Let L denote the set of all straight lines in a plane. Let a relation R be defined by $alpha R beta left right double arrow alpha perpendicular beta$ $alpha comma beta element of L. text end text$ Then R is-

So the correct relations are R2 and R3.

If Q= $open curly brackets x colon x equals fraction numerator 1 over denominator y end fraction comma text where end text y element of N close curly brackets comma text end text$ then-

Hence, $1 element of Q$ is correct.

If Q= $open curly brackets x colon x equals fraction numerator 1 over denominator y end fraction comma text where end text y element of N close curly brackets comma text end text$ then-

Hence, $1 element of Q$ is correct.

Let A $equals left curly bracket x colon x element of R comma vertical line x vertical line less than 1 right curly bracket comma B equals left curly bracket x colon x element of R comma vertical line x minus 1 vertical line greater or equal than 1 right curly bracket text end text$ and $A union B$ =R-D, then the set D is

Therefore, set of D is $left curly bracket x colon 1 less or equal than x less than 2 right curly bracket$ .

Let A $equals left curly bracket x colon x element of R comma vertical line x vertical line less than 1 right curly bracket comma B equals left curly bracket x colon x element of R comma vertical line x minus 1 vertical line greater or equal than 1 right curly bracket text end text$ and $A union B$ =R-D, then the set D is

Therefore, set of D is $left curly bracket x colon 1 less or equal than x less than 2 right curly bracket$ .

Therefore, { } is a subset of all givens sets.

Let A and B be two sets such that n(A) = 70, n(B) = 60 and $n left parenthesis A union B right parenthesis$ = 110. Then $n left parenthesis A intersection B right parenthesis$ is equal to-

Therefore, n(A∩B) = 20

Let A and B be two sets such that n(A) = 70, n(B) = 60 and $n left parenthesis A union B right parenthesis$ = 110. Then $n left parenthesis A intersection B right parenthesis$ is equal to-

Therefore, n(A∩B) = 20

Which of the following are true ?

Therefore, from the given options, $left square bracket 3 , 7 right square bracket subset of or equal to left parenthesis 2 , 10 right parenthesis$ is true.

The set of intelligent students in a class is-

Let U = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}, A={1, 2, 5}, B = {6, 7} then $left parenthesis A intersection B right parenthesis to the power of ´ end exponent$ is-

Therefore, A ⋂ B’ = A.

Let U = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}, A={1, 2, 5}, B = {6, 7} then $left parenthesis A intersection B right parenthesis to the power of ´ end exponent$ is-

Therefore, A ⋂ B’ = A.

If $A subset of or equal to B$ , then $A intersection B$ is equal to-

Therefore, $A intersection B$ is equal to = A

If $A subset of or equal to B$ , then $A intersection B$ is equal to-

Therefore, $A intersection B$ is equal to = A

The velocity of a body is given by the equation $v equals 6 minus 0.02 t$ , where t is the time taken. The body is undergoing.
