The mean is the same thing as the average. To find the average, add all the numbers up (aka find the sum of the numbers) and divide by how many numbers there is:
average =  \frac{sum \: of  \: numbers}{\# \:  of  \: numbers}

So the sum of your numbers is: -6 + 2 + 5 + -7 + -11 + -6 = -23. And there are 6 numbers total.
That means average =  \frac{-23}{6} = -3.833333 ≈ -3.8

Your final answer is -3.8

How many unique triangles can be drawn with side lengths 8 in., 12 in., and 24 in.? Explain.
Elanso [62]

Answer:

2

Step-by-step explanation:

To figure this out, you must use the triangle inequality theorem. It says that the sum of 2 sides of the triangle should be more than the third side. If you add 8 and 12, you get less than 24 but if you add 12 and 24 or 8 and 24, you will get more. So, there are only 2 triangles! I hope this helps!

What is -2x + 12 divided by 4
Goshia [24]

Answer:

x=4

Step-by-step explanation:

First set the equation equal to 4:

-2x +12=4

Subtract 12 from both sides:

-2x +12=4

      -12  -12

-2x=-8

Then divide each side by -2 to isolate the x:

-2x/-2=-8/-2

x=4

Frozen apple juice comes in a cylindrical can. A can is 12 cm high and has a radius of 3.5 cm. What is the capacity of the can?
34kurt

Answer:

438.501cm^3

Step-by-step explanation:

Given data

Height of can= 12cm

Radius= 3.5cm

The capacity of the can is expressed as

V= πr^2h

V= 3.14*3.5^2* 12

V= 3.14*12.25*12

V= 461.58cm^3

Hence the capacity is 461.58cm^3

We are also given that the juice amount to 95% of the capacity of the can

95/100*461.58= x

0.95*461.58=x

x=438.501cm^3

This means that the volume of the juice is 438.501cm^3
