The correct option is B.
Pan balance is one of the instruments that are used to measure weights of objects. The instrument is designed in such a way that, it has two pans and a standard weight can be added to one of the pan to determine the weight of the object in the other pan. In the question given above, the pan balance is to be used to measure the weight of a large rock. Salt is the right object to be used on the second pan because it can be packaged in standard weights and it is very light in weight. So, it will be very sensitive to the weight of the rock that is been added on the other pan.

Answer:

96

Step-by-step explanation:

The average for the first 6 days was 100, and it ended up dropping overall by 2 for the average.

6 days=x/6=100

4 days=x/4=98/100

You can do 96+100/2 which is 98 degrees.

Hello from MrBillDoesMath!

Answer:s:

For #18, see attachment, "Scatterplot_18", where the data is plotted. It looks like choice J -- no association-- is the correct answer.

For #14 it looks like you had some confusion but are on the right track. The formula for compound interest is  Amount = P(1+r)^n, where P if the Principal (initial investment), r is the yearly rate, and "n" is the number of years invested. In your case,

A = 1000 ( 1 + .02)^3                 =>  as 2% = 2/100 = .02; n = 3 as money

                                                         invested for three years

A = 1000 (1.061208) =

      $1061.21

This is the same answer you got but is NOT one of the choices. Hmmm.....

Thank you,

MrB
