Capital Budgeting: Math Case Study (Answering questions)... From the given data, it can be seen that Project ‘p’ has a higher NPV as compared to Project ‘q’. Hence, if NPV is chosen as the criterion, Project ‘p’ must be preferred. However, it is also seen that Project ‘q’ has a higher IRR. Thus, form IRR point of view ‘q’ is the preferred project. Overall, there is a large difference between NPVs of the two projects while there is a smaller difference between their IRRs. Hence, Project ‘p’ should be selected over Project ‘q’. Moreover, IRR ranking is misleading here because the base investment (initial cash outflow) in the two projects is not the same. The cash outflow in Project ‘p’ ($200) is twice that of project ‘q’ ($100). Hence, it would not be appropriate to compare the two projects...

Solve the questions... Session hijacking can be mitigated by making changes to the server – client credential process. Describe one of the methods. Session hijacking canbe conducted in means of turning the source-routine off. In this scenario, the attacker is allowed to have access at point A on the network. If source-routing is turned off, the hacker can use "blind" hijacking, where it manipulates two machines in order to guess to take over the control. Hence, the hacker can send a command, but can never see the response. However, setting permanent password from the hacker’s standpoint can be very huge vulnerability. 2) The user is a critical part of phishing prevention. What are two elements that might give away an attempt to pose as a financial site...

College Math Math Problem...**Math** Problem a) I constructed the first linear function based on the municipal solid waste data for 1970 and 1997 and the second linear function based on the data for 1980 and 1997. A dependent variable is the annual production of municipal solid waste in million tons. An independent variable is the number of years after 1960.
Based on the municipal solid waste data from the graph, I received such numbers for independent and dependent variables for the models.
Model 1
Model 2
Dependent Variable

Model 1:
121 = a + b*10
217 = a + b*37
The solution is a=85.4, b=3.56. Therefore, the first linear function is:
Annual MSW =...

Math Questions...**Question** No A problem that we may need to **solve** in business:- Another major problem we commonly face in business is of determination of the production quantity, i.e. what quantity should we produce? Its common answer is that at least we should produce the quantity at which we meet all of our costs which is called the “Break Even Quantity/ volume”.
At the breakeven point business fulfills all of its production costs (fixed cost and all types of variable costs) and is neither generating any profit nor facing any loss. At this point total revenue of firm is equal to its total costs. Normally break even is calculated by using the equation TR=TC, to which we **solve** using trial and error method by using different production quantities... . It is a...

Math operation questions...DQ Rational expression is very much similar to fraction and therefore doing operations—adding, subtracting, multiplying, and dividing—with rationalexpressions is similar to doing operations with fractions. When we multiply rational expressions, we multiply numerators and multiply denominators. For dividing by a rational expression, we multiply by its reciprocal. For adding and subtracting rational expressions, we take least common multiple, (LCM) of denominators so as to have same denominator in every expressions and than we add (or subtract) the numerators. Both fractions and rational expressions follow the same rule for doing operations. Therefore, understanding how to work with one kind of problem can help understand how... Rational...

Solve the questions...Task: **Questions** on the Story of Stuff The golden arrow in the story has been described by the narrator, Anne Leonard, in an allegorical manner talking of an arrow being protected by the government. The golden arrow of consumption compels us to think that we are not fashionable the way we are. Therefore, we go buy new hats, clothes and other materials which are harmful to our lives, yet attractive. It is accomplished through the support of the government, for instance, in this case Annie talks of George Bush the then president instructing people to buy bulk of goods (Leonard).

Solve the questions...effects of atrazine and DES were related in rats to humans. The fact that smaller creatures are able to simulate and identify potential effects of pesticide exposure on humans is most intriguing.
Overall **Questions**
Discuss the pros and cons of animal testing. Do you think that testing on animals is justified?
Animal testing is an integral part of the product and drug trails before their commercialization. The benefits of testing animals are the fact that it acts as a prototype through which the effects of the drug or product on human life can be simulated. The value of human life cannot be compared with that of animals, for this reason these product or drug trials cannot be tested on humans directly. The research helps...

Elementary Math Questions...Elementary **Math** Discussion **Questions** At which age are manipulatives no longer needed in the room? Manipulatives are important in that they aid learners in understanding mathematic concepts better. They are especially important for young learners as they offer visual solutions to mathematical concepts that may not be obvious to a young mind. However, on acquiring mental skills of understanding the concepts, use of manipulatives should be stopped. There is no particular grade to stop using manipulatives. Their use should be as long as this may help the students understand concepts of interest.

Math questions...are, on one hand, the person being asked may be readily and psychologically conditioned to consider the importance of tutorial in any case without paying due regard on situations it is most needed, and on the other, he or she may find that passing students make no significant difference from the failing ones. So the ambiguity of meanings attached to the **question** might cause results out of an erroneous understanding that tutorial is actually a necessity and the query sounds as if no second thoughts or further analysis is required.
Conclusion
It is quite obvious how the application of suspect samples in the first problem is demonstrated through an ad statement. Likewise, the second exercise consists of a biased...
