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:
The rate is greater than 8%
Explanation:
Given
<em>Missing part of question</em>
Required
Is r > 1
We have:
Substitute values for r and I
Divide both sides by 1000
Add 1 to both sides
Take square roots of both sides
Subtract 1 from both sides
Multiply both sides by 100
<em></em>
<em>Hence, the rate is greater than 8%</em>
Explanation:
The adjusting entry is as follows
On January 31
Unearned revenue A/c Dr $3,500
To Magazine subscription revenue A/c $3,500
(Being the unearned revenue is recorded)
The computation is shown below:
= Sale value of annual subscriptions ÷ total number of months in a year
= $42,000 ÷ 12 months
= $3,500
Answer:
It is cheaper to make the units in-house.
Explanation:
Giving the following information:
Make in-house:
Direct material $ 8
Direct labor 24
Overhead 40
Total costs per unit $72
Buying price= $60
<u>We need to determine which option provides the lower cost. Because 40% of overhead will remain constant, we have to take it out of the equation.</u>
<u>Production cost:</u>
Direct material $ 8
Direct labor 24
Overhead= 40*0.6= 24
Total production cost= $56
It is cheaper to make the units in-house.
The calculated present value of the annuity is $915,166.70.
Explanation and Solution:
Annuity is a collection of fixed payments made or earned either at the close or at the beginning of any term such that a significant initial payment or receipt may be turned into a set of comparatively minor payments or receipts. An annuity that lasts indefinitely is called perpetuity.
The formula for the present value of the annuity is given by:
Where;
R = annual payment = $75,000
i = interest rate = 5.25%
P = Present value of annuity
n = number of years = 20 years
P = 
P = $915,166.70
