Mag Tech assembles Blu-ray players from four major components arranged as follows: B The components can be purchased from three different vendors, who have supplied the following reliability data: Vendor Component 1 2 3 0.83 0.92 0.83 B 0.93 0.85 0.91 0.94 0.88 0.90 D 0.93 0.80 0.93 (a) If MagTech has decided to use only one vendor to supply all four components, which vendor should be selected? (Round answers to 4 decimal places, e.g. 2.7500.) Vendor 1 Vendor 2 Vendor 3 + should be selected. Calculate the reliability of systems A and B shown below. System A Round your answer to 4 decimal places. 0.91 0.91 System B Round your answer to 4 decimal places. 0.95 0.95 0.95 Which system is more reliable. A or B? Calculate the total cost of systems A and B if it costs $600 for each 85% component, $1,200 for each 91% reliable component, $2.000 for each 95% reliable component, and $7,000 to replace a failed system. (Don't round your intermediate answers, round your final Total cost of system A$ answer to whole number.) Total cost of system B $ to whole number.) .(Don't round your intermediate answers, round your final answer Based on lowest cost, which system would you choose, A or B? e Textbook and Media Calculate the reliability of systems C and D shown below. System C round your answer to 4 decimal places. 0.85 0.85 0.95 0.95 0.95 System D round your answer to 4 decimal places. 0.85 0.85 0.85 0.85 0.85 0.85 Which system is more reliable, C or D? Calculate the total cost of systems C and D if it costs $600 for each 85% component, $1,200 for each 91% reliable component, $2,000 for each 95% reliable component, and $7,000 to replace a failed system. ,(Don't round your intermediate answers, round Total cost of system C$ your final answer to whole number.)
