A hypothetical question, what is a hypothesis?

I don't think it's feasible. You want to ...The words you speak are in the generations and hundreds of generations.

This was followed by a few words. Even if these words can be passed on to future generations. If you can be found with a shuttle machine, will your descendants be able to tell you about your past?

Isn't it necessary for everyone to write an autobiography of their own life! And it has to be very detailed. Isn't that hard to do?

To be exact, it can't be done at all. How to change your fate. Big brother, I do admire your imagination.

no!No way!!

Suppose you said this, suppose there is really a time machine, then there must be a time machine that came to the present (because you said such a thing), but no one came, which means that future generations did not create a time machine! Or that there is no time machine!!

Leave. I don't want to. What is it? What does it mean for men? Be a principled person.

It's not just a matter of principle. What else to assume?

The man's indecisiveness made the woman so bold. Also, don't let that woman have a good time.

You go to borrow money before the divorce. Borrow a lot. (You transfer the money away, don't let the court know that your money is still there).Let the court know before leaving, and when the time comes, half of them will be returned. Torture her.

And also. Don't think about it. This is the only way.

Not leaving? Then this man is finished. There's only one thing to think about.

How to get revenge after leaving. Don't say anything: I've loved before with gibberish nonsense, think about how others treat your love.

It doesn't matter if the woman can't stand it for a while or what. The man still wants to wear a cuckold again?

If I could come back, the world would have been in turmoil.

Think about the countless people coming back, and the earth can't let go.

So I can't come back.

Have a good talk with her.

The problem is not just one person.

If you can't accept it, let's separate for a while.

You can't be impulsive now.

If you have children, you should deal with the problem calmly.

It's okay for two people to talk, and recognizing my sister doesn't mean anything, as long as the relationship is not ambiguous.

You've watched too many idol dramas, don't assume things that haven't happened yet.

You should be happy. Because you're not cold, you have a cuckold to wear.

No, I don't have time to think about other beauties, but my girlfriend is qualified enough

I'm very annoyed with this kind of boy, and the previous object is, I don't like it very much, I feel that he is very inattentive,

What does he mean by his sister?

Four, Four, Four, Four, Hypothesis, Hypothesis, Hypothesis, Hypothesis Engels once pointed out: "As long as natural science is thinking, its form of development is hypothesis."

Many influential scientific theories in the history of science, such as Mendeleev's periodic table and Copernicus's heliocentric theory, first appeared in the form of hypotheses. In solving mathematical problems, assuming that the unknown number is x, and listing equations to solve the problem, is based on the idea of hypothesis. Because of the assumptions, the unknown can be regarded as known, and complex quantitative relationships can be simplified.

The problem of "chickens and rabbits in the same cage" in ancient arithmetic in China was solved by the hypothetical method, which often assumed the existence of a certain phenomenon first, obtained a "difference" that was different from the known conditions, and then analyzed the cause of the "difference" and made appropriate exchanges to solve the problem. Example 1 There are 100 heads and 350 legs in the cage. (1990 Jinan Lixia District Primary School Mathematics Fifth Grade Competition Questions) Analysis:

Suppose 100 are all rabbits, then there should be 4 100=400 feet, 400-350=50 feet more than the actual one, if you replace a rabbit with a chicken, then you can reduce 4-2=2 feet, to reduce 50 feet 2=25 chickens, so you can find the number of chickens. Solution 1: (4 100-350) (4-2)=25 (head) chickens, 100-25=75 (heads) rabbits.

or (350-2 100) (4-2)=75 (head) rabbits, 100-75=25 (head) chickens. Solution 2: Set:

Chickens have x heads, then rabbits have (100-x) heads. 2x+4 (100-x)=350, the solution is x=25. 100-25 = 75 (head) rabbits.

A: There are 25 chickens and 75 rabbits.

In parametric hypothesis testing, the distribution type of the population is known, and the purpose of hypothesis testing is to test the population parameters, for which the researcher needs to put forward a hypothesis in advance in order to judge whether the hypothesis is true based on the sample statistics.

In parametric hypothesis testing, a "hypothesis" is a statement made about a specific value of a population parameter. In order for the sample statistic as evidence to necessarily support and support only one hypothesis, a pair of hypotheses that are logically complete and mutually exclusive for the population parameters should be established, i.e., the null hypothesis (denoted h0; Alternative hypothesis (denoted H1.

Hypothetical features

The null hypothesis and the alternative hypothesis are a pair of completely mutually exclusive events, and in one test, one of the null hypotheses and the alternative hypothesis is true.

Because the null hypothesis assumes that the population parameters have not changed, "=" is always on the null hypothesis, and although the null hypothesis may also have a direction, the actual test only needs to be done for the case when "=" is taken.

Since an alternative hypothesis is a hypothesis that the researcher hopes to support by collecting evidence to support the dilemma, in general, when establishing a hypothesis, the reserve hypothesis is established before determining the null hypothesis.

Since the hypothesis is based on the researcher's perspective and position, the same problem may have completely different directions or even reverse assumptions due to different positions.

Hypothesis is a Chinese word that refers to if; Conceived out of thin air; Scientists have put forward claims to explain the phenomenon but have not yet proven it. See "Hanshu Jia Yi Biography":"Suppose that His Majesty lives in Qi Huan's place, will it not be in line with the princes and the world? "

In Sinology, the basic interpretation of the hypothesis is:

Let's take it aside. Based on existing materials and experience, the reason for the occurrence of things and the laws of their development and change are speculated. Nearly assumed.

The explanation of the assumptions of objective things in scientific research, the assumptions are put forward on the basis of facts, and they become theories when they are proved to be correct by practice.

The detailed explanation is:

1.If, assum.

2.Invent. 3.Prepare for it;Borrow for the setup.

4.The explanation of the assumptions of objective things in scientific research should be put forward on the basis of facts, and become theories after being proved by experiments and tested in practice.

20x5=100 points.

100-76 = 24 points.

False: 24 (5+1) = 4 (Dao) potato rent.

Pair: 20-4=16 (channel).

20x5 = 100 points.

100-76 = 24 points.

False: Repentance 24 (Bilu 5+1) = 4 (Dao) True: 20-4 = 16 (Dao.

Question 1: Rabbit 18 Chicken 14

Column equation: rabbit x chicken y.

4x+2y=100

2x+4y=92

Then solve it.

The second question of the big monk is total: 1 25 = 25 (pieces) The third question of the little monk 75 is set to have x sheets of one corner and y sheets of 2 corners, then x+y=17 x+2y=25 is solved to obtain x=9, y=8

The small monks have a total of: 3 25 = 75 (pcs.

Question 4 can be understood like this:

If all 6 pits are dug, (6-4) 2 = 4 pits will be dug more.

If all 5 pits are dug, 3 fewer pits will be dug (5 pits per person, and 3 more pits will be dug).

Then the number of people digging (4+3) (6-1)=7 (people) can be found to be the number of tree pits is 5 7+3=38

The fifth question is set to 10 yuan with x sheets, then 2 yuan and 5 yuan have sheets, you can get:

10x＋〈2＋5〉×〈25－

x 10 A: 10 RMB 10 sheets.

Eldest brother.. It's not easy. Give it points.

From 7 o'clock to 12 o'clock, except for the top of the mountain to play for one hour, it is 4 small hours to tell Kai and time.

That is, up the mountain, down the mountain for a total of 4 hours, a total of 11 kilometers, as a chicken and rabbit cage.

Assuming that all the mountains are up, Sun Kong's 8 kilometers in 4 hours will be more than the upper mountain.

11-2 4) 3=1 (hour).

1 hour descent, 5 km;Go to the mountain for 3 hours and walk 6 kilometers.

Solution: Except for one hour of playing, a total of walking: 12-7-1=4h per hour when going down the mountain: 2+3=5km

Assuming that the whole process is a trembling meditation downhill speed walking, you need to walk 5 4 = 20 km more than the hole: 20-11 = 9 km

So walked up the hill: 9 3 = 3h

So walking up the hill: 2 3 = 6km

So walk downhill: 11-6 = 5km

Let's just assume that there are 100,000 copies of this book, and there is only one reader for each book, so there are 100,000 readers.

Fictional: The storyline is yes.

Hypothesis: The explanation of the assumptions of objective things in scientific research, the hypothesis should be put forward based on certain facts, and it is called a theory if it is proved to be correct in practice.

Hope that helps.
