You don't list the "sums listed below" but I can still help you.
There are 6 ways to get a sum of 7 using a pair of dice:
1+6
6+1 You might be asking why 2+5 isn't the same as 5+2
2+5 Imagine the dice are different colors. Is a red 2 and green 5 the
5+2 same as a green 2 and red 5? (No, it's not)
3+4
4+3
You need two numbers that also provide 6 ways to win. One pair that would work is 11 and 9 There are two ways to make 11 (5+6) and (6+5) and there are four ways to make 9 (3+6), (6+3) (4+5) and (5+4) - that's a total of six ways. So to balance your friend's 7 - you could go for sums of 11's and 9's. Check the choices you were given and find the numbers (it could be three numbers like 2,3, and 12) that give you 6 ways to win.
Here are the numbers and their ways

Answer:
0.05620372795
Step-by-step explanation:
use a calculator and type the numbers in then round to the nearest tenth so 0.06 or 0.057
You will need three roots for this, so we have
Let x = -30, -10 and +20
So the factors will be (x+30)(x+10)(x-20)
The divide it to 100, this will help bring the peak up and down
So the polynomial function R(x) will become
1/100 * (x+30)(x+10)(x-20)
R(x) = 1/100 * (x+30)(x+10)(x-20)
Finding the X-intercept:
Let R(x) = 0 and solve for x.
1/100 * (x+30)(x+10)(x-20) = 0
x = -30, -10, 20 are the x-intercepts.
Answer:
- y = 3x + 4
- y =
x - 1 - y = 4
- undefined
Step-by-step explanation:
Slope-intercept form is written in the form: <em>y </em>=<em> mx </em>+<em> b</em>. Leave the y and x as they are. The m is the slope of the graph. The b is the y-intercept of the graph. For number three, the slope of a horizontal line is 0. For number four, the slope of a vertical line is undefined.
Hope it helps! (I'm not sure if you need the answers to the bottom questions).
