What is the relationship between the speed of light and the index of refraction of a transparent substance?

In the radical expression $\sqrt[5]{125}$ what is the index? What is the radicand?

The price of computers has fallen substantially over the past two decades. Use this drop in price to explain why the Consumer Price Index is likely to overstate substantially the cost-of-living index for individuals who use computers intensively.

This will happen if you try to use an index that is out of range for a list. a. A ValueError exception will occur. b. An IndexError exception will occur. c. The list will be erased and the program will continue to run. d. Nothing—the invalid index will be ignored.

What is the relationship between refraction and the speed of light?

In order to light an LED with a 12V supply, what resistor value is needed?

If a short-term investment in available-for-sale securities costs $6,780 and is sold for$7,500, how should the difference between these two values be recorded?

Look at the following statement:
numbers = [10, 20, 30, 40, 50]
a. How many elements does the list have?
b. What is the index of the first element in the list?
c. What is the index of the last element in the list?

Consider the weighted voting system {60: 4, 56, 58}. a. Compute the Banzhaf power index for each voter in this system. b. Voter B has a weight of 56 compared with only 4 for voter A, yet the results of part a show that voter A and voter B both have the same Banzhaf power index. Explain why it seems reasonable, in this voting system, to assign voters A and B the same Banzhaf power index.

How long does it take light to travel from the Sun to Venus?

Your investment client asks for information concerning the benefits of active portfolio management. She is particularly interested in the question of whether active managers can be expected to consistently exploit inefficiencies in the capital markets to produce above-average returns without assuming higher risk.

The semistrong form of the efficient market hypothesis asserts that all publicly available information is rapidly and correctly reflected in securities prices. This implies that investors cannot expect to derive above-average profits from purchases made after information has become public because security prices already reflect the information’s full effects.

a. Identify and explain two examples of empirical evidence that tend to support the EMH implication stated above.

b. Identify and explain two examples of empirical evidence that tend to refute the EMH implication stated above.

c. Discuss reasons why an investor might choose not to index even if the markets were, in fact, semistrong-form efficient.

Indicate whether each of the following characteristics relates to managerial accounting (MA) or financial accounting (FA):
