Suppose you work at a music store and have four CDs you wish to arrange from left to right on a display shelf. The four CDs are hip-hop‚ country‚ rock‚ and alternative (shorthand: H‚ C‚ R‚ A). How many options do you have? Solution: If you select H first then you still have three options remaining. If you then pick C‚ you have two CDs to choose from. You can find the number of ways to arrange your display by the factorial rule: for the first choice (event) you have 4 choices; for the second‚ 3;

Vitamin C –A Natural Antioxidant Concept: Vitamin C (ascorbic acid) is an antioxidant. The amount of vitamin C content in food can be found out by titrating with an oxidising agent‚ e.g. iodine. In the reaction‚ vitamin C is oxidised‚ while iodine is reduced to iodide ions. The endpoint is determined by the formation of blue-black starch-iodine complex when all vitamin C is oxidised and excess iodine is free to react with the starch solution added as indicator. Introduction Vitamin C is an important

MATH AND MUSIC MATH AND MUSIC Math and Music Math and music are connected in many ways. Math is seen to be as very precise. Music is often seen as a way to express emotion. They are actually both very closely related together. Music is an expression of scales and notes that are strung together to make sound. Math is the subject of numbers and symbols used to write formulas and equations. At its foundation‚ music and math are related. In this essay‚ you will show that math and music

ever going to use this in real life?" You’ll find the answer here! Or You may find yourself wondering what use we have for some of the knowledge we obtain from math class in school. It is sometimes difficult for students to appreciate the importance of Mathematics. They often find the subject boring and hard to understand. With this project we will hopefully help our students realize that Mathematics is not just a subject on their time-table but a tool they use in their everyday life. "Mathematics

is really long‚ but this essay is a short and to the point summery of the entire history. The history of Babylonia started near the end of the year 2000 BC‚ when invaders were attacking the Sumer kingdom.
