100% of the rolls would be less than 13. The highest number on one die is 6, so even if you roll 2 dice the sum of both dice will always be lower than 13. 
It's a 1:1 probablility.
        
             
        
        
        
Domain is 1 to 6 and length of 5
Because it comes from the x values
        
             
        
        
        
The table tells us that the x coordinate. It also tells us that y is always x + 1.
For #1 you plot the coordinate (0, 1).
0 (the x coordinate) is given to us already.
1 (the y coordinate) is needed to be found by the equation.
You would then need to fill in the equation given with the x coorident. 
y = 0 + 1 
Then, solve for y.
0 + 1 = 1
The y coordinate is 1
Go to the horizontal line (x) and find 0.
Then go to the veridical line (y) and find 1.
Then match up the the x and y to plot the coordinate.
You would continue with this equation with the rest of the xs. 
This is a hard concept to explain in just words, so feel free to comment with any more questions. :D
        
             
        
        
        
Answer:
268.40
Step-by-step explanation:
We can write a ratio to solve
2.5 meters        22 meters
-----------------  = --------------
30.5 dollars       x dollars
Using cross products
2.5 * x = 30.5 * 22
2.5x =671
Divide each side by 2.5
2.5x / 2.5 = 671/2.5
x =268.4
 
        
             
        
        
        
Answer:

Step-by-step explanation:
There was no figure but the question is clear
Volume of a cylinder is given by the formula 
 
where r is radius of base of cylinder, h is the height
Volume of a cone is given by 
where r is the radius of base of cone, h is the height
The radius of the cylinder = 
(diameter) = 
(12) = 6cm
Height of cylinder = 15cm
Volume of cylinder 
Radius of cone = 
 (radius of cylinder) = 
(6) = 3 cm
Height of cone same as height of cylinder = 15cm
Volume of cone, 
Difference is the volume of the remaining solid
