This is a video tutorial in the Education category where you are going to learn how to master inverse proportions in Algebra. Inverse proportions have a different rule; more means less or less means more. Let us understand this with an example. It took 175 minutes to drive to the cottage at 80 kmph. If we drive at 100 kmph instead, how long will it take? Here the speed of travel is more but the time taken to complete the journey will be less. So, this is a more means less kind of inverse prop...
In this tutorial, Peter John teaches us how to palm read: Crosses & islands on the main lines. Lines in the hand show how a person makes a change. When there is an island on the hand, this means the person needs to slow down and be careful. This could also mean their work is going to slow down or something in their career is going to change. If the island continues on throughout the hand, this means the person will manage to carry on and stay within their line of work when they are challenged...

Ever wonder how to read a binary clock? First, you must learn that in binary code there are only two numbers, one and zero. A binary clock has six columns and tells time in military time. The first two are for the hour. No light means zero. A light that is turned on is one. The first column has two dots the second column has four. if the second dot from the bottom in both columns is lit, it is 22:00 or ten o'clock. In the third column the light closest to the bottom is lit which means one. In...
Learn how to easily convert percentage values into decimals in this quick video. When converting percentages it is important to remember that a percentage simply means to divide by 100. For example, take 5%. That means 5 divided by 100 or 0.05. These can easily be done on your calculator once you understand the meaning of percentage. Another example, let's take 23%. Divide 23 by 100 and you get .23. Finally, as a last example takes 99%. Take 99 divide it by 100 and the answer will come out to...
Sugarray844 teaches you how to read the left hand in palm reading. The left hand can tell you what that person inherits from his or her family. You look at the lines, the size of the fingers and the strength of the thumb. If the thumb is strong, this means that person has strong logic. The head line is separated from the life line, which means independence in the way of thinking. The hear line is curved, which shows a break in the beginning and a good emotional side to the person. This also m...
We will be translating the sentence "twice y differs from 5 by more than two, “into a mathematical equation. The word twice generally means two times, so 2*y (because y comes next in the sentence). Differs normally means is different and a difference from something in a mathematical sentence means subtraction most of the time, thus minus five. We don't know if we’re talking about below 5 or above 5 on the number line, so we put absolute value around the equation. More than implies a greater t...
Pierre-Benoit Heriaud explains the various meanings of the French word bien. Firstly, there is one obvious meaning the common "good" or "acceptable". However, one can also use it in sentences such as "Il fait bien froid" to present the current status of the weather as being excessive in one way. In this case, it can easily be replaced with the adverb "vraiment", not losing any bit in meaning. Lastly, the word "embete" might also be a trap in that it usually means annoyed, but can be associate...

While it is common knowledge that Thomas Edison created the first light bulb, he was not the first to create a means of creating artificial light. That distinction goes to a man by the name of Humphrey Davy who created a means to light up a room called an arc light. The following video will give you a detailed step by step procedure for creating your own 19th century arc light using materials that can often be found right around the home.
This video describes how to solve direct proportions in algebra which is an important and useful skill in everyday life, school and at work. In this video one would learn key elements of a direct proportion and learn to separate them into a more means more or less means less types of proportion. For example if one had a direct proportion of the more means more type one would simply gather the logical numbers and follow the two simple rules for solving. Overall this video is simple and useful ...
Central limit theorum is easily one of the most fundamental and profound concepts in statistics and perhaps in mathematics as a whole. In probability theory, the central limit theorum (CLT) states conditions under which the mean of a suffiently large number of independent random large variables (each with finite means and variance) will be normally distributed, approximately. Huh? If you are having trouble understanding central limit theorum and need help trying to solve it, check out this tu...
This video tutorial shows how to solve inverse proportions. The tutor says that in inverse proportion it works differently than in the direct proportion. He says that in inverse proportion more means less or less means more. He uses the example of driving a car to illustrate his idea. He says that if you drive a car with more speed, you take less time to reach a place i.e. here more speed means less time. He goes on and solves a problem involving inverse proportion explaining how to solve the...

You're going to need a little money to make this pointed origami star, but not that much, unless you Mr. Moneybags or something. To keep this cheap, you can use dollar bills — five of them, which means five dollars. You can use five dollar bills, but that would mean you'd have a twenty-five dollar paper star, and unless you plan on selling it for fifty, you might just want to use some fake bills. Anything that is rectangular in shape will do. You can make a 5-pointed star or upgrade to the 6-...
Eating healthy does not mean crunching on cardboard 24/7, even if that's what your kids think. While it's always easy to reach for a neat package of Cheetos and toss that into your kid's lunchbox for school, doing so means you're giving them a hefy serving of artificial coloring (some of which has been linked to cancer), artificial flavoring, and high fructose corn syrup.
It's summer, gals, which means it's time to have fun with your makeup and break out of your nudes and neutrals mold. So no, that doesn't mean venturing into scary chocolate browns and - gasp! - even royal purples.
Proportions or ratios are fundamental concepts of mathematics. A proportions is an equation that states that two ratios are equal. Hence proportion can be written in two ways as a:b=c:d or a/b=c/d. In these equations a and d are called as extremes and b,c are called as means. So when working with proportions we can state that product of the means is equal to the product of the extremes i.e. a*d = b*c. This is obtained by cross multiplying the second form of proportions. In mathematics you are...

A rough definition of standard deviation is that it is a measure of expressing the observed variations about the average in statistical data i.e. by how much do the observed values vary from the mean. This video continues from the previous solved example and demonstrates the mathematical interpretation of the standard deviation that was calculated. We begin with stating the mean and standard deviation values and then calculating the upper and lower bounds of the data based on the standard dev...
