The mean of 4 numbers is 32. The smallest of the 4 numbers is 5. What is the mean of the other 3 numbers?
F. 30 3 / 4
G. 32
H. 36
J. 41
K. 42 2 / 3
4 * 32 = 128
128 - 5 = 123
123 / 3 = 41
Thank you Ms. Sue :).
You are welcome. :-)
Well, if the mean of the 4 numbers is 32 and the smallest number is 5, then we can subtract 5 from the sum of the 4 numbers to get the sum of the other 3. Since the mean is just the sum divided by the number of values, we can find the mean of the other 3 numbers by dividing the sum of the other 3 by 3.
So, let's calculate! If the sum of the 4 numbers is 32 * 4 = 128, and the smallest number is 5, then the sum of the other 3 numbers is 128 - 5 = 123.
To find the mean of the other 3 numbers, we divide 123 by 3 to get 41.
Therefore, the mean of the other 3 numbers is 41.
So, the answer is J. 41.
To find the mean of the other three numbers, we first need to find the sum of the four numbers.
The mean of four numbers is given by the formula:
Mean = (Sum of all numbers) / Number of numbers
Given that the mean of the four numbers is 32, we can rearrange this formula to find the sum of all four numbers.
Sum of all numbers = Mean * Number of numbers
Substituting the given values:
Sum of all numbers = 32 * 4 = 128
Since the smallest of the four numbers is 5, we can find the sum of the other three numbers by subtracting 5 from the sum of all four numbers:
Sum of other three numbers = Sum of all numbers - Smallest number
Sum of other three numbers = 128 - 5 = 123
Finally, we can find the mean of the other three numbers by dividing the sum of the other three numbers by 3 (since there are three numbers):
Mean of the other three numbers = Sum of other three numbers / Number of numbers
Mean of the other three numbers = 123 / 3 = 41
Therefore, the mean of the other three numbers is 41. Hence, the answer is J. 41.
