I cleared the real-life game

Chapter 349 I will never drink yogurt again in my life

There is a saying that has been circulating in high school mathematics exams.

——Mathematics is required for those who have to choose to fill in the form.

The general idea is that if you want to get high scores in mathematics, you have to maintain the accuracy of multiple-choice questions and fill-in-the-blank questions.

After all, each optional question is worth 5 points. If you make one or two mistakes, it's fine. But if you make three or four mistakes, it will start to hurt.

Although the major questions account for a high score, in fact the scores that everyone can get are not very different, so naturally it is difficult to widen the gap with teammates.

Therefore, there is such a saying.

So after finishing the first sixteen questions, Lin Jiqiu felt that even if he didn't get a 100% success in the math test this time, he would at least be average.

As a result, the first big question left him a little confused.

Generally speaking, question 17 is either a sequence reasoning or a trigonometric function operation.

But no matter which one it is, it is basically the simplest and most basic question type. Like the first five or six multiple-choice questions, it is like a free-point question.

But this time, the old man who asked the question obviously didn't play his cards according to the routine.

Although the test points are indeed the sine and cosine theorems and the tangent formula that must be tested, the calculation process is obviously much more complicated.

Especially the second question that requires solving the triangle ABD actually requires a series of complex operations, coupled with the knowledge of similar triangles, to solve it.

This made Lin Jiqiu couldn't help but start to wonder if she had used the wrong method, leading to a detour.

All in all, after the first big question started, Lin Jiqiu felt that she smelled something not so wonderful.

And when Lin Jiqiu turned to the next page with a rather uneasy feeling——

Murphy's Law was so ruthlessly fulfilled in front of him.

Once again, according to common sense, this position of question 18 should be a question that is not too difficult, and it is a question about calculating probability or mathematical expectation.

Sometimes, this type of questions is even simpler than the previous 17 questions.

But obviously - there must be some big problem with this year's question.

Because the first thing that caught Lin Jiqiu's eyes was a large piece of text.

It almost takes up half a page of the test paper.

Lin Jiqiu's heart skipped a beat, and her gluteal muscles trembled instantly.

Leaving aside the difficulty of this question, the visual impact brought by the length of this question is already huge enough.

With a hint of admiration and a bit of trembling, Lin Jiqiu slowly lowered her gaze and began to read the question.

"A supermarket plans to order a type of yogurt on a monthly basis, with the same purchase volume every day. The purchase cost is 4 yuan per bottle, and the selling price is 6 yuan per bottle. The unsold yogurt will be processed at a reduced price, and all will be processed on the same day at a price of 2 yuan per bottle... …”

"According to usual experience, the sales volume of yogurt is closely related to the temperature."

"If the maximum temperature is not less than 25, the demand is 500 bottles; if the maximum temperature is in the range [20, 25), the demand is 300 bottles; if the maximum temperature is below 20, the demand is 200 bottles..."

"In order to formulate the best sales strategy, the company collected the highest temperature data for each day in June in the past three years and obtained the following frequency distribution table..."

Next to it is a fancy statistics table.

In short, after Lin Jiqiu finished reading the entire question, she only remembered one word in her mind——

Yogurt.

To be honest, Lin Jiqiu used to be considered a half-yoghurt enthusiast. Occasionally, she would buy some old yogurt or flavored fermented milk to satisfy her cravings in the small supermarket on campus.

So I spend so much money on you, and you treat me like this, right? Dog yogurt!

Continuing to look down, the things that need to be calculated in the question are quite conventional, just distribution columns and mathematical expectations.

But after a little analysis, Lin Jiqiu discovered that the situation was not as simple as imagined.

The distribution column of the first question is pretty good and not too difficult.

But the second key question is a bit complicated.

First of all, there are several intervals for the value of n alone, and the situation in each interval must be calculated separately.

The temperature is another independent variable. Under this variable, the value of Y must also change.

If we follow the process and calculate it honestly, I am afraid that the process of answering this question will require writing a short essay. "No wonder the answer area for this question on the answer sheet is so large..." The corners of Lin Jiqiu's mouth twitched involuntarily.

So after a brief half-minute of thinking, Lin Jiqiu made a somewhat difficult decision.

——Skip this question first.

If this kind of thing were told to others in ordinary times, it would most likely be called "outrageous".

Because this is only question 18...

Generally speaking, on a mathematics college entrance examination paper, the truly challenging problems will only appear in the last two questions.

And it’s usually the last little question.

As a result, the second big question has been skipped now. Is this a stupid test?
While flipping the papers, Lin Jiqiu quickly looked at the other students around him.

Only then did I realize that in fact, most of the students had text signs like [nervous], [confused], or even [fearful] on their heads, symbolizing negative states.

And this is quite abnormal.

After all, to be fair, Lin Jiqiu had taken every exam, large and small, in the past three years.

This was the first time he had seen an exam like this that had a bit of a mournful look from the very beginning.

Even if it is the Chinese language test in the morning, it will not be exaggerated to this extent.

It is enough to show that this mathematics test is indeed a bit unusual.

After skipping question 18, the next question is naturally the calculation question of solid geometry.

For this type of questions, the test points and solutions are generally relatively fixed.

There is little talk about what innovative topics will appear here.

But Lin Jiqiu just felt that it was not easy to write no matter how she wrote it.

The numerical values ​​are quite complex, and the amount of calculation of the normal vector is not small at all.

The most annoying thing is that the second question asks for the calculation result of the cosine of a dihedral angle!

Compared with the usual questions that just calculate the length of a certain side or the angle of an ordinary angle, the difficulty is not at the same level at all.

This forced Lin Jiqiu to even activate the [Quick Calculation] specialization to calculate a lot of complicated formulas with various trigonometric symbols and radicals.

[Quick Calculation] This ability is his trump card, and it consumes a huge amount of [Mental Power].

So before the exam started, Lin Jiqiu had already made a plan to use this card on the final analytical geometry and derivative questions.

But obviously the plan has changed now, and he has no choice but to come up with his plan B.

then.

With the blessing of the [Speed ​​Calculation] specialization, Lin Jiqiu successfully completed the calculation problem of solid geometry without any danger.

After that, taking advantage of the clear brain circuit in the [Quick Calculation] state, Lin Jiqiu quickly turned around and wrote the previous yogurt question.

Then, I wrote the polar coordinates of the selected topic as quickly as possible.

As expected, even with the power of [Quick Calculation], it still took a lot of time.

"You have to hurry up..."

Lin Jiqiu's forehead was sweating a little.

now.

There are only the last ten minutes left before handing in the paper.

But now, he still hasn't written the last two big questions.

conic sections, and reciprocals.

——All heavyweight questions.
