(1 point) Coal gas is produced at a gasworks. Pollutants in the gas are removed by scrubbers, which become less and less efficient as time goes on. The following measurements, made at the start of each month, show the rate at which pollutants are escaping (in tons/month) in the gas:
Time (months) 0 1 2 3 4 5 6 Rate (tons/month) 6 8 12 16 23 33 45
A. Make an overestimate and an underestimate of the total quantity of pollutants that escape during the first month.
overestimate = __________ tons
underestimate = _________ tons
B. Make an overestimate and an underestimate of the total quantity of pollutants that escape for the whole six months for which we have data.
overestimate =
underestimate =
