find the mean, variance, and standard deviation of the probability distribution.

Answers

Answer 1

For the given probability distribution, the mean is 5.75, the variance is approximately 24.37, and the standard deviation is approximately 4.94.

To find the mean of a probability distribution, we multiply each value of X by its corresponding probability and sum the results.

Mean = (-1 * 0.587) + (3 * 0.115) + (9 * 0.21) + (12 * 0.088) = 5.75

The variance of a probability distribution is calculated by taking the square of the difference between each value of X and the mean, multiplying it by the corresponding probability, and summing the results.

Variance = [(-1 - 5.75)^2 * 0.587] + [(3 - 5.75)^2 * 0.115] + [(9 - 5.75)^2 * 0.21] + [(12 - 5.75)^2 * 0.088] ≈ 24.37

The standard deviation is the square root of the variance.

Standard Deviation = √24.37 ≈ 4.94

Therefore, the mean of the probability distribution is 5.75, the variance is approximately 24.37, and the standard deviation is approximately 4.94. These measures provide insights into the central tendency, spread, and dispersion of the given probability distribution.

by 1700 the most populous colony in english america was

Answers

By 1700, the most populous colony in English America was Virginia.

The Colony of Virginia, also known as the Colony and Dominion of Virginia, was a British colony in North America that existed from 1607 until the American Revolution. It was one of the first colonies established in North America and served as the foundation for the establishment of other colonies such as Maryland, North Carolina, and South Carolina.

The colony was initially established by the Virginia Company of London, which was a joint-stock company chartered by King James I in 1606. The primary purpose of the colony was to provide a source of wealth for the company by discovering gold and silver deposits and to establish trade routes with the Native Americans for fur and other goods.

By the 1700s, Virginia had become the most populous colony in English America with a population of around 58,000 people. The economy of Virginia was largely based on agriculture, with tobacco being the primary cash crop. The colony relied heavily on the labor of enslaved Africans to cultivate the tobacco fields.

As the most populous and prosperous colony in English America, Virginia played a significant role in the American Revolution and the formation of the United States. Many of the founding fathers of the United States, such as George Washington, Thomas Jefferson, and James Madison, were born in Virginia and played key roles in the formation of the country's government.

The asymmetrical plan of the ____ from the Athenian Acropolis is unique. a. Temple of Athena Nike b. Parthenon c. Erechtheion d. Propylaia.

Answers

The asymmetrical plan of the Erechtheion from the Athenian Acropolis is unique.

Option c is the answer.

The Erechtheion, located on the Athenian Acropolis, features an exceptional asymmetrical plan, setting it apart from other structures in the vicinity. While the Parthenon and the Temple of Athena Nike exhibit symmetrical designs, the Erechtheion deviates from this convention.

The asymmetry of the Erechtheion's plan can be attributed to its purpose as a multi-functional temple dedicated to various deities. It comprises several distinct sections, each serving a different religious function. The east and west sides of the temple have differing column arrangements, with the east porch featuring six Caryatid columns (sculpted female figures serving as columns) and the west porch showcasing six Ionic columns. This contrast creates an asymmetrical facade that reflects the complexities of the temple's religious significance.

Furthermore, the Erechtheion's floor plan is also irregular due to the incorporation of sacred sites and natural features. It includes spaces for the worship of multiple gods, such as the cults of Athena Polias and Poseidon-Erechtheus. The presence of the olive tree, the sacred well, and the marks of Poseidon's trident further contribute to the unique arrangement of the Erechtheion.

In conclusion, while the Temple of Athena Nike, Parthenon, and Propylaia on the Athenian Acropolis follow more symmetrical designs, the Erechtheion stands out with its distinctive asymmetrical plan. This architectural peculiarity reflects its multifaceted religious purpose and incorporation of sacred elements, making it a remarkable and unique structure among the Acropolis monuments.

C) abuses of that discretion.
D) positive publicity about lowered discretion

Answers

The movement to limit the discretion of police officers is the result of the abuses of that discretion. What is discretion? Discretion is the ability to make choices based on your own personal judgment and beliefs. In the context of policing, this means that officers have the ability to use their own judgment when it comes to enforcing the law and interacting with the public. This can include things like deciding whether or not to make an arrest, using force to subdue a suspect, or deciding how to handle a situation. The problem with police discretion is that it can be abused. When officers use their discretion inappropriately, it can lead to misconduct, discrimination, and even brutality. This is why there has been a movement to limit the discretion of police officers in recent years. By doing so, the hope is that police will be held more accountable for their actions, and that there will be fewer instances of misconduct and brutality.

The Turkish-speaking tribal group that ultimately overthrew the Tang Dynasty in China were the Uighurs.

The Uighurs, a Turkic ethnic group, played a significant role in the downfall of the Tang Dynasty in China. The Uighurs were a nomadic people residing in the region known as Xinjiang, which is located in present-day northwest China. During the late Tang Dynasty, the Uighurs were enlisted by the Tang emperors as allies and mercenaries to help maintain control over the empire's vast territories.

However, over time, the Uighurs grew increasingly powerful and began asserting their own authority. In 755 CE, during the An Lushan Rebellion, the Uighurs seized the opportunity to rebel against the Tang Dynasty. They formed a military alliance with other rebel forces and launched attacks on the Tang capital, Chang'an, contributing to the collapse of the dynasty.

The Uighurs' involvement in the overthrow of the Tang Dynasty marked a significant turning point in Chinese history and led to a period of fragmentation and political instability.

Answers

Critics complain that the humanistic perspective fails to appreciate the role of unconscious processes and the influence of social and cultural factors on human behavior.

The humanistic perspective in psychology emphasizes the inherent worth and potential of individuals, focusing on their self-determination, personal growth, and subjective experiences. However, critics argue that this perspective overlooks important aspects of human behavior and psychology.

One criticism is that the humanistic perspective neglects the role of unconscious processes. Unlike psychodynamic theories, which highlight the significance of unconscious motivations and conflicts, humanistic psychology places less emphasis on the unconscious mind. Critics argue that by disregarding unconscious processes, the humanistic perspective fails to provide a comprehensive understanding of human behavior.

Additionally, critics suggest that the humanistic perspective tends to overlook the influence of social and cultural factors. While humanistic psychology values individual agency and personal experiences, it may not adequately consider the impact of external forces such as societal norms, cultural values, and social structures. Critics argue that a complete understanding of human behavior requires an acknowledgment of the interplay between personal experiences and the broader social and cultural contexts in which individuals are embedded.

In summary, critics contend that the humanistic perspective in psychology may be limited in its scope by not fully appreciating the role of unconscious processes and the influence of social and cultural factors on human behavior.

the effect of specialization and the division of labor is to make us:

Answers

The effect of specialization and the division of labor is to make us more efficient, productive, and interdependent.

Specialization refers to the process of individuals or groups focusing on specific tasks or areas of expertise, while the division of labor involves dividing a complex task or production process into smaller, specialized tasks performed by different individuals or groups.

By dividing work into specialized tasks, individuals can develop specific skills, knowledge, and expertise in their respective areas. This specialization allows individuals to become more efficient and proficient in their assigned tasks, as they can focus on developing expertise in a particular area rather than spreading their efforts across multiple responsibilities.

The division of labor enables individuals to work in a coordinated and interdependent manner. Each individual's specialized task contributes to a larger process or production system. As a result, the overall efficiency and productivity of the system can increase significantly. Tasks can be performed more quickly and with higher quality when individuals specialize and collaborate in their respective areas of expertise.

Specialization and the division of labor also facilitate technological advancements and innovation. When individuals focus on specific tasks, they have the opportunity to develop new techniques, tools, and technologies that further enhance productivity and effectiveness in their specialized field. This continuous improvement contributes to overall progress and economic growth.
