# Question Solved1 Answer14 and 15 is not correct 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: 5 6 Time (months) 0 1 2 3 4. Rate pollutants escape 7 9 10 12 15 18 22 (c) How many measurements would have to be made to find overestimates and underestimates which differ by less than 1 ton from the exact quantity of pollutants that escaped during the first six months? Round your answer to the nearest integer. Measurements would have to be made every i ! day(s).
