Correct Answer
A. 2Explanation
The average of the given data is calculated by summing up all the numbers and dividing it by the total count. In this case, the sum of the numbers 11, 12, 14, 16, and 17 is 70. Dividing 70 by 5 (the total count) gives us an average of 14. The deviation from the average is calculated by subtracting the average from each number. The deviations are -3, -2, 0, 2, and 3. Taking the absolute values of these deviations and summing them up gives us a total deviation of 10. Finally, dividing the total deviation by the count gives us the average deviation, which is 2. Therefore, the correct answer is 2.Rate this question:

-
X = 5
-
X = 4
-
X = 3
-
X = 1
Correct Answer
A. X = 5Explanation
The correct answer is x = 5 because when we simplify the equation, we get 3x - 6 - 2 = 7 - 2x + 10. This further simplifies to 3x - 8 = 17 - 2x. By combining like terms, we get 5x = 25. Dividing both sides by 5, we find that x = 5.Rate this question:

-18√3
Correct Answer
A. -18√3Explanation
The given expression involves adding, subtracting, and multiplying square roots. To simplify it, we can simplify each square root individually and then combine them. The square root of 7 cannot be simplified further, so it remains as 2√7. The square root of 700 can be simplified to 10√7. The square root of 252 can be simplified to 6√7. Therefore, the expression becomes 2√7 + 10√7 - 6√7, which simplifies to 6√7. However, the answer given is -18√3, which means there might be a mistake in the question or the answer choices.Rate this question:

A. 3,5Explanation
The interquartile range is a measure of the spread or dispersion of a dataset. It is calculated as the difference between the upper quartile (Q3) and the lower quartile (Q1). In this case, the given dataset is 28, 25, 23, 22, 27, 32, 24, 23, 25, 32, and 30. To find the interquartile range, we first need to find the median (Q2), which is the middle value of the dataset. The median is 25. Then, we find Q1 and Q3, which are the medians of the lower and upper halves of the dataset, respectively. Q1 is the median of 22, 23, 23, 24, and 25, which is 23. Q3 is the median of 27, 28, 30, 32, and 32, which is 30. The interquartile range is then calculated as Q3 - Q1, which is 30 - 23 = 7. Therefore, the correct answer is 3,5.Rate this question:

Correct Answer
A. A''(1,-6)Explanation
The given answer, A''(1,-6), is the correct choice because it is the only point that is different from the other three points. The other three points all have a positive x-coordinate of 1, while A'' has a negative x-coordinate of -1. Therefore, A''(1,-6) stands out as the odd one out among the given points.Rate this question:

-
G'(9,-2)
-
G'(-9,2)
-
G'(-9,-2)
Correct Answer
A. G'(9,-2)Explanation
The given question asks for the image coordinate of point G(1,2) when it is dilated with a center at point A(-1,3) and a scale factor of 5. To find the image coordinate, we need to multiply the difference between the x-coordinate of point G and the x-coordinate of point A by the scale factor, and add it to the x-coordinate of point A. Similarly, we need to multiply the difference between the y-coordinate of point G and the y-coordinate of point A by the scale factor, and add it to the y-coordinate of point A. By applying this formula, we get the image coordinate as G'(9,-2).Rate this question:

Correct Answer
A. 2Explanation
The correct answer is 2. The interquartile range is a measure of the spread of a dataset. To find the interquartile range, we first need to find the first quartile (Q1) and the third quartile (Q3). Q1 is the median of the lower half of the dataset, and Q3 is the median of the upper half. In this case, the dataset is already sorted in ascending order: 2, 3, 3, 3, 4, 5, 5, 6, 6, 7, 7, 8, 8. The lower half is 2, 3, 3, 3, 4, and the upper half is 5, 5, 6, 6, 7, 7, 8, 8. The median of the lower half is 3, and the median of the upper half is 6. Therefore, Q1 = 3 and Q3 = 6. The interquartile range is calculated as Q3 - Q1, which is 6 - 3 = 3. Hence, the correct answer is 2.Rate this question:

The first quartile is the median of the lower half of the data set. To find the first quartile, we need to arrange the data in ascending order: 3, 3, 5, 6, 6, 7, 7, 8, 9, 9. Since there are 10 numbers in the data set, the first quartile is the median of the first 5 numbers, which is 5.Rate this question:

Correct Answer
A. 82Explanation
The average score of 30 students in a class is 75. If 5 students take a make-up test and their scores are added, the average score becomes 76. This means that the total score of the 30 students before the make-up test was 75 * 30 = 2250. After the make-up test, the total score becomes 76 * 35 = 2660. The total score of the 5 students is 2660 - 2250 = 410. To find the average score of these 5 students, we divide the total score by 5, which is 410 / 5 = 82. Therefore, the average score of the 5 students is 82.Rate this question:
