An apartment without a number on it? No way. The answer is 49.

@bobbym:

3) How did you get those 2 answers.The EF algorithms you gave me won't do 1 / 2.

Hello;

I'm not a member and I upload there all the time.

How about how I used the probability command with a conditional in the latter?

#5 Re: Exercises » Mathematics Challenges, #1 » 2016-07-17 00:36:39

So what is it for 3? With replacement or not?

When you're in doubt do both.

bobbym, what do you think of the second answer?

You aren't going to finish with that awful Colonel story?

#8 Re: Computer Math » Polynomial Root Finding » 2016-06-19 04:05:25

Feels good to have everything ready cause you've already did it?

The front end in Mma is confusing. He needs to learn its capabilities.

He should change his screen precision. Six digits are for children.

Shift - Enter line 3 again and again.

In an iterative root finding process, we start with some seed value and try to improve upon that answer with each iteration, i.e, everytime we touch that value. We do so until the solution is satisfactory to some level of accuracy.

It's better to say a guess.

Hello:

Formula for an arithmetic sequence nth term.



{30,28,26,24,22,20,18,16,14,12,10,8} are how the seats are put.

Hello: I think that answer is too much. If you simulate it you will agree.

#19 Re: Help Me ! » Algebra (2?) Problem » 2016-04-09 06:23:35

I missed the post too sad Thanks Relentless.

I didn't simplify sad

I know about Confucius I told you that.

#20 Re: Help Me ! » Algebra (2?) Problem » 2016-04-09 06:11:56

Do you think that Geogebra used a least squares fit?

Mr. m, it looks like you have forgotten the definition of a sector.

What is ETPI?

I can only write a MonteCarlo simulation

ETPI - Exploit The Problem Itself

A simulation is enough for an ansatz smile

Hello Agnishom!

There are ways to solve problems.

i) ETPI ( patent to bobbym ).

ii) Apply Experimental Math to it.

iii) Ask bobbym when the old guy is in a good mood, like after he watches the Walking Dead.

I'll bet you can figure which I chose.
