A survey was done that asked people to indicate whether they preferred to swim in a pool or in an ocean. The results are shown i
n the two-way table.
If 609 people were surveyed, what is the relative frequency (rounded to the nearest hundredth) of a person over 30 years old who prefers to swim in the ocean?
hint: you will have to divide the part by the whole
Question 2 options:
.54
.30
.57
.09

Answer:
a) (x³ -x² +x +2) +2/(x+1)
b) (x² +2x -5) +6/(x+3)
Step-by-step explanation:
Polynomial long division is virtually identical to numerical long division, except that the quotient term does not require any guessing. It is simply the ratio of the leading terms of the dividend and divisor. As with numerical long division, the product of the quotient term and the divisor is subtracted from the dividend to form the new dividend for the next step.
The process stops when the dividend is of lower degree than the divisor.
In part (a), you need to make sure the dividend expression has all of the powers of x present. This means terms 0x³ and 0x² must be added as placeholders in the given dividend. They will become important as the work progresses.
