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..

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..

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..

A school anniversary function had an attendance of 208 people. How many adults and students attended the function, if the ratio of adults to students was 4 to 9? => 76 adults, 132 students or 64 adults, 144 students or 144 adults, 64 students or Non..

Which of the following basic functions are bounded both above and below? => f ( x ) = 3 + 1 1 + e - x or f ( x ) = 3 · e x or f ( x ) = ( x - 3) 3 or f ( x ) = x 2 - 4..

Objective Function: The Objective Function is a linear function of variables which is to be optimised i.e., maximised or minimised. e.g., profit function, cost function etc. The objective function may be expressed as a linear expression. Constraints: A linear equation represents a s..
