On average, a customer spends 2 minutes waiting in line, 3 minutes placing the order, and 5 minutes completing the order before leaving the drive-through. How many customers on average are “in” the drive-through (i.e., from the time they enter to the time they exit the drive-through) on a typical day?

Utility is composed of the following components EXCEPT __________.

C&A Bakery serves 100 customers over the course of an 8-hour day. What is the flow rate of customers in this bakery per hour?

A restaurant promising a meal in two minutes or less attempts to cater to which part of the customer utility function?

A particular virus that infects E. coli does so by integrating its DNA into the bacterial DNA. How well this integration goes depends on the topology of the E. coli ‘s DNA. If the superhelical density (σ) of the E. coli DNA is greater than −0.045, the probability of integration is less than 20%. However, when σ is less than −0.06, this probability is >70%. Show your work.   The bacterial DNA isolated from an E. coli culture is found to have a length of 13,800 bp and an Lk of 1,222. a) Explain why σ is typically a negative number in cells. b) Calculate σ for this bacterial DNA. Show your work. c) Predict the likelihood that the virus will be able to integrate its DNA into the E. coli genome.
