An advertising agency notices that approximately 1 in 50 potential buyers of a product sees a given magazine ad, and 1 in 9 sees a corresponding ad on television. one in 100 sees both. one in 3 actually purchases the product after seeing the ad, 1 in 10 without seeing it. what is the probability that a randomly selected potential customer will purchase the product? (round your answer to four decimal places.)

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct

7 is the median   7.875 is the mean
