What is the cardinality of the set of even positive integers less than or equal to 10?

What is the cardinality of the set of odd positive integers less than 10? Explanation: Set S of odd positive an odd integer less than 10 is {1, 3, 5, 7, 9}. Then, Cardinality of set S = |S| which is 5.

What are all the positive integers less than 10?

There are 9 positive integers less than 10 which are 1, 2, 3, 4, 5, 6, 7, 8, and 9.

What are the positive integers whose square are less than 30?

Clearly, from the limited list, only 1, 2, 3, 4, 5 (and 0) have squares less than 30. 4. Since all other positive integers are larger, and “taking squares” in a monotonously increasing function, those must be the only positive integers whose squares are less than 30.

What are the four negative integers greater than 30?

-1,-2,-29,-24 is four negative integers greater than -30.

What are the composite numbers less than 30?

Answer: 20 ,21 ,22, 8 ,9 ,10, 14 ,15 ,16 are consecutive composite numbers less than 30.

Which number is less than 30?

What is the sum of first 20 positive integers?

Answer: The sum of first 20 positive integers will be 210.

What is the universal set of all non-negative even numbers?

If your universal set is , then is the set of all non-negative even number union the set of all integers greater than 19. So it’s important to specify your universal set since will be different if the former is different.

How to prove that a(n) holds for all positive integers n?

Let A(n) be an assertion concerning the integer n. If we want to show that A(n) holds for all positive integer n, we can proceed as follows: Induction basis: Show that the assertion A(1) holds. Induction step: For all positive integers n, show that A(n) implies A(n+1). 3 Standard Example

What is the Count of valid numbers when n = 10?

When N < 10 then the count of valid numbers will be N. When N / 10 < 10 then 9. When N / 100 < 10 then 9 + N – 99. When N / 1000 < 10 then 9 + 900. When N / 10000 < 10 then 909 + N – 9999.
