How do you find the mean of positive and negative integers?
you add up the integers and then divide by the number of numbers there are.Example: -8, -1, 9, 16 -There are four numbersAdd -8 + -1= -9+9=0+16= 16Divide by number of numbers 16 divided by 4= 44 is the mean
What is the fifth number if there is a sum of four numbers that equal 40 when there is a fifth number added and the mean of the numbers become 12what is the fifth number?
The sum of four numbers equals 40: a+b+c+d=40 Those same four numbers, along with another number (e), give the set a mean of 12: (a+b+c+d+e)/5=12 Use these two facts to determine e as follows: (a+b+c+d+e)/5=12 a+b+c+d+e=60 (a+b+c+d)+e=60 40+e=60 e=20
An is the number found by dividing the sum of numbers by the number of addends?
That is an average or the mean.
The mean of three numbers is 7 if two of the numbers are 5 and 20 then what is the third number?
-4
What is the smallest negative perfect square that is divisible by the four smallest prime numbers?
Perfect squares are positive. A smallest negative number doesn't exist. The four smallest prime numbers are 2, 3, 5 and 7. The smallest perfect square would have to be 2^2 x 3^2 x 5^2 x 7^2 or 44,100
The mean of four numbers is 25 and three of the numbers are 17 23 and 25 what is the fourth number?
the mean of four numbers is 25 and three of the numbers are 17 23 and 25 what is the fourth number?
The mean of four numbers is 30. If three of the numbers are 12 50 and 48 what is the fourth number?
The fourth number is 10. The sum of the four numbers is: 12 + 50 + 48 + fourth_number = fourth_number + 110 Mean = sum_of_numbers / how_many_numbers → sum_of_numbers = mean × how_many_numbers = 30 × 4 = 120 But from above: sum = fourth_number + 110 = 120 → fourth_number = 120 - 110 = 10
How do you find the average of four numbers when the fourth is unknown?
If that is what you mean, then you have 3 numbers, not 4, and you can't find an average when the unknown number could be any number. Basically, you have one equation with 2 unknowns and that can't be solved.
How do you work out the median for a set of eight numbers?
Arrange the numbers in ascending order, and then take the mean of the fourth and fifth number.
What does it mean that answer correct to 4 decimal places?
It means to round the number to the nearest four decimal places (0.0000) for example the number 12.3476589 would be 12.3477 . The four decimal places are the amount of numbers after the decimal dot. For the fourth number after the decimal point, if the number after it is 5 or higher, than you round up to the next decimal number. If it is below five, you leave it as it is. If the fourth number is nine and the next one is eight for example, you also rise the third number as well as the fourth.
What does four digits numbers mean?
1234, 2637, 7777, 2727 are examples of a four digit number. So any random four numbers are four digits.
The mean of 4 numbers is 88The sum of 3 of the numbers is 80 what is the fourth number?
Let the fourth number be x. We have: (80 + x)/4 = 88 (multiply both sides by 4) 80 + x = 352 (subtract 88 to both sides) x = 272 Thus, the fourth number is 272.
The mean of 4 consecutive numbers is 9.5 What is the fourth number?
Suppose the four numbers are x, x+1, x+2 and x+3 Then their sum is 4x + 6 so that their mean is (4x+6)/4 = x + 6/4 = x+1.5 So x+1.5 = 9.5 so that x=8 and so the largest number is x+3 = 8+3 = 11. This answer assumes that the 4 consecutive numbers are in increasing order. If they were four consecutive numbers in decreasing order, they would be x, x-1, x-2 and x-3. In this case x=11 and the fourth number would be 8.
what is the fourth number if the three numbers are 80,95, and 85 if the mean is 88?
The three numbers are 80,95,85 Let the fourth number be x. Now the mean is 88 That is (80+95+85+x) /4=88 i. e. 260+x=88×4 i. e. 260+x=352 i. e. x=352-260=92 So fourth number is 92.
What does the prefix quat mean?
The prefix "quat" typically signifies the number four or a fourth part. It is often used in words related to quantity, such as "quadrant" (a fourth part of a circle) or "quartet" (a group of four musicians).
The mean of 5 number is 27 Four of the numbers are 24 33 27 and 31 What is the fifth number?
20
What does in a power the number used as a factor mean?
Numbers with exponents are sometimes referred to as a power. For example, x^4 can be called "x to the fourth power" which means that x is used as a factor four times. So, in a power, the number used as a factor is the base.
