after they are assigned
7*6 for the either gender
20+30+42 =92 total ways
or
20*30*42= 25200 total ways
Answer:
The lines are perpendicular
Step-by-step explanation:
we know that
If two lines are parallel, then their slopes are equal
If two lines are perpendicular, then their slopes are opposite reciprocal (the product of their slopes is equal to -1)
we have
----> equation A
isolate the variable y
Divide by 7 both sides

The slope of the line A is 
----> equation B
isolate the variable y
Divide by 3 both sides

The slope of the line B is 
Compare the slope of both lines


so
----> the lines are not parallel
Find the product of the slopes
----> the lines are perpendicular
