Final answer:
The mean of three numbers is 6 and the mode is 7. The lowest of the three numbers is 4.
Step-by-step explanation:
To find the lowest of the three numbers, we can use the fact that the mode is 7. This means that 7 appears most frequently among the three numbers. Since the mean is 6, the sum of the three numbers must be 6 * 3 = 18. Let's assume two of the numbers are 7, so the sum of these two numbers would be 14 (7 + 7 = 14). Therefore, the lowest number would be 18 - 14 = 4. So the lowest of the three numbers is 4.
