<h3>Answer: Choice B</h3>

Consider that choice B is the same as saying 2x^2+1x^0.

The exponents 2 and 0 are both even, which is sufficient to say that the entire polynomial function itself is also even.

Something like choice A expands out and simplifies to x^2-2x+2, and that's equivalent to saying x^2+2x^1+2x^0. The presence of the x^1 term, with its odd exponent, is what makes choice A not even (it's not odd either).

Similarly, choices C and D also have exponents of 1, so they aren't even either.

A student has earned scores of 87, 81, and 88 on the first 3 of 4 tests. If the student wants an average (arithmetic mean) of ex

Juli2301 [7.4K]

To find an average you take the numbers to be averaged and add them together then You take the number and divide it by the number of numbers, in this case 4, and that gives you the average.
on this problem you want to do the opposite. you know the average she wants, an 87, so you multiply it by 4. 87*4=348. then you add the three numbers you have (88,81 and 87) and you get 256.
then you subtract 256 from 348 and you get 92. 92 is your answer to check just add 87+81+88+92=348
348/4=87
87 was the average she wanted.
Hope this helped! good luck :)

Use the drawing tool(s) to form the correct answer on the provided number line. Will brought a 144-ounce cooler filled with wate

BARSIC [14]

Answer:

Total amount of water in cooler = 144 ounce

Amount of water used to fill his bottle = 16 ounce

Amount of water filled in single plastic cup = x ounce

Total number of cups = 16

The equation for the given information is

⇒ 16 + 16 x=144

⇒16 x=144- 16

⇒ 16 x=128

⇒ x= 128÷16

⇒ x=8

Amount of water in each cup= 8

It is not mentioned that after filling 16 plastic cups is there water left in cooler.

If water is left in cooler after filling 16 plastic cups, suppose it's volume is y -ounce.

Then the equation becomes

⇒144=16 +16 x + y

⇒ 16 x + y =144-16

⇒16 x + y =128

So it is equation in two variables , so for different amount of water left in cooler(y), there will be be different ounces of water in plastic cups(x).
