Based on Carroll’s global corporate social responsibility pyramid, Amy’s is fulfilling which of its responsibilities?
Multiple Choice
legal and ethical
ethical and philanthropic
economic, legal, ethical, philanthropic
economic
economic and ethical

Answers

Hello. You forgot to put the text that shows what Amy is doing. This makes it impossible to answer your question, but I can help you by showing you what each answer option represents.

Answer:

If Amy is fulfilling her legal and ethical responsibilities she is in a situation where she is complying with all laws and doing what is right and fair, even if it is disadvantageous for her.

If Amy is fulfilling her ethical and philosophical needs she is in a situation where, in addition to performing fair and correct actions, she is helping her community, being a good citizen and promoting improvements to other citizens.

If Amy is fulfilling her economic, legal, ethical and philanthropic obligations she is in a situation where, in addition to promoting good for the community, through fair and correct actions, she is complying with all laws and is still receiving economic profit for that.

If Amy is fulfilling her economic responsibilities, she is in a situation where her activities and skills are generating economic profit.

If Amy is fulfilling her economic and ethical responsibilities, she is in a situation where her activities are all correct and fair and generate economic profit.

Explanation:

Carroll's global corporate social responsibility pyramid is a pyramid model that shows the social responsibilities a company must have. This scale has 4 parts, the first part being the base of the pyramid, the economic responsibilities, which show that a company must, first, be responsible for the economic profit. The second part refers to legal liability, which states that a company must always act within the law, without exception. The third part refers to ethical responsibilities, which states that a company's activities must always be fair, regardless of the results. In the last part that represents the top of the pyramid are the philanthropic responsibilities that affirm that the company must design its activities to promote social good to the community as a whole.

Answer:

economic, legal, ethical, and philanthropic

Explanation:

Amy’s is fulfilling everything in the pyramid.

what is chance music?​

Answers

Answer:

CHANCE MUSIC  The musical styles that evolved in the modern era were varied. These devices are used for creating and recording music to add to or to replace acoustical sounds

Explanation:

Answer: chance music is just another word for Aleatoric music

Among notable aleatory works are Music of Changes (1951) for piano and Concert for Piano and Orchestra (1958), by the American composer John Cage, and Klavierstück XI (1956; Keyboard Piece XI), by Karlheinz Stockhausen of Germany.

Aleatoric/Chance music is music in which either composition or method of performance is determined by elements of chance or unpredictability. Music composed by the random selection of pitches and rhythms. Frequently found in some professional opera choruses.

Aleatoric music (also aleatory music or chance music; from the Latin word alea, meaning "dice") is music in which some element of the composition is left to chance, and/or some primary element of a composed work's realization is left to the determination of its performer(s).

Why are maps important in today’s society? Explain at least two reasons.

Answers

Answer:

1. Maps Simplify Complicated Information

Maps take complex data sets and display them in a pleasing graphic you can use to answer questions about your world.

Imagine that you’re back in elementary school and you ask your teacher to show you how big the United States is compared to other countries. She nods her head, walks over to the spring roller, and pulls down a huge spreadsheet that lists each country and their areas. Huh?!?!

Maps are a visual representation of complicated data. Some may think maps are unnecessary and complicated tools, but in reality, maps simplify your life.

2. Maps Can Save Your Life

According to The National Park Service (NPS), there are more than 300 million people visiting national parks, forests, and wilderness areas every year. Spoiler alert, cell signals don’t extend to all these areas and maps may be the only reference you’ll have in an emergency.

If there’s flooding near you, you’ll need to know how to get to the closest high elevation. If an injury happens, you’ll need to get to the nearest high traffic area for help. If a bear cuts off your path, you’ll need to find an alternate….fast.

So don’t get caught out there holding your phone to the sky begging for a signal. A paper map may actually save your life.

the individual tastes and preferences of buyers.
O the cost of raw materials and natural resources.
O the availability of workers in automobile factories.
O a company's ability to respond to buyers' interest.

Answers

Answer:

A. the individual tastes and preferences of buyers

Explanation:

A factor that most directly affects the demand for automobiles is the individual tastes and preferences of buyers. Hence, option A is correct.

What are tastes and preferences of buyers?

Economists refer to everything we desire in life as "tastes and preferences." These preferences may be minor—for example, the toppings on our pizza—or significant—for example, the type of work we enjoy doing or how we like to spend our free time.

The overall outcome of a customer's choice, taste, and utility is what is known as their consumer behavior. Consumers' perceptions of the satisfaction they anticipate getting from a certain commodity or service that suits their taste vary.

Taste perception can be impacted by consumer taste experiences that are influenced by heredity, location, cultural variations, frequently eaten flavors, meals, and more. You might therefore be more sensitive to some tastes and flavors than others as a result.

Thus, option A is correct.

Replication increases scientific confidence in a theory if the:__________.a. reviewing the literature of existing theories b. forming a testable hypothesis c. developing a theory d. designing a study

Answers

Answer:

a. reviewing the literature of existing theories produces similar results.

Explanation:

Replication refers to the repetition of a research study, or literature review usually with various circumstances and topics, in order to decide if the basic results of the initial study can be generalized to other respondents and situations. When replicating experiments, and obtaining the same results as the actual study , the results are given greater validity. If an investigator is able to reproduce the findings of a study it indicates that it is more likely to generalize the results to the wider population.
