(1 point) A culture of yeast grows at a rate proportional to its size. If the initial population is 80008000 cells and it doubles after 33 hours, answer the following questions.1. Write an expression for the number of yeast cells after tt hours.Answer: P(t)=P(t)= 2. Find the number of yeast cells after 77 hours.Answer: 3. Find the rate at which the population of yeast cells is increasing at 77 hours.Answer (in cells per hour):
An average of 40 cars per hour (interarrival times are exponentially distributed) are tempted to use the drive-in window at the Hot Dog King restaurant. If a total of more than 4 cars are in line (including the car at the window) a car will not enter the line. It takes an average of 4 minutes (exponentially distributed) to serve a car. (a) What is the average number of cars waiting for the drive-in window (not including a car at...

Cars arrive at a rate of 10 per hour in a single-server drive-in restaurant. Assume that the teller serves vehicles with a rate exponentially distributed with a mean of 4 minutes per car (ie, a rate of 1 car every 4 minutes). Answer the following questions: (a) What is the probability that the teller is idle? (b) What is the average number of cars waiting in line for the teller? (A car that is...

An assembly line can produce 90 units per hour. The line's hourly cost (total salaries of workers) is $4,248 an hour (the first 8 hours). Workers are guaranteed a minimum of 6 hours (i.e., they will be paid for 6 hours per day, even if they work less than 6 hours). There is a 50% premium for overtime (i.e., salary is increased 50% during overtime hours), however, productivity for overtime drops by 8% (i.e, the number of units produced per...
