Mathematics

Using the probability concept, the correct statement is:

B. P(hibiscus|red) = P(hibiscus).

<h3>What is a probability?</h3>

A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.

For item a, the probabilities are:

  • P(yellow|rose) = 45/105 = 0.4286.
  • P(yellow) = 135/315 = 0.4286.

Same probabilities, hence the statement that they are different is false.

For item b, the probabilities are:

  • P(hibiscus|red) = 80/120 = 2/3.
  • P(hibiscus) = 210/315 = 2/3.

Equal, hence this is the correct statement.

Answer:

The Product Sum method of factoring we use on trinomials (ax2+bx+c) with the value of a=1. This is the method that is probably used the most.

example: x2+7x+12 The product is the a value times the c value. In this case 12.

The sum is the b value. In this case 7.

Find the two numbers that multiply to 12 (the product) andadd to 7 (the sum). +4 and +3

These are your two factors. In your two binomials put the x in front and the factors in the back. (x+4)(x+3)

This is your factored expression. To check FOIL back out.

Why does this work???

example:

x2-4x-12

p= -12

s= -4 factors are -6 and +2

so factored answer is (x-6)(x+2)

example:

I'm thinking of a number that could be solved by x2+10x+16=0. What could the number be?

p=16

s=10 factors are +8 and +2

(x+8)(x+2)=0

so either x+8=0 or x+2=0 so either x= -8 or -2 is the

number.
