In some gymnastics meets, the score given to a gymnast is the mean of the judges’ scores after the highest and lowest scores h
Allisa [31]

Using the median concept, the correct statement is given as follows:

Her median score does not change.

<h3>What is the median of a data-set?</h3>

The median of the data-set separates the bottom half from the upper half, that is, it is the 50th percentile, also called the middle value the data-set, not being affected by outliers.

For this problem, the data-set is given as follows:

7.50, 7.50, 7.75, 7.75, 8.00, 8.00, 8.00, 10.00.

There are 8 scores, hence the median is the <u>mean of the 4th and the 5th</u> scores, as follows:

(7.75 + 8)/2 = 7.875.

Removing the extreme values, the data-set will be given by:

7.50, 7.75, 7.75, 8.00, 8.00, 8.00.

Then it has 6 scores, hence the median is the <u>mean of the 3th and the 4th</u> scores, as follows:

(7.75 + 8)/2 = 7.875.

Same median, hence the correct option is:

Her median score does not change.

How can you use addition and subtraction to put together and separate measures if an angle and it's parts?
zalisa [80]
If you put two angles or more together, you add their total degrees to get the new angle. For subtraction, when you take a part off of a new angle you subtract the leaving one's degrees from the total of the one that is still there plus the angle that left. Hope this helps!
