how do you estimate a range for the sum of 9.6+3.1+5.8
well I suppose it could be
9.65 + 3.15 + 5.85
or it could be
9.55 + 3.05 + 5.75
note I call 4.35= 4.4 and 4.34 = 4.3
To estimate a range for the sum of 9.6 + 3.1 + 5.8, you need to determine the minimum and maximum possible values for each number and then add them together.
The minimum value for 9.6 is 9.6 itself.
The minimum value for 3.1 is 3.1.
The minimum value for 5.8 is 5.8.
Therefore, the minimum possible sum is 9.6 + 3.1 + 5.8 = 18.5.
The maximum value for 9.6 occurs when the value is rounded up to 10.0.
The maximum value for 3.1 occurs when the value is rounded up to 4.0.
The maximum value for 5.8 occurs when the value is rounded up to 6.0.
Therefore, the maximum possible sum is 10.0 + 4.0 + 6.0 = 20.0.
Hence, the estimated range for the sum of 9.6 + 3.1 + 5.8 is 18.5 to 20.0.
To estimate a range for the sum of 9.6+3.1+5.8, we can use a method called interval estimation. This involves finding the minimum and maximum possible values for each number, and then adding up the minimum values and the maximum values separately.
Step 1: Find the minimum possible values for each number:
The minimum value for 9.6 is 9.6 itself.
The minimum value for 3.1 is 3.1 itself.
The minimum value for 5.8 is 5.8 itself.
Step 2: Find the maximum possible values for each number:
The maximum value for 9.6 is 9.6 itself.
The maximum value for 3.1 is 3.1 itself.
The maximum value for 5.8 is 5.8 itself.
Step 3: Calculate the sum of the minimum values:
Minimum sum = 9.6 + 3.1 + 5.8
Step 4: Calculate the sum of the maximum values:
Maximum sum = 9.6 + 3.1 + 5.8
By performing these steps, we can determine the range for the sum of 9.6+3.1+5.8.
