What is Don Quixote?

Don Quixote is sometimes acknowledged as the first modern novel and is regarded by literary historians as one of the most significant books of all time. As a result of Quixote's archetypal status, the word "quixotic," which originally denoted the idealistic pursuit of impractical ends, has become widely employed.

On a donkey, Don Quixote and Sancho headed off. Don Quixote mistook a field of windmills for giants in their first adventure and tried to combat them, but eventually came to the conclusion that a magician must have transformed the giants into windmills.

In which situation, do you think Nationalism is well presented? Cite some examples that happened in real life.


type 3-5 sentences.

(this kind of subject is English and History!)

Answers

When a country is supporting its own interests, such as defending its borders, maintaining its culture, and fostering economic and social progress, nationalism is often well-presented.

When a nation or its citizens are threatened with losing their sovereignty or face a common enemy, nationalism is frequently persuasively displayed. This may be seen in the French Revolution, when the people rebelled against their repressive government in order to pursue independence and a feeling of identity. Another instance is the American Revolution, which was waged by American colonists to free themselves from the British and found the United States of America.

Thirdly, during the early 20th century struggle for Indian independence from British control, Indian nationalists organized campaigns of peaceful civil disobedience and rallies to demand their freedom. All of these instances show how nationalism can be an effective motivator for a people to stand up for their rights and independence.

Sam and Frodo are hobbits on an adventure to save middle earth. To save middle earth, Sam and Frodo venture to a special volcano to destroy an evil power-ridden ring. It's Frodo's job to destroy the ring, and it's Sam's job to protect and help Frodo. According to some calculations a wise wizard estimated, the probability that Frodo destroys the ring is 73%, and the probability that Sam decides to help Frodo on this journey is 82%. If Sam helps Frodo, the probability that Frodo destroys the ring is 67%. For the following questions, please provide your answers rounded to 2 decimal places. What is the probability of Sam deciding not to help and Frodo destroying the ring? Given that Sam has decided to help Frodo, what is the probability Frodo does not destroy the ring?

Answers

a) The probability of Sam deciding not to help and Frodo destroying the ring is approximately 0.09. b) The probability Frodo does not destroy the ring, given that Sam has decided to help Frodo is approximately 0.33.

In order to solve the probability of Sam deciding not to help and Frodo destroying the ring, we need to use the multiplication rule of probability which states that the probability of two independent events A and B both occurring together is the product of their probabilities.

Therefore, the probability of Sam deciding not to help and Frodo destroying the ring is:P(Sam not helping) x P(Frodo destroying the ring) = (1 - 0.82) x 0.73 = 0.13 x 0.73 = 0.0949 ≈ 0.09 (rounded to 2 decimal places)Therefore, the probability of Sam deciding not to help and Frodo destroying the ring is approximately 0.09.

b) In order to solve the probability Frodo does not destroy the ring, given that Sam has decided to help Frodo, we need to use the conditional probability formula which states that the probability of an event A occurring, given that event B has occurred is:

P(A|B) = P(A and B) / P(B)where P(A and B) represents the probability of both A and B occurring, and P(B) represents the probability of event B occurring. Therefore, the probability Frodo does not destroy the ring, given that Sam has decided to help Frodo is:

P(Frodo does not destroy the ring | Sam helps) = P(Frodo does not destroy the ring and Sam helps) / P(Sam helps). The probability Frodo does not destroy the ring and Sam helps is: P(Frodo does not destroy the ring and Sam helps) = (1 - 0.67) x 0.82 = 0.33 x 0.82 = 0.2714 ≈ 0.27.

Therefore, P(Frodo does not destroy the ring | Sam helps) = 0.27 / 0.82 = 0.329 ≈ 0.33 (rounded to 2 decimal places)

Therefore, the probability Frodo does not destroy the ring, given that Sam has decided to help Frodo is approximately 0.33.

All staff members are reminded that you should not use the executive restroom………you have written authorization to do so.

Answers

Answer:

unless

Explanation:

In English language, a conjunction can be defined as an English word that is typically used for connecting two or more clauses, words, phrases or sentences. Some examples of conjunction are but, and, although, because, or, yet, unless, so, however, nor, etc.

Unless is synonymous with "except if" or "if not" and as such it's a conditional statement. Thus, it's used to express an action that will or will not happen if something else isn't going to happen or not true (false).

In this scenario, staff members are instructed not to use the executive restroom, if they've not obtained a written authorization.

Hence, the complete sentence would be written as follows;

"All staff members are reminded that you should not use the executive restroom unless you have written authorization to do so."

Answers

Answer and Explanation:

Immigration is the term that refers to the entry of individuals in a country that is not their home country and to settle there and reside permanently or temporarily.

Immigration is a controversial topic in the USA, due to the constant and growing number of immigrants. Many people believe that immigrants cause problems they take resources from local citizens, they do not respect local culture, among other losses. However, this is far from being true, since immigrants have, for the most part, a very positive impact on the country.

First of all we must emphasize that the USA was formed by immigrants. The first colonizers were European immigrants who suffered a lot in the new environment to which they submitted, but who were resilient and allowed themselves to grow in America. Nevertheless, we can confirm that one of the successes of the American colonies was the vast number of immigrants that boosted the trade and enriched the country in a cultural way. Currently, we can say that immigrants continue to enrich the country with their cultures and ethnicities, in addition to being people who pay their taxes and are active members of their communities.

Unfortunately, many people ignore these facts and end up making immigrants' lives more difficult than they should be, being prejudiced, xenophobic, pretending they don't understand them and even imposing stereotypes and incorrect concepts on them.
