last two please answer

An electronics manufacturer makes remote control devices for interactive-cable-TV systems. The following assembly tasks must be performed on each device. Task Description Predecessors) Time (min) A Place circuit into circuit frame 0.50 B Solder circuit connections to central circuit control A 0.70 C Place circuit assembly in device frame B 0.40 D Attach circuit assembly to device framec 0.30 E Place and attach display to frame 10.30 F Place and attach keypad to frame 0.20 G Place and attach top body of device to frame EF 0.35 H Place and attach battery holder to frame 0.40 0 Place and attach bottom body of device to frame GH 0.60 Test device 10.30 Draw the precedence diagram for this problem then determine the following: a. What is the sum of the task times? 4.05 minutes b. What cycle time will slow the production of 200 units over a ten hour day? minutes What is the theoretical number of workstations needed? 2 Draw the precedence diagram for this problem, then determine the following: a. What is the sum of the task times? 4.05 minutes b. What cycle time will allow the production of 200 units over a ten-hour day? 3 minutes c. What is the theoretical number of workstations needed? 2 d. What is the actual number of stations? 2 e. Was there an opportunity to improve the balance of the line based on cycle time? Yes efficiency? 25 1:45:03.7% V If so, what is the new cycle time, Idle time and 1. Based on your answer toe. what is the total idle time over the 10 hour work day. In minutes? 653
