The polynomial f(x) is written in factored form:
qaws [65]

Answer:

x = 6, x = -5, x = 9

if f(x)=(x-6)(x+5)(x-9)

Step-by-step explanation:

The zeros of a polynomial in factored form can be found by setting the polynomial equal to zero and then realizing if a product is zero, then at least one of it's factors is zero.

So we have the zero's are the x's that satisfy

(x-6)(x+5)(x-9)=0.

We just need to solve three equations:

x-6=0

           This can be solved by adding 6 on both sides:  x=6

x+5=0

         This can be solved by subtracting 5 on both sides: x=-5

x-9=0

         This can be solved by adding 9 on both sides: x=9

The solutions are in { 6,-5,9 }.

A bag contains five red marbles, two orange marbles, one yellow marble, and two green marbles. Two marbles are drawn from the ba
Naya [18.7K]

Option C: 0.8889 is the probability of choosing an orange marble and a green marble.

<h2>Given that:</h2>
  • Number of red marbles is 5
  • Number of orange marbles is 2
  • Number of yellow marbles is 1.
  • Number of green marbles is 2.

<h2>Explanation and Calculations:</h2>

So there are in total 10 marbles.

Two marbles can be chosen in ^{10}C_2 ways = 90/8

Now the favorable event is when one green marble and one orange marble  is chosen. The number of ways this can be done is ^{2}C_1 \times ^{2}C_1 = 4

The resultant probability is calculated by:

P(E) = \dfrac{Number \:of\: Favourable \:cases}{ Number\: of\: total \:cases}\\= \dfrac{4}{\frac{90}{2}}\\\\= \dfrac{8}{90}\\\\\approx 0.08889

Thus the needed probability is 0.08889 given by option C.
