Answer:

<em>3/40000</em>

Step-by-step explanation:

<em>Data:</em>

<em>Business 500 students</em>

<em>Laws 800 students</em>

<em>30 pairs of siblings, 1 in each school</em>

<em />

<em>It is required to calculate the probability that a random pair of siblings is chosen.</em>

<em />

<em>For this:</em>

<em>Business, of 500 students we have 30 siblings to choose one</em>

<em />

<em>30/500</em>

<em />

<em>Continue, choose the sibling's partner, Laws, of 800 only 1 is the sibling of the chosen in Business.</em>

<em />

<em>1/800</em>

<em />

<em>So we have:</em>

<em>(30/500) * (1/800) = 30/400000 = 3/40000</em>

<em />

<em>You can choose in reverse, first Laws and then Business, leaving:</em>

<em>(30/800) * (1/500)= 30/400000 = 3/40000</em>

<em />

<em>And it gives the same result: 3/40000</em>

Divide using synthetic division. ( x^4-12x^2-9)/(x+3)
Firdavs [7]

Answer:

x^3 - 3x^2 - 3x + 9 + (-36/(x+3))

OR

x^3 - 3x^2 - 3x + 9 - (36/(x+3))

Step-by-step explanation:

First set the divisor equal to 0:

x + 3 = 0

Subtract 3 from both sides

x = -3

This is what you'll divide the dividend by in synthetic division.

Take the coefficents of each term in the dividend. Do not forget the 0 placeholders:

x^4 + 0x^3 - 12x^2 + 0x -9

Coefficents: 1. 0.  -12. 0 -9.

Please see the image for the next steps.

The remainder is -36. Put the remainder over the divisor and add it to the polynomial (shown in image)

-36/(x+3)
