All numbers that only have one and itself as factors are prime. Therefore, to tell if a number is prime simply find it's factors. If it has more than two factors than it is not a prime number.

This question can be written as 30=75% times X75% can be simplified to either 3/4 or .75The fraction makes more sense in my head, because I can easily see that 30 is three-fourths of a certain number. If this makes sense to you, don't bother reading the rest.For the sake of the math sentence, though, I'll do it the decimal way.So we re-write it as 30=.75*Xthen we move the numbers onto one side of the equation and leave the X on the other, by dividing both sides by .75So we're left with 30/.75 = Xwith a calculator, we find that 30 divided by .75 is 40.So X = 40

As it is written, x is the independent variable and y is the dependent. But you could re-write it as x = y/23 + 30/23 and then y is the independent variable and x the dependent.

... then all outcomes are equally likely. Nothing more, nothing less. You can always re-define the outcomes so that they are not all equally likely. For example, on a single roll of a fair die, the numbers 1 to 6 are equally likely. But redefine the events so that Event A = prime number Event B = composite number Event C = neither prime nor composite number then P(A) = 1/2, P(B) = 1/3 and P(C) = 1/6 : events with unequal likelihood.

Each number is either itself a prime number, or it can be separated into smaller prime numbers. A prime number is a number that has no smaller factors. Factorization into prime factors is unique, except for the order of the factors.

A prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1 and 0. 1 and 0 are neither prime, nor composite.

I've seen other variations of this question that ask, "What two numbers have the factors 2, 3 and 5 in common?" The answer to that is 30 and 60, among others. If that's not what you wanted to know, please re-submit the question.

A prime number is a positive whole number (a positive integer) that has exactly two unique positive divisors, 1 and the number itself.
