The reasons that the sample is representative:
The builders were chosen at random
The population included only builders who build in Vicki's town

Answer:
136
Step-by-step explanation:
The two scales are supplementary, so the value on the second scale is ...
180° -44° - 136°
Expand it
-(x+3)^2-1
-(x+3)(x+3)-1
-1(x^2+3x+3x+9)-1
-1(x^2+6x+9)-1
-x^2-9x-9-1
-x^2-9x-10
f(x)=-x^2-9x-10
