Step-by-step explanation:
Let's simplify step-by-step.
16−3+3q−1.7+−13p+4
=16+−3+3q+−1.7+−13p+4
Combine Like Terms:
=16+−3+3q+−1.7+−13p+4
=(−13p)+(3q)+(16+−3+−1.7+4)
=−13p+3q+−0.533333
Answer:
=−13p+3q−0.533333
First, we find the mean....
(7 + 15 + 11 + 1 + 11) / 5 = 45 / 5 = 9
now we subtract the mean from every data point, and square it...
7 - 9 = -2.....-2^2 = 4
15 - 9 = 6....6^2 = 36
11 - 9 = 2....2^2 = 4
1 - 9 = -8...-8^2 = 64
11 - 9 = 2...2^2 = 4
now we find the mean of those numbers...that is ur varience...
(4 + 36 + 4 + 64 + 4) / 5 = 112/5 = 22.4....rounds to 22 <==

The perpendicular bisector goes through the midpoint.
What is the midpoint of the 2 points?
We simply add up the x points and divide by 2. Then we add up the y points and divide by 2.
So,
Midpoint is:
Also, the perpendicular bisector's slope is the negative reciprocal of the line's slope.
The slope of the line is change in y points divided by change in x points.
Slope =
The slope (m) of the perpendicular line (negative reciprocal) is basically:
Equation of line is:
m is the slope (what we got "2")
x1 and y1 are the respective point where it passes through (which is the midpoint, which is (-3,2)
So, equation of perpendicular bisector is:
