The correct rectangular equivalence of 3sqrt(2)·cis(7pi/4 ) is:
3sqrt(2)·cos( 7pi/4 ) + i·sqrt(2)·sin( 7pi/4 ) = 3 - 3i.
<h3>Where did David go wrong?</h3>
David mistakenly interchanged the Sin function and the Cos function when he was calculating the problem.
Hence the correct rectangular equivalence is:
3sqrt(2)·cos( 7pi/4 ) + i·sqrt(2)·sin( 7pi/4 ) = 3 - 3i.
<h3>What is rectangular equivalence?</h3>
An equation is rectangular in form when it is comprised of Variables like X and Y and can be represented on a Cartesian Plane.

Answer:
D
Step-by-step explanation:
sampling distribution is statistical representation of statistics of each sample. So for a class size of 30,
A. number of samples have to be very large and defined in sampling distribtuion so this option is nullified
B. sample collection in sampling distribution is done without replacement of individuals so this option is nullified
C. this explanation doesn't match with the definition so this option is nullified
D. It is the correct option
