The probability would be 1/4 for hearts 1/13 for the number card I think this is right sorry if it’s not
        
             
        
        
        
If it's for a graph then I believe you just find the slope which you can do by taking two points and plugging them into this equation y-y
/
X-X
Example: (2, 4) and (6, 7) the first number is always x and the second is always y so if you plug those in the equation would look like this....
4-7
/
2-6
That would end up being
 3
- ---- aka the rate of change 
 4
P.s. The slash and the four dotted lines together means division. Hope this helps 
        
             
        
        
        
Answer:
The standard form of  is 0.0000002
Step-by-step explanation:
 
        
             
        
        
        
The area of a square is expressed as:
Area = s^2
We are given the area of both windows. We will use this value for the calculations. We set s as the side of the larger window and a for the smaller window.
Total area = Area larger + area smaller
1025 = s^2 + a^2
Since it was said that the side of the larger window, s is 5 in longer than the side of the smaller window, a (s = 5+a) then:
<span>1025 = s^2 + a^2
</span>1025 = (5+a)^2 + a^2
simplifying we obtain,
a = 20 inches
