Let time Y in years present the time before a major repair is required for a certain washing machine. Assume Y follows exponential distribution with a mean 5 years. (a) The machine is considered a bargain if it is unlikely to require a major repair before the sixth year. What's the probability that no major repair is needed before the sixth year? (b) What is the probability that a major repair is required in the first year? (c) Suppose after the repair, the washing machine is considered as a "new" one. It may require another major repair after some random time, which follows the same exponential distribution. Given a time duration of 10 years, what is the probability that this washing machine is repaired for twice?

Answers

Answer 1

(a) The probability of no major repair before the sixth year is [tex]1 - e^(-6/5)[/tex].(b) The probability of a major repair in the first year is [tex](1/5) * e^(-1/5)[/tex].

(c) The probability of the washing machine being repaired twice within a 10-year duration is [tex](1/5) * e^(-5/5)[/tex].

(a) To find the probability that no major repair is needed before the sixth year, we need to calculate the cumulative distribution function (CDF) of the exponential distribution with a mean of 5 years at the sixth year.

The formula for the CDF of the exponential distribution is given by[tex]P(Y \leq y) = 1 - e^(-y/\mu)[/tex], where y is the time duration and μ is the mean.

In this case, y = 6 years and μ = 5 years. Plugging these values into the formula, we get:

[tex]P(Y \leq 6) = 1 - e^(-6/5)[/tex]

(b) To find the probability that a major repair is required in the first year, we need to calculate the probability density function (PDF) of the exponential distribution at the first year. The PDF of the exponential distribution is given by[tex]f(y) = (1/\mu) * e^(-y/\mu).[/tex]

In this case, y = 1 year and μ = 5 years. Plugging these values into the formula, we get:

[tex]f(1) = (1/5) * e^(-1/5)[/tex]

(c) Given a time duration of 10 years, we want to find the probability that the washing machine is repaired twice.

Since the time between repairs also follows an exponential distribution with a mean of 5 years, we can use the memorylessness property of the exponential distribution.

The probability that the washing machine is repaired twice within a 10-year duration is equal to the probability of a major repair occurring in the first 5 years, which can be calculated using the PDF of the exponential distribution.

In this case, y = 5 years and μ = 5 years. Plugging these values into the formula, we get:

[tex]f(5) = (1/5) * e^(-5/5)[/tex]

Why is the family considered the basic unit of society? Explain

Answers

Answer:

It's True that Family is the basic unit of the Society.

Explanation:

The Sociologists are interested in the relationship between the institution of marriage and the institution of family because families are the most basic social unit upon which society is built, but also because marriage and family are linked to other social institutions such as the economy, government, and religion.

Essentially, Family is the Backbone of the Society.

Family is a socially recognized group (mostly joined by blood, marriage, cohabitation, or adoption) that forms an emotional connection among its members and that serves as an economic unit of society.

Sociologists identify different types of families based on how one enters into them.

A family orientation refers to the family into which a person is born.

A family of procreation describes one that is formed through marriage. These distinctions have cultural significance related to issues of lineage.

Therefore, It's True that Family is the basic unit of the Society.

Answer:

The family unit helps each member learn about and get used to social roles. Each member holds a specific function or social role in the family

According to the authors of your text, people are likely to quickly categorize people they have just met. This is due to people's reliance on______________.

Answers

According to the authors of the text, people are likely to quickly categorize people they have just met due to their reliance on stereotypes.

Stereotypes are mental shortcuts or generalizations that individuals use to quickly categorize and make sense of the social world. When meeting someone for the first time, people often rely on preexisting stereotypes based on factors such as gender, race, age, or occupation to form initial impressions.

These stereotypes, although often oversimplified and inaccurate, can influence the perceptions and expectations people have about others. They can shape judgments, behaviors, and interactions, leading to biases and potentially impacting the way individuals are treated.

It is important to recognize the limitations of relying solely on stereotypes and strive for more nuanced and individualized understanding of others. By challenging stereotypes and engaging in open-mindedness, people can foster greater understanding, empathy, and fairness in their interactions with others.

being a ___________, paul appealed the charges against him to caesar and was sent to rome.

Answers

Being a Roman citizen, Paul appealed the charges against him to Caesar and was sent to Rome.

As a Roman citizen, Paul exercised his right to appeal his case to Caesar, the Roman Emperor, in order to receive a fair trial. Paul, also known as the apostle Paul or Saint Paul, was a significant figure in early Christianity. He faced opposition and persecution for his teachings and missionary work.

The specific incident you are referring to is mentioned in the New Testament of the Bible, in the book of Acts. Paul was arrested in Jerusalem on false accusations brought by some Jewish religious leaders. As a Roman citizen, he used his legal privilege to appeal his case to Caesar, invoking his right to be tried in the highest court of the Roman Empire.

As a result, Paul was transported to Rome to appear before Caesar for his trial. This journey to Rome is described in detail in the book of Acts, where Paul faced various challenges, including a shipwreck, before eventually reaching Rome.

By appealing to Caesar, Paul sought both justice and an opportunity to spread the message of Christianity in the heart of the Roman Empire. His imprisonment and subsequent interactions in Rome played a significant role in the dissemination of his teachings and the growth of early Christianity.

Functions, including working memory, inhibition, and shifting, increase as the child grows older, up to about age 15. A parallel increase in processing  speed accompanies this increase in capacity

Processing speed refers to the rate at which an individual can process and respond to information. It involves the speed of cognitive processes, such as attention, perception, and decision-making. As children develop and mature, their neural connections become more efficient, allowing for faster processing of information. The parallel increase in processing speed is closely related to the growth of cognitive functions. As these functions become more developed and sophisticated, the ability to process and integrate information becomes quicker and more efficient. This improvement in processing speed facilitates more complex cognitive tasks and enhances overall cognitive performance.
