Let A be the set of all lines in the plane. Define a relation R on A as follows. For every l1 and l2 in A, l1 R l2 ⇔ l1 is paral
Lyrx [107]

Answer:

Hence, the relation R is a reflexive, symmetric and transitive relation.

Given :

A be the set of all lines in the plane and R is a relation on set A.

R=\{l_1,l_2\in A|l_1 \;\text{is parallel to}\; l_2\}

To find :

Which type of relation R on set A.

Explanation :

A relation R on a set A is called reflexive relation if every a\in A then (a,a)\in R.

So, the relation R is a reflexive relation because a line always parallels to itself.

A relation R on a set A is called Symmetric relation if (a,b)\in R then (b,a)\in R for all a,b\in A.

So, the relation R is a symmetric relation because if a line l_1 is parallel to the line l_2 the always the line l_2 is parallel to the line l_1.

A relation R on a set A is called transitive relation if (a,b)\in R and (b,c)\in R then (a,c)\in R for all a,b,c\in A.

So, the relation R is a transitive relation because if a line l_1 s parallel to the line l_2 and the line l_2 is parallel to the line l_3 then the always line l_1 is parallel to the line l_3.

Therefore the relation R is a reflexive, symmetric and transitive relation.

Nadusha1986 [10]

Answer:

f(g(x)) = 4x² - 12x + 9

Step-by-step explanation:

Substitute x = g(x) into f(x) , that is

f(g(x))

= f(2x - 3)

= (2x - 3)² ← expand using FOIL

= 4x² - 12x + 9

As part of a research project on student debt at TWU, a researcher interviewed a sample of 35 students that were chosen at rando
Inga [223]

Answer:

Option a is right

Step-by-step explanation:

Given that as part of a research project on student debt at TWU, a researcher interviewed a sample of 35 students that were chosen at random concerning their monthly credit card balance.

Sample average = 2573

Variance = 4252

Sample size = 35

STd deviation of X = \sqrt{4252} \\=65.21

Score of student selected at random X=1700

Corresponding Z score = \frac{1700-2573}{65.201} \\=-13.38

Rounding of we get Z score = -13.4

option a is right
