Final answer:
No, the mean of six numbers being 48 does not mean that one of the numbers has to be 48. The individual numbers can vary as long as their sum is 288.
Step-by-step explanation:
No, when the mean of six numbers is 48, it does not necessarily mean that one of the numbers has to be 48. The mean is calculated by adding all the numbers together and dividing by the total number of numbers. So if the mean is 48, it just means that the sum of the six numbers is 48 multiplied by 6, which is 288. The individual numbers can vary as long as their sum is 288. For example, the six numbers could be 50, 46, 40, 38, 60, and 54, which add up to a total of 288.
