The number of people arriving for treatment at an emergency room can be modeled by a Poisson process with a rate parameter of six per hour. a) What is the probability that exactly three arrivals occur during a particular hour? (Round your answer to three decimal places.)(b) What is the probability that at least three people arrive during a particular hour? (Round your answer to three decimal places.)(c) How many people do you expect to arrive during a 45-min period?

:i need some real : a store sells shirts to the public at one pricing scale and wholesale at another pricing scale. the tables below describe the cost, y, of x shirts. (after tables) how do the slopes of the lines created by each table compare? the slope of the public table is 3/4 of the slope of the wholesale table. the slope of the wholesale table is 3/4 of the slope of the public table. the slope of the public table is 12 times greater than the slope of the wholesale table. the slope of the wholesale table is 12 times greater than the slope of the public table.
