Answer:
Yes there are three lines that are right beside each other making them parrel.
Step-by-step explanation:
Use distance = rate x time
18 minutes is 3/10 of an hour.
So the distance to the store is:
d = 20*(3/10) = 6 miles
The distance downhill is the same, 6 miles. So:
6 = (60)t
6/60 = t
1/10 = t
Where t is the time it took to go back home. So t is .1 hour (6 minutes).
To calculate average speed we use the formula:
average speed = total distance/ total time
average speed = (6+6)/(.3 + .1) = 12/(.4) = 30
So her average speed for the entire trip is 30 mph (miles per hour).
The mean is the average of a set of numbers.
An outlier is a number that is significantly higher or lower than most of the data set.
So, therefore, when you are calculating your mean, the outliers in your data set sway your average higher or lower.
In these instances, the median is usually a better indicator of central tendency.
