2.86 pts D Question 12 Figure A Figure 8 Figure C Figure D Refer to the figures above. Which of the figures show(s) a negative relationship between x and y? O Figure IB O Figure D O Figure C O Both Figure A and Figure B o Figure A

Solution

Question 12. Figure B represent negative negative relationship between two variables X and Y. The reason is that as the value of x increases the value of y is decreasing which shows negative relationship between the two.

Question 13. Figure A and figure D are showing positive relationship between X and Y. The reason is that as the value of x is increasing the value of Y is also increasing.

Question 14. Note that when we are at E both the quantity and the total revenue are increasing. This indicates that the slope is positive and therefore when we are at F, the slope turns negative. The correct answer is slope of the tangent at E is positive and the slope of tangent at F is negative.

Question 15. When two variables are not related to each other the relationship between them can be shown as a straight line which is horizontal or vertical.

Ocean 16. Ceteris paribus means all other things or factors are unchanged while we discuss about bringing a change in one of the factors. Other things remaining the same should be correct.
