Answer: I think the answer is -x + y.

Step-by-step explanation:I think this is the answer because you first start off by distributing all the variables inside the parenthesis by the negative sign which would give you -x+2y-y. After that, you would have to subtract 2y-y because they share the same variable and you must have a SIMPLIFIED ANSWER. So with that said, your overall answer should be -x+y. Hope I'm right in giving you the correct answer!!!!

The means and mean absolute deviations of the individual times of members on two 4x400-meter relay track teams are
Phoenix [80]

Answer:

9%

Step-by-step explanation:

To find the percentage of Team B's mean absolute deviation difference in the means, you have to subtract the two means, <u>59.32-59.1.</u>

After this, divide your answer the the mean absolute deviation of Team B, or you could put it all in the calculator or paper like this:

\frac{59.32-59.1}{2.4}

You'd then end with the decimal: .0916, which you would multiply by 100 to get about 9%

What is the volume of a volleyball with a diameter of 8 inches
natita [175]

Hello there!

We are going to follow the volume of a sphere since a volleyball is a sphere. V=4/3πr^3 is the formula for finding the volume of a sphere. The only unknown value is r, or the radius. We find the radius by halving the diameter.

8/2 = 4, so we have a radius of 4 inches.

Place the value of 4 in for r - V = 4/3 x π x (4)^3

Now solve.

V = 4/3 x π x (4)^3

Start by squaring 4.

V = 4/3 x π x 64

Next, multiply 4/3 by 64. (<em>you can do it in any order since there are no parenthesis</em>)

V = π x 85.33

Lastly, multiply 85.33 by pi.

V = 268.08

So, your answer is approximately 268.08, since we used rounding it is not exact. I hope this was helpful and have a great rest of your day! :)
