Data were collected on the ages, in years, of the men and women enrolled in a large sociology course. Let the random variables M and W represent the ages of the men and women, respectively. The distribution of M has mean 20.7 years and standard deviation 1.73 years. The distribution of W has mean 20.2 years and standard deviation 1.60 years. Of all of those enrolled in the course, 54 percent are men and 46 percent are women. What is the mean age of the combined distribution of both men and women in the course?

Answers

Answer 1

Answer:

The mean age of the combined distribution of both men and women in the course is:

20.47 years.

Explanation:

a) Data and Calculations:

Random variable M = age of men

Random variable W = age of women

Distribution of                    M:                 W:

Mean =                            20.7 years     20.2 years

Standard Deviation =       1.73 years      1.60 years

Percentage of enrolled   54%                46%

Mean Age Proportion     11.178              9.292

Combined mean age =  20.47 (11.178 + 9.292)

b) Mean Age Proportion:

M = 20.7 * 54% =   11.178

W = 20.2 * 46% = 9.292

Total                     20.47

Answer 2

The mean age of the combined distribution of both men and women in the course is 20.47 years

Mean age of men , M = 20.7 years

Mean age of Women , W = 20.2 years

Percentage of Men = 54%

Percentage of Women = 46%

Recall, :

Mean, μ = np

The mean age of men in the distribution = (20.7 × 54%) = 11.178 years

The mean age of women in the distribution = (20.2 × 46%) = 9.292 years

The mean age of the combined distribution is :

11.178 + 9.292 = 20.47 years

Therefore, the mean age of the combined distribution is 20.47 years

Why might some people be opposed to the use of biotechnology?
A) It can lead to the development of resistant microorganisms.
B) It can lead to competition between modified and native organisms.
C) It can lead to the production of toxic materials.
D) All of the above

Answers

Answer: D) All of the above

Explanation:

Biotechnology has come a long way in the last 2 decades and has brought quite some good. But with that good came from bad as well as the potential for bad.

One of those is that in finding new ways to improve on biological processes, biotechnology could create resistant microorganisms that will affect humanity adversely until stronger medication is introduced.

Modified organisms will also compete with native organisms for dominance and will probably win due to enhancements which will affect the ecosystem. Toxic materials could also be produced and introduced into human food supply which would be very harmful.

A few years ago, a popular clothing store ran TV ads with people doing some amazing dancing. The dancers leaped high in the air and did flips over each other's backs. They were doing the Lindy Hop. The Lindy Hop has a long and interesting history. The Lindy Hop started in 1926 at the Savoy Ballroom in the Harlem neighborhood of New York City. It's a type of swing dance that grew from the earlier swing dances, the Breakaway and the Charleston. It's fast, fun, and full of spectacular moves. The Breakaway was renamed the Lindy Hop in 1927 in honor of Charles Lindbergh's famous flight across the Atlantic Ocean. As Lindy Hoppers tried to outperform each other, they invented new moves. In fact, the dance was banned from the main dance floor at the Savoy because the dancing took up too much space. But soon everyone wanted to dance the Lindy, so the owners of the club moved it to the main dance floor. The dance took off, and the famous back-to-back move was invented in which the woman flips over the man's back. After World War II (1939–1945), jazz music developed from swing into bebop that people no longer danced to. But in the 1980s, the Lindy Hop had a revival. Now there are Lindy Hop dance clubs in many cities in the United States and Europe. Read this essay and type the topic and thesis statement in the space provided.

“Fort Ross, located about 90 miles north of San Francisco, marked the southern-most limit of Russian territory in North America. It was founded in 1812 by the Russian-American Company as an agricultural colony to feed Russian fur trappers in Alaska. With a population of 250 at its peak, Fort Ross was actually the central hub for a number of even smaller outposts as far south as Bodega Bay and the Farallon Islands, located 40 miles north and 18 miles west of San Francisco, respectively. The Russians dismantled the colony in 1841. But Mexico was still worried about the threat of Russian expansion in their land, so they invited Anglo-American settlers to California as a buffer against Russian expansion from Alaska. The Mexican government also considered inviting Chinese colonists and Irish famine refugees to California.” Source: The Mental Floss History of the United States by Erik Sass
Does this information support or refute the view that American dominance then annexation of California was in the best long term interests of the North America. Explain your reasoning.

Answers

Answer:

Yes, it supports that view because Mexico which is a country in North America did not want Russia, a European country to dominate North America. Therefore, they encouraged the American annexation of California.

Explanation:

The excerpt says that the Russians already had Fort Ross in their possession and that they were expanding as seen in their other smaller outpost which extended far into the Farallon Islands. The population was also increasing as the territory expanded. The Mexicans who are North Americans wanted to protect the territory from Russian domination.

For that reason, they encouraged the Anglo-Americans to move into California. So, this annexation of California was actually in the best long term interests of North America.
