136 10° +5 - Routara Trapped wind? Flatulent cows have come under renewed scrutiny by scientists who are hoping to reduce soaring levels of greenhouse gas pollution. Scientists in Argentina belleve they have come up with a solution -cow backpacks that can be used to trap the animar's natural gas In order to reduce green gas emissions as well as generate clean energy, scientists from Argentina have come up with a novel idea of capturing methane gas from cows' digestive tracts, using a cannula going from her digestive tract to a backpack. The scientist claims to capture at least 300 liters of methane gas per day, enough to run a car for 24 hours. You are to conduct a study to test the scientist's claim. State the null and the alternative hypotheses required to test the scientist's claim.

3) Jim rides a second Merry-Go-Round shown below. The distance, d, that Jim is from the wall can be described by the equation d = 38 + 22sin(8t), where t is the number of seconds since Jack was at the Start point. Answer the questions below (just enter the numbers), show ALL work, AND upload your work paper (or show your work) in the next question. The Merry-Go-Round makes one rotation every 45 seconds. Start 22 m 38 m Wall meters a) What is Jim's distance from the wall when t = 41 seconds? Round your answer to the nearest hundredth of a meter. b) The owner of the Merry-Go-Round decides to make the ride more exciting by tripling the rotational speed.
