P(x) = 300 — 4x. The cost function is c(x) = 500 + 28x where x is the number of units produced. Find x so that the profit is maximum. Question: 1) Find the value of x. 2) In using regression analysis for making predictions what are the assumptions involved. 3) What is a simple linear regression model? 4) What is a scatter diagram method?

3 Introduction to Linear Programming The development of linear programming has been ranked among the most important scientific advances of the mid-20th century‚ and we must agree with this assessment. Its impact since just 1950 has been extraordinary. Today it is a standard tool that has saved many thousands or millions of dollars for most companies or businesses of even moderate size in the various industrialized countries of the world; and its use in other sectors of society has been spreading

2011‚ one US dollar was equivalent to 0.7749 Euros. A linear equation of a function‚ E‚ which converts US dollars (D) to Euros (E) would be E = 0.7749D You would just put the number of dollars in for "D" and multiply by 0.7749 and this will give you the number of Euros you would get for your US dollars. This is a "real world application" of a linear function. Cell Phones Just about everyone has a cell phone‚ and most rate plans are a linear function of some kind. Let’s take a look at a basic example

Why it is difficult for researchers to isolate specific causes of child behaviour - using two of your own examples. How is the term “correlation” a solution to this problem? It is difficult for researchers to isolate specific causes of child behaviour because each child’s environmental settings and values are different from one to another. Most scientists agree that genes have some influence over general intelligence and special aptitudes in such activities as athletics‚ mathematics‚

Linear Thermal Expansion The term thermal expansion refers to the increase in size of an object as that object is heated. With relatively few exceptions‚ all objects expand when they are heated and contract when they are cooled. Perhaps the most important exception to this rule is water. Water contracts as it cools from its boiling point to about 39.2°F (4°C). At that point‚ it begins to expand as it cools further to its freezing point. This unusual effect explains the fact that ice is less dense

Newton’s Laws‚ linear momentum‚ and kinetic energy. Principles In this experiment you will study a collision where a moving object strikes and sticks to an initially motionless object. When the colliding objects stick together the collision is said to be completely inelastic. The net momentum of the system should not change‚ but the net kinetic energy of the system will decrease. The amount of kinetic energy left after the collision can be predicted using conservation of momentum. Linear momentum

dimensions of disability (Reeve‚ 2002). Also the concept of disability is not linear (Reeve‚ 2002). People can be disabled when completing one task yet not disabled when completing another (). For example a deaf student may be disabled when asked to listen to a cd and write down how it makes them feel but not if they are required to look at a picture and write down how that makes them feel. So treating disability as a linear dichotomy is to
