2. 50. Furniture. A furniture manufacturing company manufactures dining-room tables and chairs. The relevant manufacturing data are given in the table below. 7 W s g Labor-Hours per Unit Maximum Labor-Hours Department Table Chair Available per Day Assembly 8. Finishing 120 1. $25 Profit per unit 062$ (A) How many tables and chairs should be manufactured each day to realize a maximum profit? What is the maxi- mum profit?
Suppose you are the marketing manager of a firm, and you plan to introduce a new product to the market. You have to estimate the first year net profit, which depends on several variables • Sales volume (in units) • Price per unit • Unit cost . Fixed costs Your net profit is net profit = sales volume x (price per unit-unit cost) - fixed cost The fixed cost is $120, 000, but other factors have some uncertainty. Based on your market research, there are equal chance that the market will be slow, ok, or hot. • Slow market the sales volume follows Poisson distribution with mean 50,000 units product, and the average price per unit is $11.00 ● Ok market the sales volume follows Poisson distribution with mean 75,000 units product, the average price per unit is $10.00 Hot market: the sales volume follows Poisson distribution with mean 100,000 units product, but the competition is severe so you expect the average price per unit is just $8.00 No matter what the market type is, your average unit…
Assuming equal effort (# of nets in the water has not changed and the fishing season dates have stayed the same) identify trends in the squid population you see in the data. Based on your textbook reading this week, speculate what processes or dynamics could produce the population trends seen in your data.
1. Suppose that you estimate a model of house prices to determine the impact of having beach frontage on the value of a house.14 You do some research, and you decide to use the size of the lot instead of the size of the house for a number of theoretical and data availability rea- sons. Your results (standard errors in parentheses) are: PRICE; = 40 + 35.0 LOT¡ – 2.0 AGE; + 10.0 BED; – 4.0 FIRE; (1.0) (5.0) (10.0) (4.0) (10) N = 30 R2 =.63 where: PRICE¡ =the price of the th house (in thousands of dollars) =the size of the lot of the th house (in thousands of square feet) = the age of the th house in years =the number of bedrooms in the th house =a qualitative/dummy variable for a fireplace (1 = yes for the th house) LOT; AGE; BED; FIRE; a. You expect the variables LOT and BED to have positive coefficients. Create and test the appropriate hypotheses to evaluate these expectations at the 5-percent level. b. You expect AGE to have a negative coefficient. Create and test the appropriate…
Can you please help me with this problem and the three parts that come along with it because i don't understand the problem and i just don't get it. Can you do this problem step by step and can you label the three parts as well.
3. (5.7.12) On June 2, 2010 USA Today reported a story from Bloomberg News that said that the total price tag for the project to build the new F-35 Joint Strike Fighter would be 65% higher than the original $232 billion estimate. The cost now is estimated to be $382 billion. The total cost of each plane would be $112.4 million, up 81% from the original $62 million. The cost to produce each plane would be $92.4 million, about 85% higher than the original estimate of $50 million. a. Check the arithmetic to see that the three percentage increases reported are correct. b. Can you explain how the project cost can have increased by just 65% when the overall total per plane increased by 81% and the construction cost alone increased by almost 85%?
3. The point guard of a basketball team has to make a decision about whether or not to shoot a three- point attempt or pass the ball to another player who will shoot a two-point shot. The point guard makes three-point shots 30 percent of the time, while his teammate makes the two-point shot 48 percent of the time. X; 3 0 P(x;) 0.30 0.70 X; 2 0 P(x;) 0.48 0.52 a. What is the expected value for each choice? b. Should he pass the ball or take the shot himself? Explain.
