What are some differences in the analysis for a replacement project versus that for a new expansion project?

Explain why sunk costs should not be included in a capital budgeting analysis but opportunity costs and externalities should be included. Give an example of each.

Discuss the following statement: All else equal, firms with relatively stable sales are able to carry relatively high debt ratios. Is the statement true or false? Why?

A glass of water contains a teaspoon of dissolved sugar. After a while, the water evaporates, leaving behind sugar crystals. The entropy of the sugar crystals is less than the entropy of the dissolved sugar because the sugar crystals are in a more ordered state. Why doesn't this process violate the second law of thermodynamics? (a) Because, considering what happens to the water, the total entropy of the universe also decreases. (b) Because, considering what happens to the water, the total entropy of the universe increases. (c) Because the second law does not apply to this situation.

What are the four key assumptions examined in specification analysis in the case of simple regression?

Using mesh analysis, find the voltage $V$ across the current source in the figure.

What are the representative elements? In what region(s) of the periodic table are these elements found? In what general area of the periodic table are the metallic elements found? In what general area of the table are the nonmetals found? Where in the table are the metalloids located?

Write each premise in symbols, and then in the final part, give a conclusion that yields a valid argument.

Let $p$ be "one is able to do logic," $q$ be "one is fit to serve on a jury," $r$ be "one is sane," and $s$ be "he is your son." (a) Everyone who is sane can do logic. (b) No lunatics are fit to serve on a jury. ($\text{}$c) None of your sons can do logic. (d) Give a conclusion that yields a valid argument.

Find the logic function corresponding to the truth table of figure in the simplest sum-of-products form.

The local G-statistic can be used as a tool for hot spot analysis. Why?

Where on the blank outline of the periodic table do elements that meet the following descriptions appear? (a) Elements with the valence-shell ground-state electron configuration $n s^2 n p^5$ (b) An element whose fourth shell contains two $p$ electrons (c) An element with the ground-state electron configuration $\left[\right.$ Ar] $4 s^2 3 d^{10} 4 p^5$

Summarize the characteristics of pollen and spores that make their identification and analysis useful in crime scenes.

The following propositions are given. p: The train leaves from gate 2. q: The train leaves from gate 8. r: The train does not leave today. a. Write a sentence, in words, for the following logic statement: $p \Rightarrow(\neg r \wedge \neg q)$. b. Write the following sentence as a logic statement using p, q, r and logic notation: 'The train leaves today if and only if it leaves from gate 2 or from gate 8.'

A vertical column of elements in the periodic table is called a(n).
