However, Ye Qianqian seemed to have encountered a difficult problem that even she was troubled by.
After discussing with the top student for a long time, he couldn't come to a conclusion.
"Hmm…this solution is too complicated. It takes a long time to calculate in the examination hall. There must be a simpler solution. Let's put this question aside for now.”
Ye Qianqian frowned and took a photo of the question with her phone. She planned to go back and study it carefully.
"Actually, you can try using Chebyshev's Inequality.”
Chu Feng's lazy voice came from behind.
Ye Qianqian was stunned.
Chebyshev Inequality?
Isn't that the formula for calculating the deviation and the deviation of random variables?
What did it have to do with this question?
Wait a minute.
Deviation…
Data distribution!
That's right!
This question could also be calculated using probability theory?!!
However, the questions were too tempting.
He had limited his thinking to linear algebra.
This train of thought was really wonderful!
Which student thought of it?
She turned around in surprise.
However…this face was a little unfamiliar to her.
He was indeed a student in his class, but he was not very familiar with him.
He didn't seem to be among the top students in mathematics, right?
Ye Qianqian was very puzzled.
"This student, you…what's your name again?”
"Chu Feng, the wind of the storm."
Chu Feng raised his head and smiled.
"Ah, so it's Chu Feng. I forgot your name for a moment.”
Chu Feng maintained his smile and didn't expose her.
"Just now, you said that you could solve this problem with Chebyshev's Inequality. I thought about it and it's indeed a good idea. Have you done this kind of problem before?”
"No, I saw you guys chatting just now and took a glance.”
Chu Feng said casually.
Ye Qianqian pouted. The horn twitched.
She had always been very confident in her mathematics skills.
But even so, she was still tempted by the question.
You came up with the right idea with just a glance?
Were all the students nowadays so amazing?
She decided to go back and check Chu Feng's past results.
He was so good at mathematics, how could he not have any impression of him?
……
Mathematics class ended.
The last period was physical education.
This class was the annual physical education standard test.
It was also a chance for the sports enthusiasts in the class to show off.
Chu Feng's class 'physical education teacher was a young female teacher who had just graduated this year and was here for an internship.
Her name was Xia Lan.
Her appearance and figure were very eye-catching.
He would wear sportswear every time he went to class.
It was neither loose nor tight, but it showed off her figure perfectly.
As a physical education teacher, Xia Lan wasn't hot-tempered. Instead, she was able to get along well with her students.
Therefore, the weekly physical education class was the favorite class of many people.
"Alright, students, everyone should know that we are going to have a sports test today. The first event is to test your lung capacity. Everyone, line up according to your student number.”
On the field, Xia Lan said to the students who were standing in two rows.
Testing lung capacity.
It was to use a blowing mouth that looked like a funnel and connect it to an instrument.
Then, he blew air into it.
One breath.
The more he bragged, the better.
For normal boys, the number they would usually brag about was around two to three thousand.
Some with good lung capacity could blow four to five thousand.
Last year, there was a god in Chu Feng's class who boasted 6600 yuan in one breath.
It was simply terrifying.
There were relatively fewer girls.
Chu Feng's score last year was 3,200.
It was a standard result.
But today.
He decided to give it a try and see how much his lung capacity could reach after the system's modification.
The teacher called out names one by one and blew on them.
The girl who was selected first.
The results of the girls were generally not high.
The highest number was 3,500.
But when it came to boys.
It started to explode. There was a burst of exclamations.
Three thousand five hundred.
4,800.
5,200.
It was as if they were competing with each other.
Each one boasted more than the last.
After blowing, their faces were flushed red and they could not breathe for a long time.
He was the God who had boasted 6600 last year.
The results were refreshed again.
It was a total of 7,100.
Even the PE teacher was shocked.
For those who had not undergone intensive training.
To be able to boast such a value, it could be said that it was very different. How ridiculous!
One had to know. Even our country's famous swimmer, Sun Yang, only had a lung capacity of over 7,000!
And in America's swimming world, there was a legendary figure called Phelps.
It was said that his lung capacity had exceeded 10,000.
It reached a terrifying 15,000.
This was also the maximum lung capacity known to humans!
