Determine for the following code how many pages are transferred between disk and main memory, assuming each page has 2000 words, the active memory set size is 1000 (i. e., at any time no more than 1000 pages may be in main memory), and the replacement strategy is lru (the least recently used page is always replaced); also assume that all two- dimensional arrays are of size (1: 2000, 1: 2000), with each array element occupying one word, n=2000 for i : = 1 to 4000 do for j : =1 to 4000 do { a[i, j] : =a[i, j) *b[i, j]; b[i, j] : =c(n-i+1,j) *b[i, j] } provided the arrays are mapped into the main memory space (a) in row-major order, (b) in column-major order.

1. the program must provide following functions to extract some statistics. note that the data_list parameter specified in these functions may be the same for all functions or different for different functions—that is your choice. a skeleton file is provided on mirmir. a) open_file()prompts the user to enter a year number for the data file. the program will check whether the year is between 1990 and 2015 (both inclusive). if year number is valid, the program will try to open data file with file name ‘year. txt’, where is the year. appropriate error message should be shown if the data file cannot be opened or if the year number is invalid. this function will loop until it receives proper input and successfully opens the file. it returns a file pointer and year. i. hint: use string concatenation to construct the file name b) read_file(fp)has one parameter, a file pointer read. this function returns a list of your choosing containing data you need for other parts of this project. c) find_average(data_list) takes a list of data (of some organization of your choosing) and returns the average salary. the function does not print anything. hints: i. this is not the average of the last column of data. it is not mathematically valid to find an average by finding the average of averages—for example, in this case there are many more in the lowest category than in the highest category. ii. how many wage earners are considered in finding the average (denominator)

For which utilities, if any, does the landlord pay?

What is a sketch or blueprint of a web page that shows the structure (but not the detailed design) of basic page elements such as the logo, navigation, content, and footer?
