pter 8. As we saw in Problem Set 2, on a Tnursday, decided thnat she would like to hnave a dini olleagues and was wondering If Saturday was a feasible day to have the party or not. She wanted to get an idea of how many hours of work she would need to do to make a fancy dinner ready by 6 PM on Saturday. She decided to create a project network based on the activities she thought were essential for doing this. We had helped her to identify the critical path by creating a project network and activity schedule. Now, Jeanie realizes that she has another project that needs to be completed by Saturday and wonders if she can "outsource" some of her activities by paying someone else to do them, since she only has a total of 6 hours available now instead of her original 12 hours of availability. Her normal costs and crashing costs along with the crashing time are given in the table below. She wants to minimize her costs, so running a crashing LP model is her best option. Time Normal Crashing Crash Activity Description Immediate (hours) Cost Time Cost Predecessor Ti Ci Ti Ci' JA Choosing dishes/recipes 2 200 1.5 300 Inviting and confırming # of people IB 12 200 1 300 Making ingredient list JA 1 100 500 D Making shopping list B, C 100 200 E Going for shopping 2 200 lo 300 IF Making the meal IE 500 lo 1500 G Setting the Table IF 0.5 50 lo 100

Phoenix is a hub for a large airline. Suppose that on a particular day, 8,000 passengers arrived in Phoenix on this airline. Phoenix was the final destination for 1,600 of these passengers. The others were all connecting to flights to other cities. On this particular day, several inbound flights were late, and 410 connecting passengers missed their connecting flight and were delayed in Phoenix. Of the 410 who were delayed, 85 were delayed overnight and had to spend the night in Phoenix. Consider the chance experiment of choosing a passenger at random from these 8,000 passengers. Calculate the following probabilities. (Round your answers to three decimal places.) (a) Calculate the probability that the selected passenger had Phoenix as a final destination. (b) Calculate the probability that the selected passenger did not have Phoenix as a final destination. (c) Calculate the probability that the selected passenger was connecting and missed the connecting flight. (d) Calculate the…

Suppose Gabe, an elementary school student, has just finished dinner with his mother, Judy. Eyeing the nearby cookie jar, Gabe asks his mother if he can have a cookie for dessert. She tells Gabe that she needs to check his backpack to make sure that he finished his homework. Gabe cannot remember where he left his backpack, but he knows for sure that he did not complete his homework and will not be allowed to eat a cookie. Gabe believes his only option is to quickly steal a cookie while his mother is out of the room. Judy then leaves the room to look for Gabe's backpack. Assume that Judy could return at any time in the next 60 seconds with equal probability. For the first 20 seconds, Gabe sheepishly wonders if he will get caught trying to grab a nearby cookie. After waiting and not seeing his mother, Gabe decides that he needs a cookie and begins to take one from the jar. Assuming it takes Gabe 30 seconds to grab a cookie from the jar and devour it without a trace, what is the…

A large bakery has many different products for sale. Suppose that 200 come in between 6am and 10am. Of the 200 customers 140 order donuts, 100 order cinnamon rolls, and 80 order both. Make a Venn Diagram to model the situation.
