A relation is a relationship between sets of values. In math, the relation is between the x-values and y-values of ordered pairs. The set of all x-values is called the domain, and the set of all y-values is called the range.
Answer:
This question overall depends on a continuously changing factor.
Step-by-step explanation:
There are many houses in this world that have an area of less than 100 
, while many others have up to 700, 800, or even 1000 of land. Your question is impossible to calculate because of the massive amount of houses in this world. If you want a good estimate, say around 0.9 to 1.8 billion.
Get a ruler. and do 8 lines with maybe each being 2 inches.
To solve a quadratic equation like 
, you can use the quadratic formula
In your case, 
, so the formula becomes
We can simplify the expression:
Since -3 is negative, its square root is computed as
So, the solutions are
<span>The correct answer is 1/78.
Explanation<span>:
There are 2 orange marbles out of 13 total marbles, so the probability of your first marble being orange is 2/13.
After this one is drawn, since it is not returned, the probability of getting a second orange marble is 1/12, since there is only 1 orange marble left out of 12 total marbles.
This gives us the total probability 2/13(1/12)=2/156=1/78.</span></span>
