What is the sum of the polynomials (8x2-9y2-4x)+(x2-3y2-7x).

Answer:

\(x = -1, y = \frac{8}{3}\)

Explanation:

1. Isolate for x in 2x + 3y = 6:

x = \(\frac{6-3y}{2}\)

2. Plug x into the second equation:

-4(  \(\frac{6-3y}{2}\)) + 3y = 12

3. Solve for y:

9y - 12 = 12

9y = 24

y = \(\frac{8}{3}\)

4. Plug y into the first equation:

2x +3( \(\frac{8}{3}\)) = 6

5. Solve for x:

2x + 8 = 6

2x = -2

x = -1

Answer:

To find the 95% confidence interval for the true mean breaking strength of all cables produced by the manufacturer, we can use the formula:

Confidence Interval = Sample Mean ± (Critical Value * Standard Error)

First, let's calculate the standard error, which is the standard deviation divided by the square root of the sample size:

Standard Error = Standard Deviation / √(Sample Size)

= 92 / √(90)

≈ 9.685

Next, we need to determine the critical value corresponding to a 95% confidence level. Since the sample size is large (n > 30), we can use the z-table. The z-value for a 95% confidence level is approximately 1.96.

Now we can calculate the confidence interval:

Confidence Interval = Sample Mean ± (Critical Value * Standard Error)

= 1700 ± (1.96 * 9.685)

Lower Limit = 1700 - (1.96 * 9.685)

≈ 1679.69

Upper Limit = 1700 + (1.96 * 9.685)

≈ 1720.31

Therefore, the 95% confidence interval for the true mean breaking strength of all cables produced by this manufacturer is approximately (1679.7, 1720.3). The lower limit is 1679.7 pounds, and the upper limit is 1720.3 pounds.

The conflict of character versus nature is an external conflict in literature. It is frequently represented as a person battling the environment, including natural disasters, wild animals, or the natural world's destructive side.

In The Grasshopper and The Ant, this conflict ties into the story's theme in a variety of ways.

To begin with, the narrative depicts how nature, in this case, the environment, can have an impact on our lives. Throughout the story, the grasshopper avoids the ant's attempts to prepare for the winter, preferring to sing and dance.

When the winter arrives, the grasshopper is caught unprepared and ends up hungry and freezing. The story's moral teaches readers that being ill-prepared can be disastrous, especially when it comes to nature. It also highlights the importance of being proactive in preparing for the worst.

Another way the character versus nature conflict ties into the story's theme is by highlighting the ant's perseverance and hard work. Despite the harsh circumstances, the ant remains determined and dedicated to his goal of preparing for the winter. This serves as an inspiration to readers to persevere even in the most challenging situations.

Furthermore, the story shows how nature can be both harsh and benevolent. The grasshopper suffers due to the harsh winter, but the ant's hard work also pays off in the end when he can enjoy the fruits of his labor. This teaches readers that nature can both give and take away.

Finally, the conflict of character versus nature in The Grasshopper and The Ant serves to teach readers about the importance of balance. The ant's hard work and preparation are admirable, but the grasshopper's love of life and music is also crucial. This emphasizes that while it's essential to be prepared, it's also necessary to enjoy life and not take it for granted.

Explanation:

Answer:

To find a 90 percent confidence interval for the population mean of the workers' monthly income in the factory, you can use the formula:

Confidence interval = sample mean ± (critical value * standard error)

First, you need to find the critical value corresponding to a 90 percent confidence level. Since the sample size is large (n = 100), we can use the Z-distribution. For a 90 percent confidence level, the critical value is approximately 1.645.

Next, you calculate the standard error, which is the standard deviation of the sample divided by the square root of the sample size:

Standard error = standard deviation / √(sample size)

Standard error = 20 / √(100)

Standard error = 20 / 10

Standard error = 2

Now you can substitute the values into the confidence interval formula:

Confidence interval = 400 ± (1.645 * 2)

Calculating the confidence interval:

Lower bound = 400 - (1.645 * 2) = 400 - 3.29 = 396.71

Upper bound = 400 + (1.645 * 2) = 400 + 3.29 = 403.29

The 90 percent confidence interval for the population mean of the workers' monthly income is approximately 396.71 to 403.29 birr.

Explanation:

Interpretation: We are 90 percent confident that the true population mean of the workers' monthly income in the factory falls within the range of 396.71 to 403.29 birr. This means that if you were to take multiple samples and calculate confidence intervals for each sample, approximately 90 percent of those intervals would contain the true population mean.

The standard deviation of the ages of this breed of dog is approximately 4.4 years.

To find the standard deviation, we can use the concept of z-scores and the cumulative distribution function (CDF) of a standard normal distribution. Let's denote the average age as μ (mu) and the standard deviation as σ (sigma).

Given that the average age of the breed is 19.5 years, we can set μ = 19.5. We are also given that 20% of the dogs are older than 22.6 years. Using the z-score formula, we can calculate the z-score corresponding to this percentile:

z = (x - μ) / σ

Where x is the given value (22.6 years) and z is the z-score. Rearranging the formula, we can solve for σ:

σ = (x - μ) / z

Plugging in the values, we have:

σ = (22.6 - 19.5) / z

To find the z-score corresponding to the 20th percentile, we can use the inverse CDF of the standard normal distribution. Using statistical software or a z-table, we find that the z-score corresponding to the 20th percentile is approximately -0.84.

Substituting the values, we get:

σ = (22.6 - 19.5) / -0.84 ≈ 3.7 / -0.84 ≈ -4.4

Read the excerpt from Votes for Women:

At the Seneca Falls Convention in July 1848, women like Lucretia Mott and Elizabeth Cady Stanton signed the Declaration of Sentiments, a document expressing their concerns about the role of women in the United States. For example, at the time married women could not own property, and the education and employment of women was limited. These women decided that to change the law, women needed to be able to vote. Some thought that peaceful methods were the best way for the Women's Suffrage Movement to obtain its goal, while others believed that a more aggressive strategy was necessary.

The peaceful approach in the Women's Suffrage Movement changed the United States over time. At first, there was resistance to the idea of women having the vote. Many believed that the practice of politics was masculine and men should vote on behalf of their wives and daughters. When African American men were granted the right to vote in the 15th Amendment, women of any race were not included. This decision discouraged many women, but they still organized themselves into groups, like the National American Woman Suffrage Association, in order to campaign for the vote. They argued that voting women would benefit society, and published newspaper articles and other literature about women's rights. From 1878 until 1920, the idea of women's suffrage was brought before Congress every year. In the meantime, women also campaigned for the vote in different states. During World War I, many women did jobs regularly done by men. Their contributions to the United States and the influence of Carrie Chapman Catt caused President Woodrow Wilson to finally support women's suffrage. The peaceful approach changed opinions over time and ultimately led to the 19th Amendment.

What reason does the author use to support the point that some thought peaceful methods were the best way for women to get the vote?

They changed people's opinions over time.

They led women to publish articles and other handouts.

They put women in positions of power and influence.

They responded to the public's resistance.
