To find out how well elementary school students participate in physical activity after school, creat

Maybe for many people, we will have our own high school years, and at the same time, we will have our own good study and life, and sometimes I really feel very irritable, but in retrospect, that time is really beautiful and very happy. The Ministry of Education said that I didn't like sports activities for 30 minutes a day in primary and secondary schools, because I was not suitable for sports, and I also found it very annoying. <>

1. The Ministry of Education said that 30 minutes of recess sports activities in primary and secondary schools every day may be in our own lives, and we will all have our own life experiences, and sometimes we feel that being a student is really very carefree and very happy, and that time is really unforgettable.

When we saw that the Ministry of Education said that primary and secondary schools had 30 minutes of recess sports every day, for me, in the primary and secondary school period that I experienced, we would also have big recess activities at that time, but I didn't like big recess activities because I felt very hot, in the city where I lived, it was really super hot. <>

Second, for me, I didn't like big recess sports activities in middle school Maybe in our lives, we will all have our own way of life, and at the same time we will have our own attitude towards life, everyone has experienced the student period, maybe it is very beautiful, but for me, I also have things I don't like.

I remember that there was a big recess in our middle school at that time, and I really didn't like the big recess sports at that time, because it was too hot, and when we went out for sports activities, we came back sweating profusely, and there was no air conditioning in the classroom, and it would be very hot without a fan, so I didn't like it. <>

Maybe there will be things that you like when you are a student, and there will also be things that you don't like, but I didn't like big recess sports activities when I was in middle school, because it was too hot.

Like, especially basketball. Because basketball has the confrontation that belongs to men, it can also attract the twilight of female classmates.

I wasn't very fond of sports when I was in school. But I love PE class. Physical education classes are designed to enhance physical exercise and communication with classmates.

I like it very much, for example, when I play, I get a lot of joy when I play, and I feel that everything is so good, and I feel that my whole body is relaxed.

Solution: (1) 60 30% = 200 or 100 50% = 200 or 30 15% = 200, A: A total of 200 students were surveyed this time;

2) As shown in the figure below:

3) 1000 (1 50% 30% 15%) = 50, A: There may be 50 students in the whole school who spend less than an hour participating in physical activity per day on average (4) If there are 1500 students in the school, how many students in the school do you estimate to participate in physical activity for an average of more than one hour per day (as long as they can ask questions based on the information in the picture and answer the questions correctly).

<> solution: (1) 720 270

Frequency distribution map:

2) In 2010, there were about 8,000 middle school students in our school, and according to this transfer, it can be estimated that the number of middle school students in our school who practiced for more than l hours a day in 2010 was about 6,000;

3) In 2010, the number of students who exercised less than l hours was 6,000, and in 2011, the number of middle school students who exercised less than 1 hour per day dropped to 2,400, and the percentage of students who exercised less than l hours in 2011 was 6,0002400

2) The figure is shown below:

3) 1000 (1 50% 30% 15%) = 50, A: There may be 50 students in the whole school who participate in physical activities for an average of less than an hour per day

Unskinning bucket: (Peel 1) 60 30% = 200 or 100?0% = 200 or 30?÷5%=200

A: A total of 200 students were surveyed.

2) The figure is shown below:

3) 1000 (1 50% 30% 15%) = 50, A: There may be 50 students in the whole school who participate in physical activities for an average of less than an hour per day

3) 1000 (1 50% 30% 15%) = 50, A: There may be 50 students in the whole school who participate in physical activities for an average of less than an hour per day

4) If the school has 1,500 students, how many students in the school are likely to spend more than an hour a day in physical activity on average (as long as they can ask questions based on the information in the diagram and answer them correctly).
