A survey of 100 high school students provided this
HACTEHA [7]

Answer:

35/100

Step-by-step explanation:

You have to find how many juniors there are, so if you add 13, 20, and 2 you get 35. For the denominator you have to find the total number of students, so just add all of the numbers together to get 100. So there is a 35/100 chance that a randomly selected student is a junior.

What is the additive inverse of -7x2 + y?<br><br> 7x2 + y<br> 7x2 − y<br> 7x − y<br> -7x2 − y
Genrish500 [490]
Additive inverse is the number that when added to a number yields 0.

This is the negation of that number or expression.

The additive inverse of 7x^2 + y is -(7x^2 + y)

Distribute the negative sign across all the terms in the parentheses. This is the same thing as multiplying each term by -1.

-(7x^2 + y)
(-1 * 7x^2) + (-1 * y)
-7x^2 - y
