In order to maximize profits or minimize losses, a competitive firm will produce at the point where MC = MR. Do you agree or disagree with this statement? Explain your answer and use at least 2 examples in your response.
In order to maximize profit, a firm that produces two goods that are related in consumption should chose the
levels of output at which:
total marginal revenue equals total marginal cost
total marginal revenue equals the marginal cost of each good
the marginal revenue of each good equals total marginal cost
marginal revenue equals marginal cost for each good
none of the above
1. In order to test the effectiveness of the debate of the candidates for the president, researchers randomly contacted 1000 people on the phone. An attempt was made to contact all 1000 one day before the debate and ask their voting intentions. Only 910 were actually reached by phone; 80 out of the 910 people refused to participate. One day after the debate, 810 of the 910 people were reached and again asked their voting intentions. In addition they were asked if they had seen the debate on television. The before-after change of the viewers and non-viewers were compared to conclude which candidate was more effective in the debate.What kind of experimental design is being used? Describe relevant potential extraneous variables in this experiment. Can this experiment design rule out these extraneous variables?

In order to simulate weightlessness for astronauts in training, they are flown in a vertical circle. If the passengers are to experience weightlessness, how fast should an airplane be moving at the top of a vertical circle with a radius of 2.50 km?
In our work and personal lives, we need to be able to identify and analyze effective verbal and nonverbal communication in various situations. In the same way that you would analyze a work or personal life communication situation, you will be asked to create a short presentation (using media choices below) about the nonverbal communication demonstrated in a series of photographs. In addition to identifying aspects of nonverbal communication, you will also need to show how these elements can affect communication both positive and negatively. Include your observations of how nonverbal elements that you see alter the direction of communication.
In order to sell a product at a profit the product must be priced higher than the total of what it costs you to build the unit, plus period expenses, and plus overhead.At the end of last year the broad cost leader Baldwin had an Elite product Bit. Use the Inquirer’s Production Analysis to find Bit’s production cost, (labor+materials). Exclude possible inventory carrying costs. Assume period expenses and overhead total 1/2 of their production cost. What is the minimum price the product could have been sold for to cover the unit cost, period expenses, and overhead?Select: 1$21.45$35.00$32.17$10.72Looking forward to next year, if Chester’s current cash balance is $17,334 (000) and cash flows from operations next period are unchanged from this period and Chester takes ONLY the following actions relating to cash flows from investing and financing activities:Issues 100 (000) shares of stock at the current stock priceIssues $200 (000) of long-term debtPays $40 (000) in dividendsWhich of the following activities will expose Chester to the most risk of needing an emergency loan?Select: 1Sells $5,000 (000) of their Long-term assetsPurchases assets at a cost of $15,000 (000)Liquidates the entire inventoryRetires $20,000 (000) in long-term debtA productivity index of 110% means that a company’s labor costs would have been 10% higher if it had not made production improvements. Assume that Digby had a productivity index of 112% and that Baldwin had a productivity index of 103%. Now refer to the Income Statements in the Annual Report for Digby and Baldwin. Using the labor costs shown in the Income Statements, how much more did Digby save in direct labor costs compared to Baldwin by having a higher productivity index?Select: 1$3,188$2,869$3,507$3,347From a marginal analysis perspective, what is the inventory carry cost for Andrews if the company carries one additional unit of Axe in inventory at the end?Select: 1$2.47$4.93$11.45$1.37Increasing the promotional budget for a product in order to increase awareness is not advisable in the short run under which of the following circumstances?Select: 1Demand in the segment is increasingAccessibility is less than 80%One or more competitor has increased priceProduction capacity is maxed out (200% plant utilization) and the company is stocking out of the productIn three years, assuming the competitive environment remains unchanged, how many units of Bell will Baldwin be selling in the Nano market segment?Select: 1603464687764According to information found on the production analysis page of the Inquirer, Chester sold 1128 units of Creak in the current year. Assuming that Creak maintains a constant market share, all the units of Creak are sold in the Nano market segment and the growth rate remains constant, how many years will it be before Creak will not be able to meet future demand unless the company adds production capacity? Exclude any existing inventory.Select: 14 year(s)3 year(s)1 year(s)2 year(s)Which description best fits Andrews? For clarity:- A differentiator competes through good designs, high awareness, and easy accessibility.- A cost leader competes on price by reducing costs and passing the savings to customers.- A broad player competes in all parts of the market.- A niche player competes in selected parts of the market.Which of these four statements best describes your company’s current strategy?Select: 1Andrews is a broad differentiatorAndrews is a broad cost leaderAndrews is a niche cost leaderAndrews is a niche differentiatorDemand is created through meeting customer buying criteria, credit terms, awareness (promotion) and accessibility (distribution). According to the Thrift segment’s customers, which of these products was the most competitive at the end of last year?Select: 1ArtBamDrumDaftWith the overall contribution margin of 34.1%, after direct costs this revenue will add $947,858 to the bottom line. For simplicity, assume that the demand increase and margins will remain at last year’s levels. How long will it take to achieve payback on the initial $2,000,000 TQM investment, rounded to the nearest month?Select: 125 monthsTQM investment will not have a significant financial impact9 months17 months
