Question

PLEASE HELP I'VE BEEN DOING THIS FOR 2 HOURS!!

Answer 1

–0.507x2 + 14.907x – 36.131

Answer 2

The correct answer is:

b.) –0.507x2 + 14.907x – 36.131

Explanation:

First we enter the data into a graphing calculator. The times are the x-coordinates and the temperatures are the y-coordinates; this is because temperature is dependent upon time.

After we enter this, we run a regression on the calculator. We will run the quadratic regression; the equation is of the form

y = ax²+bx+c.

The values we are given on a Casio fx-9860 gii are:

a = -0.507

b = 14.908

c = -36.136

This is closest to choice B.
