Answer 1

Answer:

42.3

Step-by-step explanation:

The mean is the average. To find the average, you add up all the numbers (310), divide them by the amount of numbers that there are (7), and that's it! So 310 divided by 7 is ‭44.285714285714... But what you need is a number rounded to the tenth, so we forget about all the numbers except for the whole numbers and the first two numbers after the decimal point: 44.28. 8 is larger than 4, so the 2 is going to be rounded up: 44.3
