Airline passengers arrive randomly and independently at the passenger-screening facility at a major international airport. the mean arrival rate is 10 passengers per minutes. compute the following probabilities. p(x = 4) p(x > 11)

For each proportion find the unknown number x 1/5/8=×/15

Solve each quadratic equation by factoring and using the zero product property. 10x + 6 = -2x^2 -2
