Hydrochlorofluorocarbons (HCFCs) are human-made chemicals that have been used as temporary replacements for chlorofluorocarbons (CFCs) in refrigerants because they decompose more readily in the atmosphere and thus pose less of a threat to Earth’s protective ozone layer. Levels of HCFCs have been measured in the stratosphere, and the concentrations of many different HCFCs have been steadily increasing since the mid- to late 1990s.

One important drawback of the use of HCFCs as a replacement for CFCs is that HCFCs:

a) biomagnify in food chains in the Arctic ecosystem

b) combine with water vapor to form acid precipitation

c) are greenhouse gases that contribute to climate change

d) react with carbon monoxide ( CO ) to form ozone in the troposphere

The following are used to calculate the requirement.

Explanation:

In the simple random sample, probability that at least 30 percent of women in the sample will not meet the age requirement is 0.0322.

In stratified random sampling, proportion of women who does not meet the age requirement is = 30 by 100 = 0.30

Standard error of proportion, Cp = Vp ( 1 minus p) by n = V 0.3 (1 minus 0.3) by 100 = 0.0458

Standard error of proportion = 0.0458

Thus, the probability that at least 30 percent of women in the sample will not meet the age requirement is higher for stratified random sampling.

So, a woman who does not meet age requirement is more likely to be selected with a stratified random sample than with a simple random sample.

The sampling distribution of the sample mean is a distribution of all possible sample means that could be obtained from a given population.

In this case, you're considering random samples of 50 students from the population of all students in honors biology classes. The population distribution of completion times has a mean of 70 minutes and a standard deviation of 26.5 minutes.

The mean of the sampling distribution of the sample mean is equal to the mean of the population. Therefore, the mean of the sampling distribution of the sample mean is equal to the population mean (μ), which is 70 minutes in this case.

The standard deviation of the sampling distribution of the sample mean, also known as the standard error, is given by the population standard deviation divided by the square root of the sample size.

Answer:

double a;

double b;

double distance = Math.sqrt( (Math.pow(a, 2) + Math.pow(b, 2));

System.out.println("The distance is: " + distance);

Explanation:

The code snippet is written in Java.

First, variable a is declared as a type of double and variable b is also declared as a type of double.

The given formula for the distance is:

√(a² + b²)

So we use the inbuilt function of Java to calculate the power and the square root.

Math.sqrt is to find the square root and it returns a value of type double.

Math.pow is use to calculate the value of a² and b².

a² = Math.pow(a, 2)

b² = Math.pow(b, 2)

Then Math.sqrt is applied to the sum of Math.pow(a, 2) and Math.pow(b, 2), the value is assigned to distance of type double.

The value of distance is now displayed to the user:

System.out.println("The distance is: " + distance);

Explanation:

There are several important factors for the economic growth and globalisation of Orlando Florida,

The first is the medical facilities in Orlando. Orlando offers one of the best medical facilities in United States and many patients visit this place just to get medical treatment.

The second aspect is the number of visitors that Orlando attracts throughout the year

Also Orlando has seen the highest job growth for 2015 till 2018 for any other US state and most of the fortune 500 companies have their operations in Orlando

The refusal of Fed would lead to increase in job creation and growth leading to increase in popularity of the president.

Explanation:

The federal reserve refused to increase the rate of interest which led to the increase in the creation of the jobs and more employment opportunities for the people of the economy.

This would lead to the increase in the growth and the development of the country and the economy. Thus there would be increase in the popularity of the President because during that tenure the economy is seeing growth and development.

Walter's statement about African Americans being "the world's most backward race" does not reflect his true beliefs but underscores the historical prejudices and systemic challenges faced by African Americans. Leaders like Du Bois and Garvey rejected such stereotypes, emphasizing strength, self-respect, and potential within the Black community.

When Walter refers to African Americans as "the world's most backward race of people," it seems he is expressing a sentiment that aligns with a problematic stereotype stemming from historical prejudice and systemic disenfranchisement. However, given the context provided, Walter does not actually believe this; rather, it appears to be a critique of the systemic issues that have unjustly characterized African Americans this way. Figures like W. E. B. Du Bois and others sought to challenge such notions by advocating for the acknowledgment of the real socio-economic obstacles African Americans faced and the unjust prejudices that contributed to such a disparaging view.

The content quotes highlight the complexities and different perspectives within the African American community regarding their status and path forward. Du Bois and Garvey, among others, emphasized the importance of self-respect, self-help, and the rejection of submission to the dominant culture's devaluation of Black people. The critical perspective extends to challenge the distortion of facts and the role of stereotypes in perpetuating systemic racism. They argue for a recognition of the collective strength and potential of Black people to rise above the obstacles and prejudices placed in their way. Therefore, such a statement is not a genuine belief but a reflection of the deep-rooted societal issues that figures like Du Bois were seeking to address and overcome. It's a portrayal of the external view forced upon African Americans, not an expression of internal self-perception or an endorsement of that erroneous and harmful stereotype.
