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.

Answer:
Market price; Equilibrium price
Explanation:
The equilibrium price is the market price where the quantity of goods supplied is equal to the quantity of goods demanded. This is the point at which the demand and supply curves in the market intersect. It become hard to reach equilibrium price and quantity when customers infer the quality of a product by its price cos that will inform their purchasing decision.
The current value of the payment which is $1000 will be:
A=P(1+r/100)^-n
P=1000
r=5 %
n=1
A=1000(1+5/100)^-1
A=1000/1.05
A=$952.38
The first payments of $1000 is worth $952.38 today. The value of the second $1000 is worth:
A=1000(1+0.05)^-2=907.02
today
Answer:
Consider the following explanations
Explanation:
a. The whole argument is based on the controlling of different factors such as age, education and occupation among males and females. Now, this is very subjective how they have controlled occupation. For e.g. – Which all occupation they have considered for as stressful job, which all jobs they have considered as physical tiring jobs. Working in a refinery may be physical tiring job but then working in IT Company can also be tiring.
Therefore since there are lot of factors at play apart the one considered to calculate ratio’s we can say that these differential percentage points can always be more than or less than of what presented in question.
b. The same logic has to be applied to (b) as well. When we say that discrimination account for less than 8 percent of differential we implied to say that occupation nature may have more than 12 percent of differential. Now, if you use above logic and applied from occupation point of view.
