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.

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2

the terms of a geometric sequence can be found by beginning with the first term and multiplying by the common ratio repeatedly. a recursive formula for a geometric sequence with common ratio r is given by an=ran−1 a n = r a n − 1 for n≥2 n ≥ 2 .
