You are waiting at the bus stop for a bus, which arrives every X minutes, where X is a random variable with an exponential PDF, and a mean of 30 minutes. You have been already waiting for 10 minutes. What is the probability that you will wait for 20 more minutes, given that you have already been waiting for 10 minutes?

1. A bus leaves every 25 minutes. Let X be the number of minutes you have to wait at a bus stop, which is written as X U[0,25). (a) Using the definition formula,E[X] = **fx(r)dt, show that the mean of the length of time that you have to wait until catching a bus is 12.5. (20 pts) Note: fx(x) denotes the PDF of X. 1fx(x)dx, show that the mean (c) Using...

The bus arrives every 15 minutes starting at 8:00am and leaves
immediately. You arrive at the bus stop with a uniform distribution
between 8:05am and 8:30am and can be described as . Given that the bus arrival
time and the time that you arrive at the bus stop are independent,
what is the PDF of your
wait time?

The bus arrives every 15 minutes starting at 8:00am and leaves immediately. You arrive at the bus stop with a uniform distribution between 8:05am and 8:30am. Given that the bus arrival time and the time that you arrive at the bus stop are independent, what is the PDF of your wait time? Graph the PDF of your wait time.

A bus arrives at a stop every 15 minutes exactly, in a very consistent way, very easily drawn. A passenger is not aware of the schedule, and arrives randomly at the stop. Let X represent the number of minutes they wait for the bus to arrive. What type of random variable is X, if the passenger arrives completely randomly at the stop? Circle the correct answer: Discrete Normal Uniform Sketch a picture for X based upon your answer to part...

Currently the bus runs every 7 minutes during the day. Let X represent the amount of time Sofia waits for the bus, assuming she arrives at the bus stop at a random time and the bus is running on schedule. (That is, the amount of time Sofia waits is uniformly distributed.) Find the following probabilities (use 2 decimal places for all answers): (a) The probability Sofia waits at most 2 minute(s) = (b) The probability Sofia waits less than 2...

Part 3: The Uniform Distribution
Suppose that you need to take a bus that comes every 30 minutes.
Assume that the amount of time you have to wait for this bus has a
uniform distribution between 0 and 30 minutes. The probability
density curve for this distribution is given below.
1) Is waiting time a discrete or continuous random variable?
2) What is the area of this entire rectangle?
3) What numbers are represented by a, b and c (note:...

What is the value if the previous dividend was Do= $2.00 and investors expect dividends to grow at a constant annual rate of (1) -5%, (2) 0%, (3) 5%, or (4) 10%? b. Using data from Part a, what would the Gordon (constant growth) model value be if the required rate...

just need some help with number 5 Suppose that the time at which a businessperson leaves for lunch (in hours after noon) is a continuous random variable X with probability density function f(x) = c(1-x)2 for 0 < x < 1, where c is the appropriate constant, and f(x) = 0 otherwise. 1.Determine the value of c for this to be a legitimate pdf. 2.Sketch this pdf. (Hand-drawn is fine.) 3.Determine the probability that this businessperson leaves for lunch before...
