Answer:
a) True
Step-by-step explanation:
The given statement is true.
where are data points,
is the mean and n is the number of observations.
The standard deviation express the variation of data from the mean and therefore, have the same unit as the data like lbs, inches, dollars, etc.
Coefficient of variation on the other hand is the ratio of standard deviation and mean. It is also a measure of dispersion but since it is a ratio, the units cancel each other.
Thus, coefficient of variation is dimensionless.
Thus, it is a relative measure.
Given:
Center of a circle is at point C(-1,2).
AB is the diameter of the circle.
Coordinates of the point A are A(2,6).
To find:
The coordinates of point B.
Solution:
Let the coordinates of point B are (a,b).
If AB is the diameter of the circle, then A and B are end points of diameter of the circle and the center C is the midpoint of AB.
Point C = Midpoint of AB
On comparing both sides, we get
Similarly,
Therefore, the coordinates of point B are (-4,-2).
