. A hotel’s reservation center receives 180 calls on average from 9:00 AM – 10:00 AM, and the number of calls in that hour can be modeled by a Poisson random variable. (a) (8 pts) Find the probability that more than one call come in the one-minute period 9:26 AM – 9:27 AM. (b) (8 pts) Find the probability that the first call after 9:00 AM actually comes in after 9:02 AM.

The lifts at Purgatory open at 9 am (t=0) and close at 4 pm (t=7). On a certain run, the minimum depth of snow for safe skiing is 40 cm. Purgatory wants to keep the run open from 9 am to 4 pm, but also maintain the illusion of natural snow. So, they will run the snow making machine at the top of each hour, but run it the minimum length of time necessary to maintain a depth of snow...

A species of fish was added to a lake. The population size P (t) of this species can be modeled by the following exponential function, where t is the number of years from the time the species was added to the lake.P (t) =1000/(1+9e^0.42t) Find the initial population size of the species and the population size after 9 years. Round your answer to the nearest whole number as necessary. Initial population size is : Population size after 9 years is:
