Volume of a rectangular prism is V = L x W x H

The length for the small prism is 6

The width for the small prism is 4

The height for the small prism is 3

So 6 x 4 x 3 = 72

The length for the large prism is 16

The width for the large prism is 9

The height for the large prism is 2

So 16 x 9 x 2 = 288

Now you add the two volumes together: 288 + 72 = 360 ft cubed.

8x + 7y = -15 (1st)
-7x - 9y = -7 (2nd)

multiply (1st) by 7 and (2nd) by 8

56x + 49y = -105 (multiply 7)
-56x - 72y = -56 (multiply  8)
--------------------------------------------add
         -23y = -161
               y = 7

8x + 7y = -15
8x + 7(7) = -15
8x + 49 = -15
8x = -64
x = -8

answer
x = -8 and y = 7

jek_recluse [69]

Answer:

4.19

Step-by-step explanation:

Find the mean:

\text{Mean}=\frac{12+19+9}{3}=\frac{40}{3}

Find the standard deviation:

\text{Standard Deviation}=\sqrt{\frac{(12-\frac{40}{3})^2+(19-\frac{40}{3})^2+(9-\frac{40}{3})^2}{3}}=\sqrt{\frac{158}{9}}\approx4.19
