The stem-and-leaf plot displays data collected on the size of 15 classes at two different schools.

Mountain View School Seaside School
0 5, 8
9, 8, 2, 0 1 0, 1, 2, 5, 6, 8
8, 7, 6, 5, 5, 4, 4, 3, 1, 0 2 5, 5, 7, 7, 8
0 3 0, 6
Key: 2 | 1 | 0 means 12 for Mountain View and 10 for Seaside

Part A: Calculate the measures of center. Show all work. (2 points)

Part B: Calculate the measures of variability. Show all work. (1 point)

Part C: If you are interested in a smaller class size, which school is a better choice for you? Explain your reasoning. (1 point)

Answers

To calculate the measures of center, we need to find the mean and median for each school.

For Mountain View School:
Data: 0, 0, 0, 0, 1, 2, 3, 4, 4, 5, 5, 5, 5, 6, 7, 8, 8, 8, 9
Mean: (0 + 0 + 0 + 0 + 1 + 2 + 3 + 4 + 4 + 5 + 5 + 5 + 5 + 6 + 7 + 8 + 8 + 8 + 9) / 19
= 100 / 19
≈ 5.26

To find the median, we need to arrange the data in ascending order: 0, 0, 0, 0, 1, 2, 3, 4, 4, 5, 5, 5, 5, 6, 7, 8, 8, 8, 9.
The median is the middle value, which is the 10th value in this case.
Median: 5

For Seaside School:
Data: 0, 0, 0, 1, 1, 2, 2, 4, 5, 5, 5, 5, 6, 7, 7, 8, 8, 8, 9
Mean: (0 + 0 + 0 + 1 + 1 + 2 + 2 + 4 + 5 + 5 + 5 + 5 + 6 + 7 + 7 + 8 + 8 + 8 + 9) / 19
= 80 / 19
≈ 4.21

To find the median, we need to arrange the data in ascending order: 0, 0, 0, 1, 1, 2, 2, 4, 5, 5, 5, 5, 6, 7, 7, 8, 8, 8, 9.
The median is the middle value, which is the 10th value in this case.
Median: 5

Now let's calculate the measures of variability, specifically the range and interquartile range (IQR).

Range: The range is the difference between the largest and smallest values in the dataset.

For Mountain View School:
Range: 9 - 0 = 9

For Seaside School:
Range: 9 - 0 = 9

Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1) and measures the spread of the middle 50% of the data.

For Mountain View School:
Q1 = 3
Q3 = 7
IQR = Q3 - Q1 = 7 - 3 = 4

For Seaside School:
Q1 = 2
Q3 = 7
IQR = Q3 - Q1 = 7 - 2 = 5

To determine which school is a better choice for a smaller class size, we can consider both the mean and the median.

Both the mean and median for Mountain View School are higher than those for Seaside School. This suggests that, on average, the class sizes at Mountain View School are larger than those at Seaside School. Therefore, if you are interested in a smaller class size, Seaside School would be a better choice

Part A:

For Mountain View School:
- Median: The median class size is the middle value, which is 25.
- Mean: The mean class size is the sum of all the class sizes divided by the total number of classes, which is (29 + 28 + 28 + 27 + 25 + 24 + 24 + 23 + 21 + 20 + 19 + 18 + 15 + 13 + 10) / 15 = 21.27.

For Seaside School:
- Median: The median class size is the middle value, which is 20.
- Mean: The mean class size is the sum of all the class sizes divided by the total number of classes, which is (25 + 25 + 27 + 27 + 28 + 28 + 28 + 30 + 31 + 35 + 36 + 38 + 40 + 43 + 45) / 15 = 31.13.

Part B:

For Mountain View School:
- Range: The range is the difference between the largest and smallest values, which is 29 - 10 = 19.
- Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1). From the stem-and-leaf plot, we can see that Q1 is 20 and Q3 is 28. Therefore, the IQR is 28 - 20 = 8.

For Seaside School:
- Range: The range is the difference between the largest and smallest values, which is 45 - 25 = 20.
- Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1). From the stem-and-leaf plot, we can see that Q1 is 27 and Q3 is 38. Therefore, the IQR is 38 - 27 = 11.

Part C:

If you are interested in a smaller class size, Mountain View School is a better choice for you because it has a lower mean and median class size than Seaside School.

-3 (x- 4/5) ≤ 6 solve step by step

Answers

To solve for x, we need to isolate x on one side of the inequality. We can start by distributing the -3 on the left side of the inequality.

-3x + 12/5 ≤ 6

Next, we can subtract 12/5 from both sides of the inequality to isolate the variable term on the left side.

-3x ≤ 6 - 12/5

Simplifying the right side of the inequality:

-3x ≤ 30/5 - 12/5
-3x ≤ 18/5

Finally, we can divide both sides of the inequality by -3. Since we are dividing by a negative number, we need to reverse the direction of the inequality.

x ≥ -18/15

Simplifying:

x ≥ -6/5

Therefore, the solution for the inequality is x ≥ -6/5.

-3(x - 4/5) ≤ 6

Distribute the -3:

-3x + 12/5 ≤ 6

Subtract 12/5 from both sides:

-3x ≤ 6 - 12/5

Find a common denominator:

-3x ≤ 30/5 - 12/5

-3x ≤ 18/5

Divide by -3, remembering to flip the inequality since we are dividing by a negative number:

x ≥ -18/15

Simplify:

x ≥ -6/5

Describe how the data is dispersed in a box plot with the following data set: 25, 36, 21, 30, 20, 32, 38, 19, 36, 31, 26, 33, 27, 18, 24.

AND PLEASE ACTUALLY EXPLAIN/DESCRIBE!

Answers

In a box plot, also known as a box-and-whisker plot, the data is dispersed and represented visually to provide a summary of the distribution and key characteristics of the dataset. Let's describe how the data is dispersed in the box plot for the given data set: 25, 36, 21, 30, 20, 32, 38, 19, 36, 31, 26, 33, 27, 18, 24.

1. Median (Q2): The median represents the middle value of the dataset when arranged in ascending order. In this case, the median is around 27 or 28, as it lies between the values 27 and 30.

2. Lower Quartile (Q1): The lower quartile marks the boundary between the lower 25% of the data and the upper 75%. It is located approximately around 22 or 23, as it falls between the values 21 and 24.

3. Upper Quartile (Q3): The upper quartile marks the boundary between the lower 75% of the data and the upper 25%. It is located around 34 or 35, as it lies between the values 33 and 36.

4. Interquartile Range (IQR): The IQR is the range between the upper and lower quartiles (Q3 - Q1). In this case, the IQR is approximately 12 (35 - 23).

5. Whiskers: The whiskers represent the range of the data excluding any outliers. They extend from the lower quartile (Q1) to the minimum value and from the upper quartile (Q3) to the maximum value. However, in some cases, the whiskers can also be defined based on certain criteria, such as 1.5 times the IQR. Outliers, if present, are depicted as individual data points beyond the whiskers.

6. Outliers: Outliers are data points that significantly deviate from the rest of the dataset. In this case, there are no clear outliers based on the data provided.

7. Box: The box in the box plot spans from the lower quartile (Q1) to the upper quartile (Q3) and represents the middle 50% of the data. In this case, the box spans approximately from 23 to 35.

By observing the box plot, we can see that the data is moderately dispersed, with the majority of values concentrated around the median. The range of the data is approximately 20 to 38, with some variability within the dataset.

$\huge{\mathfrak{\colorbox{black}{\textcolor{lime}{I\:hope\:this\:helps\:!\:\:}}}}$

♥️ $\large{\underline{\textcolor{red}{\mathcal{SUMIT\:\:ROY\:\:(:\:\:}}}}$

To create a box plot for this data set, we need to find the minimum value, maximum value, median, and quartiles.

Minimum value: 18
First quartile (Q1): 22
Median: 29
Third quartile (Q3): 36
Maximum value: 38

The box plot is created using these values. A box is drawn from Q1 to Q3 with a line inside the box at the median. Whiskers are drawn from the box to the minimum and maximum values. Any data points beyond the whiskers are plotted as individual points.

In this box plot, the data is dispersed fairly evenly, with no outliers beyond the whiskers. The box is centered around the median, indicating that the data is roughly symmetric. The lower half of the data is slightly more spread out than the upper half, as indicated by the longer whisker on the left side of the box. Overall, the box plot shows that the data is relatively consistent, with no extreme values.

Which of the following sentences correctly uses parallel structure? In the scientific method, you propose a hypothesis, conduct an experiment, analyze the data, and you end with a reporting of your findings. The scientific method consists of proposing your hypothesis, conducting your experiment, analyzing your data, and reporting your findings. The scientific method begins with a hypothesis, continues with an experiment, then analyzing data, and reporting findings. To correctly follow the scientific method, you must hypothesize, experiment, analyze, and reporting your findings.

Answers

Answer & Step-by-step explanation:

The following sentence correctly uses parallel structure: "The scientific method consists of proposing your hypothesis, conducting your experiment, analyzing your data, and reporting your findings." In this sentence, all of the phrases are in the same form and describe actions that are part of the scientific method. Each phrase begins with a verb (proposing, conducting, analyzing, and reporting) and is followed by a noun that describes the action (hypothesis, experiment, data, and findings). This structure is parallel because each phrase has the same grammatical structure and describes a similar action.

The other sentences do not use parallel structure because they do not have the same grammatical structure or they do not describe similar actions. For example, in the first sentence, the phrases "propose a hypothesis" and "end with a reporting" are not parallel because they do not have the same grammatical structure. In the second sentence, the phrases "proposing your hypothesis" and "reporting your findings" are not parallel because they do not describe the same type of action (proposing is a mental process, while reporting is a physical action). In the third sentence, the phrases "begins with a hypothesis" and "reporting findings" are not parallel because they do not have the same grammatical structure (one begins with a verb and the other ends with a verb). Finally, in the fourth sentence, the phrases "hypothesize" and "reporting" are not parallel because they do not have the same grammatical structure (one is a verb and the other is a gerund).

Answer:

The scientific method begins with a hypothesis, continues with an experiment, then analyzing data, and reporting findings

Mark knew that the budget for the class day is $725.76. He claimed that 70% of the money will be spent on prizes and the booths.

Use reasoning to explain how Mark's claim is incorrect. What percent of the money will be spent on the prizes and the booths?

Answers

Mark is incorrect in a way.. With the 8% increase on $504 (504x1.08) That increases the new amount spent this year, to $544.32.

70% of $725.76 is only $508.03 (725.76x.3)

Step-by-step explanation:

By adding all the numbers you get 500, but you need to make it 100% so you divide the total number by five. To know what percent out of 100 you need to divide all of the variables by 5.

85 ÷ 5 = 172

40 ÷ 5 = 48

125 ÷ 5 = 25

50 ÷ 5 = 10

Thus the answer to your problem is, B. a circle graph titled social media usage, with four sections labeled vidtok 17 percent, headbook 48 percent, picturegram 25 percent, and tweeter 10 percent
