Natalie performs a chemistry experiment where she records the temperature of an ongoing reaction. the solution is 93.5°c after 3 minutes; 90°c after 5 minutes, 84.8°c after 9 minutes; 70.2°c after 18 minutes; 54.4°c after 30 minutes; 42.5°c after 37 minutes; and 24.9°c after 48 minutes.
it says to perform a linear regression
1) what does the value of the correlation coefficient tell you about the correlation of the data?
2) write the equation of the best-fitting line. (round to the nearest thousands)
3) on average how much does the temperature decrease every five minutes?
4) if natalie's solution is expected to freeze at -7°c, how many minutes into the experiment should the solution freeze?
i think i got the right answers i just want to make sure once again. if you can. all is appreciated. i suck at this algebra stuff. you very much

Afunction g(x) has x-intercepts at (, 0) and (6, 0). which could be g(x)? g(x) = 2(x + 1)(x + 6) g(x) = (x – 6)(2x – 1) g(x) = 2(x – 2)(x – 6) g(x) = (x + 6)(x + 2)
