PLEASE HEL(BRAINLIEST FOR RIGHT ANSWER) What is the rectangular form of r = 8 sin(θ)?

(x − 4)2 + y2 = 16
(x + 4)2 + y2 = 16
x2 + (y − 4)2 = 16
x2 + (y + 4)2 = 16

Four airplanes carrying a total of 400 passengersarrive at the detroit airport. the airplanes carry, respectively,50, 80, 110, and 160 passengers.a) one of the 400 passengers is selected uniformly at random.let x denote the number of passengers that were on theairplane carrying the randomly selected passenger. find var(x)for x as given in the problemb) one of the 4 airplane drivers is also selected uniformly atrandom. let y denote the number of passengers on the chosen driver’s airplane. find var(y) for y as given in the problem
