question 3 of 9
drag the tiles to the correct boxes to complete the pairs.
doug is analyzing the daily profits from the past month for three of his restaurant franchises. he has calculated the mean and sta
deviation of the data, in dollars, as shown below.
location a
location b
location c
mean = 6.127.85 mean = 6,296.07 mean = 6,191.28
sd = 413.51 sd = 440.67 sd = 330.83
match each restaurant franchise location with the correct description.
location a
location c
location b
for which location does 95% of the data
lie between $5,529.62 and $6,852.94
(2 sd from the mean)?
for which store does 6806 of the data

Aparticular telephone number is used to receive both voice calls and fax messages. suppose that 25% of the incoming calls involve fax messages, and consider a sample of 25 incoming calls. (a) what is the expected number of calls among the 25 that involve a fax message?

Using the figure below, select the two pairs of alternate interior angles.a: point 1 and point 4 b : point 2 and point 3 c: point 6 and point 6d: point 5 and point 7

Acaterer knows he will need 60, 50, 80, 40 and 50 dinner napkins on five successive evenings. he can purchase new napkins initially at 25 cents each, after which he can have dirty napkins laundered by a fast one-day laundry service (i.e., dirty napkins given at the end of the day will be ready for use the following day) at 15 cents each, or by a slow two-day service at 8 cents each or both. the caterer wants to know how many napkins he should purchase initially and how many dirty napkins should be laundered by fast and slow service on each of the days in order to minimize his total costs. formulate the caterer’s problem as a linear program as follows (you must state any assumptions you make): a. define all variables clearly. how many are there? b. write out the constraints that must be satisfied, briefly explaining each. (do not simplify.) write out the objective function to be minimized. (do not simplify.)
