Answer:
Original data: 21 29 32 38 38 45 50 64 72 100
Mode =38.
Change 1: 2 29 32 38 38 45 50 64 72 100
Mode =38.
Change 2: 29 32 38 38 45 50 64 72 100
Mode =38.
Step-by-step explanation:
Original data: 21 29 32 38 38 45 50 64 72 100
The mean is calculated with the following formula:
And if we replace we got:
The mode is the most repeated value in the sample and on this case is Mode =38.
Since we have an even number of points the median is calculated as the average between the observations 5 and 6 from the dataset ordered.

Now the sample size is 9 instead of 10

The mode is the most repeated value in the sample and on this case is Mode =38.
Since we have odd number of points the median is calculated from the 5 position of the dataset ordered.
<u>Answer: </u>
The soccer ball hit the ground at (8, 0)
<u>Solution: </u>
To find at what point the ball hit the ground we make the given function equal to zero.
Here the given function is
We make h(x) = 0 and try to find the value of x
h(x) = 0
-8x (x - 8) = 0
-8x = 0 or (x - 8) = 0
Therefore x = 0 or x = 8
At x= 0 the ball was not kicked. Now we try to find the value of the function by substituting x = 8 in the given function and find the value of the function.
=-512 + 512 = 0
Thus the ball hit the ground at (8,0).
