Wld incorporated, a national data-collection agency, estimates that % of all customers at home warehouse stores (in the united states) own their own home. wld also estimates that % of all home warehouse customers have lived at their current address for less than five years, and that % of all home warehouse customers both own their own home and have lived at their current address for less than five years. using these estimates, what is the probability that a randomly selected home warehouse customer owns her own home or has lived at her current address for less than five years (or both)?

Our required probability is 0.62=62%.

Step-by-step explanation:

Since we have given that

Let A be the event that all customers at home warehouse stores own their own home.

Let B be the event that all customers at home warehouse have lived at their current address for less than 5 years.

P(A) = 54% = 0.54

P(B) = 34% = 0.34

P(A∪B) = 26% = 0.26

We need to find the probability that a randomly selected home warehouse customer owns her own home or has lived at her current address for less than five years.

So, P(A∪B) is given by

Hence, our required probability is 0.62=62%.

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
