Cost Windows Vista and Vaio Fit Essay

Cost Windows Vista and Vaio Fit Essay Cost: Windows Vista and Vaio Fit Essay Costs and Benefits Bryant & Stratton College Today we will talk about the cost and benefits for getting new laptop’s for Election management bodies (EMBs). This packet will include the initial costs of purchasing new hardware and software, the hiring of consultants to set up the new system. Also the costs for maintenance and management costs to keep the laptop’s running. This will show you why we need new laptops. The process of getting new laptops is for the new technology that would replace the old ones we have had for 6 years now. The laptops that are used right now are Dell Latitude E6400 notebook pc with an operating system of 32-bit Windows Vista Business. This has a processor that is called Intel Pentium. It has a clock rate of 60 MHz- 200MHz. We will be upgrading to a VAIO FIT laptop from Sony that comes with the new 3rd generation Intel Core i5 dual processer and has a 64-bit Windows 8 business. The Dell Latitude E6400 that is used now has a lot of problems. One of them is the time it takes to open a prog ram and find the right info you need. It takes all most 2 minutes just to pull up all accounts for one customer. They are starting to freeze when more than 2 apps are open. This is a major problem because 80% of the time we need to have a lot more open to help the customer’s. If you continue to use these old computers you may lose data because they are all 90% full. The Dell Latitude E6400 has now wireless network. Now the VAIO FIT is a newer laptop that costs $549.00 and the ASUS X44L cost us $399.00. The new VAIO FIT comes with more space than what we have now. The VAIO FIT comes with 8GB and the Dell Latitude E6400 only has 2GB. The VAIO FIT has will help by speeding up time it take for a program to open because of the new processor speed of 1.80Ghz with Intel turbo boost technology up to 2.70GHz. It also a good battery life that goes up to 5 hours with a solid state drive that has 2GB dedicated to it. The VAIO FIT comes with HHD (Hybrid Hard Drive) this is one the magne tic-hard disk drives today and the flash memory is great. This gives you faster access to your data, also with a faster boot up time compared to standard hard drive. The VAIO FIT also comes with rapid wake this helps when the computer is left on. When it goes to sleep you will be able to resume in two seconds with data safe and secure. There is an extraordinary web camera that is built-in this comes with Exmor R@ CMOS Sensor technology. The benefits of applying this new laptop to EMBs are better customer service because they will not have to wait long to get the info they will need to help them. With bigger memory you will be able to save more info on the customer. One of the main benefits is the wireless network that comes with new VAIO FIT. This helps because if you have to travel outside of the work space and still needs computer to wrap up a sale. This saves time for both you in the customer. Some of the possible problems that may come with this will be the training of the emplo yees from Windows Vista to Windows 8. They will also need to learn how to find all the new files and where they are located in Windows 8. Here are some of the estimate costs that involved in getting this new laptop. The VAIO FIT cost $549.00 and we times that by 10 will cost us $5490.00. The cost for a WRT54GL Wireless-G Router is $49.99 we will need 4 one for each corners of the building. The price for this is $200.00 plus $100 for wire. There will be an ongoing fee for regular maintenance will be $400 a year. If there is a major technology fails there will be a charge of $100 an hour with max amount of $1000.00. Hiring a consultant to train all the workers and to install all computers and a wireless network will cost $3000.00. As of now we have major issues with the system that cost us $500.00 for each time they come out. Within the past 3 years there have been 10

What Is (and Isnt) on the AP Statistics Formula Sheet

What Is (and Isn't) on the AP Statistics Formula Sheet SAT / ACT Prep Online Guides and Tips If you're going to be taking the AP Statistics exam, you're in luck! During the test, you'll have access to a formula sheet that has many useful equations. However, you need to know exactly what's on the AP Statistics formula sheet and how to use it before test day in order for it to be helpful. In this guide, we go over everything you need to know about the AP Stats formula sheet. We'll explain the exact equations that it includes, show you what the formula sheet looks like, go over a few important equations it doesn't contain, and give you tips on how to get the most out of it. What's on the AP Statistics Formula Sheet? The AP Stats formula sheet is actually three pages of statistics formulas that you'll be given on test day. The formulas will be at the beginning of both the multiple-choice and free-response sections of the test, so you'll have access to them for the entire AP exam. That's great because that means you don't need to memorize any of these formulas! What's on this AP statistics cheat sheet? You can see exactly what the formula sheet will look like here as well as below. The formula sheet has three sections, and each section takes up one page. Below are screenshots of the formula sheet, along with a list of the equations it includes (ordered from the top of the sheet to the bottom of the last page). Descriptive Statistics Formulas Sample mean Sample standard deviation Pooled sample standard error Simple linear regression line Regression coefficient Regression slope intercept Sample correlation coefficient Regression coefficient Standard error of regression slope Probability Formulas Rule of addition Rule of multiplication Expected value of $X$ Variance of $X$ Binomial formula Mean of binomial distribution Standard deviation of binomial distribution Mean of sampling distribution of the proportion Standard deviation of sampling distribution of the proportion Mean of sampling distribution of the mean Standard deviation of the sampling distribution of the mean Inferential Statistics Formulas Standardized test statistic Confidence interval Standard deviation of sample mean Standard deviation of proportion Standard deviation of difference of sample means Standard deviation of difference of sample proportions Chi-square test statistic What Isn't on the AP Statistics Reference Sheet That You Should Know? The AP Statistics formula sheet contains pretty much all the equations you need to know for the exam, but there are some equations they've left out that may come in handy on test day. Below are the most important of these. Be sure to memorize them because they won't be listed on the AP Stats formula sheet! Descriptive Statistics Interquartile Range The interquartile range, or IQR, is the middle 50% of values when ordered from lowest to highest. The IQR is the difference between the 75th and 25th percentiles, or the first quartile subtracted from the third quartile. The IQR is used to show dispersion, and it can be a useful way to describe the data in boxplots, histograms, scatterplots, etc. The equation is IQR = Q3-Q1 You can also use IQR to determine if an outlier exists. A commonly used formula is if a data point is more than $\bo 1.5*$IQR above Q3 or below Q1, then it's an outlier. Residuals The residual (e) is the difference between the observed value of the dependent variable ($y$) and the predicted value ($Ã… ·$). It's used in regression analysis. Each data point has one residual. The formula looks like this: $\bi e \bo= \bi y \bo - \bi Ã… ·$ Both the sum of the residuals and the mean of the residuals are equal to zero, or $ÃŽ £ e = 0$ and $e = 0$. Probability Bayes' Theorem Bayes' theorem is useful for calculating conditional probabilities. You'll use conditional probability when trying to find the probability of an event given that another event has already occurred. Conditional probability questions usually follow a format similar to "Given $x$, what is the probability that $y$ occurs?" Use Bayes' theorem to solve them. Bayes' Theorem: $P(A | B) = {P(B | A) * P(A)}/{P(B)}$ Tips for Getting the Most out of the AP Stats Formula Sheet As you can see, the AP Statistics formula sheet can be very useful during the exam since it helps you avoid memorizing long lists of equations. There are some tips to getting the most out of it though, and we go over the three most important in this section. #1: Know How to Use the Formulas It seems like obvious advice, but it's very easy to take a glance at the AP Statistics cheat sheet and move on, knowing you'll have it with you on the test. However, test day is not when you want to be trying to understand what the different formulas mean or how to use them. If you go into the AP exam not sure of what's on the formula sheet, you'll lose tons of valuable time searching for the right equations and struggling with how to use them properly. Well before exam day, be sure to go through every formula on the sheet and make sure you understand it and know how to use it. The College Board includes each of these formulas because they think they're necessary for doing well on the AP Statistics exam, so you should trust them and make sure you know them! If you're not sure how to use some of the equations, here's a helpful site that goes over what each of the formulas is used for. #2: Know Calculator Shortcuts You're allowed a graphing calculator for the entire exam, and you should take advantage of some of the nifty things it does. Calculator shortcuts can save you precious time on the test by quickly solving certain AP Statistics equations and finding pieces of data. They also give you a way to check your work for some problems. Stanford has a handy list of calculator shortcuts you can use with your graphing calculator. There are two caveats though. First, don't become so dependent on your calculator that you forget how to solve the equations on your own or the logic behind them. Second, you should use calculator shortcuts primarily for the multiple-choice section of the test, where you just have to select the correct answer choice. For the free-response section of the exam, you'll need to show all the work you did for each question, and simply writing which shortcut you plugged into your calculator won't cut it. Use the shortcuts primarily to check your work on free response. #3: Take Practice Tests With the Formula Sheet Answering practice questions and taking practice tests using the AP Statistics formula sheet is also key to doing well on the exam. You should take several practice AP tests before the actual exam, and for each of them you should use the official AP Statistics formula sheet. Your teacher will also likely give you a copy of the formula sheet for your in-class exams, so you can get some practice in there too. If you need help finding practice tests, check out our guide specifically on where to find the best AP Statistics practice questions and tests. Summary: Using the AP Statistics Formula Sheet The AP Statistics reference sheet can be a big help during the exam, but only if you already know what's on it and how to use it. The formula sheet is actually three pages that contain useful equations in descriptive statistics, probability, and inferential statistics. While this AP Statistics cheat sheet doesn't contain everything you need to know, it does include many key AP Statistics equations that you'll need to use on the test. In order to get the most out of your AP Stats formula sheet, make sure you know all the formulas, pick up some useful calculator shortcuts, and be sure to take some practice tests with the AP Statistics reference sheet.
