a- Give an example equation of each of the common surfaces in this course (plane, sphere, cylinder, cone, paraboloid) and describe feature(s) that distinguish its graph from the others.

b- If you want to determine an equation of a line that passes through the point (0,0,1) and that is parallel to the xy-plane, how many such lines are possible and what do they all have in common? Give equations of at least two DIFFERENT such lines are part of your response.

Solutions

Expert Solution

The common thing that such lines have is that the direction ratio in z direction is always zero.

The first week of the course you were asked to give an example of how you would use statistics in your job or everyday life. As expected, most of you gave examples of descriptive statistics. They were things like finding averages, using graphs or considering the chance of something happening. As you have now discovered there is an entire second branch of statistics called Inferential Statistics. In this post I am asking the same question but this time I want...
