Answer 1

help me plzzz

Answer 2

B! What do you need help with?

Answer 3

5 questions

Answer 4

Okay, I'll help! What are the rest? First though, want me to explain this one?

Answer 5

yes

Answer 6

Okay, so "even" numbers are basically those that can be divided by 2, and still return an integer [counting number, but also includes negatives, like 1, 2, 3, 4 and -1, -2, -3, -4, etc.]. Now, in set notation, we have a set that describes all of the numbers that are even [divisible by two] and lead from 1 to 11. First, here's the set of all numbers from 1 to 11: n[I chose to assign "n", but choose whatever you want to]={1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11}. Okay, now here's the set of even numbers [going to infinite essentially]: e[once again, I chose e, but do what you want]={2, 4, 6, 8, 10, 12, 14, 16, 18, 20, ... , etc.}. Now, we want the Union of these 2 sets [essentially, the set that contains all of the numbers that are in BOTH sets; here is how you write that: nUe [Union of sets n and e] = {2, 4, 6, 8, 10}. Any questions?

Answer 7

no

Answer 8

heres the other onee

Any questions?

Answer 10

What is the intersection of the sets A = {2, 3, 5, 7, 11} and B = {5, 11, 13, 15, 17}?



A.


{2, 3, 5, 7, 11, 13, 15, 17}


B.


{5, 11}


C.


{2, 3, 5, 7, 11}


D.


null set

Answer 11

OKAY, I MADE A MISTAKE. When I said Union, I actually meant to write "intersection". An Intersection of 2 sets is the combination of elements in BOTH sets. I apologize. The Intersection of sets n and e [represented as an Upside Down U] = {2, 4, 6, 8, 10}. Is this clear before I answer your above question?

Answer 12

yes

Answer 13

so the other is still right??

Answer 14

Okay, so what we want for your above question, is the set that contains elements ONLY that are in BOTH sets. Do you think you can do it?

Answer 15

Yes, the other is still correct. I just accidentally used the wrong term. I accidentally said "Union" but I meant to say "Intersection". Intersection is when you only include elements from BOTH sets.

Answer 16

kk

Answer 17

so now we on this question

Answer 18

What is the intersection of the sets A = {2, 3, 5, 7, 11} and B = {5, 11, 13, 15, 17}?



A.


{2, 3, 5, 7, 11, 13, 15, 17}


B.


{5, 11}


C.


{2, 3, 5, 7, 11}


D.


null set

Answer 19

@faysal96 y u leave

Answer 20

@dan815 can u help me

Answer 21

Okay, so since set A = {2, 3, 5, 7, 11}, and set B = {5, 11, 13, 15, 17}, take the elements that are only in BOTH, {5, 11}. Does this make sense to you?

Answer 22

no

Answer 23

So basically, a set is a bunch of numbers, right? Think of it like a bucket filled with different fruits [apples, oranges, pineapples, grapefruits, watermelons, etc.]. So we have 2 buckets, and let's say the first bucket has an apple, a grapefruit, a watermelon, a banana, an orange, and a pineapple. The second bucket has a watermelon, a kiwi, a banana, a pineapple, and a coconut. "What is the intersection of these 2 sets?" This is really just asking, what do both buckets have in common? The answer is a watermelon, a banana, and a pineapple! So the intersection of Bucket 1 {apple, grapefruit, watermelon, banana, orange, pineapple} and Bucket 2 {watermelon, kiwi, banana, pineapple, coconut}, is the following set: {watermelon, banana, pineapple}. Does this make sense? The above question is basically the same thing, but you are just using numbers instead of names of fruit!

Answer 24

yes

Answer 25

im on another 1 now

Answer 26

Okay, anything else?

Answer 27

What is the intersection of the three sets: A = {0, 2, 3, 6, 8}, B = {2, 3, 6, 8, 9}, and C = {1, 2, 4, 8, 9}?



A.


{2, 8, 9}


B.


{2, 6, 8}


C.


{2, 8}


D.




{0, 1, 2, 3, 4, 6, 8, 9}

Answer 28

So again, take what you see that is in ALL THREE sets, and make that a new set. Can you do it?

Answer 29

Like what's in common with all 3 sets?

Answer 30

This table shows the top athletes that play both football and baseball.



What is the intersection of the set of football players and the set of baseball players?


02_02_LQ_5.gif



A.


Intersection: {Jackson, Peavey}


B.


Intersection: {Peavey}


C.


Intersection: {Jackson}


D.


Intersection: {Adams}

Answer 32

Again, take a look at the left hand side [the set of all football players] and the right hand side [set of all baseball players] and find what's in common with BOTH. Does that make sense?

Answer 33

yes so is it ABCD

Answer 34

Jackson and Peavey, so that would be A.

Answer 35

oh
