Answer:
<h2>a. No, the points are in a curved pattern.</h2>Step-by-step explanation:
The residual values are basically the difference between Given values and Predicted values.
So, the complete table would be
x Given Predicted Residual
1 -2.7 -2.84 0.14
2 -0.9 -0.81 -0.09
3 1.1 1.22 -0.12
4 3.2 3.25 -0.05
5 5.4 5.28 0.12
Now, to make a residual plot, we just need to graph all points formed by x-colum and residual column.
The image attached shows the residual plot.
Therefore, the right answer is a., because in the residual plot you can notice that the points are in a curved pattern, like in a parabola-like pattern.
The area scales with the square of the scale factor: the dilation has a certain scale , the area scales with a factor
.
So, if ABC is scaled by 5 to for A'B'C', the area of A'B'C' will be times the area of ABC.
The other exercise is basically identical.
Answer:
Step-by-step explanation:
This is a really nice line that goes through a lot of grid points (where the lines intersect).
One easy way to find the slope is the phrase "rise over run." "Rise" is the name for vertical motion from point-to-point. "Run" is the name for horizontal motion from point-to-point.
Pick two easy points on the line, say (0, 0) and (1, -1).
If you go from (0, 0) to (1, -1), the rise is -1 -- because you went DOWN 1 unit.
The run is 1 -- because you went RIGHT 1 unit.
The slope is -1.
Cool fact: You'll get the same value if you use any two points on the line.
