...purpose of comparison operators and logical operators. The purpose of a comparison operator is to test some kind of relationship between two entities examples are >, <, ==, !=, etc 4. How does a comparison performed on numeric data differ from a comparison performed on string data? There are commonly used interchangeably, and the distinction between them is a small one. Comparison to" should be used when comparison is made between specific people, things, or other instances. 5. How does Visual Basic compare the Text property of a text box? When you compare the Text property of a text box with another value the Text property behaves like a variant. Visual Basic compares one text box to another as strings and compares a text box to a numeric variable or constant with a numeric compare. You can force a numeric comparison on a Text property by using the Val function. 6 . Why would it be useful to include the ToUpper method in a comparison? When comparing strings, the case of the characters is important. An uppercase “Y” does not compare equal to a lowercase “y”. Since the user may type a name or word in either uppercase or lowercase or a combination of the two, we must check all possibilities. The easiest way is to use the string function Ucase or Lcase, which returns the uppercase or lowercase equivalency of a string, respectively. 7. Name the types of items that can be used in a comparison. The conditions to be tested can be formed with numeric variables and constants...

Determine the required number of pi terms 4. Select a number of repeating variables 5. Form a pi term by multiplying one of the non repeating variable by the product of repeating variables each raised to an exponent that will make the combination dimensionless 6. Repeat step 5 7. Check all the resulting pi terms 8. Express the final form as a relationship among the pi terms and think about what it means Recapitulation 1. A base quantity is a property that is defined in physical terms by two operations: a comparison operation, and an addition operation. The comparison operation is a physical procedure for establishing whether two samples of the quantity are equal or unequal; the addition operation defines what is meant by the sum of two samples of that property. 2. Base quantities are properties for which the following concepts are defined in terms of physical operations: equality, addition, subtraction, multiplication by a pure number, and division by a pure number. Not defined in terms of physical operations are: product, ratio, power, and logarithmic, exponential, trigonometric and other special functions of physical quantities. 3. A base quantity can be measured in terms of an arbitrarily chosen unit of its own kind and a numerical value. 4. A derived quantity of the first...

...Press. Answer to Nathan: (6/26) Hi Nathan, I agree with you when you say "an expression is a mathematical "phrase". " In most cases it stands for a single element. 3x + 1 is an example of an expression. The expression means that its value three times the value of x, plus 1. An expression can also be a single number or variable, since those have a numerical value. Unlike in the case of an equation, an expression is never true or false, but just has a numerical value. Are the properties used to solve inequalities the same as those used to solve equations? Explain your answer. (6/27) The properties to solve inequalities are NOT exactly the same as the properties to solve equations. But, the properties to solve equations ARE exactly like those used to solve inequalities. Inequalities have an exclusive property while solving because of the character of the comparability of the inequality. The exclusive property is the function of multiplying or dividing by a minus integer. By multiplying or dividing by a minus integer, the comparability of the inequality is changed. In case rendered the same, this would develop a wrong expression. The additional property in solving inequalities is that whenever multiplying or dividing by a...

...such as tendency, distribution, and variables. A examples of this would be if a company wanted to find out what type of bonus employees prefer. Descriptive statistics are used to explain the basic properties of these variables. One descriptive statistics that is used to explain the basic properties of variables is Mean, Median, and Modes. These terms all would be descriptive statistics for the above example by describing the central tendency in different ways. The mean would reflect the average answer that is given. The Median would provide the answer that is the central or middle range answer. The mode would be the answer that was given the most often. A second descriptive statistic that is used to explain the basic properties of variables is Tabulation. This refers to the orderly arrangement of data in a table or other summary format. When the tabulation process is done by hand, the term tallying is used. Simple tabulation tells how frequently each response or bit of information occurs. A third descriptive statistic used to explain the basic properties of variables is Cross Tabulation. This techniques is used for addressing research questions involving relationships among multiple less than interval variables. One key factor in interpreting a cross tabulation table is comparing the observed table values with the hypothetical values that could result from pure chance. A fourth descriptive statistic used to explain the basic properties...

...| Purpose In this project, a database management system will be implemented to make the self-ordering easier. The users for this program will be used for customers in various restaurants. It will take a customer’s order, total it, and give them an amount. The system will instruct the customer to enter the correct amount. If the amount is not enough, the system will instruct them to enter more money. If it is too less, however, the system will them issue out change. Use of Visual Basics Visual Basic for Applications (VBA) will be used because it is a programming language built right into many Microsoft programs. This language is built on the Basic programming language made popular by PCs over the past 25 years. VBA shares similarities with other Windows implementations of the Basic language, such as Visual Basic. If you are familiar with programming in a different language (including using macros), you can quickly get up to speed with VBA. There are a few terms you should know before you start programming in VBA: * Procedure. A section of programming code, designed to accomplish a specific task, which your program statements can use throughout your program. There are two types of procedures: functions and subroutines. * Function. A procedure that returns a value after it completes its task. When called, functions typically appear on the right side of an equal sign in an expression. * Subroutine. A procedure that does not return a value after it completes its...

...Preexperimental design and quasi-experimental design. c) History and maturation. d) Random sampling, randomization, and matching. e) Environmental variables and extraneous variables. a) Validity is defined in experimentation as whether a measure accomplishes what we think previously or not. There are different types of validity, but the two main varieties are internal and external validity. Internal validity answers the question- do the obtained results have a relationship with what we demonstrated in the experiment? Does the experiment show the real cause of what we draw in the conclusion? It is judged by how well it meets the seven internal validity threats. External validity explain if the observed causal relationship can be generalize among persons, settings, and times. It concerns with the relationship between experimental treatment and other factors. It is used when we have larger population. b) Preexperimental designs are used to control contamination of the relationship that exists between independent and dependent variables. This design is very weak because it fails to control the threats to internal validity or to provide comparison groups that are truly equivalent. Quasi-experimental designs are field experiments that are more advanced than preexperimental. They have control over some of the variables. Using this experiment, we cannot know when or to whom to expose experiment treatment. Also, these designs are not classify as true experiments either...
