Answer:

Step-by-step explanation:

Recall that two events A,B are called mutually exclusive if and only if A\cap B = \emptyset (their intersection is empty). They are exhaustive if they are mutually exclusive and their union is the sample space.

Based on this

a) Note that A\cap B = \{1,6\}, so they are not mutually exclusive nor exhaustive.

b) A\cap C = \{1\} so they are not mutually exclusive nor exhaustive.

c) A\cap D = \emptyset, so they are mutually exclusive. Note that A\cup D = \{1,2,3,4,5,6\}=S. Then they are exhaustive.

d) B\cap C = \{1,5\}, so they are not mutually exclusive nor exhaustive.

You might want to stick to at most five questions at once, makes it easier for the rest of us. :)

17. T has a vertical line of symmetry (along the center line).
18. Z looks the same if you turn it halfway around.
19. The passes total to 150°, which is a little less than 180°, so I estimate it would be in front of Kai.
20. Left is the -x direction. Up is the +y direction. this is (x-6, y+4)
21. Every dilation has a center (where it's dilated from) and a scale factor (how much it's dilated).
22. It must be A, because it's the only one where the number of moves adds up to 16.
23. It can be determined to be B just by tracking where point C would end up through the transformation.
24. A 180° rotation flips the signs on both components to give you (-1, 6).
25. Right is the +x direction. Down is the -y direction. (x+3, y-5)
26. This is a reflection.
