Problem

oil A, in gallons used to heat the house per month for 5 months and the average monthly temperature t, on degrees fahrenheit, for those months. the scatter plot shows the data. the function A (t)=-1.4t+96 best fits these data.

Solution

We have the following function given:

A(t)= -1.4t +96

For case A if we replace t= 10 we got A(10)= -1.4*10 +96= 82 (True)

For case B if we replace t=15 we got A(15)=-1.4*15 +96= 75 (False)

For case C if we t=68.5 we got A(68.5)=-1.4*68.5 +96=0.1 (False)

For case D if we replace t=55 we got A(55)= -1.4*55 +96= 19 (False)

For case E if we replace t=0 we got A(0)= -14*0 +96=96 (True)

Answer:

A and E
