Answer:
57 degrees
Step-by-step explanation:
Angle Ad is 123 and since it's on the same line it adds up to 180 180-123=57
We know that
The residual value is the observed value minus the predicted value.
RESIDUAL VALUE=[OBSERVED VALUE-PREDICTED VALUE]
where
Predicted value.--> the predicted value given the current regression
equation
Observed value. --> The observed value for the dependent
variable.
in this problem
predicted value for x=3 approximate y=3.6
observed value is for x=3 y=5
so
RESIDUAL VALUE=[5-3.6]------> 1.4
the answer is
<span>
the best estimate of the residual is 1.5</span>
Y=10x+20
y=10×5y+20
y=50y+20
-20=50y-y
-20=49y
y=-20/49
