Why is the absolute value of a non zero number positive?
i didnt get this answer.sorry
A number is chosen at random from the first 20 positive whole numbers What is the probability that it is not a prime number?
There are 12 composite (and 8 primes) in the first twenty whole numbers. So the probability of randomly choosing a non-prime is 12/20 or 60%.
Are all whole numbers positive numbers?
Yes, EXCEPT for the number 0. It is a whole number but is not positive or negative. Real Numbers - Everything I. Rational Numbers- Any number except for non terminating decimals A. Integers- Any negative or positive number...not a decimal1. Whole Numbers- Any positive integer INCLUDING ZEROa. Natural Numbers- Any positive integer (NOT INCLUDING ZERO) The answer is not entirely correct, Whole numbers are numbers without a fractional part or decimal point. Therefore whole numbers can be negative as well as positive. -2 is a whole number but is not positive. There are a number of different interpretations for whole numbers, from non-negative integers, positive integers and all integers (which includes negative integers)
What numbers always have an even number of factors?
All positive integers which are not perfect squares.
What are non positive integers?
Non-positive integers are zero and the negative integers.
