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

answer: there are 453.592 grams in a pound.

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.

the answer will be b x² +x-1
