You would need to find the area of the brownies first and then ice them
A) T(m) = -0.16m +331.3
B) T(2015) = 8.9 . . . seconds
_____
The linear regression function of a graphing calculator can find the equation of the line easily. Or, you can use the 2-point form of the equation of a line.
.. T(m) = (10.5 -14.5)/(2005 -1980)*(m -1980) +14.5
.. T(m) = -0.16(m -1980) +14.5

2x = 4
x = 2
Hey Dammy17,
Ok so what we need to do is "plug in" 2oz for x in the equation,
So, 0.6 (2) + 11 =
0.12 + 11= 11.12 oz is the finishing weight.
