Question 1 (Multiple Choice Worth 5 points)

[3.02] If A = {integers divisible by 2} and B = {integers}, what is A ∩ B?

{…−3, −2, −1, 0, 1, 2, 3 …}

{ }

{0}

{… −6, −4, −2, 0, 2, 4, 6 …}

Answer 1

Someone help me please

Answer 2

is that called A intersect B ?

Answer 3

yes A ∩ B means interact and it means "and". so you have to combine the two. It would be the last answer because the "A" set represents all the number DIVISIBLE by 2 and the "B" set represents integers. And because it's integers and divisible by 2.

Negative numbers are also integers

Answer 4

lol that's the one I had thankss for the help..

Answer 5

Was I correct?

Answer 6

B is the set of integers, and A is the set of integers divisible by 2, that mean A only have even integers , so A is a subset of B...what do you think when the 2 sets intersect ?

Answer 7

vmisono yes, you were right... thanks.

Answer 8

of course :)
