Answer:
(A) It is less than the contribution predicted by the regression line.
Step-by-step explanation:
The residual is the subtraction of the observed value by the predicted value.
So, if James has a negative residual, it means that his contribution is less than what was expected by the regression line.
The correct answer is:
(A) It is less than the contribution predicted by the regression line.
The equation of the polar curve 
is an even cosine function.
<h3>Polar curves</h3>
In geometry, polar curves are curves that are represented by the polar coordinates such that they are drawn around a fixed point
The equation of the polar curve is given as:
To graph the polar curve, we make use of the following representations:
- r represents the y-axis
represents the x-axis
Using the above representation, we can graph the polar curve
See attachment for the graph that represents

Option 2 8-12i is correct.
Step-by-step explanation:
The conjugate of the complex number is obtained by changing the sign of the imaginary part.
In complex number 8+12i
8 is the real part and 12i is the imaginary part
The conjugate of 8+12i is 8-12i
So, Option 2 8-12i is correct.

Isolate the d
divide 7 from both sides
c/7 = 7d/7
c/7 = d
d = c/7 is your answer
hope this helps
