is his mean daily expense? ​

Answer 1

Answer:

The mean expense is approximately equal to 53.714

Step-by-step explanation:

When you are trying to find the mean of a number set, you are trying to find the average of the stats. As such, use the formula Sum of the Numbers / Total Number of Values.

In this case, we are adding 54 + 61 + 42 + 63 + 42 + 56 + 58, which is equal to 376. We are then dividing this by 7, which is equal to about 53.714.
