Since Kristine has been a long-time loyal customer, Kristine is able to place a rush order at $30 ($15 premium in addition to the regular price of $15) per pound in late morning and have it delivered by the local market provider within an hour from the order time. Kristine is considering this option, because, by late morning, she knows for sure what the demand will be for the day. What is the probability that the size of the rush order is at least 20 pounds?

I need help with 3 and 4.John Milton and two of his colleagues are considering opening a law office in New York City that would make inexpensive legal services available to those who could not otherwise afford these services. The intent is to provide easy access for their clients by having the office open 360 days per year, 16 hours each day from 7:00 a.m. to 11:00 p.m. The office would be staffed by a lawyer, paralegal, legal secretary, and clerk-receptionist for each of the two 8-hour shifts. In order to determine the feasibility of the project, John hired a marketing consultant to assist with market projections. The results of this study show that if the firm spends $500,000 on advertising the first year, the number of new clients expected each day would have the following probability distribution: Number of New Clients per Day Probability 20 0.10 30 0.30 55 0.40 85 0.20 John and his associates believe these numbers are reasonable and are prepared to spend the $500,000 on advertising.

- Which of these methods to pay for college will rashad need to pay backThe college graduates of 2000 could hardly have asked for better luck. The unemployment rate dropped to 4.1 % in May 2000- roughly, the lowest level in a generation- and employers were literally scrambling for new hires. Starting salaries rose, many graduating seniors had numerous job offers, and some firms even offered $10,000- $20,000 bonuses to students who signed the dotted line. Three years later, the job market for the Class of 2003 was rather different. U.S. economic growth had slowed to a crawl, and then to a halt. Companies that had stocked up on recent college grads in the tighter labour markets of 1998-2000 found themselves with more than they knew what to do with in 2002 and 2003. They were not eager to hire more. Bonuses and other “perks” disappeared; job offers became scarcer. With the unemployment rate around 6% in May and June of 2003, the job market was far from the worst ever. But it was nothing like the glory days of 2000.
