In the video we just saw, we found performed cubic regression for natural gas consumption levels over time and found or model equation to be C(t) = 0.00025t3 – 0.02879t² +1.13663t + 5.28333 where t is years after 1950. Use the model to predict natural gas consumption in 2020 in quadrillions of BTUS. Round to the nearest tenth and do not include units in your answer. Provide your answer below:
