The average change in temperature in each minute would be A) -1.1ºF and B) -1.7ºF.
To A) write an expression that represents the average change in temperature each minute, and B) if Edgar repeats the experiment and finds the average change in temperature each minute is 1 ° F greater in the second trial than in the first trial, to determine what is the average change in temperature each minute in the second trial of the experiment, the following calculations must be performed:
A)
(-2 x 4 + -3 x 3 + 6) / 10 = X
(-8 + -9 + 6) / 10 = X
-11 / 10 = X
-1.1 = X
B)
(-3 x 4 + -4 x 3 + 7) / 10 = X
(-12 + -12 + 7) / 10 = X
-17/10 = X
-1.7 = X
Therefore, the average change in temperature in each minute would be A) -1.1ºF and B) -1.7ºF.
