How was Thanksgiving weekend?

Read the handout provided in the class. 1) Plot the data 2) Draw a curve (volume(cups) vs Fill time per cup (sec)) using regression. 3) print out the plot and submit it (don’t post here)  

Showing now! How are you today? We will cover regression more today!!

Plot this data set using regression (first-order) x=25,30,35,40,45 y=5,260,480,745,1100

First order regression

How are you today?

1) Solve T1, T2, T3 T1+T2+T3 -400 = 0 1600-10*T2-5*T3=0 2)Solve x, y, z 12x-5y=11 -3x+4y+7z=-3 6x+2y+3z=22 3) See the whiteboard  

How was the midterm exam? Was it easy to solve or difficult to understand?
