Step-by-step explanation:

Step 5:

To construct a box-and-whisker plot of the given wait times for the 11 volunteers, we need to arrange the data in ascending order. Here is the sorted list of wait times:

0, 5, 25, 46, 55, 70, 85, 103, 113, 120, 140

Now, let's construct the box-and-whisker plot using the following steps:

Step 1: Find the minimum and maximum values. The minimum value is 0, and the maximum value is 140.

Step 2: Find the median. The median is the middle value of the dataset. Since we have 11 data points, the median will be the 6th value, which is 70.

Step 3: Find the lower quartile (Q1). The lower quartile is the median of the lower half of the dataset. We have 5 data points in the lower half, so the lower quartile will be the median of these 5 values. The median of the lower half is the average of the 3rd and 4th values, which are 25 and 46. So, Q1 = (25 + 46) / 2 = 35.5.

Step 4: Find the upper quartile (Q3). The upper quartile is the median of the upper half of the dataset. We have 5 data points in the upper half, so the upper quartile will be the median of these 5 values. The median of the upper half is the average of the 8th and 9th values, which are 103 and 113. So, Q3 = (103 + 113) / 2 = 108.

Step 5: Calculate the interquartile range (IQR). The interquartile range is the difference between Q3 and Q1. IQR = Q3 - Q1 = 108 - 35.5 = 72.5.

Step 6: Draw the box-and-whisker plot. Using the minimum, Q1, median, Q3, and maximum values, we can draw the box-and-whisker plot as follows:

Here the line at 70 is showing the median of the given data.

Possible data is:

60, 150, 100, 130, 120, 70, 80, 90, 140, 110, 140

a. Comparing the shape of the two box-and-whisker plots: Unfortunately, without the exact box-and-whisker plots, I cannot provide a visual comparison of the shapes. However, you can compare the spread and symmetry of the two plots using the criteria mentioned earlier. Look at the lengths of the whiskers and the interquartile range (IQR) to assess the spread. Additionally, examine the position of the median to evaluate symmetry.

b. Identifying outliers in either data set: To identify outliers, we can examine the positioning of individual data points outside the whiskers in each box-and-whisker plot. Outliers are typically considered values that are significantly higher or lower than the rest of the data. Please check if there are any values in either data set that fall outside the whiskers.

c. Determining the most appropriate measure of central tendency: To determine the most appropriate measure of central tendency (mean, median, or mode) for each data set, consider the characteristics of the data. Assess the presence of skewness, outliers, and the nature of the data to guide your decision.

Answer:

B. The narrator's cousin holds on to the name of an old friend

Step-by-step explanation:

The major message or central idea that the narrator intends to get across while telling a story is referred to as the theme.

The subject of the story is cherishing and keeping memories for all time. This is demonstrated when the narrator's cousin remembers the name of an old friend.

Thus, the correct option is :

B. The narrator's cousin holds on to the name of an old friend

The question is Request clarification: Expert: Please provide the mentioned question. User: The map shows the route of a race. You are at Y, 6000 feet from the first checkpoint A. The second checkpoint B is located at the midpoint between A and the end of the race Z. The total race is 3.1 miles. How far apart are the two checkpoints?

Step-by-step answer

P Answered by PhD

From the question given above, we obtained the following information:

Y is 6000 ft from A (1st check point)

B (2nd check point) is the midpoint point between A and Z ( the end of the race)

Total race = 3.1 miles

1 mile = 5280 ft

Next, we shall express the total race in feet (ft).

This is illustrated below:

1 mile = 5280 ft

Therefore,

3.1 miles = 3.1 × 5280 = 16368 ft

Next, we shall determine the distance between the 1st check point (A) and the end of the race (Z)

This can be obtained as follow:

Total distance = 16368 ft

Distance between Y and A = 6000 ft

Distance between A and Z =?

Distance between A and Z = (Total distance) – (Distance between Y and A)

Distance between A and Z = 16368 – 6000 = 10368 ft

Finally, we shall determine the distance between the two check point (A and B) as follow:

Since B is midpoint between A and Z, therefore, we shall we shall divide the distance between A and Z by 2 in order to obtain the distance between the two checkpoints (A and B).

This is illustrated below:

Distance between A and Z = 10368 ft

Distance between the two check point (A and B) = 10368/2 = 5184 ft

Therefore, the distance between the two checkpoints (A and B) is 5184 ft.

Step-by-step explanation:

B. Yes, I would believe him, but I suppose I might still be doubtful since I find it difficult to accept someone who offers insufficient proof, but because the coastlines are connected, I can understand how they were once a single landmass.

Alfred Wegener, a German scientist, first put forth the concept of continental drift in 1915.

This hypothesis proposes that the landmasses originally formed a supercontinent known as Pangaea. After that, the land masses moved gradually to their present locations.

The Himalayan Mountains were formed as a result of the collision between the Indian Plate and the Eurasian Plate. The Indian Plate is still moving northwards and colliding into the Eurasian Plate, causing the continued uplift of the Himalayas. This process, known as continental collision, has been taking place for the last 50 million years and is still ongoing.

Answer:

-4+47.k, 3-35.k

Step-by-step explanation:

If a = 1, then gcd(1, 3) = 1.

If a > 1, then lets execute a single step of the Euclidean algorithm:

gcd (a+2, a) = gcd(a, (a + 2) mod a)

[Here, "x mod y" denotes the remainder of division of x by y.]

Now, clearly, (a + 2) mod a = 2, since a > 2. (a is

odd, and a 1, so a has to be at least 3.)

So, we have

gcd(a+2, a) = gcd (a, 2).

Continuing with the Euclidean algorithm, we get

gcd(a, 2)= gcd (2, a mod 2).

We know that a is odd, i.e., a mod 2 = 1, and clearly gcd (2, 1) = 1.

A) If a = 1, then gcd(1, 3) = 1.If a > 1, then lets execute a single step of the Euclidean a

Step-by-step explanation:

Obtaining a high school diploma is essential because it opens doors to a plethora of opportunities. A high school diploma is a basic educational requirement for most jobs, and it is also necessary to pursue higher education. Additionally, a high school diploma signifies that a person has developed critical thinking, communication, and problem-solving skills, making them more attractive to employers. In today's society, the job market is highly competitive, and having a high school diploma can provide a competitive edge. Moreover, a high school diploma is an accomplishment that provides individuals with a sense of pride and accomplishment, boosting their self-confidence and self-esteem.

Colleges and vocational schools differ in various ways. Colleges typically offer a broad range of academic programs, including liberal arts, sciences, and professional fields. On the other hand, vocational schools specialize in hands-on training in specific fields, such as technology, healthcare, and trades. Another difference is the length of time required to complete a program. College programs typically take longer to complete, ranging from two to four years, while vocational programs can take a few months to two years. Furthermore, the cost of attending a college is usually more expensive than vocational schools. However, a college degree may provide a higher earning potential in the long run.

Incorporating the two paragraphs above, obtaining a high school diploma is a prerequisite for pursuing higher education, such as college or vocational school. The difference between the two lies in the type of education and skills acquired. Colleges offer academic programs that lead to a degree and provide a broad range of knowledge in various fields. Vocational schools, on the other hand, offer specific training in a particular field, such as healthcare, technology, and trades. A high school diploma is necessary to enroll in either, and the choice of which to attend depends on an individual's interests, career goals, and financial resources. In conclusion, obtaining a high school diploma is a significant accomplishment that provides individuals with a competitive edge in pursuing their career and educational goals.

Side 1: 3x² -4x -1

Side 2: 4x - x² + 5

the length of two sides, 1 and 2, of the triangle = side 1 + side 2
