Answer:
(x)^2+ (y+2)^2 = 49
Step-by-step explanation:
The standard form of a circle is
(x-h)^2+ (y-k)^2 = r^2 where (h,k) is the center and r is the radius
(x-0)^2+ (y--2)^2 = 7^2
(x)^2+ (y+2)^2 = 49
Answer:
18.5
Step-by-step explanation:
Population size:4
Mean (μ): 70.5
Mean Absolute Deviation (MAD): 18.5
Let

Find the equation in terms of y in the form x = f(y).

Replace y by x in the right hand side, which will be the required inverse of the function.
