Completing the given sentence with the most appropriate,

striving the best of both worlds, is a very risky bet

Striving the best of both worlds is a very risky task.

This is the correct form of the sentence given.

In the given statement, we are not making any bet. But striving for the best is an option and not a compulsion.

Therefore, "task" is a better fit for the sentence than "bet".

Answer:

If you take with the standard topology any finite set is closed as it is the complement of an open set. The open intervals form a basis for the standard topology. The complement of a finite set is precisely the union of open sets.

If it helps mark as Brainliest answer

Each finite set is closed set

Explanation:

• Thinking A as a subset of metric space M.
• An easy approach will be to use that the single points [tex]{X_{j}}\subset M[/tex] are closed, then of course[tex]A=Union\hspace{0.2 cm}of\hspace{0.2 cm} X_{j}[/tex]

• from j=1 to j=n.

• Since A is a finite union of closed set, it is itself closed.

Also, If we show that the complement of A is open, then A is closed.

• Let [tex]B=A^{c}[/tex], and suppose that y∈B. We need to show that there is an r>0 for which Br(y)∩A=∅, that is Br(y)⊂B.

• If we let r=min{d(y,xi) : i=1,...,n} then it must be true that Br(y)∩A=∅, since for every z∈Br(y) we have d(z,y)<d(y,xi) for each i=1,...,n.

• This clearly shows that the complement of A is open which means A should be closed.

Hence, Every finite set is a closed set.

Answer:

Let the fourth proportional to 4, 9, 12 be x

Then, 4:9::12:x

⇒4×x=9×12

⇒x=

4

9×12

=27

∴ Fourth proportional to 4, 9, 12 is 27.
