Answer 1

Answer: Well I don't know !
Let's take a look and see:

The idea is that there could be more than one way
for a roll of the dice to land with the same number.

-- If the sum is from 1-4, you get the point.
There are 6 different ways for a roll of the dice to come up 1-4.

-- If the sum is from 5-8, Adam gets the point.
There are 20 different ways for a roll of the dice to come up 5-8.

-- If the sum is 9-12, Lana gets the point.
There are 10 different ways for a roll of the dice to come up 9-12.

-- The game is not fair to all three of you.
-- Lana has a distinct advantage over you.
-- Adam has a big advantage over Lana.
-- Adam has an even bigger advantage over you.
-- You are at a big disadvantage. (Notice that one of your
numbers ... 1 ... can never come up unless one of the dice
falls off of the table.)

Answers

X-3/8=3/6
Add 3/8 to both sides, to leave the variable alone
X= 3/6-3/8
Use common denominators-8 (3/6 is 1/2)
X= 4/8-3/8
X=1/8

A jar contains 4 red marbles, 4 green marbles, and 5 blue marbles.If we choose a marble, then another marble without putting the first one back in the jar, what is the probability that the first marble will be blue and the second will be green?

Answers

Answer:

20/156 or 5/39

Step-by-step explanation:

the first part of the equation will be:

5/13 (5 is how many blue and 13 is altogether)

the next part of this equation is the green marble. Because we didn't put the blue marble back, the next part of the equation will be:

4/12 (4 is how many green and 12 is altogether now that one blue was taken out)

and from there, you multiply 5/13 with 4/12, with will give you 20/156, or 5/39 if you simplify.

4x^2 +28x -32 =0 solve this problem?

Answers

$4x^2+28x-32=0 \ \ \ |:4 \n\n x^2+7x-8=0 \n\n x^2+8x-x-8=0 \n\n x(x+8)-(x+8)=0 \n\n (x+8)(x-1)=0 \n\n \nx+8=0 \n\n \boxed{x=-8} \n\n\n x-1=0 \n\n \boxed{x=1} \n\n\n \boxed{\boxed{S=\{-8;1 \}}}$

we know that if xy=0 then x or/and y=0

4x^2+28x-32=0
factor out the 4
4(x^2+7-8)=0

factor out the x^2+7-8
we must find out what two numbers multiply to get -8 and add to get 7
the numbers are 8 and -1

so 4[(x-1)(x+8)]=0

we know that if exg 4y=0 then y=0
so
therefor
(x-1)(x+8)=0
set each to zero
x-1=0
x=1
x+8=0
x=-8

x could be 1 or -8
