Create a set of numbers and call the set N. Describe a subset of N and explain why it is a subset of N. sleek-feathered onesss help meee.

jimthompson5910 (jim_thompson5910):

Think of any 5 numbers you want

OpenStudy (anonymous):

uhmm. 2,4,6,8,10.

jimthompson5910 (jim_thompson5910):

ok so let's make set N = {2, 4, 6, 8, 10}

OpenStudy (anonymous):

alright. now what?

jimthompson5910 (jim_thompson5910):

a subset of N will be a set that has numbers in it that are found in set N so let's say we make the new set M = {4, 10, 6} the numbers 4, 10, and 6 are all in set N so set M is a subset of set N

jimthompson5910 (jim_thompson5910):

if we decided to add the number 7 to set M to get M = {4, 10, 6, 7} set M is no longer a subset because the number 7 is in M, but it's not in N

OpenStudy (anonymous):

Im confusedddd

jimthompson5910 (jim_thompson5910):

where are you stuck?

jimthompson5910 (jim_thompson5910):

think of it like this say this circle here represents set N |dw:1365389142441:dw|

OpenStudy (anonymous):

Like I dont know what im even supposed to do for this. Can you give me the complete answer?

jimthompson5910 (jim_thompson5910):

in this circle will go the numbers 2, 4, 6, 8, 10 |dw:1365389167049:dw|

jimthompson5910 (jim_thompson5910):

a subset will represent any shape that is completely within this circle N, so here's the subset {4, 10, 6} |dw:1365389221239:dw|

jimthompson5910 (jim_thompson5910):

hopefully that's clearer?

OpenStudy (anonymous):

What am i supposed to write for the question?

jimthompson5910 (jim_thompson5910):

just two sets really set N and a subset of N
