 Let L = be the Leslie matrix for an animal population with 3 age groups. On average, how many female offspring do females in the second age group produce?
 Let L = be the Leslie matrix for an animal population with 3 age groups. Suppose that currently there are 100 females in the first age group, 60 in the second age group and 50 in the third age group. How many females will be in the first age group in the next time period? (Hint x1 = Lx0)
 Let L = be the Leslie matrix for a population, and let the initial population vector be x0 = . Find the number of individuals in each age class after three years?
