linear relation between two variables

Random Variable and Probability Distribution - If is often very important to allocate a numerical value to an outcome of a random experiment. For example consider an experiment of tossing a coin twice and note the number of heads (x) obtained. Outcome : HH HT TH TT No. of heads (x) : ..

If is often very important to allocate a numerical value to an outcome of a random experiment. For example consider an experiment of tossing a coin twice and note the number of heads (x) obtained. Outcome : HH HT TH TT No. of heads (x) : 2 1 1 0 x is called a random variable, wh..

The mathematical models which tells to optimise (minimize or maximise) the objective function Z subject to certain condition on the variables is called a Linear programming problem (LPP)...

Types of linear systems Gauss-Jordan elimination, Gauss-Jordan method Vectors and vector addition Geometrical solution sets of systems of equations Rectangular matrices to row echelon form Matrix multiplication Inverse to a square matrix Determinants of 2 by 2..

Let the length of the rod increase to 'l 2 ' . Increase in length = (l 2 -l 1 ) = l Rise in temperature = (t 2 -t 1 ) 0 c = t. The ratio of increase in length to its original length per every degree rise in temperature is known as ' the coefficient of linea..

Let light travel from air to medium 1. If c and v 1 are the velocities of light in these media, the refractive index of medium 1 with respect to air, or the absolute refractive index of medium 1 is given by Similarly, when light travels from air to medium 2, we can write Dividing equation..

The graphical method is applicable to solve the LPP involving two decision variables x 1 , and x 2 , we usually take these decision variables as x, y instead of x 1 , x 2 . To solve an LPP , the graphical method includes two major st..

A relation becomes a function only if _______. => for every input, there are fixed number of outputs or for every input, there is exactly one output or for every input, there are two outputs or for two inputs, there is exactly one output..

Relation - Consider the following sentences:Consider the following sentences: 42 is a multiple of 6. Line l is parallel to line m. 10 is greater than 7. In each case the first element is related to the last element by the relation in italics. The two elements..
