Question

Find A u B and A (upside down u sign) B for Set A and B

A= {40,35,45,5}, B= {1-,30,15}
A u B = ?
or
A u B is the empty set

A (upside down u sign) B
A (upside down u sign) B is the empty set

HELP!!!!!

Answer 1

The union of sets is the set that contains all the elements in the first set and the second set
The intersection of sets is the set of elements that appear in both sets

for example:

if \(X=\{a,b,c\}\) and \(Y=\{c,d,e\}\)

the ∪nion of \(X\) and \(Y\)
is
\(X\cup Y=\{a,b,c\}\cup\{c,d,e\}=\{a,b,c,d,e\}\)

The i∩tersectio∩ of \(X\) and \(Y\)

is \(X∩Y=\{a,b,c\}∩\{c,d,e\}={c}\)

Answer 2

So, do i use your example to solve >< sorry i never learned this

Answer 3

\[A= \{40,35,45,5\},\quad B= \{1-,30,15\}\]
\[A \cup B = ?\]

Answer 4

...

Answer 5

A U B = {40,35,45} U {45,30,15} ?

Answer 6

EXAMPLE
NOT YOUR MATH PROBLEM

intersection


WHAT HAPPENS TO INTERSECT
C, D, E, F

EVERY THING THAT HAPPENS TO INTERSECT IN THE AREA DENOTED BY AREA MARKED ( a)

IS THE INTERSECTION OF C, D, E, F

UPSIDE DOWN U

Answer 7

i dont get that

Answer 8

oh ok...

Answer 9

So, what I got as an answer is it correct? Do I just plug what is a,b,c, d...etc?

Answer 10

AUB={1,-30,15,35,45,40,5}

Answer 11

its 10...
