How do institutions like religion and politics play a role in creating or maintaining beliefs and preconceived notions?

Answers

Religion and politics play an important role in the society. Institutions like religion and politics can either damage or improve the mindset and the way of living of an individual. They also create a huge influence on how people behave, live, and survive. 
For instance, religion focuses with particularly in the system of faith and its practices. Their teachings can affect an individual as it helps them realize where they stand in life.
On the other hand, politics affects us individually because it has something to do with how an individual survive on his daily living. Politics cover our rights as a human and how we will interact with the environment.
We can conclude that our actions, beliefs, and thoughts are just an outcome of how we accepted them.

Religion and politics both have the ability of creating and maintaining a set pattern of beliefs which are resistant to change or questioning, even in the face of evidence that contradicts their preconceived convictions. 


In a religious system, there are accepted holy books and religious authority figures that establish what is considered true, and to question any of those accepted truths may be branded as heresy. Religious history contains a number of examples of religious institutions resisting and opposing other forms of knowledge, such as that produced by scientific inquiry. Galileo, for instance, was pressured by the Inquisition of the Roman Catholic Church to stop publishing ideas about the solar system that contradicted the church's assertions that the earth stands at the center of all of God's creation. 

Politics can function in a similar way when political perspectives become entrenched and resistant to any self-analysis or change. In the current political climate in the United States, conservatives (mainly on the Republican side of the aisle) see social programs run by the government as bad ideas that they battle against, while liberals (mainly on the Democratic side of the aisle) believe the government has a duty to carry out social programs for the common welfare of all citizens. The two sides can become as entrenched in their political beliefs as religious adherents are in theirs, and thus they become unwilling to compromise or work with others that are on the opposite side of the political spectrum.

Do you agree that racial discrimination against African Americans might be related to economic stratification? Justify your position with specific examples.

Answers

In a sense, the discrimination against African Americans is related to economic stratification. In the 17th century colonial Virginia, the concept of race was adopted and used as a justification for social classification for groups of people. This was a result of a violent uprising known as Bacon's Rebellion in which lower class African and Europeans both who were denied land holdings in the Virginia frontier. The rebellion was so destructive that the Virginian governing body set in place strict segregation between Africans and Europeans in a way to prevent them from collectively joining forces again to create another violent uprising. Since then, those of African have gradually lost certain rights and liberties in comparison to their Caucasian counterparts, to the imminent point in which Africans were nearly all reduced to the role of slaves. Even after the abolition of slavery, those of African descent were continuously denied abilities to obtain better economic and financial assets by a southern states that were still upset of losing their right to own slaves. This is evident by sharecropping being used as a way to keep African Americans on estates to work off for their freedom, as well as terroristic tactics used by the Ku Klux Klan, as well as forms of institutional racism that barred African Americans from the same working establishments as White Americans. In various ways, economic stratification has been a tool for discriminating African Americans throughout American history.

Hi! This problem follows the binomial distribution where there are only two outcomes - either Sandra gets a ride to work or not. A binomial distribution is modeled by the following equation:

[tex]P(x)= _{n}C_{x} p^{x} q^{n-x} [/tex]

where p is the probability of success for x trials and q is the probability of failure (n is the total number of trials). In the case of the problem p would be the probability of getting a ride which is equal to 0.7 while q would be 0.3.

To find the probability that she successfully gets a ride 3 out of 5 times, we just substitute 3 as the value of x:

[tex]P(3)= _{5}C_{3} (0.7)^{3} (0.3)^{2} =0.3087[/tex]

Meanwhile, to find the probability that she gets AT LEAST 2 out of 5 rides, we just get the probability that she gets 1 ride or no ride at all then subtract the sum of these two probabilities from 1.

[tex]P(0)= _{5}C_{0} (0.7)^{0} (0.3)^{5} =0.00243[/tex]
[tex]P(1)= _{5}C_{1} (0.7)^{1} (0.3)^{4} =0.02835[/tex]
[tex]P(x \geq 2)=1-[P(0)+P(1)]=1-(0.00243+0.02835)=1-0.03078[/tex]
[tex]P(x \geq 2)=0.96922[/tex]

ANSWER: The probability that Sandra gets a ride 3 times in a 5-day work is 0.309, and the probability that she gets a ride at least 2 times in a 5-day work is 0.969.

This map shows the Colorado River from the Hoover Dam to Lake Powell. Select whether the water of the river has potential energy (P.E.) or kinetic energy (K.E.) at each location listed below.

Answers

Hoover Dam & Glen Canyon Dam: P.E. (potential energy) due to high elevation.

Colorado River: K.E. (kinetic energy) due to flowing water.

Lake Mead & Lake Powell: Mix of P.E. (stored water) and K.E. (flowing water).

Hoover Dam: P.E. - The water is at its highest elevation here, held back by the dam, giving it significant gravitational potential energy.

Glen Canyon Dam: P.E. - Similar to Hoover Dam, the water is behind the dam at a high elevation, possessing potential energy.

Lake Mead: P.E. - While lower than the dams, Lake Mead is still a large body of water at a considerable elevation, storing potential energy.

Colorado River: K.E. - As the river flows between the dams and towards Lake Powell, it gains kinetic energy due to the pull of gravity and the gradient of the riverbed.

Lake Powell: P.E. and K.E. - Lake Powell has a mix of potential and kinetic energy. While most of the water is stored at a certain elevation (P.E.), some water might be flowing into the lake or within it (K.E.).
