19. The mean of the data set is 18. What number is missing?
21, 11, _, 27, 22, 13, 16
20. The median of the data set is 81. What number is missing?
82, 87, _, 77, 70, 80, 88
14. The missing number would be 21, which makes the 21 the mode.
19. The missing number of the data set with a mean of 18 is: 16.
20. The missing number would be 81, which is the median.
The mode is the data point that appears the most in a data set.
The median is the middle value or average of the middles values in a an ordered data set.
The mean is the average value of the data set.
14. The missing number would be 21, which makes the 21 the mode.
19. Mean = (21 + 11 + x + 27 + 22 + 13 + 16)/7 = 18
110 + x/7 = 18
110 + x = (18)(7)
110 + x = 126
x = 126 - 110
x = 16
Therefore, the missing number of the data set with a mean of 18 is: 16.
20. Let the missing number be x, then order the data set:
70, 77, 80, x, 82, 87, 88
The missing number would be 81, which is the median.
