The table shows the weights of 3 samples from an experiment.

which estimate is reasonable for the total weight of all 3 samples?

1.25 g

3.75 g

5.5 g

6.5 g

sample number weight (g)
1 1.25050
2 2.50055
3 2.74099

The estimate reasonable for the total weight of the three samples is:

                  6.5 g.

Step-by-step explanation:

The table is given as follows:

Sample NumberWeight (g)

         1                 1.25050

         2                 2.50055

         3                 2.74099

Now, we write the approximate value of the weights of each of the samples up to two decimals places as:

Sample NumberWeight (g)

         1                 1.25

         2                 2.50

         3                 2.74

   Total                  6.49

which is approximately written as:

6.5 g.
