Answer:
<em>The residual value when x=2 is </em><em>-1</em>
Step-by-step explanation:
The difference between the observed value of the dependent variable and the predicted value is called the residual (e). Every data point has one residual. Lesser the residual value, better the best fit line is.
Mathematically,
Here from the graph,
the observed value is 2, so y=1
the predicted value is 0.5(2)+1 = 1+1 = 2, so
Putting the values,
Answer:
The area of figure ABCD is 24 square units.
Step-by-step explanation:
We see that the given points form the vertices of a trapezium ABCD with bases AD and CB with measure,
AD= 3 units and CB=5 units
and the height of the trapezium is AB= 6 units.
The area of trapezium ABCD is:
