I need help I cant decide between two answers B and C
Numbers that are divisible by 4... are they going to be even numbers?
Think about what numbers are in the original set. Even numbers between 1 and 21.
@agent0smith no maybe 2 is but the rest I don't know
x is an even number between 1 and 21. List all even numbers between 1 and 21.
2, 4, 6, 8, 10, 12, 14, 16, 18, 20 do u understand what I am asking?
Now look at B - list all the numbers divisible by 4 between 1 and 21.
I think 2 is one of them
I'm not sure what you're saying. 2 is one of what? This is the original set we're given in the question: {2, 4, 6, 8, 10, 12, 14, 16, 18, 20} B is all the numbers divisible by 4, between 1 and 21 - I'd list them so you can see whether or not it is a subset of the original, if you're unsure.
yes I am unsure I don't know subset
Subset means it's a part of the original set. Eg: if this is set A: {2, 4, 6, 8, 10, 12, 14, 16, 18, 20} and this is set B: {2, 4, 6} Then B is a subset of A, since all the numbers in B, are also in A.
would the answer be D for the question
Look at choice B - list all the numbers divisible by 4 between 1 and 21. Write them all out. See if it's a subset of the original.
2, 8, 12 I think are divisible by 4
There's more...
And 2 is not divisible by 4 :/
16 20 40
List ALL the numbers that are divisible by 4, between 1 and 21.
,4, 8, 12, 16, 20, 24, 28, 32, 36 . . .
"...between 1 and 21"
4,8,12,16 and 20
Now compare to the original set... is that a subset of it? Original: {2, 4, 6, 8, 10, 12, 14, 16, 18, 20} This one: {4, 8, 12, 16, 20}
no I don't think so
so @agent0smith the answer would be D
I mean B
Original: {2, 4, 6, 8, 10, 12, 14, 16, 18, 20} This one: {4, 8, 12, 16, 20} Are all the numbers in the bottom set in the original set?
not all of them
Look at all the numbers in the bottom set. Then look at all the numbers in the original set.
no they are not in the original
Damn dude. Look harder. Original: |dw:1465865719654:dw| This one: {4, 8, 12, 16, 20}
yes the original set has the same numbers as the list made
I don't know why you couldn't see that for yourself earlier... Now look at option C Original: {2, 4, 6, 8, 10, 12, 14, 16, 18, 20} Option C: {6, 9, 12}
I see so C is the answer
@agent0smith is C right
You tell me. Original: {2, 4, 6, 8, 10, 12, 14, 16, 18, 20} Option C: {6, 9, 12} Are all the numbers in option C, in the original set?
no
Tell me which ones are in the original set then, and which ones are not?
6 and 12 are in the original set 9 isnt
I put the answer as C @agent0smith
