Ecologists often use the number of reported sightings of a rare species of animal to estimate the remaining population size. Suppose that the number of reported sightings per week of blue whales follows a Poisson distribution with a mean of 3 per week. Find the probability that the time between consecutive sightings is between 1 and 2 weeks. Give your answer to 3 decimal places.

(a) the volume of the cone is 20/3 in3

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
