Step-by-step explanation:

x+5=0

x= -5

(R)=P(-5)

= -5^3+2*(-5)^2-13*(-5)+10

= -125+50+65+10

= 0

Step-by-step explanation:

what the other answer tries to say is that it proves that x = -5 is a 0 point of the function P(x).

and that means that (x + 5) is a factor.

because the factors of such a polynomial are the terms of x that would bring the whole expression to 0.

so, but now to the actual division :

x³ + 2x² - 13x + 10 ÷ x + 5 = x² - 3x + 2

- x³ + 5x²

-----------------

0 - 3x² - 13x

- - 3x² - 15x

------------------------

0 2x + 10

- 2x + 10

------------------------------

0 0

as the remainder is 0, this shows that (x + 5) is a factor.

Consider two people being randomly selected. (For simplicity, ignore leap years.)
inna [77]

Answer:

(a) = \frac{144}{133225} \\\\(b) = \frac{1}{365}

Step-by-step explanation:

Part (a) the probability that two people have a birthday on the 9th of any month.

Neglecting leap year, there are 365 days in a year.

There are 12 possible 9th in months that make a year calendar.

If two people have birthday on 9th; P(1st person) and P(2nd person).

=\frac{12}{365} X\frac{12}{365}  = \frac{144}{133225}

Part (b) the probability that two people have a birthday on the same day of the same month

P(2 people selected have birthday on the same day of same month) + P(2 people selected not having birthday on  same day of same month) = 1

P(2 people selected not having birthday on  same day of same month):

= \frac{365}{365} X \frac{364}{365} =\frac{364}{365}

P(2 people selected have birthday on the same day of same month) = 1-\frac{364}{365} \\\\= \frac{1}{365}
