Answer:
solution attached below
Step-by-step explanation:
Find the volume with the equation
v = length × width × height
For your cuboid
v = .4cm×1.5cm×3.25cm
v = 1.95 cm^3
Don't forget to always put your units!
Answer:
24 divided by 3 is 8
Step-by-step explanation:
3 goes into 24, 8 times
Variance is given by s^2 = [summation (x - mean)^2] / n.
mean = (90 + 75 + 72 + 88 + 85) / 5 = 82
Variance = [(90 - 82)^2 + (75 - 82)^2 + (72 - 82)^2 + (88 - 82)^2 + (85 - 82)] / 5
= [8^2 + (-7)^2 + (-10)^2 + 6^2 + 3^2] / 5
= (64 + 49 + 100 + 36 + 9] / 5
= 258 / 5
Therefore, the value of the numerator of the calculation of the variance of the data set is 258.
