Answer to Problem 42RP
The number of lines formed is
Explanation of Solution
Given information: The following information is given in the question
- Any four of them are non colinear
- No three of them are colinear − we will assume for maximum lines to be determined
Formula used: Number of lines formed by n points with no three of them colinear
Calculation: We will work on the above equation with
Substituting
Thus, the number of lines formed is
b
To calculate: The minimum number of lines determined in the paper are to be found
b
Answer to Problem 42RP
The number of lines formed is
Explanation of Solution
Given information: The following information is given in the question
- Any four of them are non colinear
- Two sets of three are colinear − we will assume for minimum lines to be determined
Formula used: Logical reasoning is used
Calculation: Using the above statements, we can see that for two sets of colinear points, we will have only two non colinear lines
Thus, the number of lines formed is
