Question

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

Answer 1

6.5 grams, it is the closest

Answer 2

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

6.5 g.

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.
