Answer:
C) Skewed Left
Step-by-step explanation:
From the above histogram given, it can observed visually that fewer students spent less hours in Mr. Quentin's class engaging in the online research for the project, while majority of the students spent more hours.
Thus, the histogram is skewed to the left, having a non symmetric shape with a lopsided mound which is bigger on the left of the histogram and smaller to the right of the histogram, as we have few students who spent less hours compared to the vast majority that spent more hours on the research.
First, distribute the minus sign across the second set. So you have:
x - y + 1 - x - y + 1
Now, we combine like terms:
x-x=0
-y-y=-2y
1+1=2
So we have -2y+2
Hope that helps.
I believe it is 0.7
Step-by-step explanation:
or it is -0.7
So it can now be bought for 65% of its regular price.
That's a good deal. If I needed a clearance rack, I'd buy it.
Answer:
D. (x, y) → (x, −y)
Step-by-step explanation:
Transformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, translation, rotation and dilation.
The orientation shows how an object is arranged. Rotation, translation and dilation preserves orientation while reflection does not preserve orientation.
The transformation (x, y) → (4x, 4y) shows the dilation by a scale factor of 4. Dilation preserve orientation.
The transformation (x, y) → (−y, x) shows the rotation of a point 90 degrees counterclockwise. Rotation preserve orientation.
The transformation (x, y) → (14x, 14y) shows the dilation by a scale factor of 14. Dilation preserve orientation.
The transformation (x, y) → (x, −y) shows a reflection over the x axis. Reflection does not preserve orientation.
