Z = 75

You can simply do the reverse operation of this, which would be division, and find the answer that way. 15/0.2 is 75 and that's your answer! You can check by doing "75 x 0.2", which would give you 15, your starting answer. Hope this helped!

Answer:

B) 4,320

Step-by-step explanation:

You would first find the volume of the triangular prism using this formula:

V = 1/2 x A x C x H

A = 3 C = 6 H = 24

V = 1/2 x 3 x 6 x 24 = 216 cubic feet

Since there are 20 pounds of snow per cubic foot, you multiply the cubic feet (216) by the pounds of snow per cubic foot (20):

216 x 20 = 4,320 pounds

What are the related frequencies to the nearest hundredth of the columns of the two way table?
Eddi Din [679]

Answer: The relative frequency of column A in group 1=0.75

The relative frequency of column B in group 1=0.25

The relative frequency of column A in group 2=0.56

The relative frequency of column B in group 2=0.44

Step-by-step explanation:

The relative frequency is the ration of each frequency by the total value in particular group.

For group 1 : Total =102+34=136

The relative frequency of column A in group 1=\frac{102}{136}=0.75

The relative frequency of column B in group 1=\frac{34}{136}=0.25

For group 2 : Total =18+14=32

The relative frequency of column A in group 2=\frac{18}{32}=0.5625\approx0.56

The relative frequency of column B in group 2=\frac{18}{32}=0.4375\approx0.44
