Answers
Out of the 150 people surveyed, 27 of them prefer mustard on a hot dog.
To estimate how many people out of the total 5,000 attendees prefer mustard, we can use proportions. We know that 27 out of 150 people prefer mustard, which is 18% of the sample. If we assume that the proportion of people who prefer mustard is the same in the entire population of 5,000 attendees, then we can estimate that:
0.18 x 5,000 = 900 people prefer mustard on a hot dog.
Therefore, based on the given data, an estimated 900 people in attendance would prefer mustard on a hot dog.

Step-by-step explanation:
those three answers add up to 2x+5
Answer:
Option (A), (D), (F)
Step-by-step explanation:
Option (A) = 2x + 5
Option (D) = 4x + 11 - 2x - 6
Option (F) = 2x - x + 3 + x - 3 + 5
Now let’s Prove this statement.
(A) = 2x + 5
= 2x + 5
(D) = 4x + 11 - 2x - 6
= 4x - 2x + 11 - 6
= 2x + 5
(F) = 2x - x + 3 + x - 3 + 5
= 2x - x + x + 3 - 3 + 5
= x + x + 5
= 2x + 5
As we can see that all the 3 equations give the same result as 2x + 5
Hence we can prove that Option (A), (D), (F) are all equal.

Thus,
Total population of any area million square kilometer people per square kilometer
miilion
Brazils area = 3 x 10^6 = 3000000 square miles
Japans area = 2 x 10^5 = 200000 square miles
Now we can divide Brazils area by Japans area, to find out how many times bigger Brazil is than Japan:
3000000 / 20000 = 15

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.
Answers
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.

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

Answers
To determine which bus typically has the faster travel time, we need to compare the measures of center for each data set. Since the data sets are relatively small and do not appear to have any extreme outliers, we can use either the mean or median as the measure of center.
Looking at the two line plots, we can see that Bus 18 has more dots clustered around the lower end of the scale, while Bus 47 has more dots spread out across the entire range of values. This suggests that Bus 18 may have a faster typical travel time.
Calculating the median for each data set confirms this suspicion. For Bus 18, the median is 13, which means that half of the students have a travel time of 13 minutes or less, and half have a travel time of 13 minutes or more. For Bus 47, the median is 16, which means that half of the students have a travel time of 16 minutes or less, and half have a travel time of 16 minutes or more.
Therefore, we can conclude that Bus 18 typically has the faster travel time, with a median of 13 minutes.

Answers
Answer:
The Range Stays 48°.
Step-by-step explanation:\
Since the value 80.4° is not the highest and not the lowest value on the list, it does not change the range.
Hope this helps!
Answer: B. The range stays 48
Step-by-step explanation:
The largest answer is 105 and the smallest answer is 57. The range is the range of numbers from smallest to largest so to find the range you subtract the largest and the smallest
Range = 105 - 57
Range = 48
The range will not change because if you put 80.4 in there, it's not the largest or smallest so it does not affect the range.
So answer is B. The range stays 48

The median is the best measure of center because there are outliers present.
Answers
The median is the best measure of center because there are outliers present.
In this graph, there are some values that occur more frequently than others, which means that the data is not evenly distributed. Additionally, there are some values that are much larger than the others, such as the three dots above 3 and the single dot above 9. These values are considered outliers because they are much larger than the other values in the data set. Outliers can significantly affect the mean, making it an unreliable measure of center. Therefore, the median is a better measure of center for this data set because it is not affected by outliers.

Bc.
Answers
To solve for w, you need to isolate the variable on one side of the equation.
The equation is 3/4 w = 6.
To isolate w, you need to divide both sides of the equation by 3/4.
3/4 w / 3/4 = 6 / 3/4
The left side simplifies to w, because the 3/4 on the left side cancel out.
w = 6 / 3/4
To divide by a fraction, you need to multiply by its reciprocal.
w = 6 * 4/3
The right side simplifies to 8.
w = 8
Therefore, w = 8.

Line segment AB is bisected at point G by ray XY. Which of the following is true about point G?
Answers
When a line segment is bisected, it means that it is divided into two equal parts. In this case, line segment AB is bisected at point G by ray XY. Therefore, point G is the midpoint of line segment AB. This means that point G is equidistant from both endpoints of the line segment, and that it divides the line segment into two equal parts. So, the correct statement about point G is that it is the midpoint of line segment AB.
Line segment AB is bisected at point G by XY. Hence (option C), G is the midpoint of AB.
A line segment is a part of a line. It has an ending and starting point. Examples of line segments are the edges of a table, the side of a square or a rectangle.
A line bisector cuts the line segment into equal half. It intersects the other line segment at the mid-point.

What is Probability?Probability is a measure of the likelihood of an event occurring and is expressed as a number between 0 and 1, inclusive. An event with a probability of 0 is impossible, while an event with a probability of 1 is certain.
Probabilities can be expressed as fractions, decimals, or percentages. To convert a decimal or a percentage to a fraction, we write the decimal or percentage as a fraction with a denominator of 1 and simplify the fraction if possible.
For example, if the probability of an event is given as 0.75, we can write this as 75/100. We can simplify this fraction by dividing both the numerator and denominator by 25 to obtain 3/4. Therefore, the probability of the event can be expressed as the fraction 3/4.
Similarly, if the probability of an event is given as 60%, we can write this as 60/100. We can simplify this fraction by dividing both the numerator and denominator by 20 to obtain 3/5. Therefore, the probability of the event can be expressed as the fraction 3/5.
Probabilities can be used to make predictions about the likelihood of future events, and they are an important tool in many fields, including statistics, science, and finance.

To design a spinner with the given probabilities, we can use the following sectors:
A sector covering 60 degrees for the number 1, with probability 1/6.
A sector covering 120 degrees for the number 3, with probability 1/3.
A sector covering 180 degrees for the number 7, with probability 1/2.
A sector covering 180 degrees for the odd numbers (1 and 3), with probability 1.
To create the spinner, draw a circle and divide it into four equal sectors. Color one sector red for the number 1, color two adjacent sectors green for the number 3, color one remaining sector blue for the number 7. Finally, color half of the blue sector green to represent the odd numbers.
The resulting spinner will have the desired probabilities: P(1) = 1/6, P(3) = 1/3, P(7) = 1/2, P(odd number) = 1.
