(c) How many significant figures are there in the value 0.00470 centimeters? (d) The mass of a rock sample is measured four times, yielding values of 24.996 grams, 25.008 grams, 25.011 grams, and 25.005 grams. What is the average mass of the sample in units of grams? The average value is determined by taking the sum of all samples and dividing by the total number of samples.

this is 100% correct, but please tell me how to solve this carefully.

using the sine bar technique, find the value of the angle for the given data: the stacked height was composed of the following values, 30, 20, 5, 2 and 1.1 mm. The length of the sine bar is 150 mm. Support your answer by sketch.

Hi please help with this question thank you I just can't seem to work it out even with the given formulas. Thanks! also, I have tried these but they seem to be incorrect, or maybe parts of the calculation may be incorrect since when I submit these all together and I can't really work out where I am going wrong: sigma x = 25.43 sigma y = 13.07 Txy = 49.124

Kindly include the solution and units used please. Thanks

As an exercise, a student weighed several bunches of nails on a balance. The nails were not all the same size. Here are the student's data: 4. number of nails mass in grams 82 122 208 324 435 12 20 26 Prepare a plot of these data on the grid below or on the graph paper. Use "number of nails" as the independent variable and be certain to scale and label the axes correctly. Scale the axes starting at the origin; 0, 0. GO 20 向 12 円 Number of nails Cx) 2. 18 20 mass in
