Answer: 1.83
Step-by-step explanation:
Z = (x - mean) / standard deviation
= (97-75) / 12
= 22/12 = 11/6 = 1.83
A function is defined as a mathematical graphical equation, that states that for every value of X there must be one and only one value of y.
For instance the coordinates :
(2,3) and (2,4) do not represent a function, because in both cases the X value is the same and not unique for the points.
Opposite angles are equal so the equation is
x + 71 = 108 (A)
Answer:
the region of the circle in polar coordinate can be expressed as:
Step-by-step explanation:
Given that:

This implies that :

center (5.5, 0) and radius = 5.5
The relation between the cartesian coordinates (x,y) and the polar coordinates (r, θ) is as follows:
x = rcosθ
y = rsinθ
Thus, 



Thus, the angle θ runs between
to
Therefore, the region of the circle in polar coordinate can be expressed as:
