The time to failure, t, in hours, of a machine is often exponentially distributed with a probability density function f(t) = k e^(-kt), 0 to infinity, where k= 1/a and a is the average amount of time that will pass before a failure occurs. suppose that the average amount of time that will pass before a failure occurs is 80 hr. what is the probability that a failure will occur in 55 hr or less?

Create a question with this scenario you could ask that could be answered only by graphing or using logarithm. david estimated he had about 20 fish in his pond. a year later, there were about 1.5 times as many fish. the year after that, the number of fish increased by a factor of 1.5 again. the number of fish is modeled by f(x)=20(1.5)^x.
