A certain community consists of 1700 people, and one individual has a particularly contagious strain of influenza. Assuming the community has not had vaccination shots and are all susceptible, the spread of the disease in the community is modeled by 1700 1 + 1699 -0.35 where A is the number of people who have contracted the flu after t days. (a) How many people have contracted the flu after 14 days? Round your answer to the nearest whole number. people...

3. Aflu epidemic hits a college community, beginning with 10 cases on day t=0. The rate of growth of the epidemic (i.e. number of new cases per day) is given by the following function: r(0) = 30er where "p" is the number of days since the epidemic began. a. Find the average number of flu cases (Av) in the first 12 days (t=12). b. Find a formula for the total number of cases of flu, N(t), in the first "t"...

Suppose a student carrying a cold virus returns to an isolated college campus of 2000 students. Determine a differential equation for the number of people x(t) who have rate at which the disease spreads is proportional to the number of interactions between the number o students who have the cold and the number of students who have not yet been exposed to it....

Part A - SIR model for the spread of disease Overview. This part of the assignment uses a mix of theory and data to estimate the contact number c=b/k of an epidemic and hence to estimate the infection-spreading parameter b. The point is that once you know the value of b for a certain disease and population, you can use it in your model the next time there is an cpidemic, thus cnabling you to make predictions about the demand...
