...ASSIGNMENT - 3 Answers 1 Answer 2 Answer 3 4. For what types of workloads does SJF deliver the same turnaround times as FIFO? ANSWER: - In the above case if the jobs are same in size or the jobs periodically applied (i.e. first shortest job then later second shortest job and continues) then the turnaround time of SJF is same as FIFO. 5. For what types of workloads and quantum lengths does SJF deliver the same response times as RR? ANSWER: - The response time delivered by SJF is equal to the response time of RR but this happens only when all the jobs arrived are at the point when the planning quantum of RR is bigger than the bigger occupation to be administrations in order of increasing size. 6. What happens to response time with SJF as job lengths increase? Can you use the simulator to demonstrate the trend? ANSWER: - If you suppose the length of the job increases then average response time varies (increases).If every job is sorted in increasing job order than the last job response time will be equal to the sum of current job and previous (n-1) jobs. In this way if the size of the job increases the response time will also increases for all larger jobs. 7. What happens to response time with RR as quantum lengths increase? Can you write an equation that gives the worst-case response time, given N jobs? ANSWER: - In the case of RR, the response time increases as the quantum lengths increases. This happens because the waiting time of a process for its turn to...

...students well enough. Students often learn the equality symbol misconception when they begin learning mathematics. Rather than understanding that the equal sign indicates equivalence between the expressions on the left side and the right side of an equation, students interpret the equal sign as meaning “do something” or the sign before the answer. This problem is exacerbated by many adults solving problems in the following way: 5 × 4 + 3 = ? 5 × 4 = 20 + 3 = 23 Students may also have difficulty understanding statements like 7 = 3 + 4 or 5 = 5, since these do not involve a problem on the left and an answer on the right. Falkner presented the following problem to 6th grade classes: 8 + 4 = [] + 5 All 145 students gave the answer of 12 or 17. It can be assumed that students got 12 since 8 + 4 = 12. The 17 may be from those who continued the problem: 12 + 5 = 17. Students with this misconception may also have difficulty with the idea that adding or subtracting the same amount from both sides of an equation maintains equality. Kieran gives this example: Solve for x: 2x + 3 = 5 + x 2x + 3 – 3 = 5 + x 2x = 5 + x – x – 3 2x – x = 5 – 3 x = 2 The answer is correct, but several steps of the solution contain incorrect equations. In summary, a student with this misconception will: Assume the solution to a problem is the number after the...

...Team B Calorie Count Tool PRG/211 May 5, 2014 Team B Calorie Count Tool PROBLEM STATEMENT Team B was asked to develop a program which would calculate the user’s daily intake of calories and measure those calories against the overall calories expended. The core purpose of this program will do two primary functions. First, it will record the user intake of calories as acquired through meals throughout the day. Second, the user will record caloric output associated with physical activity. This information will be calculated together to determine the caloric surplus or deficit for the user. In order for the program to execute accurately, and provide customized results, the user will be required to input personal data to include gender, age, weight, and height. This additional information is essential to determine the user’s default caloric burn rate, otherwise known as the basal metabolic rate (BMR). The BMR and the calories burned as a result of physical activity will be calculated against the intake of calories to determine the overall success for the user. As the program is executed it must: * Record user name, age, height, weight to enable more accurate calculations * Record the users specific caloric values entered for each meal * Record the user activity and caloric burn values for that activity * Calculate the basal metabolic rate (BMR) for the individual * Subtotal the total caloric values for the day * Combine the physical activity and...

The operand (the value on which the operator operates ) of the unary operator must have arithmetic or pointer type and the result is the value of the argument. Example:- If a=5 then +a means 5 If a=0 then +a means 0. If a=-4 then +a means -4. Ternary operator:- It precedes an operand. The operand of the unary operator must have arithmetic type and the result is the negation of the operand’s value. Example:- If a=5 then –a means -5 If a=0 then –a means 0 If a=-4 then –a means 4. (b) Assignment and equalto operator Assignment operator:- Equal to operator: An assignment operator assigns value In this we put the To a variable. value as it is.

...Selection statements Selection is used to select which statements are to be performed next based on a condition being true or false. Relational expressions In the solution of many problems, different actions must be taken depending on the value of the data. The if statement in C I used to implement such s decision structure in its simplest form – that of selecting a statement to be executed only if a condition is satisfied. Syntax: if(condtion) statement executed if condition is true When an executing program encounters the if statement, the condition is evaluated to determine its numerical value, which is then interpreted as either true or false. If the condition evaluates to any non-0 value (positive or negative), the condition is considered as a “true” condition and the statement following the if is executed; otherwise this statement is not executed. Relational Operators In C Relational operator | Meaning | Example | < | Less than | age < 30 | > | Greater than | height > 6.2 | <= | Less than or equal to | taxable <= 200000 | >= | Greater than or equal to | temp >= 98.6 | == | Equal to | grade == 100 | != | Not equal to | number !=250 | In creating relational expressions, the relational operators must be typed exactly as given in the above table. Thus, although the following relational expressions are all valid: age > 40 length <= 50 temp >= 98.6 3 < 4 flag == done day != 5 The following are invalid: length =< 50 ...

...Running Head: Team Assignment 1 Team Assignment Disparity of Wages on the Labor Market part 2 RES/351 University of Phoenix Team Assignment 2 What are the research questions? 1. Do minorities get penalized when it comes to hiring and wages? 2. What is the average annual wages for each job type in the local region? 3. What qualities affect the wages earned annually by employees? These questions will help to lead the direction of our paper, as well as to help ensure that our group can keep the focus of the paper to stay where we want it to be. Identify one dependent variable among the variables in the Data Set for the organization assigned to your team. This variable must be the most suitable one among the variables whose values change with the changes in the values of other variables in the Data Set. For this project, it has become clear that the dependant variable in our data set is wages. Independent variables that are a driving force, in this case, are going to be race, experience, and gender. These things can have an effect on wages that are to be set but being a Union member does not seem to have an impact on that. We also noticed that education did not seem to have an impact on the wages set for employees. What...

...Law Written Assignment 3 Case Study 1 Parks, a 7-foot, 265-pound center for the San Diego Slick, objected when his contract was assigned from the ABC Corporation to the XYZ Corporation, the team’s new owner. The change of owners did not cause a change in the composition of the team although a new coach was hired. Parks’s compensation and his responsibilities remained the same. Was this contract assignable? Facts of the Case: 1) Parks contract was assigned from the ABC Corporation to XYZ Corporation. 2) Parks compensation and his responsibilities remained the same. Issues: 1) The reason why we are in court today is to identify if Park’s contract was assignable. Rules of the Law: 1) Personal Service Contract – The parties agree that a personal service contract may be assigned. This allows the trade of an athlete from one team to another team. 2) Notice of Assignment – Assignee is under a duty to notify the obligor that the assignment has been made and performance must be rendered to the assignee. 3) Anti-Assignment Clause – Prohibits the assignment of rights under the contract. 4) Approval Clause – requires that the obligor approves any assignment of contract. Analysis & Conclusion: Since we do not have all the facts we can assume the following: 1) Parks contract did include the Personal service contract. 2) Notice of assignment was made by XYZ Corporation. 3) Parks contract did NOT include Anti-Assignment Clause. ...

...Reflection assignment In this assignment I will be using the Gibbs Reflective Model, reference, to reflect on an incident that occurred in placement that demonstrates an understanding of the Outcome : 3.1: Demonstrate that they respect diversity and individual preferences and value differences, regardless of their own personal views. To do this I will first, briefly describe the event, supporting my outline with relevant information. I will then explore the event, and discuss why it is important and how it relates to the learning outcome. I will also be discussing why materials such as law and guidelines say this is important. I will then proceed to analyse the incident by breaking it down and picking out the main features of the experience, discussing why they are important, whilst linking the main points together. I will attempt to think about opposing arguments to what I have explored, and discuss the advantages and disadvantages of the arguments. Finally I will be using SMART goals, to create an action plan for future development. Explain incident with evidence Whilst on a shift, we had an elderly patient arrive on the ward. The patient suffered from a Frank Haematuria, Colovesciular fistula as well as incontinence.

...Janell Taylor 10/23/12 Implicit Test I found the test to be very interesting and I don’t like timed tests because I need time to think about my answer to be sure and confident about my choice. I don’t agree with the results because they said I made too many errors and I don’t understand that because that was just one part where I was making too many errors. It has helped me out in those areas of different topics, but I just wish I had more time. I guess I would say that the answers wasn’t valid enough for me because it didn’t really give me a score because I made too many errors, so I don’t agree with that too much. I believe prejudice is difficult to measure because I don’t agree with it and don’t like the fact that it’s very big and can get worse if we don’t come together to get in one accord to help each other and make the world better to live in dealing with different people and feelings. I think measuring prejudice can be a tough thing to deal with and handle because of the many people that are prejudice, which are hurting and harming many situations and people that’s trying to make it while being equal to everyone regardless of what. I would have to take the test over to get a better score because I felt that wasn’t fair because I made too many errors to get a...
