Abusiness plan is centered around a circular area of distribution. the plan calls for the radius of the distribution to increase 50 miles per year. the investors have asked that the plan include a reference to the area of distribution based on the number of years in business. these functions model this plan: radius in y years: r(y) = 50y total area: a(r) = πr2; r in miles what is a(r( the total area in y years? a(r(y)) = 50πy2 a(r(y)) = 2,500πy2 a(r(y)) = 50πr2 a(r(y)) = 2,500πr2

According to an airline, flights on a certain route are on time 85% of the time. suppose 17 flights are randomly selected and the number of on-time flights is recorded.(a) explain why this is a binomial experiment. (b) determine the values of n and p (c) find and interpret the probability that exactly 12 flights are on time. (d) find and interpret the probability that fewer than 12 flights are on time (e) find and interpret the probability that at least 12 flights are on time (f) find and interpret the probability that between 10 and 12 flights, inclusive, are on timeidentify the statements that explain why this is a binomial experiment. select all that apply. a. the probability of success is the same for each trial of the experiment. b. the experiment is performed a fixed number of times. c. there are three mutually exclusive possibly outcomes, arriving on-time, arriving early, and arriving late. d. the experiment is performed until a desired number of successes is reached. e. the trials are independent. f. each trial depends on the previous trial. g. the probability of success is different for each trial of the experiment. h. there are two mutually exclusive outcomes, success or failure.
