Briefly explain ONE important connection between the economic systems of the North and the South in the same period.

Answers

Answer:

An important connection between the economies of the north and south of the United States in the run-up to the Civil War was that the south was the primary producer of the raw materials used by factories and manufacturing industries in the north of the country.

Thus, there was a kind of internal trade between both regions, where the south was the main producer of raw materials, such as cotton, which was used by the northern textile industry for the production of different fabrics that were later exported to the nations of Europe.

1. Define, as simply as you can, reinforcement and punishment.
2. Explain how one might accomplish reinforcement and punishment through the use of positive reinforcement, negative reinforcement, positive punishment, and negative punishment. Include examples where appropriate.

Answers

Answer:

1. Reinforcement is when you are rewarded for doing something right. Punishment is to teach you that you are not doing something right and you must learn from it.

Explanation:

:)

Answer:

1. Reinforcement and punishment are two separate things. Reinforcement is used to increase the tendency of a particular response, while on the other hand, punishment is used to decrease the tendency of a particular response.

2. To accomplish reinforcement, one may use positive reinforcement or negative reinforcement. Positive reinforcement is a type of reinforcement in which the addition of a rewarding or pleasant stimulus increases the tendency of a particular response. For example, when a student receives an A+ on a test, the student gets to go to the ice cream shop. Negative reinforcement is a type of reinforcement in which the removal of an unwanted or unpleasant stimulus increases the tendency of a particular behavior. For example, when a student receives an A+ on a test, they no don't have to wash the dishes that night.

To accomplish punishment, one may use positive punishment or negative punishment. Positive punishment is a type of punishment in which an unwanted or unpleasant stimulus decreases the tendency of a particular response/behavior. For example, a teen stays out past curfew and now has to do extra chores. Negative punishment is a type of punishment in which the removal of a rewarding or pleasant stimulus decreases the tendency of a particular response. An example of this would be a child getting in trouble and having her favorite toy taken away.

Wastewater from which source is technically considered graywater, but should be treated as blackwater?

toilet

shower

washing machine

kitchen sink

Answers

Answer:

the answer is D, kitchen sink

Explanation:

i just took the test.

Wastewater from kitchen sink is the technical source considered graywater, but should be treated as blackwater. Thus, option D is correct.

Answers

Answer:

Jefferson of the Democratic-Republican Party defeated incumbent President John Adams of the Federalist Party. The election was a political realignment that ushered in a generation of Democratic-Republican leadership.

Explanation:

Thomas Jefferson was the third President of the United States, from 1801 until 1809. He was also Vice-President of the United States from 1797 to 1801 and the main author of the Declaration of Independence.

Jefferson belonged to the Democratic-Republican Party, opposed to the Federalist Party (which supported the British policies in Europe, more conservative). Therefore, Jefferson had a republican ideological alignment that was concordant with that of the French Revolution, which was rightly opposed to the conservatism defended by the federalists.

Therefore, the events that took place in France during the late 1790s greatly influenced the political stance of Jefferson and his supporters facing the presidential elections of the year 1800.

Answers

Answer:

1.6%

Explanation:

The natural annual percent increase of its population is 1.6%.

Since the country has a crude birth rate of 24 per 1,000, this can be represented as a decimal which will be 0.024.

Since the crude death rate is 8 per 1,000, this will be represented as a decimal as: 0.008.

Therefore, the natural annual percent increase of its population will be:

= 0.024 - 0.008

= 0.016

Please and Thanks :)

Answers

The correct answer to this open question is the following.

Mass media and communications technology can be used to preserve indigenous languages in the Americas in different ways.

According to the graphics attached, we can see that in the Americas, 17% of the languages are lost and 16% are endangered.

This data is critical and concerns not only scholars or historians, but it has to worry all the citizens because part of our history can be erased if indigenous languages disappear.

Mass media can be used to help solve this issue because modern technology has no frontiers. If governments invest in proper technological infrastructure to take modern communications systems to the tribes or far away places where many tribes inhabit, this could be a direct way to rescue those endangered languages. This possibility shows that there are options available. The use of the internet is a great resource, proving that no matter the distance, every member of a society or indigenous tribe can be connected and could take classes on the internet, or listening to news broadcasting systems in their former language, as well as reading publications in their languages.

The following table shows summary statistics, in thousands, for the number of electrical workers and the number of concrete workers in the construction industry each month for the past 5 years.

Based on the 1.5×IQR rule for outliers, which of the following statements is a correct comparison of the two distributions?

Answers

Answer:

The electrical  workers data is correct comparison of the two distributions based on the 1.5× IQR rule for outliers.

Explanation:

Outlier> 1.5 *IQR + 3rd Quartile

Outlier < 1st Quartile-1.5 *IQR

where

Interquartile Range (IQR) = 3rd Quartile- 1st Quartile

                   IQR (electrical) = 320-278= 42

                   IQR (concrete) = 308- 262= 46

Outlier for Electrical Co workers=

Outlier> 1.5 *IQR + 3rd Quartile= 1.5*42 + 320= 63+320= 383

Outlier < 1st Quartile-1.5 *IQR=278-1.5*42=278-63= 215

The minimum for electrical workers is 239 and maximum is 330.

215 < 239

383> 330

By comparing the values we find there are no outliers in the electrical workers data.

Outlier for Concrete Co workers=

Outlier> 1.5 *IQR + 3rd Quartile= 1.5*46 + 308= 69+308= 377

Outlier < 1st Quartile-1.5 *IQR=262-1.5*46=262-69= 193

The minimum for concrete workers is 186 and maximum is 335.

377>335

193>186 The minimum is the outlier.

By comparing the values we find there is one outlier in the concrete workers data.

Electromagnetic waves can carry energy through matter.
Electromagnetic waves can travel through empty space.
Electromagnetic waves can move through gases faster than other types of energy transfer.
Electromagnetic waves can move more energy than other types of energy transfer.

Answers

Answer:

Electromagnetic waves can travel through empty space

Explanation:

Electromagnetic waves can travel through empty space.

What are Electromagnetic waves?

Invisible energy forms called electromagnetic waves are able to move throughout the cosmos. Nonetheless, some of the effects of this energy are visible. The electromagnetic spectrum includes the light that our eyes can see.

The colors we see in a rainbow, from reds and oranges to blues and purples, are all part of the visible portion of the electromagnetic spectrum. In reality, each of these hues represents a distinct light wavelength.

We are unable to observe the waves that create the sound we hear. In order for sound waves to go from one location to another, they need a medium to pass through. Because air is composed of molecules, sound can move across it.

Therefore, Electromagnetic waves can travel through empty space.

Write an overview of the impact of cognition on learning, and discuss how it has changed behaviorism. In your response, discuss the concepts of cognitive map, latent learning, insight, intrinsic motivation, and extrinsic motivation, and give a personal example of each concept.

this is for ap psych so just write a free response basically

Answers

Answer:

Cognition helps us during our emotions, perceptions, and senses, to gain awareness. Learning requires the acquisition of skills through experience, research, and instruction. It is not possible to learn details if the pupil is overwhelmed. And we are seeing that even as time goes on, we grow and that this enables everybody a stronger person of ourselves. Perhaps it makes change easy for any of us. Throughout all sorts of backgrounds, cognition has almost always motivated us, but that always encourages everyone to be a stronger version every once throughout a while of development.

Over experience, we had to make sure these people fall throughout the correct position as well as the data flow becomes crisp and seamless. I learned the most from my mum, and by studying and knowing situations in that same elite environment, this has already been instilled. This is a perfect way to evolve in life plus benefit from lessons from everyday life as well.

Explanation:

Answer:

Cognitive skills help students to build upon previous knowledge and ideas- with a deeper understanding of topics and stronger learning skills, students have the ability to approach schoolwork with enthusiasm and a little confidence. Cognition itself has effected behaviorism by altering the original conceptions of the human mind and creating a significant influence on classroom instruction and psychopathology. This has lead to the rise in cognitive science, and the eventual demise of the dominance of behaviorism. A cognitive map is a mental representation of the layout of someone's environment, for example, if a rat/multiple rats have explored a maze enough, they may act as though they have a cognitive map of it. An example of a cognitive map from my own life would be describing landmarks, roads, amount of turns, etc. to my friend who asked directions to come over to my house. Latent learning is a type of learning that does not happen at the exact time of learning, but instead appears later when suitable motivation and circumstances come into play. A personal example of latent learning would be learning how to do a math problem in class, but not immediately being able to do it without the incentive of getting a good grade on an upcoming test. Insight is when an answer to a problem becomes apparent quickly and abruptly- an example from my personal life would be keeping my dogs in a fenced-off area to keep them from running away. Intrinsic motivation is the act of completing an action without any obvious external rewards, like when I was younger, I used to read books so much and so often, just because I loved reading and wanted to do it. Extrinsic motivation, on the other hand, is doing/completing an activity for the purpose of a reward. For example, as a young child in the classroom, the promise of a "pizza-party" or "treat-day" drove me (and my classmates, of course) to do well and win the treats.
