What set of numbers does 0.25 belong?
To any set that contains it! It belongs to {0.25}, or {45, sqrt(2), pi, -3/7, 0.25}, or multiples of 0.05, or fractions between 0 and 1, or reciprocals, or rational numbers, or real numbers, or complex numbers, etc.
What set of numbers does 45 belong to?
To any set that contains it! It belongs to {45}, or {45, sqrt(2), pi, -3/7}, or all whole numbers between 43 and 53, or multiples of 5, or composite numbers, or counting numbers, or integers, or rational numbers, or real numbers, or complex numbers, etc.
Which set of numbers does -3.5 belong to?
To any set that contains it! It belongs to {-3.5}, or {-3.5, sqrt(2), pi, -3/7}, or all numbers between -43 and 53, or multiples of 0.5, or rational numbers, or real numbers, or square roots of 12.25, or complex numbers, etc.
How many 3 digit numbers are multiples of 5?
99
What is range and mean of a set of numbers?
The mean is the average of the set of numbers. To find it you have to add up all of the numbers in the set and divide by however many numbers there are in the set. For example, if you had the set: 1, 2, 3, then you would add them up to get 6. Since there are 3 numbers you would divide by 3 to get 2. The range is the highest number in the set minus the lowest number in the set. Example: of you have the set: 1, 2, 3, 4, 5, 6, 7, 8, then the range would be 8-1, or 7.
Which number can divided by 3 without leaving a remainder?
The infinite set of numbers which are multiples of three. The infinite set of numbers which are multiples of three. The infinite set of numbers which are multiples of three. The infinite set of numbers which are multiples of three.
Which set consists of numbers that are multiples of both 3 and 4?
The set of multiples of 12.
What is closed under subtraction?
The set of all integers; the set of all rational numbers; the set of all real numbers; the set of all complex numbers. Also their multiples - for example the set of all multiples of 2; the set of all multiples of 2.5; the set of all multiples of sqrt(17); the set of all multiples of 3 + 4i where i is the imaginary square root of -1.
What are multiples of 3's?
The multiples of 3 are elements of the infinite set of numbers of the form 3*k where k is an integer.
What are the common multiples of 12 and 3?
The common multiples of 3 and 12 are the infinite set of numbers that are multiples of 12, which is the least common multiple of 3 and 12. The set is 12, 24, 48, 60, 72, 84, 96, 108, 120, 132, 144, 156, 168, 180, and so on.
What is the set of even numbers?
The set of even numbers is the set of all the numbers that are divisible by 2 (or multiples of 2).
What number are both multiples of 3 and 4?
They are members of the infinite set of numbers of the form 12*k where k is an integer. Since the set is infinite, it is not possible to list them.
Why is the prime factorization of 180 2x2x3x3x5?
2, 3, and 5 are all prime numbers and that is the only set of prime numbers that multiples to 180.
Which set of numbers does 4 go into?
Itself and its multiples
What is the set of odd numbers that are multiples of 10?
That's a null set. All multiples of 10 are even.
How many numbers between 10 to 50 are multiples of 3 and 5?
There are three numbers between 10 and 50 which are divisible by both 3 and 5. All numbers that are multiples of 3 and 5 are the multiples of the lowest common multiples (lcm) of 3 and 5 which is 15. The multiples of 15 between 10 and 50 are {15, 30 and 45}, thus there are 3 numbers.
How do you identify the first three common multiples of a set of numbers?
Find the LCM. Multiply it by 2. Multiply it by 3.
