Suppose that in order to save money, the Golden Eagles Nest dining area isconsidering limiting the number of cashiers to one even during peak hours, butbefore making that decision, wants to know how much congestion the reduction incashiers would cause. Suppose that the average transaction takes thirty (30)seconds, so the cashier can handle at most two (2) customers per minute. Supposethat during peak hours, an average of 2.5 students visit the dining area per minute;what percentage of days would the cashier be able to keep up on his/her/eir own?i.e. calculate P(X<= 2) and express your answer in decimal format rounded to twodecimal places.

A typical high school student consumes 67.5 pounds of sugar per year. As part of a new nutrition plan, each member of a track team plans to lower the sugar he or she consumes by at least 30% for the coming year. Assuming each track member had consumed sugar at the level of a typical high school student and will adhere to this plan for the coming year, what is the maximum number of pounds of sugar to be consumed by each track team member in the coming year? 44 47 54 66
Suppose that in order to save money, the Golden Eagles Nest dining area is considering limiting the number of cashiers to one even during peak hours, but before making that decision, wants to know how much congestion the reduction in cashiers would cause. Suppose that the average transaction takes thirty (30) seconds, so the cashier can handle at most two (2) customers per minute. Suppose that during peak hours, an average of 3.0 students visit the dining area per minute; what is the standard deviation of the distribution? Round your answer to two decimal places.
An editorial in The New York Times on Sunday, June 4, 2011 discussed the redesigned fuel economy stickers to be required on new cars starting in 2013. Consider a new midsize Ford Fusion S model. At $4-a-gallon gas, annual fuel costs would be about $2,200 for 15,000 miles driven. ... And that’s for a car with a rated mileage of 34.9 m.p.g. (actual highway mileage, as with all vehicles, is lower, in this case about 27 m.p.g.). Industry clearly needs to do better. Did the Times use the rated or the actual mileage in its computation? In Canada, some multi-lane highways have a speed limit of 110 km/hour. Convert this speed to miles per hour, so you'll know how fast you may drive in Canada.

Ron and Tim both work as landscapers during the summer months. Due to the heat, thescheduled start time is 7am. Typically though, the crew leader is late and most days they do notactually start work until 7:30 or 8am. Ron likes to catch a quick nap while he waits, however Timusually will pick up a broom or clean to pass the time. What time would his “compensabletime” begin for Ron and Tim (assume that 7:45 is the average start tim
You are the VP, Advertising for “Yo’ Mama” brand, a fashion label that caters to the young, trendy crowd with an urban, hip-hop image. While your customer base has traditionally been largely African-American, you have recognized a tremendous influx of Hispanic consumers into your market. You are preparing for next week’s annual budget meetings and you have decided to recommend an Hispanic-focused advertising campaign if the average monthly per store sales to Hispanic customers are at least the same as the average monthly per store sales to African-American customers in a sample of typical stores (sales data given below). Using an alpha of .05 and the 5-step hypothesis testing process, what will you recommend? Hint: Think about how many data points you actually have.
Suppose that with a certain phone company, an international long distance phone call from Canada to Brazil costs $0.90 for the first minute (up to and including 60 seconds), plus $0.50 for each additional minute or part of a minute. Note: "Part of a minute" means that if a new minute is started even just by one second, a full minute is charged. For example, a 5 min 1 sec phone call costs the same as a 5 min 50 sec phone call and the same as a 6 min O sec phone call. Suppose C (t) is the function that gives the cost of making a t minute long phone call. On a piece of paper, sketch a graph showing C (t) (with C on the y-axis and t on the a-axis). Then use your graph to evaluate each of the following: (Write DNE for undefined.) C (2.5) [ Select ] C (4) = [ Select ] lim C (t) [ Select ] 2+3.1 lim C (t) [ Select ] lim C (t) = [ Select ] lim C (t) = [ Select ]
A certain faculty printer is shared by staff and students. Suppose that the rate of generating requests to the printer by staff is twice that of students, but that the average time to print a student printout is the same as average time for a faculty printout. If the utilization of the printer by the students is 25%, the utilization of the printer by the faculty is 50%, the overall average service time is 1 minute, what is the average time the students spend waiting for their printout (time spend in system)?
