general‚ very powerful multivariate analysis technique that includes specialized versions of a number of other analysis methods as special cases. We will assume that you are familiar with the basic logic of statistical reasoning as described in Elementary Concepts. Moreover‚ we will also assume that you are familiar with the concepts of variance‚ covariance‚ and correlation; if not‚ we advise that you read the Basic Statistics section at this point. Although it is not absolutely necessary‚ it is

Math Summative: Fishing Rods Fishing Rods A fishing rod requires guides for the line so that it does not tangle and so that the line casts easily and efficiently. In this task‚ you will develop a mathematical model for the placement of line guides on a fishing rod. The Diagram shows a fishing rod with eight guides‚ plus a guide at the tip of the rod. Leo has a fishing rod with overall length 230 cm. The table shown below gives the distances for each of the line guides from the tip of

Logan’s Logo So Logan has devised a logo for her company which is a square divided into 3 sections with 2 functions. Our objective is to find what functions fit the two curves on her logo and also make it fit on two other sizes of her logo. Just looking at the shape of the lines 2 types of functions immediately jump into my head‚ sinusoidal and cubic. I first traced a grid onto the original copy of the logo I was given in order to get points to start trying to form a function to match the design

QUADRATIC EQUATIONS Quadratic equations Any equation of the form ax2 + bx + c=0‚ where a‚b‚c are real numbers‚ a 0 is a quadratic equation. For example‚ 2x2 -3x+1=0 is quadratic equation in variable x. SOLVING A QUADRATIC EQUATION 1.Factorisation A real number a is said to be a root of the quadratic equation ax2 + bx + c=0‚ if aa2+ba+c=0. If we can factorise ax2 + bx + c=0‚ a 0‚ into a product of linear factors‚ then the roots of the quadratic equation ax2 + bx + c=0 can be found

When a person has enough power in a society‚ it gives them a lot of control over certain things. When they have this control‚ they can have ownership over a person or a thing. By naming someone‚ or something‚ a person gains an unspoken ownership over him or her‚ they are now in control of him or her and it has created a new identity for them and erased their old identity. Power‚ naming and un-naming‚ control and ownership and identity are very important elements in “Mary” and “No
