they didnt repeat they were checking their answers to all of their questions!
To find the mean, median, and mode of a set of numbers, you can follow these steps:
1) Mean: To find the mean, add up all the numbers in the set and then divide the sum by the total number of values.
2) Median: To find the median, first arrange the numbers in ascending order. If the total number of values is odd, the median is the middle number. If the total number of values is even, the median is the average of the two middle numbers.
3) Mode: The mode is the value(s) that appears most frequently in the set. If there is no value that appears more than once, then there is no mode.
Now let's check your answers:
1) Mean: To find the mean of the set (8, 12, 6, 9, 5), add up all the numbers: 8 + 12 + 6 + 9 + 5 = 40. Then divide the sum by the total number of values, which is 5. Therefore, the mean is 40/5 = 8. Your answer is correct.
Median: To find the median, arrange the numbers in ascending order: 5, 6, 8, 9, 12. The total number of values is odd, so the median is the middle number, which is 8. Your answer is correct.
Mode: Since no number appears more than once, there is no mode. Your answer is correct.
2) Mean: To find the mean of the set (3.4, 0.53, 1.3, 2.9, 1.47, 0.24), add up all the numbers: 3.4 + 0.53 + 1.3 + 2.9 + 1.47 + 0.24 = 9.94. Then divide the sum by the total number of values, which is 6. Therefore, the mean is 9.94/6 ≈ 1.64. Your answer is correct.
Median: To find the median, arrange the numbers in ascending order: 0.24, 0.53, 1.3, 1.47, 2.9, 3.4. The total number of values is even, so the median is the average of the two middle numbers, which are 1.3 and 1.47. Therefore, the median is (1.3 + 1.47)/2 ≈ 1.385. Your answer is correct.
Mode: Since no number appears more than once, there is no mode. Your answer is correct.
3) Mean: To find the mean of the set (-6, 3, -2, 6, 7, -3, -5, 8), add up all the numbers: -6 + 3 + (-2) + 6 + 7 + (-3) + (-5) + 8 = 8. Then divide the sum by the total number of values, which is 8. Therefore, the mean is 8/8 = 1. Your answer is incorrect.
Median: To find the median, arrange the numbers in ascending order: -6, -5, -3, -2, 3, 6, 7, 8. The total number of values is even, so the median is the average of the two middle numbers, which are -2 and 3. Therefore, the median is (-2 + 3)/2 = 0.5. Your answer is incorrect.
Mode: Since no number appears more than once, there is no mode. Your answer is correct.
4) Mean: To find the mean of the set (-17, 32, -9, 0, 52, 12, -14), add up all the numbers: -17 + 32 + (-9) + 0 + 52 + 12 + (-14) = 56. Then divide the sum by the total number of values, which is 7. Therefore, the mean is 56/7 = 8. Your answer is correct.
Median: To find the median, arrange the numbers in ascending order: -17, -14, -9, 0, 12, 32, 52. The total number of values is odd, so the median is the middle number, which is 0. Your answer is correct.
Mode: Since no number appears more than once, there is no mode. Your answer is correct.
