Answering the first Question i.e. 19.
For the given activity, every activity have tow parameters whose are
deadline - d
execution time - e
arrival time - a
For the activity,
Earliest time for the activity is = a + d
Latest time of the activity = a + e
= difference of the earliest stime - lastest time
= d - e
Y is defined as the time it takes to do an activity which is equal to the execution time - arrival time i.e a - e
X - Y = d - e - a + e = d - a
This is equal to the response time of the activity.
19. If X is the time difference between the earliest and latest times that an activity...
