Air-USA has a policy of booking as many as 25 persons on an airplane that can seat only 23. (Past studies have revealed that only 85% of the booked passengers actually arrive for the flight.)

Find the probability that if Air-USA books 25 persons, not enough seats will be available.
prob =
(round to 4 decimal places)

Is this probability low enough so that overbooking is not a real concern for passengers if you define unusual as 5% or less?
yes, it is low enough not to be a concern
no, it is not low enough to not be a concern

What about defining unusual as 10% or less?
yes, it is low enough not to be a concern
no, it is not low enough to not be a concern

It takes a total of 6 hours to fill up an inground backyard pool using a standard house. a function can represent this situation to represent the amount of water in the pool until it is full a function of time the hose is running. determine the domain for the function

Which of the statements about the graph of the function y = 2x are true? check all of the boxes that apply. the domain is all real numbers x because the exponent of 2 can be any real number when the x-values increases by 1 unit, the y-value multiplies by 2. the y-intercept is (0, 1). the graph never goes below the x-axis because powers of 2 are never negative. the range is all real numbers.

Martha has a deck of cards. she has lost some of the cards, and now the deck only contains nine spades, eleven diamonds, eight clubs, and twelve hearts. martha predicts that whenever she draws a card from the deck without looking, she will draw a club one-fifth of the time. which activity would best allow martha to test her prediction? a. randomly draw a card from the box and see if it is a club. b. randomly draw a card. then, continue to draw another card until all eight clubs are drawn. c. randomly draw and replace a card 120 times. then, observe how close to 30 times a club is drawn. d. randomly draw and replace a card 100 times. then, observe how close to 20 times a club is drawn.
