Answer:
D
Step-by-step explanation:
Using the Slope Equation
Pick two points on the line and determine their coordinates.
Determine the difference in y-coordinates of these two points (rise).
Determine the difference in x-coordinates for these two points (run).
Divide the difference in y-coordinates by the difference in x-coordinates (rise/run or slope
Answer: C. 
Step-by-step explanation:
The confidence interval for difference of two population mean is given by :-

Given : Level of significance : 
Then , significance level : 
Critical value : 


Hence, a 99% confidence interval for the difference between the mean wait times of everyone who rode both rides 
Answer:

Step-by-step explanation:
Since the <em>rate</em><em> </em><em>of change</em><em> </em>[<em>slope</em>] is zero, that automatically makes our equation set equal to the y-coordinate of the ordered pair, which in this case is the y-intercept.

Answer:

Step-by-step explanation:
We have the following solution:

We want to find the value of x that satisfies the following condition:
y(3) = 3.
This means that when x = 3, y = 3. So







I think it would be A.) but at the same time i think it's wrong
