Two numbers are randomly selected on a number line numbered from 1 to 9. Match each scenario to its probability. Tiles the proba
bility that both numbers are greater than 6 if the same number can be chosen twice the probability that both numbers are less than 7 if the same number can be chosen twice the probability that both numbers are odd numbers less than 6 if the same numbers cannot be chosen twice the probability that both numbers are even numbers if the same numbers cannot be chosen twice

Step-by-step explanation:
- Re-write the expression:
÷
- 31/6 ÷ 7/10 = 31/6 × 10/7
- 310/42 = 155/21

We are given the following functions:
We are asked to determine the composite function:
The composition of functions is equivalent to:
Therefore, we replace the value of "x" in function "f" for the function "g", therefore, we get:
Since we can't simplify any further this is the composition.
Now we are asked to determine the domain of this function. Since we have a square root, the domain must be the values of "x" where the term inside the radical is greater or equal to zero, therefore, we have:
Now we solve for "x" by subtracting 6 from both sides:
Therefore, the domain is:
