Let's say we have the following relation defined on the set {0,
1, 2, 3}:
{ (0, 0), (0, 2), (2, 0), (2, 2), (2, 3), (3, 2), (3, 3) }
- Please answer the following 3 questions about this relation. (The
relation will be repeated for each question.) Is this relation a
function? Why or why not?
- What are the three properties that must be present in an
equivalence relation? Please give the names of the three properties...

Let S = {0,1,2,3,4,5,6,7,8}. Test the following binary relation
on S for reflexivity, symmetry, antisymmetry, and transitivity. xρy
if and only if x+y = 8.
Is ρ an equivalence relation?
If we change the relation to x ρ y if and only if x+y 6 8 how
will the cardinality of ρ change? Give a detailed explanation.

Give a plausible example of a three-variable research problem in
which partial correlation would be a useful analysis. Define X1,
X2, and Y. Make sure that you indicate which of your three
variables is the "controlled for" variable ( X2). What results
might you expect to obtain for this partial correlation, and how
would you interpret your results (e.g., spurious correlation,
mediation, moderation, and so on)?

How do I solve this using excel: A technician services mailing
machines at companies in the Phoenix area. Depending on the type of
malfunction, the service call can take 1.2, 2.4, 3.6, or 4.8 hours.
The different types of malfunctions occur at the same
frequency.
If required, round your answers to two decimal places.

(a). State TWO contrasts between Pure Project
Teams and Matrix Project Teams. Give an example of each.
3(b). The following data relates to the activities required for
a project. Since exact duration for each activity is not known for
certain, three time estimates were made, namely: - the optimistic,
most likely and pessimistic time estimates. The precedence
relationships are also shown in the data below. You will need to
analyze this problem using what you learned in Chapter 18 of...

Consider the following set of requirements for an airline
database that is used to keep track of flights, passengers,
employees etc. for an airline. You will be graded not only on the
correctness and completeness of the design but also on its
quality.
1) It is important to keep track of
each passenger's name, address, phone number and meal preference
(values could be vegetarian, sea-food, italian, anything). At
times, it...
