Explanation:
Given
[tex]\left[\begin{array}{cc}a&b\\c&d\end{array}\right][/tex]
Required
Determine the determinant
Represent the determinant with D
Since the above matrices is 2 by 2.
All we have to do is to multiply the alternate elements of the columns
i.e. (a * d) and (b * c)
Then subtract:
[tex]D = (a * d) - (b * c)[/tex]
Simplify
[tex]D = (ad) - (bc)[/tex]
[tex]D = ab - cd[/tex]

Question: Given P(X) = 0.5, P(Y) = 0.4, and P(Y|X) = 0.3, what are P(X and Y) and P(X or Y)? (3 points)
A. P(X and Y) = 0.9, P(X or Y) = 0.75
B. P(X and Y) = 0.9, P(X or Y) = 0.1
C. P(X and Y) = 0.75, P(X or Y) = 0.15
D. P(X and Y) = 0.15, P(X or Y) = 0.1
E. P(X and Y) = 0.15, P(X or Y) = 0.75
Answer:
[tex]P(x\ and\ y) = 0.15[/tex]
[tex]P(x\ or\ y) = 0.75[/tex]
Explanation:
Given
[tex]P(x) = 0.5[/tex]
[tex]P(y) = 0.4[/tex]
[tex]P(y|x) = 0.3[/tex]
Solving (a): [tex]P(x\ and\ y)[/tex]
In probability, this is calculated as:
[tex]P(x\ and\ y) = P(x) * P(y|x)[/tex]
This gives:
[tex]P(x\ and\ y) = 0.5 * 0.3[/tex]
[tex]P(x\ and\ y) = 0.15[/tex]
Solving (b): [tex]P(x\ or\ y)[/tex]
In probability, this is calculated as:
[tex]P(x\ or\ y) = P(x) + P(y) - P(x\ and\ y)[/tex]
This gives:
[tex]P(x\ or\ y) = 0.5 + 0.4 - 0.15[/tex]
[tex]P(x\ or\ y) = 0.75[/tex]

Explanation:
Maddie is studying for her final exams. Explain how the curve of forgetting, effortful processing, and distributed practice may impact her learning and performance on the exam.
Answer:
The curve of forgetting describes how we forget what we have learned as time passes. To decrease forgetfulness over the new information acquired, Maddie should use two strategies: distributed practice and effortful processing.
By using distributed practice, the curve of forgetting decreases, and she will effectively retain the information. This practice consists of reviewing the new information soon after Maddie learned to prevent a high lowering in the forgetting curve. Then, she should study the lesson again, and continue doing this but with long periods in between reviewings. The result is a reduction in the forgetting curve, and Maddie has encoded the information in her memory.
The second strategy is effortful processing. This technique consists of paying attention and make a conscious effort to retain the information and not forget it. By doing this, Maddie will decrease the forgetting rate.
If Maddie combines the knowledge about the forgetting curve with distributed practice and effortful processing, she will succeed in her final exams since she managed to encode the necessary information.
Explanation:
Psychologist Hermann Ebbinghaus created the forgetting curve after his investigation about memory and how we retain information. He found out that we remember what we have learned less as time goes by. But also that there are methods to prevent the loss of memory over time. Distributed practice, effortful learning, finding a purpose to retain the information and making the information clear, sleeping well, and being relaxed helps to encode it in our memory.
Based on the information given, it should be noted that the curve of forgetting describes how individual forgets what we have learned as time passes.
In order to reduce forgetfulness over the new information that one has acquired, it's important for Maddie to use distributed practice and effortful processing.
Distributed practice will help her effectively retain the information. Also, effortful processing consists of paying attention and making a conscious effort to retain the information and not forget it.

Punishment and reinforcement are often confused with each other, especially when the positive and negative are involved. Respond to parts 1 and 2 below. Define, as simply as you can, reinforcement and punishment. 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.
Answer:
1. Reinforcement is when a reward is given or a bad stimulus is removed to make a specific behavior increase in frequency. A punishment is the addition of an unwanted event or the removal of a wanted stimulus in order to decrease a specific behavior.
2. Positive reinforcement is when a reward is added to increase a behavior, like giving a reward for returning a lost wallet. Negative reinforcement is when you remove an unwanted stimulus, like not nagging a child when they do their chores. Positive punishment is when you add an unwanted stimulus to stop the behavior, like spanking a child when they're bad. A negative punishment is when you remove a wanted stimulus, like taking away video games when the student hasn't done their homework..

My husband is a kid at heart so he absolutely loved spending an afternoon reminiscing with some of his favorite childhood games. There is no need to raid the piggy bank for quarters. A wristband ($13 per adult, $7 per child) allows you access to play unlimited games all day. You are welcome to come and go as you please so you can take breaks for lunch or to shop for soaps and sponges at the Sponge Docks.
My only complaint is that my husband insisted that we play all of the games as two players and he managed to crush my high scores on every game! Will definitely be returning to Replay Amusement Museum for a rematch soon!
Note to the parents: This is not an arcade that you can drop your children off at. All minors must be accompanied by an adult and anyone entering the building must pay for a wristband.

Explanation:
What is dose response and explain how it is measured and why it varies between individuals?
Dose-response relationship, effect on an organism or, more specifically, on the risk of a defined outcome produced by a given amount of an agent or a level of exposure. A dose-response relationship is one in which increasing levels of exposure are associated with either an increasing or a decreasing risk of the outcome. Demonstration of a dose-response relationship is considered strong evidence for a causal relationship between the exposure and the outcome. The chance of a causal relationship cannot be disregarded, however, even when a dose-response relationship is absent.

2. Explain what Gladwell means when he claims “you have to be intelligent enough” or “intelligence has a threshold” in relation to becoming an outlier.
Answer:
It means that an individual who believes to be an outlier has to be smart enough to have a perception of his position in the groups in which he lives, however this perception must be punctual and limited so as not to create problems and discomfort for himself.
Explanation:
This is because an outlier is an individual who is part of a group of other individuals, but who is different and does not fully fit the standard determined and observed by the members of that group. In this case, it is important that the outlier is smart enough to understand that it is different and that this group limits or harms him, so he can look for other groups that offer more advantages. However, this intelligence must be limited, as it is very difficult to establish a group that is fully adapted to the outlier and if that individual finds differences in any group that participates, he will be harmed, because he will live in complete isolation.

Briefly explain how ONE historical event or development in the period 1830 to 1860 that is not explicitly mentioned in the excerpts could be used to support Hahn’s interpretation.
The correct answer to this open question is the following.
You did not provide any excerpt, text, reference, or context to answer this question. That makes it difficult to exactly what you are referring to.
However, trying to help you and doing some research we can say the following.
One historical event or development in the period 1830 to 1860 that is not explicitly mentioned that could be used to support Hahn’s interpretation is how the United States became the engine of the ecom¿nomy of the planet because of its industrial capacity. How the Gross Domestic Product grew and the many opportunities the US offered to immigrants to work in major industries such as the Standard Oil Company of John F. Rockefeller, or the Steel company of Andrew Carnegie.
Innovations and the use of technology helped industries to earn more profits and invest that money in the creation of jobs and the spread of their operations nationwide.
A development in the period 1830 to 1860 that was not stated is the economic growth in the United States.
It should be noted that during the 80s, there was industrialization in the United States as several investors invested in the economy.
As a result of this, there was an increase in the gross domestic product of the country. This brought about economic growth and development in the country.
