Now, what is the most efficient schedulability test for determining whether the task set in Table 1 is schedulable under preemptive RM?Determine whether there is a feasible schedule for the following NONPREEMPTABLE task sets. T1 (periodic): c1 = 2, d1 = p1 = 8 T2 (sporadic): c2 = 1, d2 = 6, p2 = 7 T3 (sporadic): c3 = 1, d3 = p3 = 10 please type out the answers
- A personnel director wishes to compare the effectiveness of two methods of train- ing industrial employees to perform a certain assembly operation. Employees are to be divided into two equal groups: the first receiving training method 1 and the sec- ond training method 2. Each will perform the assembly operation, and the length of assembly time will be recorded. It is expected that the assembly times for both groups will have a range of approximately 8 minutes. For the estimate of the difference in mean times to assemble to be correct to within minute with a probability equal to .95, how many workers must be included in each training group? 16c3d JPG Fi DOTable 1. 4 processes arriving shown in Operating System Scheduling PDF for Shortest Job Next, non- preemptive Process Arrival Times Execution Times Service Times sequence Wait Times calculations PO 0 12 P1 21 9 P2 41 6 P3 6 3 Total wait time = ? Here the 4 processes of the PDF are repeated in Table 1, with arrival times changed to 0, 2, 4, and 6 respectively. Also, the execution times are changed to 12, 9, 6, and 3. You will be asked to fill table 1 with the numbers like the service times (when is each process serviced), the sequence of executions of these 4 processes in part (a) and part (b) below. Also, you will compute the total wait time. Note for FCFS, it is 1, 2, 3, 4 for P0, P1, P2, and P3; • for the SJN or Shortest Job Next with non-preemptive, PO is #1, P1 may not be #2; for SRT, or shortest remaining time, the preemptive version of SJN, PO is #1, but after 2 time units when P1 comes, P1 kicks out PO since its execution time is 4 < 9- 2 = 7; and P1 may be preempted by P2 later…I need an explanation when 2 schedules are conflict equivalent, with examples of conflict equivalent schedules.And examples where 2 schedules are not conflict equivalent. Please, be simple. Here is the Theorem, but I need someone to explain it better and use real example.

Suppose we represent the activities by the variables A, B, C, D, and E, where the domain of each variable is {1, 2, 3, 4} and the constraints are A > D, D > E, C ̸= A, C > E, C ̸= D, B ≥ A, B ̸= C, and C ̸= D + 1. Show how backtracking solves this problem. To do this, you should draw the searchtree generated to find all answers. Indicate clearly the valid schedule(s) aka solution(s).Make sure you choose a reasonable variable (and value) ordering if needed, and mention them explicitly.Calculate average wait time for the following situation.
