1. If A= (2,4,5), B= (1,2,4,7) then what represent A.?

Question

2.which of these sets are infinite?
a. (0,2,4,..),b. (...,-4,-2,0), c.(0), (20,22,24..)
3. If N=(1,2,3,..) then a. (-2 is a element of N)
b. 15 is not a element of N
c. 1/3 is an element of N
d. 2 is an element of N.
Choose the correct answer.
4.W= {0,1,2,3,..}Name the subset of this.
5.A= {1,2,3,4}
B=(1,2,3,4,5,6,7,8,9,)
is A equal to B
6.Name the subset for (1,3,5,7,9...}
7.A=(a,b,c), B=(c,d,e)
Then what is the intersection of A & B is?

Answer 1

1.A is a tripleton set
2.which of these sets are infinite?
a. (0,2,4,..),b. (...,-4,-2,0), c.(0), (20,22,24..)
sets a, b and d
3. If N=(1,2,3,..) then a. (-2 is a element of N)
b. 15 is not a element of N
c. 1/3 is an element of N
d. 2 is an element of N.

d istrue

Choose the correct answer.
4.W= {0,1,2,3,..}Name the subset of this.
there can be many {1,2}
5.A= {1,2,3,4}
B=(1,2,3,4,5,6,7,8,9,)
is A equal to B
no

6.Name the subset for (1,3,5,7,9...}
there cn be many {3,5,7}
7.A=(a,b,c), B=(c,d,e)
Then what is the intersection of A & B is
it is (c)

Answer 2

1. If A= (2,4,5), B= (1,2,4,7) then what represent A.?

it represents a vector in 3 dimensional space,
it could also represent a point.

2.which of these sets are infinite?
a. (0,2,4,..),b. (...,-4,-2,0), c.(0), (20,22,24..)
a and b

3. If N=(1,2,3,..) then
a. (-2 is a element of N)
false
b. 15 is not a element of N
true
c. 1/3 is an element of N
false
d. 2 is an element of N.
true


Choose the correct answer.
4.W= {0,1,2,3,..}Name the subset of this.
5.A= {1,2,3,4}
B=(1,2,3,4,5,6,7,8,9,)
is A equal to B
No, A is a subset of B

6.Name the subset for (1,3,5,7,9...}
7.A=(a,b,c), B=(c,d,e)
Then what is the intersection of A & B is?
A ∩ B ={c} .
