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 segment margin is obtained by deducting the common fixed costs that have been allocated to a segment from that segment's contribution margin
Explanation:
Segment margin is referred to the net profit or the net loss that a particular segment of a business makes. Segment margin is used to know segments that are performing well.
It is also used to know the long-run profitability of a particular segment as it shows the margin that is available after the cost has been covered by a segment.
Based on the above illustration, the statement that isn't true will be "the segment margin is obtained by deducting the common fixed costs that have been allocated to a segment from that segment's contribution margin".
This is false as segment margin is gotten after the traceable fixed costs of a segment has been subtracted from the contribution margin of that particular segment.
Answer:
57.07 months.
Joseph must decide whether the 57th payment was $1,327, or he can pay a 58th payment of just $92.
Explanation:
The easiest way to calculate a monthly payment is using a payment calculator:
- principal = 59,000
- n = 60
- APR = 7.6%
Monthly payments = $1,185.04
Since Joseph will pay an extra $50 each month, his payment = $1,235.04
By paying that extra amount Joseph will reduce his payments by almost 3 months to 57.07 months
After the 57th payment, Joseph' balance = $91.43, so he can decide to pay a little on the 57th payment or just pay $92 next month.
Answer:
He hires 8 workers
Explanation:
The total cost is $1600 for 5,000 chickens minus the fixed cost of $800, which equals $800. The total cost is total of fixed cost and variable cost as in absence of production the total variable cost is zero so from this we can conclude that total fixed cost is zero.
Then divide the total variable cost ($800) buy what Ralph pays his workers ($100), which comes to 8.
Answer:
a. 45%
Explanation:
The sum of total probabilities is always equal to 1. Since in the given question only three probabilities are given, so the sum of these three probabilities shall be 1 which is represented as follows by the equation:
probability of boom+probability of normal+probability of recession=1
In the given question:
probability of boom=30%
probability of recession=25%
30%+probability of normal+25%=1
Probability of normal=1-25%-30%=45%
So based on the above calculations, the answer shall be a. 45%
