Question 102363: You run some water into a pitcher, then cool it down by adding ice cubes.
You find that putting in 5 ice cubes cools the water down to 76°. Putting in
15 ice cubes cools the water down to 48°. Assume that the temperature of
the water varies linearly with the number of cubes you put in.
I found the equation. It is y=90-2.8x and the correlation coefficient is -1.
