Answer:
7x -2y = 6
Step-by-step explanation:
The perpendicular bisector has a slope that is the opposite of the reciprocal of the slope of the segment between the two points. It must go through the midpoint of the segment.
The latter can be found by averaging the coordinates of the end points:
((-5, 6) +(9, 2))/2 = ((-5+9)/2, (6+2)/2) = (2, 4)
The difference in endpoint coordinates is ...
(Δx, Δy) = (9-(-5), 2-6) = (14, -4)
For our purpose, we're only interested in the ratio of these values, so we can divide both by the common factor of 2:
(Δx, Δy) = (7, -2)
A line perpendicular to this segment through the point (h, k) can be written as ...
Δx·x +Δy·y = Δx·h +Δy·k
7x -2y = 7(2) -2(4)
7x -2y = 6 . . . . . . . standard form equation for the perpendicular bisector
Answer:
Step-by-step explanation:
Given that the sitting back-to-knee length for a group of adults has a normal distribution with a mean of mu equals 22.1 in. and a standard deviation of sigma equals 1.2 in.
We have to find values of x such that
and
a=2.33 and b =-2.33 as z values
Let us convert to X values
i.e. values below 19.304 and above 25.496
Hence for x below 19.304 and above 25.496 are significantly low and high.
24.2 length is not significantly high.
Answer:
Step-by-step explanation:
<u>Given</u>
- x = {5, 6, 7, 8, 9} and
- y = {33, 39, 45, 51, 57}
<u>The equation in slope- intercept form:</u>
<u>Using two pairs of coordinates (5, 33), (6, 39), we will find the slope:</u>
- m = (39 - 33)/(6 - 5) = 6/1 = 6
<u>Using one point (5, 33) to find the y-intercept:</u>
- 33 = 6*5 + b ⇒ b = 33 - 30 ⇒ b = 3
<u>The equation is:</u>
Correct option is B
