Final answer:
The three numbers which have a mode of 7, a median of 7, and a mean of 8 are 7, 7, and 10. We can find this out using the statistics formula of mean, median and mode.
Step-by-step explanation:
To find three numbers that have a mean of 8, a median of 7, and a mode of 7, you will need to understand these three terms. The mean is the average of all numbers in a data set, calculated by adding all the numbers and dividing by the amount of numbers. The median is the middle number in a sorted list of numbers. The mode is the number that appears most frequently in a data set.
In this case, since we need three numbers, two of them could be 7 (which makes it the mode and the median), and the last number needs to be selected such that the mean of these three numbers is 8. That third number would be 10 because (7+7+10)/3 equals 8.
Thus, the three numbers are 7, 7, and 10.
