Exercise#3: Write a program that performs the following: Declare a two arrays called arrayA and arrayB that holds integer and the size of each array is given by the user. b. The main method calls a method called fillArray(...) of type void to fill an array with a set of generated random integers between low and high (both inclusive). This method should be called twice to fill arrayA and then arrayB. (the values of High and low are read in the main method. C. The main method calls another method called printArray (...) of type void to display the elements of the array 5 elements per lines. This method should be called twice to print arrayA and then arrayB. d. The main method calls another method called count (...) of type integer to count and return the total number of integers greater than a value enter by the user. Then the main methods calls another method called isSame( ... ) of type boolean to check if the two arrays arrayA and arrayB have the same element or not. f. The main method calls a method called findAverage(...) of type double that calculates and returns average of all the values I arrayA. g. Then, main method calls a method called aboveAverage(...) of type integer that finds and returns how many numbers in arrayB are above the average of the elements of arrayA. e.​

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.)

Consider a slotted aloha system, where the time slot equals the fixed duration of each packet. assume that there are 4 stations a,b,c,d sharing the medium. (a) stations a,b,c,d receive one packet each from higher layers at times 1.3, 1.5, 2.6,5.7 respectively. show which transmissions take place when, according to the slottedaloha protocol; describe all transmissions until all four packets have been successful.when needed, each station has access to the following sequence of random number, provided by a random number generator and drawn uniformly between 0 and 1: (1) station a draws numbers: 0.31, 0.27, 0.78, 0.9, 0.9, 0.11, 0. (2) station b draws numbers: 0.45, 0.28, 0.11, 0.83, 0.37, 0.22, 0. (3)station c draws numbers: 0.1, 0.2, 0.3, 0.4, 0. (4) station d draws numbers: 0.36, 0.77, 0.9, 0.1, 0.1, 0.1, 0.1, 0. (b) in slotted aloha, a station transmits in each time slot with a given probability. what probabilities would you assign to each of the four stations so as to: (i) maximize the efficiency of the protocol? (ii) maximize fairness among the four stations? (c) will the efficiency increase or decrease if we modify slotted aloha as follows: (i) get rid of slots and allow stations to transmit immediately? (ii) implement carrier sensing? (iii) implement collision detection? (iv) implement collision avoidance?

In cell h5 enter a formula that will calculate the percentage of attendees that went to the altamonte springs job fair in 2018.
