An ornithologist is studying a population of female cardinals as it changes each year. They are assuming the following things about this bird population: 1st year cardinals Does not lay eggs 70% survive to 2nd year 2nd year cardinals Has 2 female offspring each 40% survive to 3rd year 3rd year cardinals Has 1 female offspring each None survive to 4th year [90 Suppose right now the distribution of cardinals in each age group is 60 70 After 1 year, how many cardinals will be in each age group? [Round answers to the nearest whole number.] 1st year: 2nd year: 3rd year: Graded Anony Comments: No Comments How many birds will be in each age group after 3 years? [Round answers to the nearest whole number.] 1st year: 2nd year: 3rd year: x1 If the vector b = x2 represents the distribution of birds, where x1 is the number in X3 the 1st year, x2 is the number in the 2nd year and x3 is the number in the 3rd year, find the matrix A so that Ab is the distribution of birds after 1 year. A =
