An airline charges the following baggage fees: $25 for the first bag and $35 for the second. suppose 54% of passengers have no checked luggage, 34% have one piece of checked luggage and 12% have two pieces. we suppose a negligible portion of people check more than two bags.
(a) build a probability model, compute the average revenue per passenger, and compute the
corresponding standard deviation.
(b) about how much revenue should the airline expect for a flight of 120 passengers? with what
standard deviation? note any assumptions you make and if you think they are justified.

Part a what is the area of triangle i? show your calculation. part b triangles i and ii are congruent (of the same size and shape). what is the total area of triangles i and ii? show your calculation. part c what is the area of rectangle i? show your calculation. part d what is the area of rectangle ii? show your calculation. part e rectangles i and iii have the same size and shape. what is the total area of rectangles i and iii? show your calculation. part f what is the total area of all the rectangles? show your calculation. part g what areas do you need to know to find the surface area of the prism? part h what is the surface area of the prism? show your calculation. part i read this statement: “if you multiply the area of one rectangle in the figure by 3, you’ll get the total area of the rectangles.” is this statement true or false? why? part j read this statement: “if you multiply the area of one triangle in the figure by 2, you’ll get the total area of the triangles.” is this statement true or false? why?

When drawing a trend line for a series of data on a scatter plot, which of the following is true? a. there should be an equal number of data points on either side of the trend line. b. all the data points should lie on one side of the trend line. c. the trend line should not intersect any data point on the plot. d. the trend line must connect each data point on the plot.
