Suppose Pep/9 contains the following four hexadecimal A: 19AC X: FE20 Mem(0A3F]: FF00 Mem[0A41]: 103D If it has these values before each of the following statements executes what are the four hexadecimal values after each statement executes? (a) CIOA3F (b) D10A3F c) D90A41 (d) F10A41 (e) E90A3F (f) 790A41 (g) 710A3F (h) 910A3F (i) 07 6

Dean wants a quick way to look up staff members by their staff id. in cell q3, nest the existing vlookup function in an iferror function. if the vlookup function returns an error result, the text “invalid staff id” should be displayed by the formula. (hint: you can test that this formula is working by changing the value in cell q2 to 0, but remember to set the value of cell q2 back to 1036 when the testing is complete.)

Avariable of the data type arrays is storing 10 quantities. what is true about these quantities? a. the quantities all have different characteristics. b. the quantities all have the same characteristics. c. five quantities have the same and five have different characteristics. d. it is necessary for all quantities to be integers. e. it is necessary for all quantities to be characters.

Use a physical stopwatch to record the length of time it takes to run the program. calculate the difference obtained by calls to the method system. currenttimemillis() just before the start of the algorithm and just after the end of the algorithm. calculate the difference obtained by calls to the method system. currenttimemillis() at the start of the program and at the end of the program so that the elapsed time includes the display of the result. use the value returned by the method system. currenttimemillis() just after the end of the algorithm as the elapsed time.
