Suppose users share a 1 Mbps link. Also suppose each user requires100

kbps when transmitting, but each user transmits only 10 percent

ofthe time.

(See the discussion Packet Switching Versus Circuit Switching

inSection 1.3).

A. When circuit switching is used, how many users can

besupported?

B. For the remainder of this problem, suppose packetswitching is

used.

Find the probability that a given user is transmitting.

C. (Suppose that there are 50 users. Find the probability that

atany given

time exactly n users are transmitting simultaneously (Hint: use

thebinomial

distribution).

D. Find the probability that there are 11 or more

userstransmitting

simultaneously. (Hint: use the central limit theorem.)

E. Solve D for 20 or more users.

This first part of the film shows the early history of motion pictures. how accurate do you think the portrayal of the early motion picture industry is? why? is historical accuracy important in films and theatre productions? explain. in the scene where don is going to the party (starting at time code 14: 51), we see a street scene as he first rides with cosmo and then with kathy. what aspects did the filmmaker include to make the scene look and feel like don, cosmo, and kathy are riding in a car on a street? think about elements such as scenery, sound, props, lighting, and so on. a "talkie" picture is shown starting around time code 21: 15. how does the audience in the film react to the "talkie"? what influence do audiences have on film and theatre performances? how do film and theatre actors influence audiences? in the musical scene with cosmo (starting at time code 27: 00), how does the actor use props? what is the result? do you think the use of props effectively fulfilled the artistic vision for this musical number? why or why not?

1. technician a says horsepower information can be used by consumers to compare the power of different automobile engines. technician b says that manufacturers will often list the horsepower output of their engines in the online service information. who is right?
