Answers
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
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.

Next, we know from looking at the formula that l and w are added together, so inside the brackets is an addition problem. ( + 28)
Since we know that l = x and l has to be doubled, it will be = (2x +)
If we combine those two equations together it is =

15. The product of two whole numbers is always a whole number. Verify this statement
with two examples.
Answers
The product of two whole numbers is always a whole number i.e. if 'a' and 'b' are any two whole numbers, their product will also be a whole number.
The multiplication of any two numbers can be expressed as the repeated addition of one number. So, for example, if we add a whole number to itself again and again, then we will definitely be left with the result of a whole number.
Let's assume
a = 2, b = 3.
a × b = 2 × 3 = 6
This is the same thing as adding '2' three times to itself, which will result in a whole number, which is 6 in this case.
Let's take another example 0 and 7. The product of these numbers is:
a = 0, b = 7
a × b = 0 × 7 = 0
As we know, 0 is also a whole number. Through these examples, we can understand that the product of two whole numbers is always a whole number.

Xenophon uses a reference to the Council of the Ephori that he does not further explain. Research and use reference works to identify the council and its purpose. Be sure to consider the point of view and evidence during your research.
Answers
Answer: Below
Step-by-step explanation: Xenophon, an ancient Greek historian, philosopher, and soldier, often referred to historical events and institutions without providing detailed explanations. In order to identify the Council of the Ephori and its purpose, we can consult reference works and consider the available evidence.
The Council of the Ephori, also known as the Ephors, was a prominent institution in the city-state of Sparta during the classical period of ancient Greece. They played a crucial role in the Spartan government and were responsible for various administrative, judicial, and executive functions.
The Ephorate was established as part of the Spartan governmental system, which was characterized by a mixed constitution that included elements of monarchy, oligarchy, and democracy. The Council of the Ephori was an integral part of the oligarchic aspect of the Spartan government.
The primary purpose of the Council of the Ephori was to act as a check on the power of the two Spartan kings. Sparta had two hereditary kings who shared the executive authority, but the Ephors were elected annually and had the power to oversee and regulate the kings' actions. They had the authority to monitor the kings' conduct, judge their adherence to Spartan laws and customs, and even depose them if necessary.
Additionally, the Ephors had significant administrative responsibilities. They supervised the education of Spartan youth, oversaw the training of the military, and managed various public affairs. They were involved in the collection and distribution of state revenue, the implementation of laws, and the administration of justice.
The Council of the Ephori consisted of five members, who were elected by the Spartan citizens. The selection process involved a combination of election and lot-drawing, ensuring a degree of democratic participation. The Ephors held considerable power and influence within the Spartan society, and their role as a check on the kings helped maintain the stability and balance of power in the Spartan government.
In Xenophon's writings, he often mentioned the Council of the Ephori in the context of Spartan political affairs and decision-making. While he assumed his readers were familiar with the institution, he rarely provided explicit explanations. This approach was common in ancient Greek historical works, as they were often written for an audience that already possessed a certain level of knowledge about Greek institutions and customs.
To better understand the Council of the Ephori and its significance, one can consult ancient Greek historians like Herodotus, Thucydides, and Plutarch, who provide more detailed accounts of Spartan political institutions and the role of the Ephors within them.

90° counterclockwise rotation
270° clockwise rotation
90° clockwise rotation
180° counterclockwise rotation
Answers
Answer: 90° clockwise rotation
Step-by-step explanation:
The rules for rotation are below:
90° clockwise rotation = (x, y)→(y, -x)
270° clockwise rotation = (x, y)→(-y, x)
180° counterclockwise rotation = (x, y)→(-x, -y)
90° counterclockwise rotation = (x, y)→(-y, x)
Let's take point B. Point B's coordinates are (3, -2). Point B' is (-2,-3). -x would be -3, and y stays the same.
Therefore, the answer is 90° clockwise rotation.

Perimeter: 380ft
Answer:
The perimeter is 380 ft^2.
Step-by-step explanation:
To find the perimeter of a rectangle, you have to use the 2(a+b) formula as a method of solving. This formula can also be written as a+b+a+b or 2a+2b.
To solve it, you input a as 51 and 139 as b, though this doesn't really matter all too much. Using the previously stated formula, you should get 2(51+139). Solving what's in the parenthesis first (51+139), you should get 190.
Now, you should have the answer 2(190). Finishing off the equation and multiplying 2 by 190, your answer will be 380 ft^2.

Step-by-step explanation:
MEAN can be find bg the sum of all score divided by the amount of the score.
Mean = total amount / number of amount
Total amount = 2 + 3 + 5 + 9 + 17+ 22 + 31 + 39
= 128
number of amount = 2, 3, 5, 9, 17, 22, 31, 39
= 8
Then we can calculate mean as
Mean = 128/8
Mean = 16
2+3+5+9+17+22+31+39=128

So basically the units are counting up by 5.
The x axis is age in years and y axis is the number of US states named in 60 seconds.
Since you didn’t give me the data to make the other 5 points, I can’t really answer the last question, but from the graph that I did make, there are no points that would be considered outliers, and there are no clusters in sight.
(BTW THIS IS IMPORTANT!! - when you use the data to add the other 5 points, there might be an outlier or more then one outlier. And there might be a cluster. Just look at it after you graph the last 5 and change the answer I gave you if there is an outlier or cluster)
