Answer:
The data-mining technique that creates a report or visual representation is summarization.
Explanation:
The business world has changed drastically over the years in terms of marketing and service delivery because of growth in technology. The use of machines and internet has caused a greater need for access and analysis of information in such a way that can make a business thrive in the market. This means that most businesses have to look into better data-mining techniques that can assist them in the competitive business environment.
The different data mining techniques include; association-rule learning, classification, summarization and regression. They are explained further as follows:
1. Association-rule learning: this is a machine learning technique that discovers a relationship between large databases using the concept of strong rules.
2. Classification: this technique finds similarities in features of two or more data sets and groups them into the same category.
3. Regression: this is a predictive technique that is used to identify and analyse the likelihood of a specific variable.
4. Summarization: this technique takes the results from the data and puts it in a way that it is short and understandable by most people. It usually involves the use of tables and other data summarization software like Excel sheets to represent the data in a way that conclusions can easily be drawn. Data summarization is important especially in the digital world where large amounts of data are available for analysis and transfer. This technique helps in breaking down huge data into short comprehensible reports that can easily be used for quick decision making.
Complete Question:
The market system:
A. produces considerable inefficiency in the use of scarce resources.
B. effectively harnesses the incentives of workers and entrepreneurs.
C. is not consistent with freedom of choice in the long run.
D. has slowly lost ground to emerging command systems.
Answer:
B. effectively harnesses the incentives of workers and entrepreneurs.
Explanation:
An economic system can be defined as a series of governmental or societal arrangements and a coordinating mechanism used for the allocation of available resources, economic inputs, goods and services across a particular country. The economic system differs according to the method used to coordinate economic activities and who the factors of production belongs to.
Generally, there are basically two (2) main types of economic systems and these are;
1. Command systems.
2. Market systems.
The market system effectively harnesses the incentives of workers and entrepreneurs because workers are able to engage in division of labor and are well compensated for their efficiency in service while the entrepreneur are usually rewarded with an increase in sales and profits.
The market system allows participants to have property rights such as trademarks, patents and copyright. Also, market systems are regulated by the competition among individuals (traders or entrepreneurs) and this gives direction to the market as they pursue self interests and are independent.
Answer: $18,224 unfavourable
Explanation:
The materials quantity variance for the month will be calculated thus:
= Standard Cost per unit × ( Actual materials Used - Actual output)
= 13.4 × [( 4,300 - 700) × 4.2]
= $18,224 unfavourable
Therefore, the materials quantity variance for the month is $18,224 unfavourable
Answer:
PLAN A:
(120 * 0.39) + (40 * 0.19) + 20 = $74.40
PLAN B:
(120 * 0.49) + (40 * 0.14) + 20 = $84.40
PLAN C:
$20 + $75 = $95 ;
PLAN A is optimal from 0 to 192 minutes
PLAN C is optimal from 192 minutes onward ;
Explanation:
PLAN A :
Service charge = $20
Daytime = $0.39 per minute
Evening = $0.19 per minute
PLAN B :
Service charge = $20
Daytime = $0.49 per minute
Evening = $0.14 per minute
PLAN C :
Service charge = $20
225 minutes = $75
Minutes beyond 225 = $0.36 per minute
A.)
Determine the total charge under each plan for this case: 120 minutes of day calls and 40 minutes of evening calls in a month.
PLAN A:
(120 * 0.39) + (40 * 0.19) + 20 = $74.40
PLAN B:
(120 * 0.49) + (40 * 0.14) + 20 = $84.40
PLAN C:
$20 + $75 = $95
b. If the agent will use the service for daytime calls, over what range of call minutes will each plan be optimal?
PLAN A:
20 + 0.39D = 95
0.39D = 95 - 20
D = 75 / 0.39
D = 192.31
