Assume six routes connect point A to point B. The probability that an accident appears in each of these routes and closes the entire route at any single day is 0.01. Accidents occur independently Assume that any closed route takes the entire day to be reopened, so each day can be considered as an independent trial. (a) What is the probability that all six routes close on one day.
(b) What is the probability that at least one route closes on a day

step-by-step explanation:

yes it represnts a functio, their are not 2 of the same numbers on the both sides

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

you can use a^2+ b^2=c^2
