There are 35 ways to roll 2 dice. That is from 2 to 36.

For the dice to sum to 10 there are 3 ways to roll a 10 so that is 3/35 = 0.0857

For the dice to be doubles there are 6 ways so that is 6/35 = 0.171

The question ask for either to sum to 10 or have doubles so that is 6 + 3 = 9 ways and

9/35 = 0.257. That is the probability, 

I do the last question because it say “and” instead of “or”.  

The sum of the pips on the top faces is 6 and doubles are rolled?

There is only one way to get a total of 6 with a double and that is with two 3s that is 1/35 or 0.286. 

You can do the others questions now. 

Here's the formula for it

Y2-Y1

----------

X2-X1

Can you figure it out from here? :)

Please let me know if you cant

Aww, I'm sorry!!!

yess ty but i ran out of time for the test we were taking :(

find the value(s) of (cos^-1 (sqrt(2/2)

cos^-1 (sqrt(2/2))=0

thanks Melody! very easy question i just didn t red the question carefully

Algebra book cost x
geometry book cost y 
2x+3y=34
3y=-2x+34
y=(-2/3)x+34/3 
3x+2y=36 
substitute y in the equation 

3x+2((-2/3)x+34/3)=36 
3x-(4/3) x +68/3=36 
multiply equation by 3 
9x-4x+68=108
5x=40
x=8 , algebra book cost 
plug x in equation 2x+3y=34 to get y=6

Was I helpful at all? (:

I do not know how you expect us to help you, Guest, If you don't reply to what we are asking... :/

* smiles big* :D

ok and hi

Yes, I was confused as well

What do you mean by "back up the tax"? You mean "add" the tax? Or what?

Hiiiiiiiiiiiiiiiiii, and i did what you told mehh

Whoever has read this, thank you :)

ohh, okay!

Great, thanks for telling me! (:

D( x )

5*x-7 = 0

5*x-7 = 0

5*x-7 = 0

5*x-7 = 0 // +

7 5*x = 7 // : 5

x = 7/5

x in (-oo:7/5) U (7/5:+oo)

y = 3/(5*x-7) // - 3/(5*x-7)

y-(3/(5*x-7)) = 0

y-3*(5*x-7)^-1 = 0

y-3/(5*x-7) = 0

(y*(5*x-7))/(5*x-7)-3/(5*x-7) = 0 y*(5*x-7)-3 = 0

5*x*y-7*y-3 = 0

(5*x*y-7*y-3)/(5*x-7) = 0

(5*x*y-7*y-3)/(5*x-7) = 0 // * 5*x-7

5*x*y-7*y-3 = 0

5*x*y-7*y-3 = 0 // + -7*y-3

5*x*y = -(-7*y-3) // : 5*y

x = (-(-7*y-3))/(5*y)

x = (3-(-7*y))/(5*y)

x = (3-(-7*y))/(5*y)

Like that??

Hi Hayley

He put 25 in there because he use the complete the square method to solve this.

You do that by taking half the middle term coefficient which is 10 part of the 10 x here so that becomes 5. Then you square that so it becomes 25. You have to add it to both sides so the equation balance.

how are you wanting this answered? By the slope? 

1 - 82%=18% chances that loses in one game.

18%^5=0.01889568% chances of losing all five games.

11/9=1.22 rounded to nearest hundredth.

n | 1 | 2 | 3 | 4 | 5........................etc.
n (n+1) | 2 | 6 | 12 | 20 | 30........etc.

Therefore 210 is the 14th term, because 14 X (14+1)=210

Wouldn't you do.. like.. 82% + 5, Or 82% - 5??

I'm not very good with these, yet.

On my knees, I'll ask last chance for one last dance
'Cause with you, I'd withstand
All of h**l to hold your hand
I'd give it all I'd give for us
Give anything, but I won't give up
'Cause you know, you know, you know

I love youu, I have loved you all along... XD
