Answer:
Smaller x -10
Larger x -2
Step-by-step explanation:
f(x) = (x+6) ^2 - 16
To find the zero's, we set the function equal to zero
0 = (x+6) ^2 - 16
Add 16 to each side
16 = (x+6) ^2 - 16 + 16
16 = (x+6)^2
Take the square root of each side
±sqrt(16) = sqrt((x+6)^2))
±4 = x+6
Subtract 6 from each side
-6±4 = x+6-6
-6±4 = x
-6 -4 = x -6+4 =x
-10 =x -2 =x
Smaller x -10
Larger x -2
Answer:
a) The number of visits between the patrons who buys the season passes shows higher frequency than those who did not buy season passes, in general. However, the minimum value of 1 visit is present for both cases.
b) The mean visits of the patrons are just PARAMETERS. If you want to test your hypothesis using hypothesis testing, the statistics are the z or t scores comparing the parameters (means).
c) The proportion who would have paid less are those with 2 or fewer visits because they would only just paid $82 instead of $100.
Number of patrons with 2 or fewer visits: 16
Total number of patrons who bought season passes: 30
Proportion who would've paid less = 16/30 = 0.5333
