there are 2 buses and 3 trains by which one can travel from city x to city y. what is the probability of travelling by train?

There are 2 buses and 3 trains by which one can travel from city X to city Y. What is the probability of travelling by train? => 2 5 or 1 h..

So far we have learnt how to construct a mathematical model for a linear programming problem. If we can find the values of the decision variables x 1 , x 2 , x 3 , ..... x n , which can optimise (maximize or minimize) the objecti..

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 a..

A linear equation represents a straight line. Limited time, labour etc. may be expressed as linear inequations or equations and are called constraints. e.g., If 2 tables and 3 chairs are to be made in not more than 10 hours and 1 table is made in x hours whi..

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. 1. Identify the decision variables and assign symbols x and ..

(1) Mark class intervals on X-axis and frequencies on Y-axis. (2) The scales for both the axes need not be the same. (3) Class intervals must be exclusive. If the intervals are in inclusive form, convert them to the exclusive form. (4) Draw rectang..

A train is traveling at an average speed of 100 miles per hour. Which of the graphs represents the distance traveled by the train with respect to time? => Graph 2 or Graph 3 or Graph 1 or Graph 4..

A truck leaves at 9:00 A.M. from city X to go to city Y. The line graph represents the distance traveled by the truck, with respect to time. The distance between the two cities is 150 km. Find the time taken by the truck to go to..

A train reaches its maximum speed during the first 10 minutes of its journey and it continues to travel at this speed for the next 15 minutes. It then decelerates to 0 mph during the last 5 minutes of the journey. Choose a graph that shows the speed of the train during..

Arthur traveled by a train which left City-A at 7:30 a.m. and reached City-B at 6:30 p.m. Find the duration of his journey. => 10 hours 30 minutes or 10 hours or 11 hours or 11 hours 30 minutes..
