Your local hotel has a dining room which has the capacity to seat 140 guests. It is opened for breakfast and lunch seven days a week and fully expects to be at capacity at these times. During January 2021, management has forecast the seat turnover for breakfast will be 3 times and for lunch 2 times, with the average bill to be $28 for breakfast and $58 for lunch. Beverage revenue is usually 12 per cent of the breakfast revenue and 28 per cent of the lunch revenue.  

Calculate budgeted total revenue of food and beverage for the 31 days of January 2021. Express the answer as a daily food and beverage outcome and also a monthly figure.

While investigating a group of defective solar arrays, taken from the Mohammed Bin Rashid Al Maktoum Solar Park in Dubai, you notice three main classifications of defects. 27% of defects are related to a cell’s semiconductor material bandgap, 51% are related to impact damage, and 22% are age-related in nature. Over the study period, 3 instances of material bandgap defects and 5 occurrences of age-related defects are recorded. What is the most probable number of recorded defects related to impact damage?

Note: This problem is related to discrete probability distribution ( I think multinomial distribution should be used)

Betsy Birdsong, an interior designer, has made plans to definitely retire in three years. She has begun to downsize her business and is moving out of the 2,000 square foot commercial condominium she owns in a prestigious business park. Betsy does not wish to sell at this time, so she has decided to offer the condominium as a lease-purchase option. While she hasn't decided on a purchase price, she is adamant about the lease term:   a three-year lease with a two-year option (for the first two years only).  

What is your opinion as to why she would require such a lease term?

Suppose you pick 50 clovers from the grass in Washington square park. Some clovers are four-leaf clovers but most have only three leaves. Suppose clovers develop their leaves inde- pendently of each other and there is some probability p that they will develop into a four-leaf clover.

Calculate the probability that you get two or fewer four-leaf clovers, for each of p = 0.1, 0.05, 0.01. For each value of p, do the calculation in three ways: the exact calculation, the Poisson ap- proximation, and the Normal approximation (with the histogram correction.) Comment on your results – which approximation is better when?

In paper chromtography, what is the nature of the attractions between the stationary phase (cellulose) and the moving phase (hydrochloric acid/water/acetone) and the species ( Zn2+, Co2+, Cu2+, Cd2+ , Fe3+, and Ni2+ in two unknown solutions)  being separated, in particular what affects the Rf values and how?

Note: Filter paper (Whatman #1) serves as the stationary phase, and the mobile phase consists of a mixture of acetone and 6 M hydrochloric acid. A single spot of the mixture to be analyzed is applied near one edge of a sheet of filter paper. A spot of solution containing each of the cations that might be in the unknown mixture is also placed near the edge of the same sheet for comparison. The treated strip is then placed in a covered jar or beaker (which acts as a developing chamber) containing a shallow layer of the solvent mixture (see Figure 3). Since filter paper is very permeable to the solvent, the solvent begins to rise up the strip by capillary action. The various spots on the developed chromatogram will be highlighted by treatment with several chemical reagents to enhance their color. The reagents to be used are ammonia, dimethylglyoxime (DMG), and 8–hydroxyquinoline (oxine)

In paper chromotography, what form are the metals ( Zn2+, Co2+, Cu2+, Cd2+ , Fe3+, and Ni2+) ions likely to exist in the moving phase (water/hydrochloric acid/acetone) and what groups in the structure of the stationary phase (cellulose) are interacting with the moving ions in solution?

10.1Document for Analysis: Poor Persuasive Request Inviting Speaker to Discuss Seven Cardinal Sins in Food Service

(L.O. 1–3)

The following letter from a program chair strives to persuade a well-known chef to make a presentation before a local restaurant association. But the letter is not very persuasive. How could this message be more persuasive? What reader benefits could it offer? What arguments could be made to overcome resistance? How should a persuasive message conclude?

Your Task Analyze the following invitation and list its weaknesses, and write a revision.

Dear Ms. Watkins:

We know you are a very busy hospitality professional as chef at the Beverly Hills Hotel, but we would like you to make a presentation to the San Francisco chapter of the National Restaurant Association. I was asked to write you since I am program chair.

I heard that you made a really good presentation at your local chapter in Los Angeles recently. I think you gave a talk called “Avoiding the Seven Cardinal Sins in Food Service” or something like that. Whatever it was, I'm sure we would like to hear the same or a similar presentation. All restaurant operators are interested in doing what we can to avoid potential problems involving discrimination, safety at work, how we hire people, etc. As you well know, operating a fast-paced restaurant is frustrating—even on a good day. We are all in a gigantic rush from opening the door early in the morning to shutting it again after the last customer has gone. It's a rat race and easy to fall into the trap with food service faults that push a big operation into trouble.

Enclosed please find a list of questions that our members listed. We would like you to talk in the neighborhood of 45 minutes. Our June 10 meeting will be in the Oak Room of the Westin St. Francis Hotel in San Francisco and dinner begins at 7 p.m.

How can we get you to come to San Francisco? We can only offer you an honorarium of $200, but we would pay for any travel expenses. You can expect a large crowd of restaurateurs who are known for hooting and hollering when they hear good stuff! As you can see, we are a rather informal group. Hope you can join us!

Sincerely,
