help please with these two questions

Littlefeld Labs has a bottleneck process with a capacity of handling 12 jobs per day. The demand rate is now 10 jobs per day. If Littlefield maintains a stable WIP level of having 125 units in the factory, what is the average flow time for customer jobs accepted by Littlefield? (Hint: simply apply the Little's Law.) O 12.5 hours O 9.4 days 09.4 hours 12,5 days Littleheld Labs has three stations to process blood testing jobs. Fall out the following table on your scratch paper If needed. Note that additional machines have been installed and the bottleneck mury have been shifted to a different place Number of Station Mean Raw Processing Time Parallel Machines Capacity (jobs per Bottleneck Yes or Nol day! Installed 81 5 hours #2 1.5+0.5-2 hours 2. #3 1.83 hours It demand rate is 9.6 jobs per day, what is the capacity utilization at the bottleneck? OS 40% 100% SOX Littlefield Labs processes blood tesing jobs and its first Station takes care of Sample Preparation (Step 1). It takes, on average, S hours to prepare a sample as the raw processing time. Station 1 currently has a capacity utilization of 50%. Assume the variability factor V - 1 for moderate variability from both the demand side and the process side. What is the expected Waiting Time for jobs to stay in the queue in front of Station 1? 5 hours 25 hours 10 hours 75 hours
