Answer:
We can determine from their equations whether two lines are parallel by comparing their slopes. If the slopes are the same and the y-intercepts are different, the lines are parallel. If the slopes are different, the lines are not parallel. Unlike parallel lines, perpendicular lines do intersect
1/3 of 120 is 40
1/4 of 120 is 30
therefore, 10 more scouts in the first group elected to go on the trip
You can create and solve a proportion to get this answer.
Let x be the number of litters in 2500.
1. Write out proportion. 1/1000=x/2500
2. Cross Multiply. 1000x=2500
3. Divide by 1000 on each side. x=25
You want the average?
add them all together and then divided by the number of events
