Answer
The mean is 40.6.
Solution
To find the mean, add all the numbers and then divide by the total count.
Numbers: 56, 42, 37, 29, 45, 51, 30, 25, 34, 57
Step 1: Sum the numbers:
56 + 42 = 98
98 + 37 = 135
135 + 29 = 164
164 + 45 = 209
209 + 51 = 260
260 + 30 = 290
290 + 25 = 315
315 + 34 = 349
349 + 57 = 406
Step 2: Divide the sum by the number of data values (10):
406 / 10 = 40.6
Thus, the mean is 40.6.

Simplify this solution Bonus Knowledge
To find the mean, add all the numbers together and then divide by the total count of the numbers. Adding up: \( 56 + 42 + 37 + 29 + 45 + 51 + 30 + 25 + 34 + 57 = 405 \). There are 10 numbers in total, so divide 405 by 10. Mean = \( \frac{405}{10} = 40.5 \). It seems that none of the provided options match the calculated mean of 40.5. Let's check those options again for accuracy.
