Answer:
Endogenous factors (variables that can be controlled when performing a model test):
The Wright brothers used the wind tunnel to improve the design of their aircraft's wings.
Exogenous factors (variables that cannot be controlled when performing a model test):
- wind and rain
- air pressure
No one can control the climate.
Answer:
$20,000
Explanation:
For computing the Doug withdrawal amount, first, we have to compute the net income or net loss which is shown below:
Net income/loss = Revenue - expense
= $350,000 - $380,000
= -$30,000
Now Doug share in net loss = Net loss × (his share ÷ total share)
= - $30,000 × (2 ÷ 6)
= - $10,000
We knew that the Doug capital is $30,000 and his share in loss is $10,000
So, its withdrawal amount = $30,000 - $10,000 = $20,000
Answer: 1. Large
2. Abnormal
3. True
Explanation:
1. At any level, a market’s informational efficiency is likely to be stronger when there is a <u>Large</u> number of market participants.
When there is a larger number of participants, this means that there is a large number of people able to acquire and analyse information about securities and the financial markets.
As a result of this, information is more wide ranging and easily available such that they market has very good information efficiency.
2. The potential for a security to generate <u>Abnormal</u> returns is what generates a profitable investment.
When a security is potentially able to generate abnormal returns, there is a chance of making very profitable returns if those returns are higher or lower than estimated. When returns are estimated, these are usually reflected in the market price already because they are expected, when the returns are better or worse than expected though, this means that the prices were wrong therefore giving a chance of a positive gain on the security.
3. True.
Information efficiency is very important in the market. It can mean the difference between the market being manipulated and used for unfair gains and the market being used fairly by all. Information efficiency gives every market player the same Opportunity to find out about a security and act accordingly instead of select people taking advantage of hidden Opportunities.
Answer:
The correct answer is letter "D": The customer service center.
Explanation:
The customer service center is a web attractor that allows customers to self-assist in basic operations or by accessing basic data of their own. Balances, statements, payment history, and recent transactions are among the information consumers can access to in a blink of an eye thanks to this online data feed. In case a piece of information is unclear, this feed usually has direct access to reach a customer service representative for an explanation.
Table/indexed.
Let's look at the three options and see what their advantages and disadvantages are:
Contiguous - In this scheme, the file is stored in contiguous blocks of the disk. It allows for easy random access of the data, but requires a contiguous sequence of blocks large enough to handle the entire file. Since the size of the file specified in this question varies quite a bit over it's lifespan, you're either going to be wasting a lot of space by having an allocation large enough to handle the maximum sized file, or the file will need to be copied whenever it grows and "bumps" into a file that was allocated after it. Because of this, this method is not the best.
Linked - The file is stored as a single, or double linked list of file blocks. This allows for the file to grow or shrink as needed, using only the amount of space needed for the file. Unfortunately, this storage scheme doesn't allow for random access of the file contents and the file can only be accessed sequentially. The question for this problem doesn't specify how the file is being accessed, so as long as random access isn't required, then this would be a reasonable allocation scheme. But I'm assuming that random access will be required, in which case, this scheme isn't ideal.
table/indexed - In this scheme, some disk blocks are used as tables to point to other disk blocks that actually contain the file data. It's almost as fast as contiguous allocation for random access of the file contents, yet allows for the growth and shrinkage of a file like linked allocation. As such, it handles all use cases at a relatively minor cost in total storage required. So this would be the most appropriate allocation scheme since the file access behavior wasn't specified in this question.
