Final answer:
The mean is 10.4, the mode is 12, and the median is 12.
Step-by-step explanation:
To find the mean, add up all the numbers in the set and divide by the total number of values. In this case, the sum is 104 and there are 10 values, so the mean is 10.4.
The mode is the value that appears most frequently in the set. In this case, the mode is 12 as it appears three times, more than any other value.
The median is the middle value of the set when it is arranged in order. In this case, the values in the set are already ordered. Since there are 10 values, the median is the average of the 5th and 6th values, which are both 12. Therefore, the median is also 12.
