Li designed a survey to determine how comfortable students at her middle school are with fractions. There are 600 students in her middle school. The students are equally distributed among grade levels. She selected a sample of 28 students in her first-period class. Which best explains Li’s sample?

[ad_1]

The correct answer to this is:

Nonrandom and biased

 

The method of Li’s sampling has a
tendency that some elements or portion in the population has no chance of
selection. Further, it was not stated which portion of the population she
obtained the sample thus we cannot accurately determine the probability of
selection. This kind of sampling results in a bias. A biased sampling is a type
of nonrandom sampling.

What is the theme of Ode to a Grecian Urn? A. Beauty is eternal. B. Beauty is a universal language among friend and foe. C. both of these D. none of these

[ad_1]

Answer:

Option B. The theme of “Ode to a Grecian Urn” is that beauty is eternal.

Explanation:

“Ode to a Grecian urn” is a poem written by the English poet John Keats in May 1818 and anonymously published on 1820 in an Art magazine. The central theme of the poem examines the eternity that beauty and truth holds and relates them to how our own lives are transcendent. For the speaker,it is through beauty that humankind connects to the truth, and how complex it is for us to comprehend that both concepts, truth and beauty, are indeed eternal while our existence is not. The speaker is not only meditating on beauty and its connection to art but at the same time is trying to understand the complex emotions that death awakens in him, and how inevitable it is.

Why did trade among the colonists flourish?

[ad_1]

Colonies were founded with specific trade agreements in places.

Its called specialization. Its because it was easier and cheaper for each colony to produce what suited them better. So one place that didn’t have a lot of lumber could trade something with the lumber colony. It makes things way more efficient. Instead of wasting energy on producing a lot of things, you specialize, get good at something and trade for everything else.

PLEASE HELP!!!!!! The Jonas school district gives awards to its schools based on overall student attendance. The data for attendance are shown in the table, where Low represents the fewest days attended and High represents the most days attended for a single student. School Low High Range Mean Median IRQ σ High School M 128 180 62 141 160 55.5 41.5 High School N 131 180 49 159 154 48.5 36.5 High School P 140 180 40 153 165 32.5 31.5 Part A: If the school district wants to award the school that has the most consistent attendance among its students, which high school should it choose and why? Justify your answer mathematically. Part B: If the school district wants to award the school with the highest average attendance, which school should it choose and why? Justify your answer mathematically.

[ad_1]

Answer:

High School P has the most consistent attendance among its students.

School N should be awarded for the highest average attendance.

Step-by-step explanation:

Consider the provided information.

Part A: If the school district wants to award the school that has the most consistent attendance among its students, which high school should it choose and why? Justify your answer mathematically.

Standard deviation (σ) is a measure of how a data set is spread out.

If the standard deviation is low, this implies that the information tends to be near to the set mean, whereas a high standard deviation implies that the information points are spread across a wider spectrum of values.

Therefore, for more consistency we need to look for the low standard deviation.

From the provided table we can see that the school P has low standard deviation (σ) i.e 31.5

Hence, High School P has the most consistent attendance among its students.

Part B: If the school district wants to award the school with the highest average attendance, which school should it choose and why? Justify your answer mathematically.

The formula for mean is:

Mean=frac{x_1+x_2+...+x_n}{n}

Mean is the same as average.

The sum of mean or average will be larger if each students contributes more attendance.

For highest average attendance the school with higher mean should be awarded.

Hence, School N should be awarded for the highest average attendance.

Read the excerpt from Early Victorian Tea Set. Among the upper classes, tea had been popular since before 1700. It received celebrity endorsement from Charles II’s queen, Catherine of Braganza, and from Queen Anne. It came from China, it was expensive, refreshingly bitter and drunk in tiny cups without milk or sugar. People kept their tea in locked tea caddies, as if it were a drug; for those who could afford it, it often was. In the 1750s Samuel Johnson confessed himself a happy addict: A hardened and shameless tea drinker, who has for twenty years diluted his meals with only the infusion of this fascinating plant, whose kettle scarcely has time to cool, who with Tea amuses the evening, with Tea solaces the midnights, and with Tea welcomes the morning.

Which sentence gives evidence to support the main idea that ads for junk food are bad for children? The advertising industry spends billions of dollars every year on ads targeted toward children. Many of these ads promote junk foods, which lead to weight gain among children. A World Health Organization report shows that junk food ads harm children’s health. The only way to prevent kids from eating large amounts of unhealthy food is to strengthen laws that control advertisers. Some countries like Sweden have already taken steps to protect children from such ads. But controlling these ads on the Internet and other places may prove to be a big challenge. So, the final responsibility to protect children falls with their parents. Children need to be educated and guided to make healthy food choices. i need help asap

Industrialization led to rising imperialism because 
1) show of power: As one makes new technology, they would either want to test it out or show the other nations that what they produce is ground-breaking and the best. Usually if it is military technology, you would want to test it out, and with the use of “show of force”, can have people groups submit to your country.
2) Better technology: As technology advances, it usually makes something easier. In the case of imperialism, better military advances meant that they could (once again) have other people submit to you
3) Better transportation: This meant that you could take multiple countries at once, and can prove that you’re country is great by having supplies shipped over long distances to keep your troops up. If in need of more troops, you could send more.

Why was America’s victory at Yorktown among the most significant battles of the American Revolution?

[ad_1]

The Reformation actually started after Columbus’s landing in North America. 

Treaty of Tordesillas in 1494 was forced on Spain and Portugal by the Pope. The Pope basically said that all lands in the New World belonged to Spain and all new non-Christian lands in the Eastern Hemisphere belong to Portugal. No other Catholic countries can do anything in those areas without the approval of the owner. 

The pope basically drew two lines on the globe setting the border. The western line started at the north pole cut half way through Greenland and ended at the south pole. The new world was everything to the west. Problem is that it ran through a chunk of Brazil which is why Brazil is an ex-Portuguese colony. 

The Eastern line starts at the North Pole runs through siberia, through the pacific just west of Japan, and cuts Australia in half. Of course, Australia hadn’t been discovered yet. Everything to the the east of this line is the new world. 

Obviously, this treaty didn’t hold up well, but the reformation gave the protestant countries an excuse to explore the new world since they didn’t have to take orders from the Pope. Even so, France, a catholic country, ignored it too. 

Really, the only country that was effected by the reformation in the exploration of the Americas was England. All the other countries, changed their religion once and then went to war with the nearest catholic country. Sweden became Lutheran and stayed that way. The Dutch Republic became Calvinists and stayed that way. 

England kept switching. First it was Catholic. Then, Henry VIII made it protestant. Then, Henry’s daughter Mary I made it catholic again. Henry’s other daughter Elizabeth I (with the two hit movies) made it Protestant again. 

Years latter, Oliver Cromwell over through the monarchy, executed the King Charles I, and established a Protestant fundamentalist religious military dictatorship. He outlawed drinking,smoking, gambling, theater, dirty books, sports, prostitution, and anything generally fun. He would have made Saudi Arabia proud. Basically, all you could do is work, pray, and die. Sex was allowed for creating children, but you couldn’t enjoy it. 

When Cromwell died, the people of England said enough was enough and brought back the King. Charles II kicked out the fundamentalists and brought back drinking, smoking, gambling, dirty books, sports, prostitution, and having fun during sex. Incidentally, those were also all his hobbies. 

This brings us to the famous Pilgrims. They were part of Cromwell’s crowd. They kept agitating a return to the no-fun policy. They annoyed everybody. They weren’t persecuted for practicing their religion, they were persecuted because they kept trying to force their religion on everyone else. Sort of like Southern Baptists. 

Charles II was the most easy going monarch in British history. Do realize how annoying you have to be to get him to throw you out. 

Charles’s brother James II was obsessed with turning Great Britain catholic again. After four years of trying, they kicked him and his followers out.

[ad_1]

Answer:

The answer is C. In order to carefully control conditions and confirm or disconfirm a hypothesis about the causes of behavior, one must perform an experiment.

Explanation:

Experimental research allows the researcher to control all the variables in order to create the conditions that can confirm or disconfirm a hypothesis. This method aimes to establish a relation of causality between two variables, which means that one variable is generated and determined by the other; this is posible because all of the other variables that can influence it have been controlled.

When a researcher conducts a survey or engages in naturalistic observation, he can’t control the variables, therefore, he can only establish a correlation between two variables, but not of causality.

Well I live in Florida so; I can explain tourism has always had a large role in our history. During our development, tourism gave us the much needed boost in economy that we needed to get on our feet. People coming from all over to enjoy the oranges and warm sun and beaches was a large source of income for people all over. More people to boy products = a larger income. The ‘boom and bust’ is what im guessing was the time right before the stock market crashed. Americans were richer then ever, they took more vacations, they generally thought of themselves having a brighter economic future, which caused more spending, more vacations, more extravagance. This made Florida truly flourish for a time, becoming a hotspot for wealthy vacation homes. The Great Depression almost killed us.. many buisness owners had come to depend on tourism to make a living wage, but since the great depression loomed over everyone, no one took vacations. No one had extra money to spend. Many of those wealthy vacation homes went into foreclosure. The Floridian Economy tanked during this time, so bad we even feel ripple effects of it today, even though we have built up so much more.

USING SEMICOLONS AND COLONS CORRECTLY Correct the punctuation in the following sentences by re-writing the sentence, adding semicolons and colons where they are needed and by changing other punctuation and capitalization as needed. Example 1. The following items were among those rationed in the United States during World War II coffee, cars, sugar, and tires. Corrected version: The following items were among those rationed in the United States during World War II: coffee, cars, sugar, and tires. In Washington, D.C., we visited three museums in a single day the National Portrait Gallery, the Freer Gallery of Art, and the National Museum of Natural History.

[ad_1]

Answer:

In Washington D.C., we visited three museums in a single day : the National Portrait Gallery, the Freer Gallery of Art, and the National Museum of Natural History.

Explanation:

The correct rewriting of the sentence will be –

In Washington D.C., we visited three museums in a single day : the National Portrait Gallery, the Freer Gallery of Art, and the National Museum of Natural History.

The use of the comma right after Washington is wrong as it is the name of a single particular place so it should instead be written as Washington D. C.

Also, a semicolon has to be inserted in between day and the. Since the sentence lists a number of places, the use of a colon is necessary to show the list of the places visited.

So, the changes in the sentence are-

(a) remove the comma (,) in between Washington and D.

(b) put a colon (:) right next to the word “day”.

Section 4 also establishes that both Congress and State legislatures can regulate the “times, places, and manners of holding elections for Senators and Representatives”. The federal election laws that the Constitution gives in order to regulate the election of members of the Congress cover all the aspects of the voting process, such as voter registration, prevention of fraud and methods to organize the results. The Constitution also gives the guarantees and rights for voting and for participating in a Congress election regarding citizenship, residency and age requirements.
