The four numbers (assuming they are integers) are 7, 9, 11, and 13. An easy way to find these numbers in your head is that 11 + 9 = 20, and 7 + 13 = 20, and 20 + 20 = 40. Thus, 9 is the second number in the sequence. 4 Numbers. It means you will find their mean value by dividing 40 by 4 which is 10.
What are two prime numbers that equals 40?
This observation has been studied a great deal, and has led to the following theorem:
- Let π (x) be a prime-counting function that gives the number of prime numbers at or below a particular real number x.
- Let ln (x) denote the natural logarithm of x.
- The Prime Number Theorem asserts this limit: (2)
- The limit in equation (2), known as the asymptotic law of distribution of prime numbers, can be restated as an approximation: (3)
What numbers can go into 40 evenly?
The next prime number you have to take into consideration is 3. 45 divided by 3 equals 15, which means it divided evenly. c) Further on we have to see how to determine the prime number for 15 since it is not a prime number.

What is a combination?
A combination is a way to select a part of a collection, or a set of things in which the order does not matter and it is exactly these cases in which our combination calculator can help you.
How to calculate combinations?
There are two formulas for calculating the number of possible combinations in an "n choose k" a.k.a. "n choose r" scenario, depending on whether repetition of the chosen elements is allowed or not. In both equations "!" denotes the factorial operation: multiplying the sequence of integers from 1 up to that number.
Combinations with repetition
In some cases, repetition of the same element is desired in the combinations.
N choose K problems with solutions
Often encountered problems in combinatorics involve choosing k elements from a set of n, or the so-called "n choose k" problems, also known as "n choose r". Here we will examine a few and work through their solutions. These can all be verified using our ncr formula calculator above.
N choose K table
Here is a table with solutions to commonly encountered combination problems known as n choose k or n choose r, depending on the notation used. Solutions are provided both with and without repetition.
Combinations vs permutations
The difference between combinations and permutations is that while when counting combinations we do not care about the order of the things we combine with permutations the order matters. Permutations are for ordered lists, while combinations are for unordered groups.
What is 40 in binary?
40 in binary is 101000. Unlike the decimal number system where we use the digits 0 to 9 to represent a number, in a binary system, we use only 2 digits that are 0 and 1 (bits). We have used 6 bits to represent 40 in binary. In this article, we will show how to convert the decimal number 40 to binary.
How to write 40 as a decimal?
Step 1: Divide 40 by 2. Use the integer quotient obtained in this step as the dividend for the next step. Repeat the process until the quotient becomes 0. Step 2: Write the remainder from bottom to top i.e. in the reverse chronological order. This will give the binary equivalent of 40. Therefore, the binary equivalent of decimal number 40 is 101000.
What is the process of long addition with decimals?
The process for long addition with decimals is the same as the process of long addition of whole numbers with the added column for decimal places. Just as place values are stacked in the same column, all decimal points are stacked in the same column.
How to add whole numbers?
Adding Whole Numbers by Long Addition 1 Stack your numbers and align the columns by place value. 2 Add all numbers column by column from right to left. 3 Record the sum in the answer space for each column. 4 If the sum of any one column is greater than nine, carry the additional digits to the next highest column.
