The probability that a telephony call will last t minutes can be approximated as - probability that call lasts less than t minutes = 1 - e-t/a where e = euler’s constant (2.71828) and a = average call duration using the above probability function, write a program that a. takes the average call duration (a) from the user, b. then accepts the call duration to find the probability for (t) and c. then calculates and prints the probability that a call lasts less than t. the program should repeat the sequence of operations a to c until the user enters a value of 0 for either variable a or t in the steps a or b above

It is not a good idea in a cover letter to mention another person whom the employer knows.

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?

Assume that there is a 4% rate of disk drive failure in a year. a. if all your computer data is stored on a hard disk drive with a copy stored on a second hard disk drive, what is the probability that during a year, you can avoid catastrophe with at least one working drive? b. if copies of all your computer data are stored on three independent hard disk drives, what is the probability that during a year, you can avoid catastrophe with at least one working drive?
