Step-by-step explanation:
I would think Kaylee is 5 since 12 divided by 3 is 4 and 4 * 2 is 8, and 8-3 is 5. So, I would think Kaylee is 5.
Answer: T=-3 5/12
Step-by-step explanation: 6 1/3-6 /13
6 1/3-9 3/4= -3 5/12
T= -3 5/12
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.
