The survey results of the ages of students in the Adult Basic Education Maths classes are shown in the bar graph. Find the median, lower quartile by constructing the ogive of the data. => 15, 44 or 25.8, 20.4 or 21, 36 or 26, 15.8..

Polynomials - An expression of the form in which a i are numbers belonging to some number system and 'n' is a non-negative integer, is called a polynomial. a i are called the coefficients of if a o 0, the polynomial is said to be of degree ..

Notation: Usually a polynomial is denoted by P(x) and if k is any number then P(k) denotes the value of P(x) at x=k. The degree of a polynomial: If a o ? 0, then the polynomial P(x) or f(x) is of degree 'n' i.e., it is the highest power of the variable x in the rational and integ..

Set: A well-defined collection of distinct objects is called a set. Notation of Sets: Capital letters are usually used to denote or represent a set. Representation of Sets: There are two methods of representing a set. (i) Roster Method (ii) Set builder form. Finite an..

Basic Proportionality Theorem - A line parallel to one side of a triangle divides the other two sides into parts of equal proportion. In triangle ABC, a line drawn parallel to BC cuts AB and AC at P and Q respectively. Let the point P divide AB in the ratio of l: m where l and m are natur..

Basic Proportionality Theorem (B.P.T.) will be more useful in the topic 'SIMILARITY'. Division of a line segment into equal parts. Divide a line segment of length 8.4 cm into 5 equal parts. AB = 8.4 cm 1. Draw AB = 8.4 cm and through A draw another line AX at an acute angle to AB. 2. With..
