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


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

A1.25 g

B3.75 g

C5.5 g

D6.5 g

Sample Number Weight (g)


1 1.25050


2 2.50055


3 2.74099

Verified Answer :

I got 6.49204 but you will need to round so D 6.5

I added all of the numbers up

Answer: D. 6.5 g


Step-by-step explanation:

From the given table , weight of sample 1 = 1.25050 g

Weight of sample 2 = 2.50055 g

Weight of sample 1 =  2.74099 g

The total weight of all the 3 samples= \(1.25050\ g+2.50055\ g+2.74099\ g\)

Therefore, the total weight of all the 3 samples= \(6.49204\ g\)

Since, \(6.49204\approx6.5\)

Thus, the estimated total weight of all 3 samples= 6.5 g
