Ok the ladder and the ground will make a right triangle/right angle. This is because the ground is flat, the wall is straight and only the ladder is leaning/slanted. I hope this helps.
Use Pythagorus theorem:
a²+b²=c²
(12)²+(16)²=c²
400=c²
√400=c
20=c
Therefore, the hypotenuse would be 20 ft.
Hope I helped :)
Answer:
equation for perpendicular bisector passing through CB is;
y=⁴/³– 5/30
Answer: See description below.
The residuals are the differences between the predicted values and the actual values. You will need to make a scatter plot of each difference.
Here are the five points that you will need to plot:
20 - 21 = -1 (1, -1)
17 - 16 = 1 (2, 1)
9 - 10 = -1 (4, -1)
6 - 5 = 1 (5, 1)
2 - 2 = 0 (6, 0)
that is not possible cause the first 2 indicate that the pattern is counting by 2s
