the mean of four numbers is 25 and three of the numbers are 17 23 and 25 what is the fourth number?
The mean times three will be the total of all three numbers. Multiply the mean times three and subtract the sum of the two numbers from that total.
Any numbers that are equivalent to 21.
The first three prime numbers are 2, 3, 5. To find the mean, add them up, and divide this sum by how many numbers (3). So (2 + 3 + 5) /3 = 10/3 or approx 3.33
Mean is the same as average. To get the mean of a set of numbers: First, you add up all the numbers. Second, you divide by the number of numbers in the set. Total of all the numbers/Number of numbers in the set
if you mean what three prime numbers add up to a prime number then the answer is : 5 + 7 + 11 = 23
If you mean "the sum of three odd numbers", that isn't possible. The sum of three odd numbers will always be an odd number.
The mean number from a set of numbers is the average.Example: (5 + 6 + 7) ÷ 3 = 6 (therefore the average of the three numbers is 6).
You divide by the number of numbers - if you want the mean of three numbers you divide by 3, if you want the mean of a hundred numbers you divide by 100.
The mean of numbers is the average. To find this, first add all the numbers, then divide by how many numbers you added.
if you mean the three numbers immediately following 1, its 2, 3, and 4.if you mean any three numbers after 1, then...its any three number you choose.There are no numbers after 1 if you want to get technical. Unless you say 1.000, then the three numbers after 1 would be 0's. But 1 alone, there are none.
because in a mean for 7 with three numbers the total of the 3 numbers must be 21 and (even number) + (even number) = (even number) 21 is odd Q.E.D
I assume you mean the first three "counting" (ordinal) numbers, which are 1, 2, and 3. The sum is therefore 1 + 4 + 9 = 14.
The sum of the first five prime numbers is 28. The sum of the cubes of the first three prime numbers is 160. The average of 28 and 160 is 94.
nothing stupid i mean what a question
The first number is the inches around the chest, the second is around the waist, and the third is around the fullest part of the hips.
Triangluar numbers or triangle numbers are numbers formed from the summation of all the numbers smaller than them. The first few triangle numbers are 1,3,6,10,15,21... If you think of a pyramid with a base of two blocks, and one on top, there are three blocks. If you add a base of three to that pyramid, you have six blocks. Then ten, and fifteen and so on. That is why they are called Triangle numbers.
The first number represents bodily injury per person, the second number represents bodily injury per occurrence, and the last number represents property damage per occurrence. By adding three zeroes to the end of each number, policyholders will have the amount of their coverage. :)
This question is ambiguous. It could mean the numbers 123,456,789 in which case the answer is three as only three combinations of these digits can be used whether or not the 0 is used. Or more likely it could mean the range 100, 101,102,103 etc up to 999 in which case you can work out what the answer is, by subtracting the first number in this range from the last number.
It depends. On a tire sized like a P235/75R15, the 235 is the tread width in millimetres. On a 33-12.50-15 the first number is the height in inches.
They could all be the same number, e.g. 55555 (mean=median=mode=5) or they could be three numbers the same, with an equal space between the first two and the last two, e.g. 24446 (mean=median=mode=4). For the mode to be well-defined, some of the numbers have to be the same.
The first three digits in a phone number represent the area code, which directs the phone call to a specific region according to population density. Lower numbers were typically used for denser areas (because they could be dialed faster on rotary phones), while higher numbers were used for less populated areas.
The mean of a number is the average of a group of numbers. To find the mean you must add up all of the numbers in a data set. Then you take that number and divide it by the number of numbers you have in the data set. This will give you the mean.
If there are only three numbers, the median MUST be the central number. Any question that claims otherwise is incorrect.
