Create a set of numbers and call the set N. Describe a subset of N and explain why it is a subset of N.

OpenStudy (anonymous):

need help have to show work

OpenStudy (swissgirl):

Ok let \( N=\{1,2,3,4,5,6,7,8,9\}\)

OpenStudy (swissgirl):

Let the subset of N be called S S is a subset of N if every element of S is an element of N So give an example of S

OpenStudy (anonymous):

ummm confuse

OpenStudy (swissgirl):

Ok we chose \( N=\{1,2,3,4,5,6,7,8,9\}\) right?

OpenStudy (anonymous):

yes

OpenStudy (swissgirl):

Now we need to find a subset Do u know the definition of a subset

OpenStudy (anonymous):

yes it means to make it short

OpenStudy (swissgirl):

kinda but ok So there can be many subsets of N Can you list me one

OpenStudy (anonymous):

i cant

OpenStudy (swissgirl):

So ill give you one example Let S be the subset of N \( S=\{2,3,4,7\} \) As we see every element of S is an element of N Can you give me another example where every element of the subset will be included in the set N?

OpenStudy (anonymous):

ok 1,3,5,7 i guess

OpenStudy (swissgirl):

YAHOOOOO YUP

OpenStudy (anonymous):

:)

OpenStudy (swissgirl):

ok you got the explanation though. you just give the definition of the subset like i gave above

OpenStudy (anonymous):

umm

OpenStudy (anonymous):

a set consisting of elements of a given set that can be the same as the given set or smaller.

OpenStudy (swissgirl):

idk I like to put it this way but your way is correct too Every element of S is included in the original set N and therefore S is a subset of N

OpenStudy (anonymous):

soo can tell me the answer n explain it n show the work

OpenStudy (swissgirl):

Let S be the subset of N S={2,3,4,7} As we see every element of S is an element of N S is a set that consists of elements of N that is smaller than N and therefore S is a subset of N

OpenStudy (swissgirl):

ok I gtg that is the answer

OpenStudy (swissgirl):

Bye
