Express the following relations in the set builder notation. Then, determine whether it is reflexive, symmetric, transitive. Ple

pshichka [43]

Answer:

a)Reflexive, not symmetric, transitive

b)Reflexive, not symmetric, transitive

c)Not reflexive, symmetric, not transitive

d)Reflexive, not symmetric, transitive

Step-by-step explanation:

a)

$R=\left \{ (a,b)\epsilon \mathbb{R} \times \mathbb{R} \mid a \leq b\right \}$

The relation R is reflexive for

$a\leq a$ for every real number a

it is not symmetric because 0 is less than 1, but 1 is not less than 0

it is transitive

$a\leq$ and $b\leq c\Rightarrow a\leq c$

So if aRb and bRc, then aRc

b)

$R=\left \{ (m,n)\epsilon \mathbb{Z} \times \mathbb{Z} \mid \exists k\in \mathbb{Z} \ni m=kn \right \}$

R is reflexive because m=1.m for every integer m

R is not symmetric: 2 is a factor of 4, but 4 is not a factor of 2

R is transitive: if mRn and nRp if m=kn and n=qp, so m=(kq)p and kq is an integer , so mRp

c)

$R=\left \{ (m,n)\epsilon \mathbb{Z} \times \mathbb{Z} \mid m\neq n\right \}$

R is obviously not reflexive because all numbers equals themselves

R is symmetric: if a different to b, then b different to a

R is not transitive: 1R2 and 2R1 (because 1 different to 2), but 1 = 1

d)

$R=\left \{ A,B\mid A\subseteq B \right \}$

R is reflexive for every set A is a subset of itself

R is not symmetric {1,2} is a subset of {1,2,3} but {1,2,3} is not a subset of {1,2}

R is transitive: if A is subset of B and B is subset of C, then A is subset of C

Notebooks are priced 3.20 for 4 notebooks Pencils are priced 4.80 for 12 pencils, write a rate

olga55 [171]

Answer:

$0.80 per notebook

$0.40 per pencil

Step-by-step explanation:

To find the rate, we need to determine how much each item costs. That is, the cost per item.

Given that,

4 notebooks = $3.20

The cost of 1 notebook/rate = $\frac{3.20}{4} = 0.80$

Rate = $0.80 per notebook

Given that,

12 pencils = $4.80

The cost of 1 notebook/rate = $\frac{4.80}{12} = 0.40$

Rate = $0.40 per pencil.
