a) Determine the quadratic regression equation,CEt),for China's per-person carbon emissions,at t years since 1990 according to this data. CE(t)=at^2+bt+1.91 b) Estimate China's per-person emissions in 2050 using your model.
c)
Determine the linear regression equation,CPt),for the population in China,at t years since 1990,according to this data. (p Find the equation CT(t)=CE (t)* CP(t)and evaluate CT(33.What does this mean in this situation?
The following table contains information on the population and per-person carbon emission for the United States (US). Per-Person Carbon Emissions (metric Year Population (billions) tons per person) 1990 0.25 19.41 1995 0.26 19.22

1990,according to this data. f) Estimate US's per-person emissions in 2050 using your model. g) Determine the linear regression eguation,UP(t),for the population in the US,at t years since 1990,according to this data. h) Find the equation UT(t)=UE(t)* UP(t.Use your graphing calculator to determine when China and the US had/has/will have the same annual amount of carbon dioxide emissions.In other words,find when CT(t)=UT(t) i) The Paris Agreement is an international treaty on climate change. Countries,who have ratified the agreement, have pledged to lower their greenhouse gas emissions by 2030 and become emission net-neutral by 2050. It is estimated that the world needs to lower carbon emissions by at least 43% to hit the 2030 Paris Agreement targets.China is the largest producer of total carbon emissions. The US is the largest carbon emissions per person. What would you suggest to our elected officials to lower the US's carbon emissions and meet the Paris Agreement goal? j) Small changes help, too! Individuals can change their habits and reduce greenhouse gases. What will you do to lower your carbon emissions/footprint?
