If y varies directly as x, and y is 48 when x is 6, which expression can be used to find the value of y when x is 2?

y = StartFraction 48 Over 6 EndFraction (2)

y = StartFraction 6 Over 48 EndFraction (2)

y = StartFraction (48) (6) Over 2 EndFraction

y = StartFraction 2 Over (48) (6) EndFraction

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
