One model for the spread of a rumor is that the rate of spread is proportional to the product of the fraction y of the population who have heard the rumor and the fraction who have not heard the rumor (a) Write a differential equation that is satisfied by y. (Use & for the constant of proportionality ky(1 -y) (b) Solve the differential equation. Assume y(o) +(1-e or. By noon harthe to n has heard t. At hat time will 90% or the population have heard the run on be not round c) A small town has soo inhabitants. At 8 AM 120 people have heard a run in your calculation, Round the final answer to one decimal place.) 120333x hours after the beginning
