Aman is trapped in a room at the center of a maze. the room has three exits. exit 1 leads outside the maze after 3 minutes, on average. exit 2 will bring him back to the same room after 5 minutes. exit 3 will bring him back to the same room after 7 minutes. assume that every time he makes a choice, he is equally likely to choose any exit. what is the expected time taken by him to leave the maze? hint: let x = time taken by the man to leave the maze from this room. let y = exit he chooses first. so y belongs in {1, 2, 3}. calculate the conditional expectation of time taken to leave the maze given that he chose each of the exits. then use these conditional expectations to calculate the expectation of time taken to leave the maze.

square root

step-by-step explanation:

∠1≅∠2 by the alternate exterior angles theorem.

step-by-step explanation:

given, a ∥ b and ∠1 ≅ ∠3 .we have to prove that e ∥ f

we know that ∠1≅∠3 and that a || b because they are given. we see that by the alternate exterior angles theorem. therefore, ∠2≅∠3 by the transitive property. so, we can conclude that e || f by the converse alternate exterior angles theorem.

we have to fill the missing statement.

transitivity property states that if a = b and b = c, then a = c.

now, given ∠1≅∠3 and by transitivity property ∠2≅∠3 .

hence, to apply transitivity property one angle must be common which is not in result after applying this property which is ∠1.

the only options in which ∠1 is present are ∠1 and ∠2, ∠1 and ∠4

∠1 and ∠4 is not possible ∵ after applying transitivity we didn't get ∠4.

hence, the missing statement is ∠1≅∠2.

so, ∠1≅∠2 by the alternate exterior angles theorem.

the rocket cannot penetrate the ground, in a contextual sense, therefore the roots of this equation should be the domain of this function. i'll let you find the roots of this quadratic equation (hint: use the quadratic formula:  

1- c
