Answer: False, there are 12 possible combinations.
<u>Step-by-step explanation:</u>
Each pair of pants matches to each shirt.
She has 3 pairs of pants (1, 2, & 3) and 4 shirts (A, B, C, & D).
Here are all of the combinations:
1A 1B 1C 1D
2A 2B 2C 2D
3A 3B 3C 3D
There are 3 <em>pants</em> × 4 <em>shirts</em> = 12 different combinations
18. P(x then y) = 1/11
19. P(both y) = 5/22
To find the probability of these compound events, we have to multiply the probability of each individual event. Remember, on the second trial, there are only 11 options.
18. 2/12 x 6/11 = 1/11
19. 6/12 x 5/11 = 5/22
The answer is: [B]: " (x - 6)(x - 8) " .

Answer: h = -17.5
Step-by-step explanation:
Move the like-terms together on the right side and the other to the left side.
1.6h - 4h = 72 - 30
Subtract both sides:
1.6h - 4h = -2.4h
72 - 30 = 42
-2.4h = 42
Divide -2.4 by both sides
-2.4h/-2.4 = 42/-2.4
h = -17.5
