The lengths of a professor's classes has a continuous uniform distribution between 50.0 min and 52.0 min. If one such class is randomly selected, find the probability that the class length is more than 50.5 min. P(X > 50.5) =  (Report answer accurate to 2 decimal places.)

A bus comes by every 13 minutes. The times from when a person arives at the busstop until the bus arrives follows a Uniform distribution from 0 to 13 minutes. A person arrives at the bus stop at a randomly selected time. Round to 4 decimal places where possible. The mean of this distribution is  The standard deviation is  The probability that the person will wait more than 6 minutes is  Suppose that the person has already been waiting for 0.3 minutes. Find the probability that the person's total waiting time will be between 1.1 and 2.3 minutes  42% of all customers wait at least how long for the train?  minut

Today, the waves are crashing onto the beach every 4.2 seconds. The times from when a person arrives at the shoreline until a crashing wave is observed follows a Uniform distribution from 0 to 4.2 seconds. Round to 4 decimal places where possible. a. The mean of this distribution is b. The standard deviation is C. The probability that it will take longer than 2.14 seconds for the wave to crash onto the beach after the person arrives is P(x > 2.14) = %3D

The duration of a professor's class has a continuous uniform distribution between 50.0 minutes and 52.0 minutes. If one class is randomly selected, find the probability that the professor's class duration is between 50.4 and 51.8 minutes.P(50.4<X<51.8)

The mean amount of time it takes a kidney stone to pass is 14 days and the standard deviation is 6 days. Suppose that one individual is randomly chosen. Let X = time to pass the kidney stone. Round all answers to 4 decimal places where possible. a. What is the distribution of X? X~ N( b. Find the probability that a randomly selected person with a kidney stone will take longer than 17 days to pass it. c. Find the minimum number for the upper quarter of the time to pass a kidney stone. days.

The lengths of a professor's classes has a continuous uniform distribution between 50.0 min and 52.0 min. If one such class is randomly selected, find the probability that the class length is between 51.4 and 51.8 min.P(51.4 < X < 51.8) =   Will you show your work please

please show me the step

The lengths of a professor's classes has a continuous uniform distribution between 50.0 min and 52.0 min. If one such class is randomly selected, find the probability that the class length is between 51.1 and 51.6 min. Round the answer to 3 decimal places.P(51.1 < X < 51.6) =

Business Weekly conducted a survey of graduates from 30 top MBA programs. On the basis of the survey, assume the mean annual salary for graduates 10 years after graduation is 156000 dollars. Assume the standard deviation is 36000 dollars.Enter each answer as a number between 0 and 1 accurate to 4 decimal places. Find the probability that salary of a randomly selcted single graduate is at least 154000 dollars.P(X > 154000) =
