To find the average number of goals scored per match, we need to calculate the total number of goals scored in all matches and divide it by the total number of matches.
Total goals scored = (0 * 4) + (1 * 10) + (2 * 5) + (3 * 9) + (4 * 7) + (5 * 5) + (6 * 1) + (7 * 2) = 0 + 10 + 10 + 27 + 28 + 25 + 6 + 14 = 120
Total number of matches = 4 + 10 + 5 + 9 + 7 + 5 + 1 + 2 = 43
Average number of goals scored per match = total goals scored / total matches = 120 / 43 ≈ 2.8
Therefore, the average number of goals scored per match is 2.8 goals.
The answer is B. 2.8.
