One example in the film Scream (1996) that brings a surprising amount of comedy is the scene where Randy Meeks (played by Jamie Kennedy) is explaining the "rules" of a horror movie to a group of teenagers at a party.

As he goes through the list of horror movie cliches, such as "don't have sex," "never say 'I'll be right back,'" and "never assume the killer is dead," the absurdity of the rules becomes increasingly clear, and the humor of the situation becomes more and more apparent.

Randy's
deadpan delivery and the characters' reactions to his speech add to the comedic effect of the scene. Despite being a horror film, Scream uses humor to subvert genre expectations and keep the audience engaged in a unique way.

For more than twenty-five years, the congregation of the Westboro Baptist Church has pick- eted military funerals. Church members believe that God hates the United States, specifically its military, for its tolerance of homosexuality. The picketing has also condemned the Catholic Church for scandals involving its clergy. At the funeral of Marine Corporal Matthew Snyder, picketers held up signs that said, "Thank God for Dead Soldiers, Doom Nations," "America Is Doomed," "Prieand "Youhe protest was peaceful and lasted for about thirty minutes before the funeral began. In Snyder v. Phelps, the Supreme Court ruled that the protest was protected by the Constitution.
A. Identify a provision of the Constitution that is common to Snyder v. Phelps (2011) and Schenck v. United States (1919). B. Explain why the facts of Schenck v. United States led to a different holding in Snyder v. Phelps. C. Describe an action that city or state government officials who disagree with the holding in Snyder v. Phelps could take to limit its impact.

Answers

A. Both Snyder v. Phelps and Schenck v. United States involve First Amendment free speech protections.

What did this involve?

B. Schenck v. United States involved speech that presented a clear and present danger to national security during wartime, whereas Snyder v. Phelps involved speech on a matter of public concern (the military and homosexuality) in a public space, which is given greater protection under the First Amendment.

C. City or state officials who disagree with the holding in Snyder v. Phelps could enact reasonable time, place, and manner restrictions on picketing at funerals, as long as those restrictions do not target the content of the speech.

Additionally, officials could potentially use their authority to create designated protest zones that balance the right to free speech with the privacy and emotional needs of funeral attendees.

An urban economist wishes to test the claim that the distribution of U.S residents in the US is different today than in 200. In 200, 19% of the population of the US resided in the Northeast, 22.9% resided in the Midwest, 35.6% resided in the South, and 22.5% resided in the West. The economist randomly selects 1500 households in the US and obtains the following.

Northeast: 272
Midwest: 303
South: 564
West: 359

Is there convincing evidence that the distribution of US residents in the US is different today than in 2000? Preform an appropriate test of significance to test the economist's claim at a .01 significance level.

Answers

We have convincing evidence to suggest that the distribution of US residents in the US is different today than in 2000 at a 0.01 significance level.

What is the explanation for the above response?

To test whether the distribution of US residents in the US is different today than in 2000, we can use a chi-square goodness-of-fit test. The null hypothesis is that the observed distribution is the same as the expected distribution from 2000, and the alternative hypothesis is that the observed distribution is different from the expected distribution.

We can calculate the expected number of households in each region under the null hypothesis as follows:

Expected Northeast = 1500 * 0.19 = 285

Expected Midwest = 1500 * 0.229 = 344.85

Expected South = 1500 * 0.356 = 534

Expected West = 1500 * 0.225 = 337.5

We can use the formula for the chi-square test statistic:

χ² = Σ (observed - expected)² / expected

where the sum is taken over all categories.

Using the observed and expected values from above, we can calculate:

χ² = [(272 - 285)² / 285] + [(303 - 344.85)² / 344.85] + [(564 - 534)² / 534] + [(359 - 337.5)² / 337.5]

= 11.841

The degrees of freedom for this test are (4-1) = 3.

Using a chi-square distribution table with 3 degrees of freedom and a significance level of 0.01, the critical value of χ² is 11.345. Since our calculated χ² value of 11.841 is greater than the critical value of 11.345, we can reject the null hypothesis.

Therefore, we have convincing evidence to suggest that the distribution of US residents in the US is different today than in 2000 at a 0.01 significance level.

4. Compare a baby's concept of the world to a three-year-old's concept of the
world

Answers

A baby's concept of the world, typically in the first few months of life, is limited to their immediate sensory experiences. They rely heavily on their senses of touch, taste, smell, sight, and sound to explore and understand the world around them.

What is the concept?

Their concept of the world is primarily centered around their caregivers, basic needs (such as feeding, sleeping, and comfort), and the immediate environment they are in.

On the other hand, a three-year-old's concept of the world is more developed and expanded compared to a baby's. By the age of three, children have gone through significant cognitive, emotional, and social development. They have acquired more language skills and are able to express themselves more effectively. Their understanding of the world is broader and more complex, as they have started to make sense of their surroundings and interact with others.

Some key differences between a baby's concept of the world and a three-year-old's concept of the world include:

Language development: A three-year-old has a significantly greater vocabulary and language skills compared to a baby. They can understand and use more words to communicate their thoughts, feelings, and ideas. This allows them to have more meaningful interactions with others and better understand the world around them.

Lastly, Cognitive development: A three-year-old has a more advanced cognitive development compared to a baby. They can engage in simple problem-solving tasks, have a basic understanding of cause and effect, and can make simple connections between objects, events, and people in their environment.

The point where marginal cost equals $15 is at the production of the 7th pizza. Therefore, the firm should produce 7 pizzas.

What is the firm's shut-down price?

The firm's shut-down price is the price at which the firm is indifferent between producing and shutting down.

Using the table provided, we can calculate the missing values:

Variable Cost:

For 0 pizzas, the variable cost is $0.

For 1 pizza, the variable cost is $10.

For 2 pizzas, the variable cost is $12.

For 3 pizzas, the variable cost is $2.

For 4 pizzas, the variable cost is $1.

For 5 pizzas, the variable cost is $2.

For 6 pizzas, the variable cost is $3.

For 7 pizzas, the variable cost is $13.

For 8 pizzas, the variable cost is $16.

For 9 pizzas, the variable cost is $3.

For 10 pizzas, the variable cost is $6.

For 11 pizzas, the variable cost is $4.

Total Cost:

To calculate the total cost, we simply add the variable cost and the fixed cost for each level of output. The fixed cost is not given in the table, so we cannot calculate the total cost.

Average Variable Cost:

To calculate the average variable cost, we divide the variable cost by the level of output.

For example, the average variable cost for 1 pizza is $10/1 = $10.

Average Fixed Cost:

To calculate the average fixed cost, we divide the fixed cost by the level of output.

The fixed cost is not given in the table, so we cannot calculate the average fixed cost.

Average Total Cost:

To calculate the average total cost, we add the average variable cost and the average fixed cost.

The average fixed cost is not given in the table, so we cannot calculate the average total cost.

Marginal Cost:

To calculate the marginal cost, we find the difference in total cost between two consecutive levels of output, and divide by the difference in output.

For example, the marginal cost of producing the 3rd pizza is (Total Cost of 3 pizzas - Total Cost of 2 pizzas) / (3 - 2) = ($12 - $10) / 1 = $2.

Total Revenue:

The total revenue for each level of output is given as $15 times the level of output.

Marginal Revenue:

The marginal revenue for each level of output is $15.

Profit:

To calculate the profit, we subtract the total cost from the total revenue.

The fixed cost is not given in the table, so we cannot calculate the profit.

The firm should produce pizzas up to the point where marginal cost equals marginal revenue.

This is the point where the firm maximizes its profit. From the table, we can see that the marginal cost is increasing as output increases, while the marginal revenue remains constant at $15.

In this essay, I will discuss the health issues one may get from smoking. To start with I will explain how smoking started. There are many types of smoking but the number one most smoked substance is tobacco. Smoking goes back to 5000 BC and would be used in rituals. Around the time of the Revolutionary War, tobacco goods started to become very popular in the US. Cigarette smoking is the leading cause of preventable death in the United States. Smoking causes more deaths yearly than HIV, illegal drug use, alcohol use, motor vehicle accidents, and firearm-related incidents. Smoking tobacco causes 90% of all lung cancer deaths, more than women with breast cancer.Smoking can cause lung disease by damaging your airways. Tobacco harms every organ in your body. Smoking tobacco introduces not only nicotine but also more than 5,000 chemicals, including numerous carcinogens (cancer-causing chemicals), into your lungs, blood, and organs. It has been proven that smoking tobacco can shorten your lifespan.Some examples of diseases you can get from smoking are Lung Cancer, COPD (chronic obstructive pulmonary disease), Heart Disease, Stroke, and Asthma. Those are just some of the many conditions you can get.Lung Cancer Compared to other cancers, lung cancer claims the lives of most individuals. Nearly 90% of lung cancer cases are caused by cigarette smoking, making it the leading lung cancer risk factor. There is a one in five possibilities that you will still be living five years after being diagnosed.COPD (chronic obstructive pulmonary disease) Obstructive pulmonary illness (COPD) makes breathing difficult. Early death and severe lasting effects are the results. When COPD first begins to limit one's ability to be active, such as when playing with a grandchild, it typically grows worse, making even simple tasks like walking to the mailbox or going up a couple of steps difficult or impossible. People may become restricted to their homes, unable to have their desires or visit friends. Smoking cigarettes contributes to 85% to 90% of all cases of COPD. The sixth most common cause of mortality in the US is COPD.Heart diseases Nearly every function in your body, including your heart, is harmed by smoking. Smoking can result in challenges and artery pressure, which reduces the amount of blood and oxygen reaching your heart. The rate of cardiac disease also dropped as cigarette use declined in the United States. However, the leading cause of mortality in the US continues to be heart illness.Stroke Smoking may lead to a stroke because it changes the blood vessels. When your brain's temporary blood flow is cut off, a stroke occurs. Because of the lack of air, brain cells begin to weaken. The effects of a stroke can include death, paralysis, speech difficulties, and changed brain function. Stroke is the fifth most common cause of death and plays an important role in adult damage in the United States.Asthma Asthma is a chronic lung condition that makes it more difficult to "breathe," or send oxygen in and out of your airways. Cigarette smoke can cause quick and serious attacks of asthma because it affects the airways. More than 25 million people in the United States suffer from asthma, a severe medical disease. It only gets worse when you smoke.Those are just some of the effects smoking can cause. Here is more, it can increase tooth loss and gum damage, lower the immune system, increase diabetes, premature aging, stained teeth, and bad breath.As a result of all that I've stated, smoking can lead to lifelong illnesses or even death.
