Negative Slope and Negative Correlation

In mathematics, the slope of a line (m) describes how rapidly or slowly change is occurring and in which direction, whether positive or negative. Linear functions—those whose graph is a straight line—have four possible types of slope: positive, negative, zero, and undefined.  A function with a positive slope is represented by a line that goes up from left to right, while a function with a negative slope is represented by a line that goes down from left to right. A function with zero slope is represented by a horizontal line, and a function with an undefined slope is represented by a vertical line. Slope is usually expressed as an absolute value. A positive value indicates a positive slope, while a negative value indicates a negative slope. In the function y 3x, for example, the slope is positive 3, the coefficient of x. In statistics, a graph with a negative slope represents a negative correlation between two variables. This means that as one variable increases, the other decreases and vice versa. Negative correlation represents a significant relationship between the variables x and y, which, depending on what they are modeling, can be understood as input and output, or cause and effect. How to Find Slope Negative slope is calculated just like any other type of slope. You can find it by dividing the rise of two points (the difference along the vertical or y-axis) by the run (the difference along the x-axis). Just remember that the rise is really a fall, so the resulting number will be negative. The formula for the slope can be expressed as follows: m (y2 - y1) / (x2 - x1) Once you graph the line, youll see that the slope is negative because the line goes down from left to right. Even without drawing a graph, you will be able to see that the slope is negative simply by calculating m using the values given for the two points. For example, suppose the slope of a line that contains the two points (2,-1) and (1,1) is: m [1 - (-1)] / (1 - 2) m (1 1) / -1 m 2 / -1 m -2 A slope of -2 means that for every positive change in x, there will be twice as much negative change in y. Negative Slope Negative Correlation A negative slope demonstrates a negative correlation between the following: Variables x and yInput and outputIndependent variable and dependent variableCause and effect Negative correlation occurs when the two variables of a function move in opposite directions. As the value of x increases, the value of y decreases. Likewise, as the value of x decreases, the value of y increases. Negative correlation, then, indicates a clear relationship between the variables, meaning one affects the other in a meaningful way. In a scientific experiment, a negative correlation would show that an increase in the independent variable (the one manipulated by the researcher) would cause a decrease in the dependent variable (the one measured by the researcher). For example, a scientist might find that as predators are introduced into an environment, the number of prey gets smaller. In other words, there is a negative correlation between number of predators and number of prey. Real-World Examples A simple example of negative slope in the real world is going down a hill. The farther you travel, the farther down you drop. This can be represented as a mathematical function where x equals the distance traveled and y equals the elevation. Other examples of negative slope demonstrate the relationship between two variables might include: Mr. Nguyen drinks caffeinated coffee two hours before his bedtime. The more cups of coffee he drinks (input), the fewer hours he will sleep (output). Aisha is purchasing a plane ticket. The fewer days between the purchase date and the departure date (input), the more money Aisha will have to spend on airfare (output). John is spending some of the money from his last paycheck on presents for his children. The more money John spends (input), the less money he will have in his bank account (output). Mike has an exam at the end of the week. Unfortunately, he would rather spend his time watching sports on TV than studying for the test. The more time Mike spends watching TV (input), the lower Mikes score will be on the exam (output). (In contrast, the relationship between time spent studying and exam score would be represented by a positive correlation since an increase in studying would lead to a higher score.)

Hacking Can Not Be Ethical - 1681 Words

Hacking cannot be considered ethical due to the fact that it damages a company s reputation. Hackers have no care in the world about the negatives that happen to you. They may not have anything against you but what you stand for. Erickson was the owner of a website known for political debates was hacked and his page on which he spent thousands of dollars on was hacked by Anonymous and became malicious. â€Å"Erickson spent $1,500 to rebuild his site with enhanced security measures.

What is Open Source Licensing Essay - 782 Words

As illustrated above, open source licensing is becoming more and more dominant, especially as long as software is provided in a digital form. The purpose of this paper was to observe if and how the open source software licensing regime has challenged the protection granted to software under the intellectual property rights. In general, the outcome is that the distinct production and distribution model of open source licenses, while different, can be compatible with the legal framework of intellectual property rights protection and serve different purposes. However, a number of remaining uncertainties around the open source licenses leave room for improvements such as the possibility to make some adaptations to the license terms. The†¦show more content†¦The dual licensing model was suggested to be an effective solution for combining both licensing regimes and for overcoming legal ambiguities. Finally, the implications of software patenting were considered to be harmful for open source development and respectively open source licenses seem to be insufficient in dealing with this issue. All the conclusions and points made throughout the paper can be summarized as follows. In essence, the most important legal difference between proprietary software and Open Source is the scope of rights given to the users. Free and open source software and licenses have given an alternative to proprietary distribution but a number of these licenses in some ways can be described as more ambitious than the typical proprietary end user license agreements. This is due to the fact that the legal situation of open source is by no means as clear and definite as the drafters of the licenses intend it to be. A second resulting remark is that while copyleft and open source in general, were originally adopted as alternative and even â€Å"in controversy† with the theory of intellectual property rights, it seems that they are influenced by it and, to a certain extent, they rely upon copyright law for their enforcement. Nevertheless, the open source movement has used some features of intellectual property rights to quite different ends.

Wearing a dust storm and a mask made from a flour poke, the brigand pointed a double- barreled scattergun at the driver and said, Throw down the box! I? ve labored long and hard for staff of life, For award and for wealths, But on my maizes excessively long you? ve tred You fine-haired boies of bitches. When the posse arrived subsequently, all they found was a bill of lading with the above poetry fastidiously written on its dorsum, each line in a different manus. About a twelvemonth subsequently, on July 25 of 1878, the PO8 struck once more. A phase from Quincy to Oroville slowed to do a hard bend a long the Feather River, the cloaked adult male stepped out of the shrubs and asked that the box be thrown down.

Let come what will I? ll attempt it on, My status can? t be worse ; And if there? s money in that box ? Tis munny in my bag! Once once more the lines were written in changing custodies and the work signed Black Bart, the PO8. In order to do the main roads safe one time once more, Governor William Irwin posted a $ 300 wages for the gaining control of the brigand, to which Wells Fargo A ; Co. added another $ 300. Another $ 20 contributed by the postal governments. The wages went unclaimed for five old ages, during which Black Bart apparently robbed at will. Often puting low for several months, Bart would all of a sudden travel on a fling and rob three or four phases in every bit many hebdomads, and so disappear without a hint. Black Bart? s endowment for covering great distances on pes in impossibly short times was no uncertainty a great plus in his life as a highjacker. In another, and it t urned out to be his last, stage robbery McConnell ( the phase driver ) turned his caput to happen the muzzle of a double-barrelled scattergun looking at him. You see, Bart knew that this phase was transporting gold coins and gold amalgam with it. What Bart didn? T know is that in the forests following the phase was a immature huntsman that had gotten off a few stat mis back to make some hunting. Ordering McConnell to unhitch the squad and walk them up the hill, Bart so entered the phase and commenced to interrupt unfastened the chest. Meanwhile, Jimmy ( the huntsman ) someway managed to run into McConnell off from the phase. The two took screen and watched as Black Bart backed out of the phase with his booty. McConnell so seized the rifle from the male child and unfastened fire on the robber. He missed, twice, after which Jimmy took the rifle and fired, doing Bart to falter before vanishing into the coppice. Sheriff Ben Thorn of Calaveras County reached the armed robbery site that afternoon and organized the posse to seek for hints.

Hume in San Francisco, whereupon Hume turned the hankie over to particular operative Harry Morse who instantly went to work on tracking the laundry grade. A hebdomad subsequently, on November 12, the wash was found and the proprietor of the hankie identified as one Charles E. Bolton. Bart was arrested and after drawn-out oppugning decided to squeal to the robbery and demo his capturers where he had hidden the amalgam, trusting that this would do it easier for him when he came to test. After the amalgam was recovered, Bart appeared on November 17 before Superior Court Judge C.V. Gottschalk at San Andreas. Dur ing his calling as a highjacker, Black Bart robbed 28 phases ; when he was caught he confessed to merely the last and was sentenced on the footing of that one entirely. He received six old ages in San Quentin Prison. Released from prison on January 21 of 1888, Charles E. Bolton disappeared from sight a few hebdomads subsequently and was neer seen once more.
