MT230 2010/2011 Exercise 1 (To be returned on Tuesday‚ October 5) Question 1 A mechanical jar filler is used to fill jars with coffee. The filler is set so that the mean jar fill is 205 grams. The standard deviation of the jar fills is 2.5 grams. If the population of jar fills is normally distributed‚ what percentage of jar fills will be (i) greater than 202.5 grams‚ (ii) between 201.25 and 208.75 grams‚ and (iii) greater than 212.5 grams? If coffee jars have a capacity of 200 grams‚ (iv) what percentage

MATH AND FIGURE SKATING Alexis Dillon I. Introduction This paper will be discussing the involvement of math in figure skating. There are three parts of skating that will be discussed in the essay; jumps and moves in the field. Jumps require a lot of power‚ strength and knee bend in order for the jump to be successful. I will be looking at the appropriate angle of knee bend a skater needs to successfully land a jump. Moves in the field are series of test that include certain turns

(Adams‚ 1984. p119). ‘Talk is seen to be the major instrument of learning in infancy and subsequent to that we continue to learn by talking about our dialogue with others.’ (Britton‚ 1970 p.129). However‚ research shows that‚ despite the advantages of talk‚ teachers are still not using talk as a

LESSON 1 REFLECTION It is important to critically analyze questions such as‚ what is pi? ‚ And what is the area of a circle? The obvious assumptions would be the numerical approximation 3.14 and the formula of the area of a circle‚ pi*r^2. However‚ as we soon learned Pi is the ratio of a circle’s circumference to its diameter or the number of radius squares needed to completely cover a circle exactly. And the area of a circle is the unit squares needed to cover a circle exactly‚ or the space

Math is a subject that involves the science of numbers and their operations‚ interrelations‚ combinations‚ generalizations‚ abstractions and of space configurations and their structure‚ measurement‚ transformations‚ and generalizations (Merriam- Webster‚ 2013). Depending on the person‚ math can be an easy or challenging subject to conquer. Not everyone can solve math problems with little to no effort involved. Students are often given exams to test their knowledge of the subject. In Professor Hoffman’s
