46

Answer 2

46

Explanation:

So, we have these values:

40: 1 time

41: 2 times

45: 1 time

48: 2 times

49: 3 times

50: 1 time

A total of 10 dots spread over 6 values.

We need to calculate a weighted mean (average) for them... so, we add up each dot then divide the total by 10:

40 + 41 + 41 + 45 + 48 + 48 + 49 + 49 + 49 + 50 = 460

460 / 10 = 46
