Is it possible for a figure to have 90° rotational symmetry but not 180° rotational symmetry.
Gre4nikov [31]

Answer:

Well, It is but not because..rotation symmetry, and a square has -turn (or 90-degree) rotation symmetry. As you may have already observed, many figures have 180-degree rotation symmetry but no other rotation symmetry. A figure has 180-degree rotation symmetry if it looks the same when turned halfway around...Soo yeah..I think I am right, So sorry if I'm wrong.

Suppose you spin the spinner and toss a coin. What is the probability of NOT heads and NOT 4? A) 1/8 B) 3/8 C) 5/8 D) 7/8
7nadin3 [17]
I think the answer is B) \frac{3}{8}. You can figure this out by multiplying the possible outcomes of the coin by the spinner (4*2) and find the amount of outcomes that are not what you are looking for (3) and put that over the product. (3/8)

Hope this helps
