lines in real life situations

>There are many daily life situations where n is very large and p is very small. In such situations, the Poisson distribution can be more conveniently used as an approximation to binomial distriburtion which may prove cumbersome for large values of n. This is called Po..

Mathematical Formulation of Linear Programming Problems - There are mainly four steps in the mathematical formulation of linear programming problem as a mathematical model. We will discuss formulation of those problems which involve only two variables. Identify the decision variables and assign sym..

In real life an object which is moving over a horizontal surface does not continue with constant velocity when the accelerating force is removed. Instead the object slows down and eventually stops. The deceleration is caused by a frictional force between the object and the..

They evolved 3300 to 3500 million years ago. They were like present day cyanobacteria and could release O 2 into the atmosphere because they used water as the reagent. Thus, the whole reducing atmosphere changed to an oxidising atmosphere. Autotrophs are said to have arisen much later in the prim..

In a Rectangular Cartesian System of coordinates the position of a point in a plane is determined by an ordered pair whose elements give the distances from the intersecting straight lines at right angles to each other. These lines are called the axes. The vertical line..

of parallelograms seen in the previous chapter. We find that the line segment joining the mid points of any two sides of the triangle is parallel to the third side and is equal to half of it. We prove this in the mid point theorem. Inequalities (Triangles) We have studied so far about equ..

Guidelines - The story is in various stages. The innocence of the narrator is seen clearly. Observe the optimism of the young girl. Make a note of the many changes and experiences the girl goes through. Though the entire incident seems traumatic, observe that the narrator does not lose hope. Read s..

Transversal - A transversal is a line that intersects two or more lines at distinct points. In the figure given below, XY is a transversal. (i) The four pairs of angles 1 and 5, 2 and 6, 4 and 7, 3 and 8 are called corresponding angles (the corresponding angles are similarly ..

Question: The mirror view of life is difficult to accept. Do you agree with the statement? Substantiate your answer with examples from the poem. Answer: The mirror does not lie, it gives only the real or true image of a person standing before it. It has no preconce..

In the previous chapters we studied the motion of a body moving with uniform speed in a straight line and also learnt to calculate the distance traveled by a body in any given time. We then observed that the bodies do not always move with uniform speed and an external unbalanced force is ..
