A chemical engineer must report the average volume of certain pollutant produced by the plants under her supervision here are the data she has been given
Lincoln 6.824L
Oglala 5.8L
South fork 13.3L
What average volume should the chemical engineer report? Be sure your answer has the correct number of significant digits in L?
To find the average volume, we must add up all the given volumes and then divide by the number of plants considered.
Total volume = 6.824L + 5.8L + 13.3L = 25.924L
Since we have three plants, divide the total volume by three:
Average volume = 25.924L / 3 = 8.641L
The correct number of significant digits should match the least precise measurement given, which is 5.8L (2 significant digits). Therefore, the average volume should be reported as 8.6L.
To find the average volume of the pollutant produced by the plants, we add up the volumes and divide by the number of plants.
Adding up the volumes: 6.824L + 5.8L + 13.3L = 25.924L
Dividing by the number of plants (which is 3 in this case): 25.924L / 3 = 8.641L
Since the data provided has only one significant digit after the decimal point, the average volume should be reported as 8.6L.
