Nice! I'm 12 in 7th grade and at school I'm learning Algebra 2 but I skipped 6th,7th and 8th grade math so Algebra was like a whole other world for me last year! I dont have much time to learn new things. I am more into programming though.

:P

Nope. I am 14 yrs old and school is teaching some Algebra 1. I learnt through all those Algebra 2, Geometry, Trigonometry, and Calculus all by myself :)

I started to know Calculus when I was 13.

Dang, your smart! I have no idea how to do this stuff. I'm a beginner in Algebra 2!

This is Calculus. My favourite branch of Mathematics.

Sorry. Too lazy to press the calculator and thanks Alan for correcting my mistake.

cos(180°) = -1, not 1 

What is that!?!

24/60 = 2/5

Too lazy to show work. Ask if you need it.

What do you mean like:

1.23456789 * 10¹⁰

There are 2^6=64 possible outcomes. The probability of getting at most one HEAD is 7/64 so the answer is 1 - 7/64 = 57/64.

We first place the non-math books. There are 4 choices for the first book, 3 choices for the second book, 2 choices for the third book, and 1 choice for the last book. Then we have to put the two math books between the four non-math books such that there is at least one non-math book between the two math books. We see there is a total of 5 openings created by the four non-math books. So the first math book has 5 choices, and the second math book has 4 choices.

So the total number of ways the books can be placed is 4*3*2*1*5*4 = 480

It's Just 11^4 for a student each day(the students can be repeated).

11^4 = 14641

8C1 / 10C3 = 8 / 120 = 1/15

(Tell me if you need more explaining!)

There are 4C3 ways to choose which suit goes first and stuff so thats 4. 

There are 13^3 = 2197 ways to  choose the cards. 

2197*4 = 8788

We can get the second marble to be yellow in two ways: either a white from A (with probability 3/7) then a yellow from B (with probability 6/10), or a black from A (with probability 4/7) then a yellow from C (with probability 2/7). Thus, the probability is:

(3/7)(6/10) + (4/7)(2/7) = 103/245!

Thanks everyone :D

Thanks!

(Which by the way is 189/16384)

18:07    or  6:07 PM

Sorry I think you meant   what time is   9 hr and 50 minutes BEFORE 8:17 AM?

22: 27    or 10:27 PM the previous day

p = nCr(7,2)*(3/4)²*(1/4)^(7-2) → 0.01154

Note:  nCr(7,2) = 7!/(2!*5!) = 7*6/2 = 21

.

Wrong.

Hey Max....

Here is a website you might find VERY useful when you need an integral quickly:

http://www.integral-calculator.com/

I get the following for (a):

.

1*8C6 = 28

6*8C5 = 336

6C2*8C4 = 15*70 = 1050

1050 + 336 + 28 = 1414

Hey Max....you already posted these a few days ago.    There are many possible answers.    You can touch off a fire  and hold a grudge.

What is 692 squared divided by 13.4 to the 2nd power

\( Sorry. \ I \ mistyped. \ \color{blue}Thank \ you \ for \ correcting, \ Melody.\)

\(\large\frac{\color{red}692^2}{13.4^2}=2666.87458231\)

LOL Guest, you serious??
