Mean of a population

There are several measures of central tendency. By far the most frequently utilized of these measures is the mean of a population. Remember that the source of the data that you want to analyze always comes from what is called a population. If you are interested in the average high temperature in your area for the month of July, then your population would be the 31 daily high temperatures in July, and the mean would be the total of these temperatures divided by 31. Now, suppose you calculate a mean of a population and you want to know how representative that mean is of a random data point in that population. In other words, is the data bunched tightly around the mean, or is it more loosel... click for more

Proofs

1- prove that an intrnal bisectore of an angle of a tiangle divides the opposite sides (internally) into two segments propotional to the adjacent sides of the triangle i.e prove DB/DC = AB/AC. 2- given triangle ABC with incenter I, prove that (shown in document) 3- x = ? , y = ? as shown in figure(document)

1- Given triangle ABC, prove that an internal bisectors of an angle of a triangle divides the opposite sides (internally) into two segments proportional to the adjacent sides of the triangle. That is prove that DB/DC = AB/AC. (D is the point where e internal bisector of
