The LPP is a class of mathematical programming where the functions representing the objectives and the constraints are linear. Optimisation refers to the maximisation or minimisation of the objective functions.
The following are the characteristics of this form.
• All decision variables are non-negative.
• All constraints are of = type.
• The objective function is of the maximisation type.

What is The model y A plus Bx is a?
It is a linear model.
Is it true that the y-intercept in the linear regression model is always 0?
It could be any value
How would you interpret the findings of a correlation study that reported a linear correlation coefficient of 1.67?
There is not enough information to say much. To start with, the correlation may not be significant. Furthermore, a linear relationship may not be an appropriate model. If you assume that a linear model is appropriate and if you assume that there is evidence to indicate that the correlation is significant (by this time you might as well assume anything you want!) then you could say that the dependent variable increases by 1.67 for every unit change in the independent variable - within the range of the independent variable.
Example of a real life linear function?
Linear functions are used to model situations that show a constant rate of change between 2 variables. For example, the relation between feet and inches is always 12 inches/foot. so a linear function would be y = 12 x where y is the number of inches and x is the number of feet. y = 24 x models the number of hours in any given number of days {x}. Business applications abound. If a cell phone company charges a start-up fee of $50 and then $.05 for every minute used, the function is y = .05 x + 50.
What is the difference between a verbal model and a algebraic model?
The differnce between a verbal model and a algebraic model is that a verbal model is an equation written in words and a algebraic model is solving the equation from the verbal model.
Characteristics of linear programming model?
Linear programming models involve optimizing an objective function subject to linear constraints. They assume additivity and proportionality in the relationships between decision variables and the objective function. Linear programming models also require non-negativity constraints on decision variables.
What is linear programming used for?
Linear Programming is used for determining a way to find the best solution or outcome for a given mathematical model represented as a linear relationship.
Explain what linear programming is and what the various models are?
the sequential flow of processes usually linear and its has two types which are: Waterfall and Prototyping Model
What is meant by mathematical model in particular linear programming model?
A mathematical model is the representation of a relationship or state or phenomenon in a mathematical form using control variables.
Advantages and limitations of linear programming as a managerial decision making model?
It takes out the personal angle in decision making.
When formulating a linear programming model on a spreadsheet the measure of performance is located in the target cell?
Yes, in a linear programming model on a spreadsheet, the measure of performance is typically located in the target cell, which is often the cell that you are trying to either maximize or minimize by changing the decision variables. The goal is to optimize the measure of performance by finding the best values for the decision variables based on the constraints of the model.
Can a linear programming problem have multiple optimal solutions?
When solving linear prog. problems, we base our solutions on assumptions.one of these assumptions is that there is only one optimal solution to the problem.so in short NO. BY HADI It is possible to have more than one optimal solution point in a linear programming model. This may occur when the objective function has the same slope as one its binding constraints.
What has the author Ross Kingwell written?

What is a linear model?
A model in which your mother.
which characteristics of a data set makes a linear regression model unreasonable?
A correlation coefficient close to 0 makes a linear regression model unreasonable. Because If the correlation between the two variable is close to zero, we can not expect one variable explaining the variation in other variable.
What is The model y A plus Bx is a?
It is a linear model.
What do you know about a linear model from the correlation coefficient?
It's a measure of how well a simple linear model accounts for observed variation.
