Step-by-step explanation:
Given that the center of the circle is: (2, -4)
tangent to the line x = -2
The equation of a circle has the following formula:
where a, b is the center and r is the radius
The distance between the circle and the tangent line is:
d = 
= 
d = r so 
= 
= 
the equation of the circle is:
Plug in the 1/2 where the a’s are answer is -3
The z-score counts the number of standard deviations from the mean. Then the meaning in gallons of a difference in z-score is found by multiplying the z-score difference by the value of a standard deviation.
(3 -0)*1.2 = 3.6 . . . . gallons.
The 3rd selection is appropriate.
