The height of learners (in centimetres) at a high school can be described by the N (174,50; 47,61) distribution.


4. 1 If 1000 learners are randomly selected from the school, how many of them would you expect to have a height of


4. 1. 1 less than 160,0 centimetres?

Answers

Answer 1

we would expect approximately 381 learners out of the randomly selected 1000 learners to have a height less than 160.0 centimeters.

To determine how many learners would be expected to have a height of less than 160.0 centimeters, we need to calculate the cumulative probability using the given normal distribution parameters.

The parameters of the normal distribution are as follows:

Mean (μ) = 174.50

Standard Deviation (σ) = 47.61

First, we need to standardize the value of 160.0 centimeters using the formula:

Z = (X - μ) / σ

Z = (160.0 - 174.50) / 47.61

Z = -0.305

Next, we find the cumulative probability associated with this standardized value of Z using a standard normal distribution table or a statistical calculator. Let's assume the cumulative probability is P(Z < -0.305) = 0.3815.

Finally, we multiply the cumulative probability by the total number of learners to find the expected number of learners with a height less than 160.0 centimeters.

Expected number = P(Z < -0.305) * 1000

Expected number = 0.3815 * 1000

Expected number ≈ 381

B. influenced by an earlier era.
C. influenced by Romanticism.
D. an extension of Romantic ideals.

Answers

The artistic trends of the early twentieth century can best be characterized as a reaction against Romanticism (option a).

The artistic trends of the early twentieth century can be best characterized as a reaction against Romanticism (Option A). During this time period, artists and intellectuals sought to challenge and break away from the romantic ideals that dominated the late 18th and 19th centuries. Romanticism emphasized emotion, individualism, and a glorification of nature, often depicting idealized and fantastical scenes.

In contrast, the artists of the early twentieth century embraced new approaches and movements that aimed to reject the sentimental and idealized nature of Romanticism. They sought to challenge traditional artistic norms and explore new forms of expression. This period witnessed the rise of various avant-garde movements, such as Cubism, Futurism, Dadaism, and Surrealism.

These movements rejected the romantic emphasis on the subjective experience and instead focused on innovative techniques, abstract forms, and unconventional subject matters. They embraced a more fragmented and experimental approach, challenging the notion of a singular, unified perspective. Artists during this time also drew inspiration from the rapid social, political, and technological changes happening in the world, reflecting the fragmented and chaotic nature of the modern era.

In summary, the artistic trends of the early twentieth century were a reaction against Romanticism, as artists sought to break away from its sentimental and idealized nature, and instead embraced new movements that challenged traditional norms and explored innovative forms of expression.

Answer:

As a part of my duty as a president of ‘disciplinary society’ (a joy that I have had for past five years), I have been asked, to write a report suggesting the changes I think are needed to maintain a healthy decorum for young children and teenagers in school premises. After having some professional surveys, we have discovered that there are five sites which are prompting ailing environment in our prestigious institution.

Potently, ​ ​unhealthy​ food​ is offered in five main cafeterias of school with lack of hygiene products. ​ ​Junk food might taste good, but eating too often in your diet can have negative​ ​effects on your overall health. ​ ​A​s ​these diets are high in​ ​saturated fat and calories and​ ​low in nutrients​ and​ can ​​contribute to illness and obesity. According to the​ ​U.S. Department of​ ​Agriculture (USDA), if everyone adopted a healthier diet, it could prevent $71 billion in expenses associated with lost productivity, medical costs and premature deaths.

We can improve the situation by strong implications of some rules. For example, new menus might be introduced with less oily food. A program of regular exercises and guidance should be arranged on how to eat healthily and live a healthier life. Cafeteria must be modified to deliver a hygiene food and environment for students.

This would prove beneficial for both students and institution. Consequently, there would be fewer absences from school because of stomach upsets. Leading to a more alert mind leading to better concentration and academic performance. Generally, finding school more attractive.  The school would also benefit from an enhanced reputation and this would eventually increase the number of candidates as parents would become aware of the new regime.

Once again, we hope that the recommendations from this report are taken seriously as there is clear need to invest in health sector to promote a healthy community to reduce health issues among students.

5. Six people are in a room. Everyone shakes everyone elsc's hand one time. How many

Answers

There are 15 handshakes in total. In order to solve combinatoric problems like this one, we need to remember to identify the values of n and k and apply the formula accordingly.

In the problem of handshakes, six people are in a room and everyone shakes everyone else's hand one time. The problem is asking how many handshakes there are in total. In order to find out, we need to use combinatorics and apply the formula of n choose 2 where n is the number of people in the room. 

The formula for n choose k is given by (n!)/(k! (n−k)!), which is a combination formula. 

The formula n choose 2 simplifies to (n(n-1))/2. This is because we are choosing two people from n people, which is equal to n choose 2, and since the order of the handshake doesn't matter we divide the result by 2 to eliminate duplicates. The combination formula is used to solve problems involving selecting items or arranging objects in a specific order.

We can apply this formula to the given problem as follows: 

Number of Handshakes = nC2 = (n(n-1))/2 = (6 × 5)/2 = 30/2 = 15.

There are 15 handshakes in total. In order to solve combinatoric problems like this one, we need to remember to identify the values of n and k and apply the formula accordingly.

the pole star as a navigational device was useless

Answers

The statement that the pole star as a navigational device was useless is incorrect. The pole star, also known as Polaris, has been widely used throughout history as a reliable navigational aid, particularly in the northern hemisphere.

The pole star is located close to the celestial North Pole and appears relatively fixed in the sky, making it a valuable reference point for determining direction and navigation.

Its position can be used to establish latitude, as it aligns with the Earth's axis of rotation. For centuries, sailors, explorers, and travelers have relied on the pole star to navigate at sea or across land. By observing the angle between the horizon and the pole star, sailors could determine their latitude and navigate along a desired course.

While the pole star may not be the sole navigational device used in modern times due to the availability of advanced technologies such as GPS, it still holds significance in celestial navigation and has proven to be a valuable tool for explorers and navigators throughout history.

Power and Politics

A collective group of people with general goals is how organizations are first established and built. In order the goals to be achieved people will need to work together and behave in a way that is governed by rules, regulations, policies and other methods that have been established by the organization. This is normally accomplished through the process of influencing behaviors. Power is a task of ties of give-and-take and politics is the establishment and process of the application of power. “Power can be defined as the capacity of one party to influence the other parties and to act as first party desires. Power can …show more content…

The art of being a good leader includes good communication on a regular basis with their staff, be objective to ideas and listen to the staff’s views and try to never act superior. In addition, good leaders always try to include the staff or team in the decision making process. An example of relationship of power and politics is Toyota. At the end of March, 2006 Toyota earned a substantial profit which totaled approximately one trillion yen; the wages of Japanese workers have been decreasing the last seven years continuously. The management of the company used their power in a political manner and did not share the profit with their employees (Information on a "February 11 Aichi Toyota General Action", 2006). This is an example of direct and indirect relationship between power and politics at the level of management and leadership.

Conclusion

Without power the manager or department head would be a figure occupying space. In the game of power and politics management and the leader of the organization have a significant place. The practice of leadership and management are also unified with the power because the main goal of power and leadership is the same; that of influencing others, based to the behavior of the leadership.
