Suppose the time it takes a barber to complete a haircuts is uniformly distributed between 5 and 17 minutes, inclusive. Let X = the time, in minutes, it takes a barber to complete a haircut. Then X ~ U (5, 17). Find the probability that a randomly selected barber needs at least seven minutes to complete the haircut, P(x > 7) (round to 4 decimal places)

And for this case we can use the cumulative distribution given by:

And if we use the complement rule and the before formula we have:

Step-by-step explanation:

For this problem we denote the random variable X as  the time, in minutes, it takes a barber to complete a haircut and the distribution for X is given by:

And we want to find the following probability:

And for this case we can use the cumulative distribution given by:

And if we use the complement rule and the before formula we have:

i dont get

y-1700=200(x+4)

step-by-step explanation:

200(x+4) is 200x + 800 she is saving 200 per week x is the weeks and the -1700 is. us that’s howmuch she already had
