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.

answer: the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

step-by-step explanation:

the given rate of interest i= 85%

in calculating the monthly payment for a loan with an interest rate compounded monthly, the value of the interest rate per period we use in the formula must be in decimal form.

to convert it in decimal, we divide it by 100, we get

hence, the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

27/4x^6 y^8

step-by-step explanation:

4(3x^2y^4)^3 (2x^3y^5)^4

=

108x^6 y^12 /16x^12 y^20

=

108 /16x^6 y^8

=

27 /4x^6 y^8
