Does integers contain the number zero?
Yes
Why zero is not a natural number?
Zero is not a natural number because the definition of a natural number is the set of positive integers that does not contain zero.
How many 4 digit numbers can you make that contain 5?
There is a clever but tricky way to solve this. If we have to find the number of 4-digit integers that contains at least one 5, we can also find the number of all the 4-digit integers and the number of integers that do not contain any 5's and subtract it from the first number. This is called complementary counting.So, first of all, we must find the number of 4-digit numbers there are. There are 9000 of them.Now, we find the number of 4-digit integers without 5's. By thinking a little bit, we see the first digit must be from 0~9 excluding 5. That is a total of 9 numbers. This is the same for the next three digits. Therefore, there are 94 = 6561 4-digit numbers without a 5.Finally, we can subtract. 9000 - 6561 = 2439
Why is 0.8 recurring a rational number?
It can be expressed as the ratio of two integers: 8/9.
What is the number of positive integers less than 6000 which are divisible by 5 but not by 9?
533
What are all the numbers sets that contain the number -8?
integers and rational numbers
Is 45 a triangular number?
Yes, sum of integers 1 - 9.
What are the definitions of integers?
Integers are whole numbers that do not contain fractions or decimals
Square of a rational number is rational?
Sure. Let's take an example with numbers instead of variables. 8/9 is a rational number - the ratio of two integers. If you square it, you get (8/9)2 = 82/92 = 64/81; that is, if you square each integer, you get an integer again. Therefore, the resulting number is rational again - a number that can be expressed as the ratio of two integers. Replace with any other integers; you will still have a ratio of integers if you square it.
Is -9 a whole number?
No. Whole numbers are zero and positive integers. (0,1,2,3,4) -9 is an example of negative integer.
How do you find the mean of positive and negative integers?
you add up the integers and then divide by the number of numbers there are.Example: -8, -1, 9, 16 -There are four numbersAdd -8 + -1= -9+9=0+16= 16Divide by number of numbers 16 divided by 4= 44 is the mean
The ratio of two positive integers is 7 to 9 One number is 4 more than the other What are the two integers?
the two numbers are 14 and 18
Integers find the difference 9 - 26?
-17
Is 3 a square root number?
All integers are square roots. 3 is the square root of 9.
Is the number 0.7777... repeating forever rational or irrational?
0.777.... = 7/9 which is the ratio of two integers, therefore 0.777... is a rational number.
What is the least common number of 4 and 9?
The least common multiple of any set of positive integers is 1.
The sum of two consecutive integers is -9 what are the integers?
-4 and -5
