(1) The scores of most candidates are below 50 (test paper 120), the proportion below 30 is close to one third, and the proportion below 50 is 80%. Generally speaking, most science students in senior high schools are good at mathematics learning, and the achievement level of candidates in Anhui Province was at the forefront of the country at that time. In other words, in the forefront of the provinces, science candidates have so many math scores. It is conceivable that in other provinces, how good the results can be!
(2) Taking the top four topics considered by the Mathematics Proposition Group of the College Entrance Examination as an example, the results are also poor. Regarding the first question, 750 test papers were randomly selected, among which 25 of the 5 small questions were correctly answered, accounting for 3.3%, and 196 scored 0, accounting for 26. 1%. On the second big question, 180, 2 people answered 6 small questions correctly, accounting for 1. 1%, and 17 people got 0 points, accounting for 9.4%.
(3) Unsurprisingly, the finale of college entrance examination science mathematics is another topic involving recursive sequence. The intention of proposition is basically the same as in previous years, and it is still the basic knowledge of examining sequence, the proof of inequality and the application of mathematical induction. However, this problem involves a nonlinear recursive sequence, which is quite difficult. At the same time, this problem also involves the background of many sequence limits, so it is even more difficult!
