TRUE/FALSE – clearly indicate your response.
1. Sensitivity analysis is the analysis of the effect of parameter changes on the optimal solution.T .

2. The sensitivity range for an objective function coefficient is the range of values over which the current optimal solution (product mix) will remain optimal. T .

3. The sensitivity range for a right-hand-side value in a constraint is the range of values over which the quantity values can change without changing the solution variable mix, including slack variables. T .

4. The terms reduced cost, shadow price, and dual price all mean the same thing. F .

5. Sensitivity analysis can be used to determine the effect on the solution for changing several parameters at once. F .

6. A negative shadow price indicates that the objective function decreases when the right hand side of a constraint increases. T .

7. For a profit maximization problem, if the allowable increase for a coefficient in the objective function is infinite, then profits are unbounded. T .

MULTIPLE CHOICE – clearly indicate your response.
1. For a linear programming problem, assume that a given resource has not been fully used. In other words, the slack value associated with that resource constraint is positive. We can conclude that the shadow price associated with that constraint: A. will have a positive value.

B. will have a negative value.
C. will have a value of zero.
D. could have positive, negative, or zero value.D .

...Santoro, A. (2004). “Manipulatives: A Hands-On Approach to Math.” Principal, 84 (2), (28-28).
This article speaks about the importance and significance of the use of manipulatives in the classroom, specifically in the subject of math. Manipulatives have proven to be valuable when used in a math class and are even more valuable to the children when they are young, and are learning new math concepts. Students are able to physically...

ANALYSIS
Physics has a lot of topics to cover. In the previous experiments, we discussed Forces, Kinematics, and Motions. In this experiment, the focus is all about Friction. Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other. There are several types of friction like fluid friction which describes the friction between layers of a viscous fluid that are moving relative to each other; dry friction which...

The case between Beauty and Stylish involves concept of a valid contract, pre-contractual statements, express term and misrepresentation.
A valid contract is established between Beauty and Stylish when an offer is accepted and there is intention for both parties to create legal relations. An offer refers to the expression of willingness of the offerer to be contractually bound by an agreement if his or her offer is properly accepted. It has to be clear and certain in terms. It must also...

Four Decades of the Defence of
Australia: Reflections on Australian
Defence Policy over the Past 40 Years
Hugh White
The serious academic study of Australian defence policy can be said to have
begun with the publication of a book by the SDSC’s founder, Tom Millar, in
1965. The dust jacket of that book, Australia’s Defence, posed the following
question: ‘Can Australia Defend Itself?’ Millar thus placed the defence of Australia
at the centre of his (and the SDSC’s) work...
