The IEOR advisor at ESS (Engineering Student Services) meets very few students in the early morning. Assume now there are 3 IEOR students in ESS, one meeting with the advisor and the other 2 are waiting in line. At the moment the student currently meeting with the advisor leaves, a 4th student comes in. Let W be the waiting time of the 4th student until he/she starts meeting with the advisor. Compute the PDF and CDF of W, assuming the service times for each student are i. i.d. with density f(x) = x^xe-, c > 0, A > 0.

What is the y intercept of f(x)=(1/2)^x?

Why is causation so much more difficult to prove than correlation?

In may you used 400 kilowatt-hours of energy for electricity. a. calculate the total electrical energy use in joules. b. calculate your average power use in watts. c. assume that your power supplier generates electricity by burning oil. note that 1 liter of oil releases 12 million joules of energy. how much oil is needed to generate the electricity you use? give your answer in both liters and gallons. a. the total electrical energy use was nothing _ joules. (type an integer or a decimal.) b. the average power use is nothing _ watts. (round to the nearest whole number as needed.) c. to generate the electricity you used, nothing _ l is needed. (round to the nearest whole number as needed.) to generate the electricity you used, nothing _ gal is needed. (round to two decimal places as needed.)
