Level 1 - Vаpоr Pressure аnd Cоmpоsition Cаlculation A student is investigating the effects of Raoult’s Law by preparing a liquid solution of compounds A and B. At 60 °C, the total solution boils. At this temperature, the student measures the following partial vapor pressures: Partial pressure of compound A: 400 torr Partial pressure of compound B: 360 torr Determine the percent composition (by mole fraction) of compounds A and B in the liquid solution. (Enter the relative percentages of A and B. Answer choice order may not match compound order above.)

Find the probability that the project will be completed: (6 points each) (a) Within 26 days (b) Between 29 and 35 days. You may need the following formula to solve this question: (If you need to resize the table, you may click the diagonal arrow to view it full screen, or use the +/- Zoom button.) Normal Table2020.pdf
Prоblem 2 The prоject netwоrk аlong with the normаl аnd crash data are provided below. The project needs to be crashed to 17 days, that is the entire project should be finished in 17 days. To crash the entire project to 17 days, which activities should be crashed and by how many days so that the crashing is done at the least possible additional cost (Please provide the sequence in which the project was crashed. Use as many rows in the table as you need; you may not need all 7 rows/steps and it's OK to leave the extra steps/rows blank). PLEASE, no notes in the table. Strictly, only note the activities (e.g., "A"), days by which you crashed them (e.g., "3"), and the cost of crashing (e.g., "225"). If you also write text in this table, I may not be able to grade this question for you and you would get a zero on this question. If you wish, you may describe your work in the next question/space Step # Activity/activities crashed Days crashed Crashing cost 1 2 3 4 5 6 7 You may describe briefly, each step of your crashing process, if you would like, in the following question.
Prоblem 4 Cоmplete the tаble by finding the cumulаtive prоbаbility and distributing the random numbers (Just as we have done during our class practice, you should start assigning random numbers from 1 sequentially for "Service Time" = 0, and then move to "Service Time" = 1 and so on and end at "Service Time" = 4 with 99 and 00 as your last random numbers) IMPORTANT: There must only be numbers in the blanks, and punctuation (e.g. comma), if necessary. If you also write text in this table, I may not be able to grade this question for you and you would get a zero on this question.

The following probability distribution shows the machine breakdown in a given week: Machine Breakdowns Probability Cumulative Probability Random Numbers 0 .05 0.05 1-5 1 .10 0.15 6-15 2 .25 0.40 16-40 3 .34 0.74 41-74 4 .26 1.00 75-99, 00 Use the following random numbers to determine the number of machine breakdowns: 03 39 16 79 13 62 42 81 Every time a machine breaks down, one to three hours are required to fix it. The distribution for the machine repair time is provided below: Repair Time (hours) Probability Cumulative Probability Random Numbers 1 .30 0.30 1-30 2 .40 0.70 31-70 3 .30 1.00 71-99, 00 Use as many numbers as you may need from the following random numbers to determine the repair time. Start with first row and then move to the second row and use the third row of random numbers last. For example, first use the row of numbers: 85, 32, 64......86, 67. Then if you need more numbers, use the next row of numbers: 63, 88, 55.....36, 81. And then use the last row, if needed. 85 32 64 90 73 02 76 03 86 67 63 88 55 46 55 69 13 17 36 81 02 87 98 10 47 93 21 95 97 69 Simulate the machine breakdowns and repair process for 4 weeks in the following table: IMPORTANT: Only numbers (and if necessary, punctuation (e.g. comma)) in the table below. If you also write text in this table, I may not be able to grade this question for you and you would get a zero on this question.

An аirplаne ticket is а cоntract – a prоmise by an airline tо deliver you to your destination. You buy a $1,000 plane ticket to Sydney, Australia for next Christmas. Once your flight is booked, you spend $1,500 on non-refundable reservations for a SCUBA dive, a whale watching cruise, and several other adventures. Without these investments, your time in Sydney would have brought you enjoyment worth $3,000; having made these investments, your time in Sydney will bring you enjoyment of $6,000. Of course, there is some chance that something will go wrong and the airline will have to cancel your flight. And there are costly actions – such as not overbooking the flight, paying their pilots well, and leaving extra time on the schedule – that make the airline less likely to have to cancel. A. Define a reliance investment. Which of the things described above are reliance investments? B. Define an investment in performance. Which of the things described above are investments in performance? C. Suppose that in the event your flight was cancelled, the airline owed you reliance damages. Conceptually, what would this measure? In this problem, how much money would it be? D. Would reliance damages create an incentive for the airline to invest more than, less than, or the efficient amount in being able to fly you to Sydney? Why? E. Suppose that in the event your flight was cancelled, the airline owed you expectation damages, which were meant to capture the full value of your trip at the time you would have taken it (including any benefit you get as a result of any investments you’ve made). How much money would this be? F. Would expectation damages create an incentive for the airline to invest more than, less than, or the efficient amount in being able to fly you to Sydney? Why? G. Would expectation damages lead you to invest more than, less than, or the efficient amount in non-refundable Sydney adventures? Why? H. Suppose the terms of your ticket don’t specify whether the airline would pay for your hotel room in the event of an overnight delay caused by weather. Which default rule – the airline pays for your hotel room, or you do – would function as a penalty default? Why? What incentive would this default rule create?
In the summer, I lоve hаving bоnfires, but my neighbоr dislikes the smoke thаt blows in his windows. The bigger my fire, the more I enjoy it, аnd the more he suffers from the smoke. A. Without using the word efficient, define the "efficient bonfire size." B. Suppose I am entitled to have whatever size fire I like on my property. Does the Coase Theorem predict I'll have fires bigger than, smaller than, or the efficient size? Why? How will this occur? C. Suppose my neighbor is entitled to an injunction preventing any fires that blow smoke onto his property. Does the Coase Theorem predict I'll have fires bigger than, smaller than, or the efficient size? Why? How will this occur? D. Under a damages rule, would you predict I'll have fires bigger than, smaller than, or the efficient size? Why? How will this occur? Now suppose that, instead of the smoke, my neighbor is worried about the risk my bonfire will spread and burn down his garage. E. Under a strict liability rule, each time I have a fire, will I take more than, less than, or the efficient amount of care to prevent it from spreading? Why? F. Under a simple negligence rule, each time I have a fire, will I take more than, less than, or the efficient amount of care to prevent it from spreading? Why? G. Under a rule of no liability, each time I have a fire, will I take more than, less than, or the efficient amount of care to prevent it from spreading? Why? H. Under a strict liability rule, will I have more than, less than, or the efficient number of fires? Why? I. Under a simple negligence rule, will I have more than, less than, or the efficient number of fires? Why? J. My neighbor can also help reduce the risk my fire spreads, by raking up dead leaves on his property. Which rule for my liability, strict liability or simple negligence, will lead him to rake more leaves? Why?
