Consider a geographical area divided (for mobile phone coverage purposes) into 36 hexagonal cells, without gaps or overlaps between them. each cell has a radius of 2 km. the reuse factor is 5. there are 350 channels in total.
i) what is the total area covered?
ii) what is the number of channels per cell?
iii) what is the maximum number of concurrent calls that can be handled?
iv) would the answers to (i), (ii) or (iii) change if the radius of each cell was 1 km and there were 144 cells in total?

Take a critical look at three gui applications you have used—for example, a spreadsheet, a word-processing program, and a game. describe how well each conforms to the gui design guidelines listed in this chapter.

Develop the program incrementally: a) start by reading and displaying each line of the input file to make sure you are reading the data set correctly. b) use the split string method to extract information from each line into a list. print the list to prove that this step is working correctly. d) convert the exam scores to type int and calculate the student’s average. display those items to prove this step is working correctly. e) create a tuple containing the six items for each student (name, exam scores, exam mean). display the tuples to prove this step is working correctly. (optionally, you may want to have the exam scores in a list so your tuple is (name, scores_list, f) append each tuple to a list. display the list to prove this step is working correctly. g) use the sort list method to re-order the tuples in the list. display the list to prove this step is working correctly. h) use a for statement to display the contents of the list as a table (with appropriate formatting). i) use a for statement to calculate the average of all scores on exam #1, then display the results. note that you could have calculated this average within the first loop, but we are explicitly requiring you to do this calculation by looping though your list of tuples. j) add the logic to calculate the average of all scores on exam #2, then display the results.
