Nautica's bus schedule arrived at 8:20 am. Use the actual arrive times below to build an experimental probability model for future bus arrival times. Use three possible outcomes: late, early, and on time. Use the model to predict how many times the bus is most likely to be late in the next 5 days. Round your answer to the nearest whole number.

step-by-step explanation:

answer: the first graph

step-by-step explanation:

hello! just here for points! though i wish i knew!

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
