Answer:
3
Step-by-step explanation:
Because when you draw the Z in the diagram you will see that three and four are outside which means it is corresponding
This sample size it too small. The larger the sample size, the more likely the data will be true to what the question is asking. A larger sample size brings more precision to the question that is being asked.
Answer:
Depth = 3 inches
Maximum cross-sectional area = 18 inches²
Step-by-step explanation:
Let 'D' be the depth of the gutter and 'W' be the width of the gutter, the cross-sectional area as function of depth, A(D), is:
The depth for which the derivate of the area function is zero is the depth that yields the maximum cross-sectional area:
The cross-sectional area for D = 3 is:
Answer:
V = 549.25 pi = 1,724.645in^2
Step-by-step explanation:
If both the base and height are equal, then you must use the given equation:
V = pi * r^2 * h
V = pi * (1/2 13)^2 * 13
V = pi * 6.5^2 * 13
V = 549.25 pi = 1,724.645in^2
