
The formula to calculate the z-score of a certain value is:
z = (x - (mean))/(standard deviation)
In this example, the x-value is 450, the S.D. is 100, and the mean is 500.
So, substitute these values into the formula.
z = (450-(500))/100
z=-50/100
z=-0.5
Therefore, the z-score is -0.5.
Answer: The answer is actually 8 4/7
Step-by-step explanation:
Because...
7/6y-8=2
Add the 8 to the other side
7/6y=10
You then have you divide 7/6y by 7/6, then do it to the other side giving you 60/7.
That gives you a mixed number of 8 4/7.
