2) S

Total=23

20+ H- X=23

34- X= 23

-23+x= 23

11= x

9-only Sang

11- Sang and dance

3) u=32

17+15=32

17+15-x=22

32-x=32

10=x

n(AnB)=10

n(AnB')=7

4) A={X∈Z-, -5

Set A containing in the set of all X which is an element of negative integers where X is greater than -5 and less than +2.

b) Elements of A:

{-4,-3,-2,-1,0,1}

c) Finite

5) If u={x| x∈ Z, 0≤ X ≤ 15}, A={multiples of 3 less than 16}, B={prime numbers less than 16} list the element of :

A: { 0, 3,6,9,12,15}

B: { 2,3,5,7,11,13}

B'={0,1,4,6,8,9,10,12,14,15}

AUB ={0,2,3,5,6,7,9,11,12,13,15}

AnB'={0,6,9,12,15}

Question: Is 0(Zero) a infinite or finite number?

Homework for today :

study for re-take test

Hint or suggestion :

Try your hardest and study for tomorrow

Questions:

What do you think would be the most difficult part of the test tomorrow ?

the blog for November 2 2010

What we did.
Bell ringer
Review Homework

Bell ringer: Draw a ven diagram
U=(2,4,6,8,10,12,14,16,18,20)
A=(2,4,6,10)
B=(6,10,12,14)

We had to find
AnB
A'uB
An'B
1.n(AnB)=2
2.n(A'uB)=8
3.n(An'B)=2

Than reviewd homework that was on page 77



H.W. Due November 3
pg 78 1-4

Question: Do you understand the ven diagram? And when is my b-day?



Sorry that its late.

IB Math Studies 11/1/10

Bellringer

Represent A and B in a venn diagram given

u= {1,2,3,4,5........20}

A= {5,10,15,20}

B= {3,6,9,12,15,18}



Agenda

1. Bellringer
2. Homework Review
3. regions in venn diagrams

Objective: Students will use venn diagrams to illustrate venn diagrams

Big Picture

Venn diagrams illustrate the relationships of sets


Question: What is a region of a venn diagram
