An x-method chart shows the product a c at the top of x and b at the bottom of x. below the chart is the expression a x squared + b x + c
consider the trinomial x2 – 9x + 18.

which pair of numbers has a product of ac and a sum of b?

what is the factored form of the trinomial?

On her way to work, mrs. larsen gets a green light at a certain traffic light only 30% of the time. she wants to find the probability that she will get a green light at this traffic light all five mornings that she travels to work next week. use the following randomly generated list of 200 five-digit numbers to answer the questions and find the probability. select the digits you will use to represent a favorable outcome. how many favorable outcomes are on this list? what are they? given this simulation, what is the probability that mrs. larsen will get a green light at this traffic light all five mornings next week?
