Answer:
7
Step-by-step explanation:
The median is the middle value of the data set arranged in ascending order.
If there is no exact value then it is the average of the values either side of the middle.
Arrange the data in ascending order
1, 4, 6, 8, 8, 9
The middle is between 6 and 8, thus
median = 
= 
= 7
While going to the ice
skating rink,
Rosario drives a distance of 55 miles in = 1 hour
Then
While going to the
ice skating rink,
Rosario
drives a distance of
120 miles in = (1/55) * 120
<span> = 2.18 hours</span>
The number of miles
per hour Rosario averages while coming back home = x
Total up and down
time taken by Rosario = 2.75 hours
Then time taken by
Rosario to come
back
home from ice
skating rink = (2.75 – 2.18) hours
<span> =
0.57 hours</span>
Then we can write
the equation as
x = 120/0.57
miles/hour
<span>
= 210.53 miles/hour</span>
<span>So the average speed
of Rosario while coming back home from ice skating rink is 210.53 miles per
hour.</span>
Answer:
To find the median, the data should be arranged in order from least to greatest. If there is an even number of items in the data set, then the median is found by taking the mean (average) of the two middlemost numbers.
81,83,91,94
since its an even number add up the two middle numbers 83 and 91 to equal 174 then divide by two to have the median of 87
