Answer:
ABCD ≅ A'B'C'D'
Step-by-step explanation:
When a figure is rotated, its orientation stays the same. This means that the pre-image and the image are labeled in the same direction. Therefore, ABCD ≅ A'B'C'D'
I don't have a visual I can provide, but the ratio of the areas is the square of the ratio of the perimeters of a 2D figure.
Intuitively, you can imagine that the triangle is simply being "scaled up" by a factor of 7/3, so the base scales up to 7/3 its original length and the height becomes 7/3 its original height.
Therefore, the new ratio is the square of the ratio of the perimeters, which is 9:49.
The answer is no, I think
Answer: Usually the mean is more accurate without outliers.
Step-by-step explanation: Outliers can skew the data, or make it inaccurate. So without the outliers, the mean is more accurate.
hope this helps
