Answers

Answer 1

In order for researcher to obtain random sample, they need to specifically ensure that each person in population has an equal chance of being selected for sample.

What is a population?

The whole population of a place, such as a city or town, region, country, continent, or the entire world, is frequently referred to by the phrase "population." Governments routinely count the number of residents in their area via a census, a process for gathering, evaluating, summarizing, and releasing demographic figures. A population is a group of organisms where any two individuals can reproduce, according to certain terminology used in the science of genetics. This shows that they may frequently exchange gametes to produce offspring that are usually fertile; as a result, this breeding group is also known as a gamodeme. In this situation, allele frequencies can be converted into genotype frequencies by expanding an appropriate quadratic equation, as shown by Sir Ronald Fisher in the creation of quantitative genetics.

i need help asap 100 points + brainlyest so u better hurry u got 4 minSelect the correct answer. Read this excerpt from Behind the Scenes, the autobiography of African American writer Elizabeth Keckley. Keckley was once a slave in the South and later worked as a dressmaker at the White House. Which sentence best summarizes the excerpt? I went to work in earnest to purchase my freedom, but the years passed, and I was still a slave. Mr. Garland's family claimed so much of my attention—in fact, I supported them—that I was not able to accumulate anything. In the meantime, Mr. Garland died, and Mr. Burwell, a Mississippi planter, came to St. Louis to settle up the estate. He was a kind-hearted man, and said I should be free, and would afford me every facility to raise the necessary amount to pay the price of my liberty. Several schemes were urged upon me by my friends. At last I formed a resolution to go to New York, state my case, and appeal to the benevolence of the people. The plan seemed feasible, and I made preparations to carry it out. When I was almost ready to turn my face northward, Mrs. Garland told me that she would require the names of six gentlemen who would vouch for my return, and become responsible for the amount at which I was valued. I had many friends in St. Louis, and as I believed that they had confidence in me, I felt that I could readily obtain the names desired. I started out, stated my case, and obtained five signatures to the paper, and my heart throbbed with pleasure, for I did not believe that the sixth would refuse me. A. The writer is an African American slave in Mississippi. B. The writer does not have any money to buy her freedom. C. The writer is trying to free herself from slavery. D. The writer has many friends who could vouch for her.

Answers

Answer:Elizabeth Hobbs Keckley (ca. 1818-1907) was born enslaved in Dinwiddie County, Virginia, to Agnes Hobbs and George Pleasant. Keckley experienced harsh treatment under slavery, including beatings as well as the sexual assault of a white man, by whom she had a son named George. She was eventually given to her owner's daughter, Ann Garland, with whom she moved to St. Louis. There she became a dressmaker and supported Garland's entire household for over two years. She married James Keckley around 1852, discovering only afterward that he was not a free man. Prior to her marriage, Keckley had negotiated with the Garlands to purchase her freedom and that of her son, but she could not raise the required $1,200, because of the strain of supporting her "dissipated" husband and the Garland household (p. 50). Sympathetic customers loaned Keckley the money to purchase her freedom and that of her son in 1855. In 1860, she left her husband and moved to Washington, D.C., where she set up a dressmaking shop. Keckley's clients were the wives of influential politicians, and she eventually became the dresser and close confidante of Mary Todd Lincoln. After President Lincoln's assassination, Keckley made several attempts to raise money for the former first lady. Keckley published Behind the Scenes, or, Thirty Years a Slave, and Four Years in the White House in 1868, partly to help Mrs. Lincoln financially and partly to counter criticism of Mrs. Lincoln. Keckley did not foresee the overwhelming public disapproval for publishing personal details about Mrs. Lincoln and White House private life; it led to the end of her dressmaking career as well as condemnation from the Lincoln family. She left Washington in 1892 to teach domestic skills at Wilberforce University, but ill health forced her to return and spend her final years in the Home for Destitute Women and Children, which she had helped to establish. She died there after a stroke in 1907.

Original passage below, taken from: Wade, Peter. Race and Ethnicity in Latin America. London and Chicago: Pluto Press, 1997. But it is no coincidence that just as abolitionist opinion gained dominance in Europe, making the institutionalized inferiority of blacks morally insecure, theories [claiming to be 'scientific'] began to emerge that could justify the continued dominance over blacks (not to mention Native Americans, Asians and Orientals) in terms of supposedly innate and permanent inferiority and now with the full power of scientific backing (Wade, 1997: 11). Paraphrase: Although the abolitionist cause weakened the European public's acceptance of slavery, pseudo-scientific theories were advanced which argued that non-whites were inherently inferior to whites. This meant that even while institutionalized racism lost its support, ideological racism was able to secure the continued oppression of non-whites (Wade, 1997: 11).

Explanation:

We are to find the percentage of single people given the data in the question.

Total number of people = 100 + 40 +60 + 200 + 60 + 40 = 500

Total number of single people = 100 + 200 = 300

The percentage of single people = [(total singles) / (total number of people)] * 100

= 300/500 x 100

= 0.6 x 100

= 60 percent.

60 percent of this population are single people

Explain how advances in scientific knowledge have influenced society.

Answers

Answer:

Advances in scientific knowledge have led to changes in society. As scientific understanding increases, changes in technology occur. These changes have led to increased life expectancy, cures for diseases, use of new energy sources, changes in warfare, increased pollution, and a larger gap between developed and developing countries. Some advances in scientific knowledge have led to negative consequences, such as an increase in pollution, but further advances in scientific knowledge can help remedy those situations.

Explanation:

Edge 2021 sample answer

Technology changes as our grasp of science grows. Increased life expectancy, disease cures, the use of new energy sources, modifications in warfare, increased pollution, and a wider gap between developed and developing nations are the results of these changes.

What is technology?

Technology is defined as the application of scientific knowledge to the objectives of human life that are practical, or, as it is frequently said, to the modification and manipulation of the environment that affects humans. The primary goal of technology, which combines tools to encourage development, use, and information exchange, is to simplify tasks and find solutions to many of humanity's problems.

Changes in society have been brought about by advances in scientific knowledge. Technology changes as our grasp of science grows. More life expectancy, disease treatments, the use of new energy sources, modifications in warfare, increased pollution, and a wider divide between developed and poor nations are the results of these changes. Although some scientific discoveries have had unfavorable effects, such an increase in pollution, future discoveries may assist to address those problems.

Thus, technology changes as our grasp of science grows. Increased life expectancy, disease cures, the use of new energy sources, modifications in warfare, increased pollution, and a wider gap between developed and developing nations are the results of these changes.

Answers

As the fourth pillar of government, the media should report the news impartially. They require proof before posting a story to influence news items without having to. All news should be confirmed many times before dissemination.

This is further explained below.

Media and sensation:

Generally, The capacity of the media to break fresh stories that grab the attention of millions of people is one of the key factors contributing to the media's increased effectiveness today.

Every media outlet works hard to be the first to break exciting news. This propensity has the drawback of exaggerating and distorting the information that is shared with the public.

This is thus because wealthy individuals, who in turn dominate politics and the government, also control the majority of the media. They either portray something significant as nothing and nothing as more serious, or the opposite.

Since the media is thought of as the fourth pillar of the government, it would be proper if they reported the news honestly and without bias. Before publishing a story, they want absolute evidence because when there is proof, they can influence the news articles without needing to.

Before accepting it for transmission, every piece of news should be verified at several stages to verify its veracity.
