In analyzing the runway proposal, the board has decided to use a 10-year time horizon. the county's hurdle rate for capital projects is 12 percent. the county board of representatives believes that if the county conducts a promotional effort costing $20,000 per year, the proposed long runway will result in substantially greater economic development than was projected originally. however, the board is uncertain about the actual increase in county tax revenue that will result. required: suppose the board builds the long runway and conducts the promotional campaign. what would the increase in the county's annual tax revenue need to be in order for the proposed runway's internal rate of return to equal the county's hurdle rate of 12 percent? (round your final answers to the nearest dollar.)

(c) compare the results of parts (a) and (b). in general, how do you think the mode, median, and mean are affected when each data value in a set is multiplied by the same constant? multiplying each data value by the same constant c results in the mode, median, and mean increasing by a factor of c. multiplying each data value by the same constant c results in the mode, median, and mean remaining the same. multiplying each data value by the same constant c results in the mode, median, and mean decreasing by a factor of c. there is no distinct pattern when each data value is multiplied by the same constant. (d) suppose you have information about average heights of a random sample of airline passengers. the mode is 65 inches, the median is 72 inches, and the mean is 65 inches. to convert the data into centimeters, multiply each data value by 2.54. what are the values of the mode, median, and mean in centimeters? (enter your answers to two decimal places.) mode cm median cm mean cm in this problem, we explore the effect on the mean, median, and mode of multiplying each data value by the same number. consider the following data set 7, 7, 8, 11, 15. (a) compute the mode, median, and mean. (enter your answers to one (1) decimal places.) mean value = median = mode = (b) multiply 3 to each of the data values. compute the mode, median, and mean. (enter your answers to one (1) decimal places.) mean value = median = mode = --
