Epidemics. The use of mathematical methods to study the spread of contagious diseases goes back at least to some work by Daniel Bernoulli in
Suppose that a given population can be divided into two parts: those who have a given disease and can infect others, and those who do not have it but are susceptible. Let

- PROBLEM NUMBER 2Which amount of time is greater for the average person? The total time spent on his/her cell phone in a year’s time, or the total time spent waiting in line when shopping in a lifetime?Consider it to be 2 separate problems just as in problem 1 and arrive at your conclusion. You need to make assumptions, conversions, and math calculations to arrive at your answer. You will not be graded on the accuracy of your assumptions. You will be graded on the process at arriving at your answers, the correct conversions once you make your assumptions, and your logic/thought process in arriving at both answers. If you choose to research data for this project, that is fine but there is no need to site your references.arrow_forwardPlacement Test Practice Problem #17arrow_forwardProblem 2: Luxury Cruise Lines has a fleet of ships that travel to Alaska repeatedly every summer. A considerable amount of advertising is done each winter to help generate enough passengers for the summer. With the coming of the new winter season, a decision needs to be made about how much advertising to do this year. Amount of 225 400 350 275 450 advertising ($1,000s) Sales 16 21 17 23 (thousands of passengers) 1. How many thousands of passengers would be generated if Luxury Cruise spends $300,000 on advertising? 2. Estimate the amount of advertising needed to target a booking of 22,000 passengers. 3. Is the regression model a good model? Wwhy? 20arrow_forward
- Please show detailed step-by-step explanation and solution for each question (problems 4,5, and 6).arrow_forwardIs there any way I could see an explanation for question 2?arrow_forwardQuestion 7. Shandy is a popular drink for young people in England. It is a mixture of beer and lemonade. In one pub, the owner likes to serve the mixture with 60% lemonade, 40% beer. He tells the bartender to prepare a large pitcher of shandy using 6 pints of lemonade and 4 pints of beer. The absent-minded bartender gets it backward. He mixes 4 pints of lemonade and 6 pints of beer. The owner fixes this by adding more lemonade. How many pints of lemonade does he add? Show your work.arrow_forward
