Consider the universal set U and the sets X, Y, Z. U={1,2,3,4,5,6} X={1,4,5} Y={1,2} Z={2,3,5} What is (Z⋃X′)⋂Y?
beks73 [17]
X' = U - X
= {1,2,3,4,5,6} - {1,4,5}
= {2,3,6}
(ZUX') = {2,3,5} U {2,3,6}
= {2,3,5,6}
(Z⋃X′)⋂Y = {2,3,5,6} ⋂ {1,2}
= {2}
You can do 4 to the second power and 4×4 equals 16

Answer:
I don't know for sure, but there are a bunch of different options. Here they are:
Step-by-step explanation:
1 + 39
2 + 38
3 + 37
4 + 36
5 + 35
6 + 34
7 + 33
8 + 32
9 + 31
10 + 30
11 + 29
12 + 28
13 + 27
14 + 26
15 + 25
16 + 24
17 + 23
18 + 22
19 + 21
20 + 20
Those are the options of how many volcanoes that they could have visited. They could have visited 23 volcanoes in Alaska and 17 in California. Who knows?
California only has 20 volcanoes, and Alaska has 40, so your answer will be one of these options. Hope this helps!
1 mile = 1760 yards
20 * 1.151 = 23.02
23.02 * 1760 = 40,515.2
40,515.2 / 60 = 675.243~
675.243~ / 60 = 11.2542~
They are traveling 11.25 yards per second
I took the number of knots multiplied by the approximate miles per hour equal
Then multiplied that by the number of yards in a mile, and then divided that by the number of minutes in an hour, and divided that by the number of seconds in a minute. That is how I got the answer, I hope it helps!
