In a cellular network, the total number of channels per cell is seven, among which two are reserved exclusively for handoff calls. Assume that both new and handoff call arrivals follow a Poisson process. The mean arrival rate of new calls and handoff calls are 1.5 calls/minute and 0.3 calls/minute, respectively. The channel holding time is exponentially distributed, with mean equal to 2 minutes. Calculate the blocking probabilities of new calls and handoff calls.

Q22. In a computer network a virus is spreading from machine to machine. Each week, the proportion of uninfected computers that remain uninfected is 0.75 with the rest becoming infected. Meanwhile, 0.45 of the computers that are infected are restored and become uninfected with the rest remaining infected. Suppose 0.80 of the network is currently uninfected. A b B Using the probabilities and states given, what proportion of the network will be infected the next week? (Enter numerical value only. Round the percentage to 3 decimal places)
You are an investor who receives daily price quotes for a stock. The span of a stock's price on a given day is the number of consecutive days, from the given day going backwards, on which its price was less than or equal to its price on the day we are considering. Thus, the Stock Span Problem is as follows: Given a series of daily price quotes for a stock, find the span of the stock on each day of the series. Assume you are given seven daily stock quotes: 3, 10, 4, 7, 9, 6, and 8. Assume further that these stock quotes are stored in the array quotes. Show a step-by-step, manual desk-check execution of the algorithm below showing the values of all variables and arrays for each step in each cycle of each loop, as demonstrated in clase Algorithm: A Simple Stock Span Algorithm SimpleStockSpan (quotes) → spans Input: quotes, an array with n stock price quotes Output: spans, an array with n stock price spans 2 3 4 5 6 7 8 10 11 spans CreateArray (n) ← for i0 to n do k 1 span_end FALSE while…

A computer store maintains a maximal inventory of 30 fax machines (units). On average,one unit is sold per day, but some days experience a burst of customers. A marketingsurvey suggests that customer inter-arrival times are iid exponentially distributed withrate 1 per day. When inventory drops down to 5 units on-hand, an order of 20 units isplaced to the supplier, and the order arrives in 5 to 10 days, uniformly distributed.Unsatisfied customers check back with the store and wait for the order to arrive(backordering case). Keep in mind that another order is placed immediately upon orderarrival, should the inventory level fall below the reorder level after satisfying allbackorders.a. Develop an Arena model of the computer store, and simulate it for 2 years ofdaily (9:00 AM to 5:00 PM) operation.
