- Recent data suggests that, as of 2013, the rate of growth predicted by Moore’s Law no longer holds. Growth has slowed to a doubling time of approximately three years. Find the new function that takes that longer doubling time into account.The Fast Track Ski Shoppe sells ski goggles during the four months of the ski season.Average demand follows: a. Calculate the deseasonalized sales and the seasonal index for each of the fourmonths.b. If next year’s demand is forecast at 1200 pairs of goggles, what will be the forecast sales for each month?Throughout the first semester of 2015, Macro Inc. sold plums in three deliveries as follows: 300 boxes of plums at $2.25 per box, 250 boxes at $1.90 per box and 400 boxes at $1.75 per box, respectively. Find the average price per box during the term in question. (Provide your answer to two decimal places)
- The snowboard industry has the following labour supply is ES = 150 + 10w and labour demand is ED = 350 – 10w, where E is the level of employment in 1,000s of workers and w is the hourly wage. If the labour market is competitive, then what is the equilibrium wage and employment? What is the unemployment rate? Let's pretend the government asks you to examine the impact of implementing a minimum hourly wage of $12. What would happen to the employment level? How many additional workers would want a job at the minimum wage? What is the unemployment rate? If the labour market is competitive, then what is the equilibrium wage and employment?

What is the unemployment rate?A manufacturing company had won a contract to supply 109200 units of a product to a customer.The production planing and control department of the company has estimated the production in the first week to be 8,000 units,but that by recruiting and training some extra staff,output will rise by 200 units each week . a. When would the company be able to complete the contract. B.If the recruitment of staff does not go as well as expected so that after six weeks ,weekly production remains constant at the level achieved in the sixth week.how long would it take to complete the contractAn editorial in the New York Times on Sunday June 4, 2011 dicussed the redesigned fuel economy stickers to be required on new cars starting in 2013. Consider a new idsize fuord fusion s model. At $4-a-gallon gas, annual fuel costs would be about $2,200 for 15,000 miles driven... And thats for a car with a rated mileage of 34.9m.p.g. actual highway mileage, as with all vehicles, is lower, in this case about 27m.p.g. Industry clearly needs to do better. Did the times use the rated or the actual mileage in its computation?
- The Company’s research department has provided the following estimates: A demand of 230 banquet attendees can be expected at a dinner plate price of $80 each. A demand of 370 banquet attendees can be expected at a dinner plate price of $45 each. Catering Service A has a fixed cost of $1,900 and a marginal cost of $30 for each plate. Catering Service B has a fixed cost of $3,000 and a marginal cost of $22 for each plate. Costs for both caterers include the food, drinks, plates, utensils, tablecloths, glasses, crew, and cleanup. Dinner plates will only be sold as an entire unit. To justify company resources and to ensure the event will benefit the charity, the CEO insists the tickets be sold for no less than $40. All profits will go toward a charity of the committee's choosing. Additional spontaneous donation to the charity will be accepted the night of the banquet. Studies estimate that 5% will give $5, 23% will give $20, 18% will give $50, 7% will give $100, and 2% will give $500.…When is the average cost per year minimum? (This time is frequently referred to as the replacement time for this piece of equipment.)A public utility intends to buy a turbine as part of an expansion plan and must now decide on thenumber of spare parts to order. One part, no. X135, can be purchased for $100 each. Carrying anddisposal costs are estimated to be 145 percent of the purchase price over the life of the turbine. Astockout would cost roughly $88,000 due to downtime, ordering, and “special purchase” factors.Historical records based on the performance of similar equipment operating under similar conditions suggest that demand for spare parts will tend to approximate a Poisson distribution with amean of 3.2 parts for the useful life of the turbine.a. What is the optimal number of spares to order?b. Carrying no spare parts would be the best strategy for what range of shortage cost?
- A company is keen on investing in expanding its market penetration in Africa opening an on-line shop to new potential African clients. For this reason, the company wants to understand the level of digital divide, measured by the total number of internet users in relation to total population, as a function of clients’ personal characteristics. Considering the following analysis based on a survey conducted in two main markets, Nigeria and Kenya, we have the following information to estimate the digital divide: Age: respondent’s age from 25 to 55 years old. Gender: 1 female, 0 male. Education level measured as years of schooling. Region: Kenya =1, Nigeria =0. As part of their work they have produced the following linear regression. How well does the model “describe/explain” the digital divide? How would you improve the model? Is the model statistically significant?A company is keen on investing in expanding its market penetration in Africa opening an on-line shop to new potential African clients.
