The accountant for a business that sells stuffed animals has provided some data about the costs associated with the production of different quantities of unicorns. Unicorns Produced Associated costs (in thousands of units) (in thousands of dollars) 1.96 15.6 3.63 11.98 6.18 6.99 11.65 5-35 13-79 7-76 15.03 15.44 a. Determine the quadratic line of best fit for this set of data. You will need to use quadratic regression in your calculator. f(a) = 2+4.570 0.256 x+ 24.507 (Please round each value to three decimal places, and then use the rounded versions of the numbers in the rest of the calculations.) b. How many unicorns should the company produce in order to minimize their costs? Numberunicorns (Round to nearest unicorn. Pay attention to the units!) c. How much would it cost the company tO produce that amount of unicorns from (b)? Number dollars (Round to nearest dollar. Pay attention to the units!) d. How much would it cost the company to produce 5000 stuffed unicorns? Number dollars (Round to nearest dollar. Pay attention to the units!) e. How many stuffed unicorns should be produced to cause the costs to be equal to $10,000? unicorns or Number unicorns Number (Round to nearest unicorn. Put the smaller value first, then the larger one. Pay attention to the units!)
