What are some technical challenges and questions that arise from the need to represent digital information in computers and transfer it between people and computational devices?

One subtask in the game is to roll the dice. explain why is roll the dice an abstraction.

Researchers measured the data speeds for a particular smartphone carrier at 50 airports. the highest speed measured was 78.1 mbps. the complete list of 50 data speeds has a mean of x overbarequals16.11 mbps and a standard deviation of sequals18.65 mbps. a. what is the difference between carrier's highest data speed and the mean of all 50 data speeds? b. how many standard deviations is that [the difference found in part (a)]? c. convert the carrier's highest data speed to a z score. d. if we consider data speeds that convert to z scores between minus2 and 2 to be neither significantly low nor significantly high, is the carrier's highest data speed significant? a. the difference is nothing mbps.

What are listed in the vertical columns across the top of the event editor? a. file names b. conditions c. check marks d. action types
