Question

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

Answer 1

Answer:

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 Number Weight (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 Number Weight (g)

         1                 1.25

         2                 2.50

         3                 2.74

   Total                  6.49

which is approximately written as:

6.5 g.

Answer 2

6.5 grams, it is the closest
