To find the mean score, add all the numbers together and divide by the amount of numbers there is.

6.856 + 7.923 + 8.135 = 22.914

Divide 22.914 by 3

22.914/3 = 7.638

7.638 is your answer

hope this helps

Choose the table that represents g(x) = −2⋅f(x) when f(x) = x + 4.
grigory [225]

Answer: THIRD OPTION.

Step-by-step explanation:

Since  g(x) = -2f(x), then g(x) is:

g(x)=-2( x + 4)\\\\g(x)=-2x-8

In order to find which table represents g(x) = -2f(x) when f(x) = x + 4, you can follow these steps:

1. Substitute x=1 into the function g(x)=-2x-8:

 g(1)=-2(1)-8\\\\g(1)=-10

2. Substitute x=2 into the function g(x)=-2x-8:

 g(2)=-2(2)-8\\\\g(2)=-12

3. Substitute x=3 into the function g(x)=-2x-8:

 g(3)=-2(3)-8\\\\g(3)=-14

Notice that those ouput values (for x=1,\ x=2 and x=3) matches with the table provided in the third option. That table represents g(x) = -2f(x) when f(x) = x + 4:

<u>To Find</u>:

The Volume of a Cone

<u>Formula</u>:

The Formula for the volume of a cone is

V=πr2 *h/3

<u>Solution</u>:

V=πr2 *h/3

π value is 3.14

V= 3.14*(3)^2*9/3

V=3.14*9*3

V= 84.78 cm

Therefore the volume is 84.78 cm.
