Answer:
Yes, this graph represents a function.
Functions can have a maximum of one y-value for every x-value. On a graph, this means it passes the vertical line test.
Step-by-step explanation:
The vertical line test is when a vertical line is passed though the graph. If at any point the vertical line touch more than one point on the graph, the graph is not a function. Vertical line test is also known as VLT.
Answer:

Step-by-step explanation:
From the question we are told that:
Sample size 
Standard deviation 
Confidence level 
Degree of Freedom 
Therefore
Test T from table is given

Generally the equation for Confidence interval CI is mathematically given by



35) 48 cents each!
36) 297 miles a day!
Answer: y=0.60x+36.94
To find the equation we just set y equal to the 0.60 cents times x miles plus the 36.94 base fee. Any questions just ask. Cheers
