Suppose you’re building a vacation cottage up in the Rocky Mountains and you are concerned about the depth at which a new water line should be buried to avoid freezing during the cold winter weather. The soil there is dry and homogenous with a thermal diffusivity of 0.02 ft2/hr and a thermal conductivity of0.48 Btu/ ft hr °F . Suppose the initial temperature is 45 °F everywhere. At t=0, a very strong cold front moves in and the ambient temperature drops to –15 °F, and remains there for 48 hrs. How deep should the water line be so that the soil around the pipe does not fall below 30 °F during this period? Also, what is the heat flux at that depth at t=48 hrs?

Suppose you’re developing an office building for a business that will eventually occupy the space themselves. In this project, you’re acting as a fee developer (meaning you will put no equity into the project and your compensation will come as a fee paid by the client). The project will take 4 years to complete. You’ll receive an up-front fee of $250,000 when you start the project, and a completion bonus of $150,000 when the project is delivered to the client....

Your round-the-world vacation ran over budget. But you’re in luck. You just received an offer to transfer your $15,000 balance from your current credit card, which charges an annual rate of 24 percent, to a new credit card charging 18 percent. How much faster could you pay off the loan by making your planned monthly payments of $500 with the new card? Note: assume monthly compounding.

If you’re like some college students, you are always worried about having enough money. Suppose that you decide to become an Uber driver, and you offer rides to students on weekends. For a fee, you will drive them to parties and pick them up at the end of the night. Your marginal cost per ride is $10. To keep things simple, assume you are the only person in your town providing this service; that is, you’re a monopolist. On any...

According to a poll of adults about 41% work during their summer vacation. Suppose that this claim about the population proportion is true. Now if we take a sample of 75 adults, and find the sample proportion [^(p)] of adults who work during summer vacation. What is the expected value of sample proportion [^(p)]? Tries 0/5 What is the standard deviation of sample proportion [^(p)]? Tries 0/5 The shape of the sampling distribution of sample proportion [^(p)] will be roughly...

You’re playing pool and you line up a shot on the 3 ball. You want the 3 ball to be deflected by an angle of (Theta)3 = 25(Degrees) at a velocity v3 = 1.3 m/s so that it will make it into a side pocket. What initial velocity must you give the cue ball in order to make this shot and what will be the velocity and angle of the cue ball following the collision? Recall that the mass of...

Suppose you run an accounting firm and you're concerned about gender discrimination in the hiring process. The hiring process at your firm consists of two stages: review of resumes and then an in-person interview. Imagine that for a particular position your firm gets 120 resumes, 40 of which are from women. Your company will select 20 resumes for the in-person interview. If very few women are selected for the interview stage, it might be due to random chance or it...
