- Consider two servers that are in a row so that the client is first served on server 1, from where the client then moves to server 2. On both servers, clients are served on a first-come, first-served basis (FIFO). Customer B arrives at the first server so that customer A is already being served there. B must therefore wait until A has been served to the end on server 1 and moves on to server 2. It is assumed that the service times of the customers on server 1 and 2 are exponentially distributed and independent, so that the average service time on server 1 is 4 ms and on server 2, respectively, 1 ms. After customer B, there will be no new customers. (Hint: Properties of the exponential distribution and the dynamics of Markov processes) a) What is the average remaining delay of customer A in the system? That is, how long does it take on average for client A to leave server 2 when client B has arrived? (Hint: Customer A's delay does not depend on customer B.) b) What is the average total…arrow_forwardD,E,F and G needed to be solved correctly in 10 minutes in the order to get positive feedbackarrow_forwardAt the imaginary university e/UT there are 101 students in their first year at M&CS. In their first year the students need to take k courses. To help them the students are registered for tutor groups. The following conditions hold: o Every student is involved in each course. o Each student is involved in one or more tutor groups. o Each tutor group is involved in one or more courses. o Every student in a course is involved in exactly two tutor groups. o Each pair of students is involved in exactly one tutor group. What is k? (Prove your answer.) (Hint: count the total number of registrations for tutor groups.)arrow_forward
- Let N= {1, 2, 3, 4, .} be the set of natural numbers and S= (1, 4, 9, 16, ...} be the set of squares of the natural numbers. Then N - S, since we have the one-to-one correspondence 1 + 1, 2 + 4, 3 + 9, 4 + 16, ... n+ n?. (This example is interesting, since it shows that an infinite set can be equivalent to a proper subset of itself.) Show that each of the following pairs of sets are equivalent by carefully describing a one-to-one correspondence between the sets. Complete parts (a) through (c) below. (a) The whole numbers and natural numbers, W = {0, 1, 2, 3, ..} and N= {1, 2, 3, 4, ...} Which of the following describes a one-to-one correspondence between the two sets? O A. For each element in W, there is an element in N that is double that element. O B. For each element in w. there is an element in N that is 1 areater than double that element.arrow_forwardTo avoid collisions with invasive species of aliens, new imperial regulations allow only positive integer space jumps parallel to the three space axes defined in the Jedi council's booklet of rules and regulations.
