MATHEMATICS SL INTERNAL ASSESSMENT TYPE 1 LACSAP’S FRACTIONS 10/11/2012 Tracy Braganza IB2T In mathematics‚ Lacsap’s fractions are based upon Pascal’s triangle. In this portfolio‚ the aim that was given was to consider a set of numbers that are presented in a symmetrical pattern‚ deduce a general statement and also to determine the limitations of the general statement that have been found. The answers in this portfolio will be attained with the help of a GDC calculator (GDC – TI84 Plus

Week 5 - Discussion 1 This Discussion will give you the opportunity to calculate or identify the three measures of central tendency. You will be asked to select an appropriate real life situation in which one measure would be more appropriate than the other two measures of center. 1. Select a topic of interest to you and record the topic in your posting‚ for example: “What is the average number of hours people watch TV every week?” Make sure the question you ask will be answered with a number‚

Kelly Panizza Assignment # 1 Algorithm-Spring 2011 1. Do some research on al-Khorezmi (also al-Khwarizmi)‚ the man from whose name the word “algorithm” is derived. In particular‚ you should learn what the origins of the words “algorithm” and “algebra” have in common. R: / the word “Algorithm” or “Algorism” in some other writing versions‚ comes from the name Al-Khwarizmi (c. 780-850)‚ a Persian mathematician‚ astronomer‚ geographer

6. Use Chebyshev ’s theorem to tell the probability that a number lies in the following interval. Round your results to the nearest whole percent. 2) Between 35 and 65 Ans: we have z = (35-50)/6 = -2.5 and z = (65-50)/6 = 2.5 So 35 and 65 lies within 2.5 standard deviation of mean By Chebyshev’s theorem we have the probability as 1 -1/k2 ‚ where k is the standard deviation within which the numbers In this case k = 2.5 So the required probability = 1 -1/2.52 => 0.84 =>at least 84%

Discrete and Continuous Probability All probability distributions can be categorized as discrete probability distributions or as continuous probability distributions (stattrek.com). A random variable is represented by “x” and it is the result of the discrete or continuous probability. A discrete probability is a random variable that can either be a finite or infinite of countable numbers. For example‚ the number of people who are online at the same time taking a statistics class at CTU on

Mrs. Coyer’s Tenth Grade Journalism Class Choosing this project to use as my final presentation was based off of a moral decision to use this class to its full potential. I came into TCXG 464 with the idea of an open mind towards teaching but also having a gut instinct that writing was my passion and teaching was more of a learned science. Yet‚ as I entered the school for my observation I began to get cold feet about the whole idea of passing on the idea of analyzing a writing text book. The
