Answer:
2308.4mm^3
Step-by-step explanation:
V=(4/3)πr^3
V = (4/3)π8.2^3
V= (4/3)π x 551.368
V = 2308.39
(2308.4 if rounded to tenths)
I believe the correct answer is 6,240 so you had subtract 260 from 6500
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.
