In the double-shaded region, we can see all the different combinations of number of pairs of earrings and number of necklaces to sell in order to make a profit. To test that you shaded correctly, check a point in the double-shaded area, and see if it works. It works in all the inequalities.

Using the model to find the solution: It is a simplified representation of the actual situation It need not be complete or exact in all respects It concentrates on the most essential relationships and ignores the less essential ones. It is more easily understood than the empirical i.

It can be used again and again for similar problems or can be modified. Fortunately the probabilistic and statistical methods for analysis and decision making under uncertainty are more numerous and powerful today than ever before.

The computer makes possible many practical applications.

A few examples of business applications are the following: An auditor can use random sampling techniques to audit the accounts receivable for clients. A plant manager can use statistical quality control techniques to assure the quality of his production with a minimum of testing or inspection.

What are the objectives of the study or the questions to be answered? What is the population to which the investigators intend to refer their findings? Is the study a planned experiment i. How is the sample to be selected? Are there possible sources of selection, which would make the sample atypical or non-representative?

If so, what provision is to be made to deal with this bias? What is the nature of the control group, standard of comparison, or cost? Remember that statistical modeling means reflections before actions.

Is the method of classification or of measurement consistent for all the subjects and relevant to Item No. Are the observations reliable and replicable to defend your finding? Are the data sufficient and worthy of statistical analysis?

If so, are the necessary conditions of the methods of statistical analysis appropriate to the source and nature of the data?Absolute Value Equations and Inequalities Absolute Value Definition - The absolute value of x, is defined as there is no solution. The absolute value of something will never be less than or equal to a negative number.

solve each inequality, writing the solution as a union of the two solutions. In probability theory, the expected value of a random variable, intuitively, is the long-run average value of repetitions of the experiment it benjaminpohle.com example, the expected value in rolling a six-sided die is , because the average of all the numbers that come up in an extremely large number of rolls is close to Less roughly, the law of large numbers states that the arithmetic.
