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.

IceJOKER [234]

Answer:

The correct answer is:

(1) $15,054

(2) $12,990

Explanation:

The required table is not given in the question. Please find below the attachment of the table.

Given:

Future value,

= $30,000

If discounting rate is 9%, the present value will be:

= $Future \ value\times PV \ factor(9 \ percent, 8 \ years)$

= $30000\times (\frac{1}{1.09} )^8$

= $30000\times 0.5018$

= $15,054$ ($)

If discounting rate is 11%, the present value will be:

= $Future \ value\times PV \ factor(11 \ percent, 8 \ years)$

= $30000\times (\frac{1}{1.11} )^6$

= $30000\times 0.433$

= $12,990$ ($)

S_A_V [24]

Answer:

a) maximize 12x+16y subject to x+y≤60; x+2y≤80; 2x-3y≥0; x-9y≤0.

b) 40 fish and 20 beef dinners

c) $800

Explanation:

Let x and y represent the numbers of fish and beef dinners to prepare, respectively. Then the relations these values must satisfy are ...

x + y ≤ 60 . . . . . a maximum of 60 dinners will be sold

0.25x + 0.50y ≤ 20 . . . . . kitchen hours cannot exceed 20

x/y ≥ 3/2 . . . . . . at least 3 fish dinners for each 2 beef dinners will be sold

y ≥ 0.10(x +y) . . . . at least 10% of dinners sold will be beef

While satisfying these relations, we want to maximize the profit function:

p = 12x +16y

a) The linear programming problem can be formulated as ...

Maximize 12x +16y, subject to ...

x + y ≤ 60
x + 2y ≤ 80
2x - 3y ≥ 0
x - 9y ≤ 0

b) The graph shows the constraint inequalities with the comparison symbol reversed. The effect of that is to shade the area that is NOT part of the solution set, leaving the feasible region white. The vertex of the (white) feasible region that makes the profit line farthest from the origin is the solution we're looking for. Once the profit line is plotted so we can compare its slope to the lines bounding the feasible region, it becomes clear which vertex is the one that maximizes profit.

The solution is (x, y) = (40, 20).

40 fish dinners
20 beef dinners

c) The maximum earnings are estimated to be ...

($12)(40) +($16)(20) = $800

Which of the following materials could be potentially infected with bloodborne pathogens, assuming they are not mixed with human

Katena32 [7]

Answer:

Semen or vaginal secretions

Explanation:

"Bloodborne pathogens" refer to microorganisms that can be found in the blood or body fluids of humans. There are many kinds of bloodborne diseases such as Hepatitis B and Hepatitis C as well as Human Immunodeficiency Virus (HIV). They can be transmitted to another person through having contact with the infected human blood or body fluids.

Assuming that the materials above are not mixed with human blood (meaning, they are not contaminated with blood), then the semen or vaginal secretions are the only materials where the bloodborne pathogens can be transmitted. Thus, it is important not to have sexual contact with the contaminated person such as people with HIV.

So, this explains the answer.
