Answer:
3
9
21
Step-by-step explanation:
For the first one use the law of total probability
B=A∩B+A'∩B
12=9+A∩B
A∩B= 3
For this one you should use demorgans law and the union formula
(A'∩B')=(AUB)'
AUB= A+B-A∩B
6+12-3=15
15'= 24-15 = 9
For this one use demorgans law again
(A'UB')=(A∩B)'
(A∩B)'= 24-A∩B= 24-3= 21
Answer:
25
Step-by-step explanation:
y + ( - 16 ) = 9
y - 16 = 9
Add 16 on both sides,
y - 16 + 16 = 9 + 16
y = 25
Answer: 126 cubic inches
To find this answer...
All you simply have to do is to plug in the answers to the volume equation (length × width × height = volume)
The length is 6 inches
The width is 3 inches
The height is 7 inches
6×3 is 18
18×7 is 126
Hope this helps!
