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.

Ap practice - performance task response the ap create performance task asks you to write about an abstraction that you developed and wrote into your code. most of the time that means identifying a function or procedure you wrote to "manage complexity" in your program. here is the actual prompt from the create performance task: 2d. capture and paste a program code segment that contains an abstraction you developed individually on your own (marked with a rectangle). this abstraction must integrate mathematical and logical concepts. explain how your abstraction manage the complexity of your program. (must not exceed 200 words) below is a segment of code from an "under the sea" program with a rectangle drawn around a portion of the code identifying an abstraction. imagine that you wrote this and are composing an ap response about how this abstraction manages complexity. (note: ignore the requirement that the abstraction integrate "mathematical and logical concepts" for this practice response. just write about managing complexity). explain how the abstraction marked with the rectangle in the code above manage complexity of this program. write your response here submit

Freya realizes she does not have enough in her bank account to use the debit card. she decides to use a credit card instead. which questions should freya answer before using a credit card? check all that apply. can i pay at least the minimum payment each month? can i make payments on time and avoid late fees? will i have to take out a loan? how much in finance charges can i afford to pay? should i talk to a consumer credit counseling service?

Lucas put a lot of thought into the design for his company's new white paper. he made sure to include repeating design elements such as color schemes and decorative images. his goal was to a.add symmetry b.create a unified publication c.provide consistency d.save money
