X2

video lecture watching behaviors of learners and lecturers’ gender was found (X2 = 29.31, N = 10282, p < .001). 62% of completely watched events belonged to female lecturers’ videos. A Chi-square test of independence was calculated to compare the viewing behaviors of learners and lecturers’ age in “40 and below” and “below 40”. There was a significant relationship between viewing behaviors of learners and lecturers’ age, (X2 = 14.46, N = 10282, p < .001). 57% of completely watched…

We will now rewrite the formula to (1x + 4)(1x + 5) = 0, however when we use our FOIL method we will notice that it turns out to be x2 + 5x + 4x + 20 = x2 + 9x + 20 = 0 which in no shape or form is the same as x2 – 8x – 20 = 0 because of the negative numbers and the middle does not match. We will continue to input numbers into b and d to create the equation to match x2 – 8x – 20 = 0. With this being said we must also keep in mind that a and c will be multiplied to equal positive 1 and that the…

Introduction In the music industry, there will always be a difference between artists; whether we realize it or not. One obvious difference is race. We as human beings have come so far in the battle against racism and have left that chapter behind us. However, small traces of racism still live today inside of most people (internalized racism). One example of how internalized racism lives on is through the music industry. For this investigation, I wanted to see the differences in success of an…

Part A: Background Information Acids and bases are very common in today’s society, and they can be found in most households. Acids can be found as by-products of air pollution, concrete cleaner, food flavouring and is produced by the muscle. Bases are found in most cleaning products as ammonia or sodium hydroxide, and they also treat indigestion. There are many ways that acids and bases can be defined by their chemical properties. The Bronsted-Lowry definition states that acids are proton…

1. Derive the mathematical expression for the Lorentz transformation equation. relative orientation of the co-ordinate systems indicated in fig.2 A light-signal, which is proceeding along the positive axis of x, is transmitted according to the equation : x - ct = 0 _______ (1). Since the same light-signal has to be transmitted relative to K1 with the velocity c, the propagation relative to the system K1 will be represented by the analogous formula x' - ct' = 0 _______(2) therefore:…

Consider a liner spring of spring constant k and undeformed length L. An external force F acts on the spring, which stretches the spring from position 1 to 2 (Fig. 2.4). (a) (b) Fig. 2.4 The deformation of the spring at position 1 and 2 are x1 and x2 respectively. When the spring is stretched, the spring force (Fs) tries to restore the spring to its original position. So the spring force Fs acts opposite to the displacement. We also know that force developed in a liner spring is directly…

In the plane, the distance between two points (x1, y1) and (x2, y2) is given by the Pythagorean theorem as follows d=√((x_2-x_1 )^2+(y_2-y_1 )^2 ). In three-dimensional Euclidean space, the distance between two points (x1, y1, z1) and (x2, y2, z2) is d=√((x_2-x_1 )^2+(y_2-y_1 )^2+(z_2-z_1 )^2 ). In general, the distance between two points x, y in space with n-dimensional Euclidean R is calculated…

Intro: Newtons Method: Haley F. / Andrew H. Newton’s Method, also known as Newton-Raphson method, is a method used for finding the zeros, roots or in more simple terms where any given function exactly crosses the x access. In calculus we may be presented with problems given that we cannot find a definite answer to, but we can use Newton’s Method to calculate a group of answers that get closer and closer to the actual solution. Newton’s Method has given the world of calculus a method of…
