There are an infinite number of sets-of-4 that all have a mean of 12.
Here are a few of them :
12, 12, 12, and 12
10, 11, 12, and 15
5, 10, 15, and 18
5, 7, 13, and 23
-12, 10, 20, and 30
1, 2, 3, and 42

Well, if you really mean divisible by 4 then the answer is 100% that is probability 1.00. On the other hand, if you mean evenly divisible by 4, then in the numbers 1-12 there are 3 numbers evenly divisible by 4 (4, 8, 12) since there are 12 numbers then the probaqbility of a number divisible by 4 is 3/12 = 0.25
Their geometric mean is the cube root of 8*4*12 = cuberoot(384) = 7.268 (to 3 dp)
Mean = 4 so sum = 4*4 = 16 The sum of the three numbers is 12 so the fourth is 16-12 = 4.
the mean of those numbers is 7
To fnd the mean you add all the numbers and then divide by the amount of number you added. e.g. The mean of 2, 4, 6 = 4 2+4+6=12 12/3=4

Well, if you really mean divisible by 4 then the answer is 100% that is probability 1.00. On the other hand, if you mean evenly divisible by 4, then in the numbers 1-12 there are 3 numbers evenly divisible by 4 (4, 8, 12) since there are 12 numbers then the probaqbility of a number divisible by 4 is 3/12 = 0.25
you have to add all the numbers together and divide by the number of dat/numbers there are e.g mean of: 6, 2 , 4 1) 6 + 2 + 4 = 12 2) 12 divided 3 = 4
Their geometric mean is the cube root of 8*4*12 = cuberoot(384) = 7.268 (to 3 dp)
to solve the mean, you add up all the numbers. then you divide it by the amount of numbers there are.ex. 2, 4, 6= 12 divided by 3= 4
Mean = 4 so sum = 4*4 = 16 The sum of the three numbers is 12 so the fourth is 16-12 = 4.
All numbers have factors. Some factors are prime numbers, some are composite numbers, one is neither. The factors of 12 are 1, 2, 3, 4, 6, 12 Since 4, 6 and 12 are composite numbers, they are the composite factors of 12.
Add the 4 numbers together and divide by 4, the answer is 17.
All numbers have multiples. Some numbers have some of the same multiples as other numbers. These are known as common multiples. 12 is a multiple of 3 12 is a multiple of 4 12 is a common multiple of 3 and 4
