2. Use either a shift in demand OR a shift in supply (not both) to GRAPHICALLY represent each of the following situations. Also, label the graphs correctly and indicate the changes in equilibrium in each case.
a) The avocado market: Widely publicized studies on the health benefits of avocado consumption.
b) Crude oil market: Interruption of world supplies as a result of the war in the Middle East.
c) Orange Juice Market: Increased imports of orange juice from Brazil.
d) Hotel room occupancy in Mexico: Increased Corvid 19 infection rate in the USA and Canada, the largest source of tourists to Mexico.

Four separate graphs, please.

Movement restrictions imposed by various governments to mitigate the spread of COVID-19 pandemic in the form of social distancing and closure of national and international borders and airports has brought a number of business organisations to a standstill, leading to the decline in growth and market share, especially the hard hit tourism and hospitality industries. Assume that you are the manager of IDISAM Hotel LTD, which holds the largest market share in the hospitality industry, but now on the verge of collapsing due to COVID-19 pandemic. Required: Supporting your answers with specific examples and justifications, propose corporate or grand strategies that the company can use to deal with the situation at hand.

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?
