which set is from 1 to 30???

jenniferjuice · Answer

5 10 15 20 25 30

ivettef365 · Answer

ok, which set includes those numbers ??

ivettef365 · Answer

the first set shows
{5,10,15......} this one means indefinite numbers after 15, so NOT GOOD

ivettef365 · Answer

which one you think is the correct answer ?

jenniferjuice · Answer

{integers divisible by 10 from 1 to 50}

jenniferjuice · Answer

maybe...

jenniferjuice · Answer

@amistre64 can you please help me with this?

ivettef365 · Answer

it can not be { integers 10 from 1 to 50} because the integers can only be from 1 to 30

amistre64 · Answer

A = { 5 10 15 20 25 30 }

a subset of A can only contain some or all the elements of this set.  so it cant be any bigger than this set

the first option is infinite,  which is always bigger than 6 elements
the third option contains elements that are not in A, so it cant be it
the last option contains elements that are a part of A ....

ivettef365 · Answer

it can not be {30m35,40} because 35 and 40 is already more than 30

jenniferjuice · Answer

so would it be 10,15,20 ?

amistre64 · Answer

are 10, 15, and 20  elements of A?

jenniferjuice · Answer

yes because it says integrrs from 1-30

amistre64 · Answer

then that would be it :)

jenniferjuice · Answer

alrighty thankyou :)
