Non-convex Sets
We know that the feasible solution of an LPP is a set. This set (If it is finite non-empty) is convex for any L.P.P. There are four types of feasible region normally we g..

There are three methods to find mean for a frequency distribution. (i) Direct method: where x is the mid-interval f is the frequency M is the mean (ii) Short-cut method: where A = assumed mean d = x - A (iii) Step-deviation method: where i = class size We illustrate each of these..

This Tutor Vista is GREAT! loved this session, it helped me heaps.
Tutor are so organized and neat with their teachings. She set up everything that made the problems more understandable by showing them in such a simple manner, I feel I could really learn from them and pertain it to my class! :)
My son really liked the tutors approach! thanks so much he left the computer feeling postive and confident about his test tomorrow. and that make us (mom and dad) happy!!!!!!
You are an amazing tutor. So knowlegeable and patient. Very clear in explanations, 2 thumbs up -kelly
