Explanation Given: The number of middle school sports teams are 241 . The circle graph is shown in figure (1), Table (1) Approach: The number of teams represented by each sector can be calculated as, n = ( x × r 100 ) ... ( 1 ) Here, n is the number of team, r is the percentage color of middle school team uniform and x is the total number of middle school team. Calculation: From figure(1), The percentage of black color of middle school team sport uniform is 24 % , the percentage of navy blue color of middle school team sport uniform is 22 % , the percentage of white color of middle school team sport uniform is 20 % , the percentage of gray color of middle school team sport uniform is 17 % , the percentage of maroon color of middle school team sport uniform is 12 % and the percentage of green color of middle school team sport uniform is 5 % . For the black color, Substitute 22 % for r and 241 for x in equation (1), n = ( 241 × 24 100 ) = 58 Similarly for the navy-blue color, Substitute 22 % for r and 241 for x in equation (1), n = ( 241 × 22 100 ) = 53 Similarly for the white color, Substitute 20 % for r and 241 for x in equation (1),

Family of Curves

A family of curves is a group of curves that are each described by a parametrization in which one or more variables are parameters. In general, the parameters have more complexity on the assembly of the curve than an ordinary linear transformation. These…

XZ Plane

In order to understand XZ plane, it's helpful to understand two-dimensional and three-dimensional spaces. To plot a point on a plane, two numbers are needed, and these two numbers in the plane can be represented as an ordered pair (a,b) where a and b are…

Euclidean Geometry

Geometry is the branch of mathematics that deals with flat surfaces like lines, angles, points, two-dimensional figures, etc. In Euclidean geometry, one studies the geometrical shapes that rely on different theorems and axioms. This (pure mathematics) ge…

Lines and Angles

In a two-dimensional plane, a line is simply a figure that joins two points. Usually, lines are used for presenting objects that are straight in shape and have minimal depth or width.

7. [10 marks] Let G = (V,E) be a 3-connected graph. We prove that for every x, y, z Є V, there is a cycle in G on which x, y, and z all lie. (a) First prove that there are two internally disjoint xy-paths Po and P₁. (b) If z is on either Po or P₁, then combining Po and P₁ produces a cycle on which x, y, and z all lie. So assume that z is not on Po and not on P₁. Now prove that there are three paths Qo, Q1, and Q2 such that: ⚫each Qi starts at z; • each Qi ends at a vertex w; that is on Po or on P₁, where wo, w₁, and w₂ are distinct; the paths Qo, Q1, Q2 are disjoint from each other (except at the start vertex 2) and are disjoint from the paths Po and P₁ (except at the end vertices wo, W1, and w₂). (c) Use paths Po, P₁, Qo, Q1, and Q2 to prove that there is a cycle on which x, y, and z all lie. (To do this, notice that two of the w; must be on the same Pj.)
