Help with math homework

Well, the combinations will be 19 + 18 + 17 and so on, the once you get to adding one, you need to multiply that by 4 then multiply that by 0.50 and then there is your answer.
I think I did that wrong :v

 

I think it's 204 So, 20x20x20x20 Because you have 20 numbers and that's 160000 combinations. $0.50 for every combination makes it 160000:2 = $80000 (I hope that's right I always forget how you do this Dx)

 

$7

Don't question it
Best guess somewhere around $50k

 

Well tell me the topic (Is it factorial ; Laplace experiment etc.?).

 

0.50 for 1 ticket (Or 4 numbers)
w,x,y,z
w being number 1 and so on.
w,x,y,z is one single ticket which costs half a dollar or .50
The number can go up to 20.
There are 4 numbers
There are 20 possible solutions for each possible number per ticket.
20*20*20*20=160000

Now each ticket costs .50 so 160000*.50 or 1/2

so $80,000.

This means that @patrickdemooij9 was right.

Hope we helped, anything else just ask (Unless it's Calculus, Precal, etc. xD )

 

We all welcome you c:

 

Is that your math homework?

What math are you in?

I'm in Honors Algebra 2.

In 9th grade.

My math homework happens to be like:

EDIT;

Not to mention AP NSL, Honors Chemistry, and Honors Spanish 4.

All in 9th grade.

:V

It's not easy.

 

I'd beg to differ... All it is is using quadratic formula, matrix algebra, and simplifying... XD
Try proving golden ratio :V

 

EDIT:

WTF that quote did not work

 

McBrawl = HW help, yet Minecraft community. wattttttt

 

I'm 15.
= 1/2 (1+sqrt(5))

 

im also in grade 9 and that isnt very hard for me

 

Cool.

 

Solve x² - 12x = 28 //-28



x²-12x - 28 = 0

x 1/2 = -p/2 ± √ (p/2)² - q

x1/2 = +12/2 ± √ (12/2)² + 28

x1/2 = 6 ± 8

x1 = 14
x2 = -2


You can also use the quadratic formula

Answer: D
multiple choice is so easy :3

 

LOL LMAO THIS IS NOTHING COMPARED TO WAT I GOT LEL

AND I MEAN NOTHING LOLOLOLOLOLOLOLOLOL

and at choci nobody uses completing the square anymore its all about teh golden equation

(no offence)

 

The golden equation being quadratic I assume? If that is what I think you're saying... You're an idiot hue.
Do you know why quadratic works? Quadratic = completed square ax^2+bx+c ;v

 

Solving with the equation doesn't mean using the completing the square method. You derive the equation from completing the square however using the formula doesn't mean that u are using that method skidiot
and on teh side note, wtf does Quadratic = completed square ax^2+bx+c mean?
Quadratic equation = ax^2+bx+c = 0
Quadratic formula = what choci said 2 lazy to get teh image
u get the formula by completing the square of the quadratic equation, quad equation <> completed square of ax^2+bx+c = 0
