In fishery science, a cohort is the collection of fish that results from one annual reproduction. It is usually assumed that the number of fish N(t) still alive after t years is given by an exponential function. For Pacific halibut,
N(t) = N0e−0.2t,
where N0 is the initial size of the cohort. Approximate the____percentage of the original number still alive after 6 years.
N(t) = N0e−0.2t,
where N0 is the initial size of the cohort. Approximate the____percentage of the original number still alive after 6 years.
