We repeat steps three and four in the scientific method such as to form a hypothesis and conduct an experiment in order to arrive at the perfect answer to the question and provide a right direction to further scientific investigation and most importantly in order to verify the results. Since different science disciplines have different criteria for determining what good results are. “Practice make perfect” is apparently true for the experimentation in order to develop skills which is necessary to extend established methods and develop new experiments. Lastly, The experiment must also be reproducible so that it can be tested for errors.

Helga [31]

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.

poizon [28]

b. Prepare the journal entries to record the acquisition costs.

Date X, 2021, acquisition of copper mine

Dr Copper mine 2,104,430

Cr Cash 1,780,000

Cr Asset retirement liability 324,430

July 1, 2021, acquisition of mining equipment

Dr Equipment 150,000

Cr Cash 150,000

Explanation:

estimated restoration costs = ($330,000 x .25) + ($430,000 x .4) + ($630,000 x .35) = $475,000

now we must adjust the restoration cost and determine its present value = $475,000 x 0.68301 (present value factor, 10%, 4 periods) = $324,430

total cost of copper mine = purchase cost + preparation costs + restoration costs = $1,150,000 + $630,000 + $324,430 = $2,104,430

At the beginning of the period, the Cutting Department budgeted direct labor of $30,000 and supervisor salaries of $20,000 for 3

frutty [35]

Answer:

Total labor cost= $70,000

Explanation:

The supervisor salary is a fixed labor cost, it is unlikely that would change with production.

First, we need to calculate the unitary variable direct labor hour:

Unitary variable direct labor hour= 30,000 / 3,000

Unitary labor hour= $10

Now, the flexible budget for 5,000 hours:

Fixed cost= 20,000

Variable cost= 10*5,000= 50,000

Total labor cost= $70,000
