Denote owl and wood rat populations in a particular area at time k by xk LK Rk where k is the time in months, Lk is the number of owls in the area studied, and R is the number (in thousands) of wood rats in the area studied. Suppose Lk+ 1 = (0.2)Lk + (0.6)Rk and Rk+1=(-0.1)Lk + (0.9)Rk. Determine the evolution of this system. (Give a formula for xk.) Does the owl population grow or decline? Does the wood rat population grow or decline?

An advertising firm is hired to promote a new television show for 3 weeks before its debut and 2 weeks afterward. After t weeks of advertisement campaign, it is found that P(t) percent of the viewing public is aware of the show, where P(t) = (59t/0.7t^2+16) + 6 a. What is the average percentage of the viewing public is aware of the show during the 5 weeks of advertising campaign? (Hint: P(0) is already in the unit of percent) b. At what time during the first 5 weeks of the campaign is the percentage of viewers is the same as the average percentage found in part (a)? (Hint: use algebra or graph to solve the problem

Assume that the entire sample has 2 positive observations and 6 negatives observations. Variable X1: at the left branch has 2 positive observations and 4 negatives observations;at the right branch has 6 positive observations and 6 negatives observations. What is the information gain or reduction in uncertainty of X1 using the Gini index? (round to two decimal spaces) I am getting negative value -1.37 for this question.But information gain should be positive.
