Is the number 14 a abundant perfect or deficient number?
14 is deficient. It is less than the sum of it's divisors. In mathematics, a deficient number or defective number is a number n for which σ(n) < 2n. Here σ(n) is the sum-of-divisors function: the sum of all positive divisors of n, including n itself Proof.. divisors of 14 are 1,2, and 7 and 14. Now, 2n=28 and and the sum the all the divisors including 14 is 24<28
What is the set of numbers that includes all rational and all irrational numbers?
the set of real numbers
Find the domain and range fx3x-2?
the domain is all real numbers and the range is all real numbers the domain is all real numbers and the range is all real numbers
Is the number 21 abundant or deficient or perfect?
It is deficient: It's only proper divisors are 1, 3, and 7, which sums to 11, which is less than 21.
How do you get the mode when there all different numbers?
There is no mode if all of the numbers are different.
Is any prime number have to be deficient?
All prime numbers are deficient.
Are all prime numbers deficient?
Yes.
Are there more deficient numbers than abundant and perfect numbers?
There are more deficient numbers.
List all deficient numbers up to 100?
1,2,3,4,5,7,8,9,10,11,13,14,15,16,17,19,21,21,23,25,26,27,29,31,32,33,34,35,37,38,39,41,43,44,45,46,47,49,50,51,52,53,55,57,58,59,61
Is number 11 an abundant and why?
No. All prime numbers are deficient.
Is 63 a deficient number?
All odd numbers with one or two distinct prime factors are deficient. Since 3 and 7 are factors of 63, it must be deficient.
Are all deficient numbers odd numbers?
no, 945 is the first abundant odd number though

Yes, like all prime numbers.
Is the number 47 a dificient number?
Yes. All prime numbers are deficient.
Is it possible for a prime number to be a perfect number and why?
No, all prime numbers are deficient.
Is the number 17 a Deficient number?
17 is a deficient number because half the sum its factors is less than 17 [(1 + 17)/2 = 9)]. All odd numbers less than 945 are deficient.
