pickupchik [31]

Answer:

The answer is "789.03 and 806.16".

Step-by-step explanation:

y\^ \ \ = -0.45 + 3.78(x)  -11.88(d_1) + 5.25(d_2)

For point a:

Calculating the value for y\^  \ \  x = 212,\ \  d_1 = 1, and  \ \ d_2 = 0

y\^  = -0.45 + 3.78(212)  -11.88(1) + 5.25(0)

     = -0.45 + 801.36 -11.88 + 0\\\\= 789.03  

For point b:

Calculating the value of y\^ \ \ for \ \ x = 212, \ \ d_1 = 0, and \ \ d_2 = 1

y\^  = -0.45 + 3.78(212)  -11.88(0) + 5.25(1)  

    = -0.45 + 801.36 -0 + 5.25\\\\= 806.16
