Answer:
56
Step-by-step explanation:
The mean is the average number of a data set.
To find the mean:
First, add all the numbers in the data set:
30 + 45 + 45 + 70 + 90 = 280
Next, divide the sum (280) by 5 (amount of values):
280 / 5 = 56
56 represents the mean of your data set.
1....2470, 2474
2....2471,2473,2477
3.....340, 341, 342, 343, 344
