What is the IEEE 754 32-bit floating-point representation of the hexadecimal number 0x8F910074? Specify if the number is positive or negative and explain why. What is the decimal representation of the exponent and what is the binary representation of the mantissa? 

29. Consider the Cocktail Sort (code 4) algorithm described in the appendix. What is the fewest number of lines of code that would have to be added, removed, or changed in order for this algorithm to sort from largest to smallest? (A) Everything inside the second for loop. (B) 3 (C) 1 (D) 2 (E) Everything inside both for loops. Binary answers For the following questions you are to use your choices as they were the representation of a binary number. More precisely, A = 24, B = 23, C = 22, D = 21, and E = 20 position in a base 2 number. For example if you wanted to answer the number 23, you would translate it first as base 2 number, which is 10111, you would blacken A, C, D and E.2 Lets look at this process on your answer sheet, we have these 5 circle you can blacken. Normally you only pick one, here you might have to blacken more than one! @ ® © D ® Following the previous example, the answer we want to input is 23, its binary representation is 10111, hence the circle you would blacken are the following:

4. In this question, you will be shown a snippet of code. You will then be shown the output from either the compiler or the Java virtual machine and be asked what the error is and how to fix it. In each case, your answer should include the line number of the problem, a one or two sentence explanation as to why the issue occurs, and a specific fix for the problem. Your fix should mention the exact line or lines of code you'd add/change/delete. Total for this question (5 parts): (15 points) (a) Consider the following class: import java.util.Scanner; public class Hockeystandings //This method should calculate the percentage of games in which the team lost. public static double computePercentageLosses (int numwins, int numLosses) return numLosses/ (numwins + numLosses) * 100; public static void main(String[] args) { Scanner reader - new Scanner (System.in); System.out.println("Enter the number of wins for the Maple Leafs"); int numLeafwins = reader.nextInt (); System.out.println("Enter the number of losses for the Maple Leafs"); int numLeaflosses-reader.nextInt (); System.out.println("Enter the number of wins for the Canadiens"); int numCanadienswins – reader.nextInt (); System.out.println("Enter the number of losses for the Canadiens"); int numCanadienslosses = reader.nextInt (); double mapleLeafs Record - computePercentage Losses (numLeafwins, numLeaf Losses); double canadienskecord - computePercentage Losses (numCanadienswins, nuCanadienslos305): if (canadiens Record > mapleleafsRecord) { System.out.println("Of course the Leafs did worse."); else { System.out.println("Wow, that hasn't happened for a long time!"); The point of the program is to ask the user to enter numbers representing the wins and losses of the Maple Leafs and Canadiens in a season. The code compiles successfully and when you run the program, you enter the values: 2 80 40 42 into the keyboard. You expect that the program will output the message Of course the Leafs did worse since they had fewer wins. However, to your surprise, the output of the program is: Wow, that hasn't happened for a long time! Why is this the case and fix the error?
