linear regression In statistics‚ linear regression is an approach to model the relationship between a scalar dependent variable y and one or more explanatory variables denoted X. The case of one explanatory variable is called simple linear regression. For more than one explanatory variable‚ it is called multiple linear regression. (This term should be distinguished from multivariate linear regression‚ where multiple correlated dependent variables are predicted‚[citation needed] rather than a single

Uniform linear acceleration Introduction This topic is about particles which move in a straight line and accelerate uniformly. Problems can vary enormously‚ so you have to have your wits about you. Problems can be broken down into three main categories: Constant uniform acceleration Time-speed graphs Problems involving two particles Constant uniform acceleration Remember what the following variables represent: t = the time ; a = the acceleration ; u = the initial speed ; v = the final

theory of justice which implies that punishment has to be proportionate to the crime that has been committed. An eye for an eye‚ limb for limb is barbaric examples of such justice. REFORMATIVE: Reforming or changing the criminal’s mindset is the need of the hour. But unfortunately these so called reforms only takes place after the crime has been committed so that the offender doesn’t commit the mistake again.

The purchase price of each fabric is also shown in Table 1. MANAGERIAL REPORT I. - Develop a Linear Programming Model that can be used to schedule production for the Southern Textile Mill‚ and at the same time to determine how many yards of each fabric must be purchased from another mill. The model should be clear and complete.

business environment. The prospects of American Semiconductor’s products are frequently reviewed‚ as with any organization‚ and the company’s strategy is constantly analyzed. Therefore‚ the business decided to relinquish their debt financing and acquire equity financing; a decision that is not advantageous for a privately owned organization unless the owner wishes to give up total control of the business. Currency is the necessary means for every person to achieve something new. To begin business

requires just 1 gallon per acre. What is the maximum profit he can make? SOLUTION TO PROBLEM NUMBER 1 let x = the number of acres of wheat let y = the number of acres of barley. since the farmer earns $5‚000 for each acre of wheat and $3‚000 for each acre of barley‚ then the total profit the farmer can earn is 5000*x + 3000*y. let p = total profit that can be earned. your equation for profit becomes: p = 5000x + 3000y that’s your objective function. it’s what you want to maximize the constraints
