Answer:

  • C. -x^3 + x^2 - 1

Step-by-step explanation:

<u>Given</u>

  • u(x) = x^5 - x^4 + x^2 and v(x) = -x^2

<u>(u/v)(x) = </u>

  • (x^5 - x^4 + x^2) /(- x^2) =
  • - (x^3 - x^2 + 1) =

A bag contains 40 marble 12 red and 16 yellow what is the probability that a blue is randomly seclected
lora16 [44]

Answer:

Fraction=3/10

Decimal=0.3

Percent=30%

Step-by-step explanation:

First we have to add 12+16 so we can find how many marbles are left

12+16=38

Then, we subtract it from the total number of marbles.the outcome of this operation would be equivalent to the number of blue marbles

40-38=12

There are 12 blue marbles.

Now, the we have to use experimental probability if you are familiar with the term is that the number of outcomes(the blue marbles) must be over the total sample space(total marbles) in a fraction.

Probability=

12/40

Simplify

12/40

6/20

3/10

Probability

Fraction=3/10

Decimal=0.3

Percent=30%
