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.

Consider the following statements: #include #include class temporary { private: string description; double first; double second; public: temporary(string = "", double = 0.0, double = 0.0); void set(string, double, double); double manipulate(); void get(string& , double& , double& ); void setdescription(string); void setfirst(double); void setsecond(double); }; write the definition of the member function set() so that the instance variables are set according to the parameters. write the definition of the constructor so that it initializes the instance variables using the function set() write the definition of the member function manipulate() that returns a decimal number (double) as follows: if the value of description is "rectangle", it returns first * second if the value of description is "circle" it returns the area of a circle with radius first if the value of description is "cylinder" it returns the volume of a cylinder with radius first and height second. hint: the volume of a cylinder is simply the area of the circle at the base times the height. if the value of description is "sphere" it returns the volume of the sphere with radius first. otherwise it returns -1.0;
