Qand r are independent events. p(q) = 0.2; p(q and r) = 0.07. find p(r)

What point is the projection of q on a) r b) s c) t

The population of a small rural town in the year 2006 was 2,459. the population can be modeled by the function below, where f(x residents and t is the number of years elapsed since 2006. f(t) = 2,459(0.92)

Find the solution(s) to x^2-14+49=0
