Answer:
The standard deviations is 
Step-by-step explanation:"
Given mean female height = 64 inches and standard devaiton = 3 inches and 69 inches tall is Sally.
We know the distance of a data point from:
Z =
=
So the standard deviations is
Answer:
0/2 is ZERO is positive
Step-by-step explanation:
The perpendicular bisector of the segment passes through the midpoint of this segment. Thus, we will initially find the midpoint P:
Now, we will calculate the slope of the segment support line (r). After this, we will use the fact that the perpendicular bisector (p) is perpendicular to r:
We can calculate the equation of
p by using its slope and its point P:
C
