Answer:
Data mining refers to the ability of an organization to extract relevant information for a large reservoir of data that belong to its users for the purpose of increasing service/product efficiency.
One example of a company that requires data mining for the success of its business is Amazon. Amazon is categorized by many as an online retail giant. Their Customer-Centric approach to doing business is enhanced by their ability to leverage off historical data to reduce the time spent on resolving customer queries and/or complaints.
Generally, there are four basic data mining functions. They are:
- Prediction Function: This function allows for the owner to spot patterns in behavior and use this as a yardstick to predict for forecast other variables that will enable the increment in the quality of value offered/delivered.
- Function Description: This functionality highlights attributes of a set of data in the database
- Classification Function: This is very close to Function Description only that in this case, it helps in the creation of a model that describes the class or concept of data.
- Association Function: This functionality highlights the relationship between data
The above functions cannot be carried out by data query processing or simple statistical analysis because data mining involves the identification of patterns and relationships using algorithms whilst data query refers to the issuance of instructions in search of specific results.

Since the preferred stocks are cumulative in nature, the dividend amount not paid in the current year will be accumulated and paid in the next year.
Preferred dividend to be paid in 2017 = Value of preferred stock x Dividend rate
= (4700 x $50) x 5%
= 11750
Dividend to be paid in 2018 = same as 2017 as no new preferred stock issued
= 11750
Total dividend to be paid in 2018 = Dividend to be paid in 2018 + Dividend to be paid in 2017 – Dividend paid in 2017
= 11750 +11750 -7900
= $15600
Answer:
Interest = $5,834.67
Explanation:
In November 1, the note bears 12 month = 7%
From November 1 to December 31 = 2 month
Hence for 2 month Interest = 2 * 7/12(%) = 1.1667%
Thus, interest = $500,100 * 1.1667%
Interest = 5834.6667
Interest = $5,834.67 approximately.
In team-based environments, the principal may have difficulty determining individual contributions by members. This can create a situation in which an opportunistic employee does little work but takes credit and this is known as adverse selection.
<h3>
What is Adverse selection?</h3>
- In general, the term "adverse selection" refers to a situation in which sellers have knowledge about a certain feature of product quality but purchasers do not, or vice versa. In other words, it is an instance of the use of asymmetric information.
- When one side to a transaction has more in-depth knowledge of the relevant facts than the other, this is known as asymmetric information, also known as information failure.
- Usually, the vendor is the one who has more knowledge. When both parties are knowledgeable, it is said that there is symmetric information.
