What is the mean of the numbers 20, 7, 5, 8, 10?
Answer and explanation
Correct answer: D. 10
- Step 1: Add the numbers: 20 + 7 + 5 + 8 + 10 = 50. Step 2. Divide by 5: 50 / 5 = 10. Answer: 10. Why not the others: 8: That is the middle value after sorting, which is the median. 15: That is the range, the largest minus the smallest. 50: That is the total, which has not been divided by 5.
