I don’t remember how I get the answer to this. I have the answer key though. Please help, I have a test in an hour
mrs_skeptik [129]

Answer:

  f(x) = (x -2)(x -1+3i)(x -1-3i)

Step-by-step explanation:

You can use synthetic division to find the remaining quadratic factor in the cubic. Then any of the usual means of solving the quadratic will help you find its linear factors.

In the attached, I show the synthetic division, the factoring to real numbers, and the solution that finds the complex linear factors by completing the square.

Of course, you know that for zeros a, b, and c, the linear factors are ...

  f(x) = (x -a)(x -b)(x -c)

Here, we have a=2, b=1-3i, c=1+3i.

  f(x) = (x -2)(x -1+3i)(x -1-3i)

There are 6 orange marbles, 2 red marbles, 3 white marbles, and 4 green marbles in a bag. Once a marble is drawn, it IS replaced
professor190 [17]

The probability of selecting two orange marbles with replacement is 36/169.

Data;

  • Orange= 6
  • Red = 2
  • Green = 4

<h3>Probability with replacement</h3>

Since after each draw, the orange marble is replaced.

The total number of marbles in the bag is

6+3+4 = 13

And the number of orange marbles is 6.

For the first selection, the probability of selecting one orange is

P = \frac{6}{13}

After drawn and replaced, the probability of selecting another marble is

P = \frac{6}{13}

And the probability of selecting two orange marbles with replacement is

P = \frac{6}{13} * \frac{6}{13} = \frac{36}{169}

The probability of selecting two orange marbles with replacement is 36/169.
