1) RED will be rotated 90° counterclockwise around the origin.
2) The coordinates of R'E'D' will be R'(2, 2); E'(0, 4) and F'(0, 0). The rule for a 90° counterclockwise rotation about the origin is that the coordinates (x, y) are mapped to (-y, x).
3) An isometric transformation is one in which the angles between sides and the distances of each side are preserved between the pre-image and the image. This means the angle measures and side lengths will be the same. Therefore the image will be similar to the pre-image, as the angle measures will be the same and the side lengths will be proportional.
Answer:
Step-by-step explanation:
No. Of white marble n(W) = 2
No. Of black marble n(B) = 1
Total no. Of marble N = 2 + 1 = 3
Prob(1st is white) = n(W)/N = 2/3
Prob(1st is black) = n(B)/N = 1/3
