Companies in the u.s. car rental market vary greatly in terms of the size of the fleet, the number of locations, and annual revenue. in 2011 hertz had 320,000 cars in service and annual revenue of approximately $4.2 billion. the following data show the number of cars in service (1000s) and the annual revenue ($ millions) for six smaller car rental companies (auto rental news website, august 7, 2012). excel file: data14-09.xls if required, enter negative values as negative numbers. a. select a scatter diagram with the number of cars in service as the independent variable. b. what does the scatter diagram developed in part (a) indicate about the relationship between the two variables? c. use the least squares method to develop the estimated regression equation (to 3 decimals). ŷ = + x d. for every additional car placed in service, estimate how much annual revenue will change. by $ e. fox rent a car has 11,000 cars in service. use the estimated regression equation developed in part (c) to predict annual revenue for fox rent a car. round your answer to nearest whole value. $ million hide feedback partially correct

You have been solicited to conduct a performance evaluation for a public organization that has been corrupted over issues of personnel embezzling funds. before actually conducting the evaluation, you—the evaluator—need to know certain specifics to conduct a thorough evaluation. compose a proposal that describes what type of evaluation will be conducted. in the proposal, explain the type of public organization. describe some of the main services, products, and activities the organization provides to the public. describe the size of the problem, who is affected by the problem, how long the problem has been in existence, and how long the evaluation will take. also, describe what the evaluation will assess with respect to organizational leadership. finally, what outcomes do you propose the evaluation will to achieve for the organization?

For example, the upper right cell shows that if expresso advertises and beantown doesn't advertise, expresso will make a profit of $15 million, and beantown will make a profit of $2 million. assume this is a simultaneous game and that expresso and beantown are both profit-maximizing firms. if expresso decides to advertise, it will earn a profit of $ million if beantown advertises and a profit of $ million if beantown does not advertise. if expresso decides not to advertise, it will earn a profit of $ million if beantown advertises and a profit of $ million if beantown does not advertise. if beantown advertises, expresso makes a higher profit if it chooses . if beantown doesn't advertise, expresso makes a higher profit if it chooses . suppose that both firms start off not advertising. if the firms act independently, what strategies will they end up choosing? expresso will choose to advertise and beantown will choose not to advertise. expresso will choose not to advertise and beantown will choose to advertise. both firms will choose to advertise. both firms will choose not to advertise.
