I cant understand your question, please make it more clear

what is your question then?

Three statisticians went out hunting, and came across a large deer. The first statistician fired, but missed, by a meter to the left. The second statistician fired, but also missed, by a meter to the right. The third statistician didn't fire, but shouted in triumph, "we got it!"
 

A statistics major was completely hung over the day of his final exam. It was a True/False test, so he decided to flip a coin for the answers. The stats professor watched the student the entire two hours as he was flipping the coin...writing the answer...flipping the coin...writing the answer. At the end of the two hours, everyone else had left the final except for the one student. The professor walks up to his desk and interrupts the student, saying:
"Listen, I have seen that you did not study for this statistics test, you didn't even open the exam. If you are just flipping a coin for your answer, what is taking you so long?"

The student replies bitterly, as he is still flipping the coin: "Shhh! I am checking my answers!"

Atleast there is a reliable source in this site then :D

You dont even seem to try and you are pretty much spamming the questions list but ill help you:

S_m=(a+(a+d*(m-1)))*m/2

S_n=(a+(a+d*(n-1)))*n/2

S_m/S_n=(m/n)*(2a+d(m-1))/(2a+d(n-1))=m²/n²

Therefore, (2a+d(m-1))/(2a+d(n-1))=m/n

What you need to do is to show m=n or 2a=d, then ill show you the answer.

Atleast try to do something

Yes there is a point... its fine to not understand it on the first try. And im sure you understood the question itself. English is not my first language and i understood what the meaning of the question is.

Besides, theres no point at asking for the solution of a question of the form "prove that if ___ then ___" because there is only one final answer. If you got a solution then all you need to do is check the way you got there is legit, not compare with other people.

The point of such questions is to get the information you know to a simple form, helping you to a simple form.

Ill give you a hint: you can prove that d=2a OR n=m. Both of these can lead you to the answer you need.

OR a relationship between n and m. There are 2 options, both lead to the wanted answer.

First member of the A.P- a

a_n-a_n-1=constant=d

You shouldnt have a problem if you know how to sum an A.P

Im starting to think you post every math problem you have HERE without even solving it.

Im not really into science but what is the data?

To catch them is my real test, to train them is my cause

I will travel across the land, searching far and wide,

Each pokemon to understand, the power thats inside.
