<span>You can get those ordered pairs subtracting 9-0.5, then that result minus 0.5 because from the rate the candle reduces its height 0.5inches per each hour.Part B: Is this relation a function? Yes, because each value of x has a single result or output in “y” (image)Part C: Yes, only difference is the time, the candle reduces its height 0.45 inches per each hour, examples of ordered pairs: (0,9) (1,8.55) (2,8.1)</span>
Answer:

Step-by-step explanation:
Let the unknown angle be x
As the interior angles in a triangle are added up to 180°

Answer:
These numbers are - parameters.
Step-by-step explanation:
A study of all the students at a small college showed a mean age of 20.9 and a standard deviation of 2.9 years.
These numbers are - parameters.
These numbers are parameters as they are for all the students, and merely not a sample.
By computing x=3600 * 1/ 57.1= 63.047 miles per hour
The y-intercept of f(x) is f(0), i.e. the value of f(x) when x=0.
y-intercept=f(0)=2(0)-1 =-1
Since g(x) is not given, we cannot determine its y-intercept.
