A plane averages 1,200 miles in 2 hours. How many hours will it take to travel 3,300 miles? (Don't answer if you do not know it, please!!!)

Line u passes through points (-52, -18) and (-29, 53). line v passes through points (90, 33) and (19, 56). are line u and line v parallel or perpendicular?

Solve for the equation x. 2x + 22 = 4(x + 3)

Nielsen media research wants to estimate the mean amount of time (in minutes) that full- time college students spend watching television each weekday. find the sample size necessary to estimate the mean with a 15-minute margin of error. assume that a 95% confidence level is desired. also assume that the population standard deviation is known to be 112.2 minutes.
