Consider the following system:
Six trucks are used to haul coal from a mine to the rail road. There are two loaders and one weighing scale. After loading a truck immediately moves to the scale for weighing using FIFS policy. After weighing a truck begins a travel time and then returns to loader queue with the distribution of travel time as:
Travel time (Mins)
40
60
80
100
Probability
0.3
0.4
0.1
0.2
Further the distribution of loading time and weighing time are as:
Loading time (Mins)
5
10
15
Probability
0.5
0.3
0.2
Construct simulation table to trace the six trucks and:
(a) Compute average waiting time of loading
(b) Compute average time in system (loading and scaling times)
(c) Compute waiting probability for scaling
(d) Estimate the loader and scale utilization

I've been working on this for a few days and i just don't understand, it's due in a few hours. you.the direction of a vector is defined as the angle of the vector in relation to a horizontal line. as a standard, this angle is measured counterclockwise from the positive x-axis. the direction or angle of v in the diagram is α.part a: how can you use trigonometric ratios to calculate the direction α of a general vector v = < x, y> similar to the diagram? part bsuppose that vector v lies in quadrant ii, quadrant iii, or quadrant iv. how can you use trigonometric ratios to calculate the direction (i.e., angle) of the vector in each of these quadrants with respect to the positive x-axis? the angle between the vector and the positive x-axis will be greater than 90 degrees in each case.part cnow try a numerical problem. what is the direction of the vector w = < -1, 6 > ?
