As you drive to school, suppose the probability that you have to stop at a traffic light at a specific intersection on your way is 0.75. In a given week you approach this intersection 10 times. Assume that each time you approach the intersection the probability that you have to stop for the red light is the same and is independent of any other approach. What is the probability that you will have to stop for a red light at this intersection at least half of the time in a given week of driving to school

the two may have that, even a breakdown is probably offered

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

i think it is 18
