Final answer:
The best way to estimate Hazhair's score for each gymnastic event is to divide the rounded total points by the number of events, leading to the equation 35 ÷ 5 = 7.
Step-by-step explanation:
The student is asking how to estimate Hazhair’s score for each gymnastic event if the total score is 34.42 points for five events. To estimate the score for each event, we should divide the total score by the number of events. Rounding the total points to the nearest whole number gives us 34 points, which is closer to 35 than to 30 or 40. Therefore, the best estimate for each event would come from the equation:
35 ÷ 5 = 7
This equation suggests that if Hazhair scored a total of approximately 35 points across five events, then the average score per event would be about 7 points. This estimate is found by dividing the rounded total points by the number of events, which is option a.
