Answer:
Mean = 6.3
Median = 6
Step-by-step explanation:
Measures of centre, mean and median, can be calculated as follows:
First, bear in mind that each dot represents a value in the data set.
==>Mean:
Mean is the sum of all values in the data set divided by the number of data set we have.
The sum can be calculated as follows:
0 (1) = 0
4 (3) = 12
5(8) = 40
6(3) = 18
7(1) = 7
8(5) = 40
9(2) = 18
10 (3) = 30
Sum = 0+12+40+18+7+40+18+30 = 165
No of data set = 26
Mean = 165/26 = 6.346 ≈ 6.3 (nearest tenth place)
==>Median: this is the middle value in the data set. Since the number of data set is even number (26) , the middle value lies between the 13th and 14th data points. The average of the 13th and 14th data points will give us the median value.
Thus, the 13th and 14th values are both 6.
Therefore, median = (6+6) ÷ 2 = 6
When the ball is first dropped, it falls 
feet. On the first bounce, it rebounds 
feet, which means on the second "drop" it must travel feet again. On the second bounce, the ball rebounds 
feet, and on the third drop falls the same distance. And so on.
So there are two directions to track:
The total distance is the sum of these two:
Recall that for an infinite geometric sum, you have
provided that
. So the total distance traveled by the ball is
Starting with a height of
means the total distance is about 152.42 ft.
