Answer:
13
Step-by-step explanation:
\(39 \div 3 = 13\)
Answer:
k = 13
Step-by-step explanation:
k represents a number. You don't know what the number is.
3k = 39 means three times a number is 39. What is the number?
3k = 39
Divide both sides by 3.
k = 13
The number is 13.
Answer: k = 13

D: A number line with tick marks every one unit from negative 7 to 5. There is a closed circle at negative four and shading to the right that ends with an arrow pointing right at positive 1.
Answer:
C. A number line with tick marks every one unit from negative 9 to 1. There is a closed circle at negative four and shading to the left that ends with an arrow pointing left at negative 9.
Step-by-step explanation:
Step 1: Refine equation by multiplying both sides by 10
\(10(-0.7m + 5.6)\geq 8.4 *10\)
\(-7m+56\geq 84\)
Step 2: Subtract 56 from both sides
\(-7m\geq28\)
Step 3: Divide both sides by -7 (switch inequality sign)
\(m\leq-4\)

What is the appropriate measure of variability for the data shown, and what is its value?
The IQR is the best measure of variability, and it equals 32.
The range is the best measure of variability, and it equals 11.
The IQR is the best measure of variability, and it equals 11.
The range is the best measure of variability, and it equals 32.
To determine the appropriate measure of variability for the given data, we first need to determine the range of the data, which is the difference between the largest and smallest values. The largest value in the data set is 49, and the smallest value is 17. Therefore:
Range = Largest value - Smallest value = 49 - 17 = 32
The range tells us the spread of the entire data set, but it can be heavily influenced by outliers. To get a measure of variability that is resistant to outliers, we can use the interquartile range (IQR), which measures the spread of the middle 50% of the data. To calculate the IQR, we need to find the first quartile (Q1) and the third quartile (Q3) of the data.
From the stem-and-leaf plot, we can see that the smallest value is 17 and the largest value is 49. To find Q1 and Q3, we need to identify the median of the lower half of the data and the median of the upper half of the data, respectively. The stem-and-leaf plot shows:
1 7, 9
2 1, 5, 9
3 0, 1, 2
4 6, 9
The median of the entire data set is the value that splits the data into two equal halves. Since there are 20 values in the data set, the median is theaverage of the 10th and 11th values when the data is sorted in ascending order. The 10th and 11th values are both 24, so the median is 24.
To find Q1 and Q3, we need to split the data set into two halves at the median and find the medians of each half. The lower half of the data set consists of:
17, 19, 21, 23, 24, 24, 25, 26, 29, 29
The median of this half is (24 + 23) / 2 = 23.5, which is closer to 23 than to 24. Therefore, Q1 is 23.
The upper half of the data set consists of:
31, 32, 34, 35, 36, 39, 49
The median of this half is (35 + 36) / 2 = 35.5, which is closer to 36 than to 35. Therefore, Q3 is 36.
Now we can calculate the IQR as:
IQR = Q3 - Q1 = 36 - 23 = 13
Therefore, the appropriate measure of variability for the given data is the IQR, which equals 13.

please just make it simple i dont need an explanation i need a answer i can put into my school test
Sure, I can help you with that.
**Part A: Calculate the measures of center.**
The measures of center are the mean, median, and mode.
* **Mean:** The mean is calculated by adding all the values in the data set and dividing by the number of values. For the Sky View School data set, the mean is 5.8. For the South Lake School data set, the mean is 5.4.
* **Median:** The median is the middle value in the data set when the values are arranged in increasing order. For the Sky View School data set, the median is 6. For the South Lake School data set, the median is 5.5.
* **Mode:** The mode is the most frequent value in the data set. For the Sky View School data set, the mode is 5. For the South Lake School data set, the mode is 5.
**Part B: Calculate the measures of variability.**
The measures of variability are the range, standard deviation, and variance.
* **Range:** The range is the difference between the largest and smallest values in the data set. For the Sky View School data set, the range is 8. For the South Lake School data set, the range is 8.
* **Standard deviation:** The standard deviation is a measure of how spread out the data is. The larger the standard deviation, the more spread out the data is. For the Sky View School data set, the standard deviation is 1.7. For the South Lake School data set, the standard deviation is 1.5.
* **Variance:** The variance is the square of the standard deviation. For the Sky View School data set, the variance is 2.89. For the South Lake School data set, the variance is 2.25.
**Part C: If you are interested in a smaller class size, which school is a better choice for you? Explain your reasoning.**
If you are interested in a smaller class size, then the South Lake School is a better choice. The average class size at the South Lake School is 5.4, while the average class size at the Sky View School is 5.8. Additionally, the median class size at the South Lake School is 5.5, while the median class size at the Sky View School is 6. This means that half of the classes at the South Lake School have 5 or fewer students, while half of the classes at the Sky View School have 6 or more students.

PLEASE HELP ASAP !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Part A: To calculate the measures of center, we can find the median and the mean for each school.
For Bay Side School, the median class size is the average of the 8th and 9th values when the data is sorted in ascending order. The 8th and 9th values are both 25, so the median class size is 25.
To find the mean class size for Bay Side School, we can add up all the class sizes and divide by the total number of classes. The sum of the class sizes is 12 + 12 + 12 + 14 + 15 + 15 + 16 + 16 + 18 + 18 + 20 + 20 + 23 + 25 + 25 = 243. There are 15 classes, so the mean class size is 243/15 ≈ 16.2.
For Seaside School, the median class size is the average of the 8th and 9th values when the data is sorted in ascending order. The 8th and 9th values are both 15, so the median class size is 15.
To find the mean class size for Seaside School, we can add up all the class sizes and divide by the total number of classes. The sum of the class sizes is 10 + 10 + 10 + 11 + 12 + 15 + 15 + 16 + 17 + 17Part A (continued):
18 + 18 + 20 + 20 + 25 = 222. There are 14 classes, so the mean class size is 222/14 ≈ 15.9.
Therefore, the measures of center for Bay Side School are: median = 25, mean ≈ 16.2.
The measures of center for Seaside School are: median = 15, mean ≈ 15.9.
Part B: To calculate the measures of variability, we can find the range and the interquartile range (IQR) for each school.
For Bay Side School, the range is the difference between the largest and smallest class sizes. The largest class size is 25, and the smallest class size is 12, so the range is 25 - 12 = 13.
To find the IQR for Bay Side School, we need to find the first quartile (Q1) and the third quartile (Q3) of the data. From the stem-and-leaf plot, we can see that Q1 is 15 and Q3 is 20. Therefore, the IQR is 20 - 15 = 5.
For Seaside School, the range is the difference between the largest and smallest class sizes. The largest class size is 25, and the smallest class size is 10, so the range is 25 - 10 = 15.
To find the IQRPart B (continued): for Seaside School, we need to find the first quartile (Q1) and the third quartile (Q3) of the data. From the stem-and-leaf plot, we can see that Q1 is 12 and Q3 is 18. Therefore, the IQR is 18 - 12 = 6.
Therefore, the measures of variability for Bay Side School are: range = 13, IQR = 5.
The measures of variability for Seaside School are: range = 15, IQR = 6.
Part C: If you are interested in a smaller class size, Seaside School is a better choice because its measures of center are lower than those of Bay Side School, indicating that its class sizes tend to be smaller on average. Additionally, Seaside School has a smaller range and IQR, indicating less variability in class size. Therefore, there is less chance of encountering very large classes at Seaside School compared to Bay Side School.
