Answer:
D.) The mean may change, but the median will not change.
Step-by-step explanation:
By adding two new values to the existing dataset ; this two values are extreme values as described in the dataset.;
As the warmer will be the new minimum and the colder the new maximum .
The median value being the midpoint of the dataset when arranged in order will definitely not be affected by these new additions are at the beginning and end of the data set. Hence, the previous median points will Also be the new median points.
As for the mean, it has to do with calculation the average value, despite the number being at the extreme, the new points may take up any value and hence will affect the new sum and ultimately the obtained average.
Therefore,The mean may change, but the median will not change.
The measure of its complementary angle is 87 degrees. When two complimentary angles are added to each other they equal 90 degrees.
<h3>Answer: 512</h3>
=======================================================
Explanation:
If you had one coin, then there are 2 outcomes because of the two sides heads or tails, which I'll shorten to H and T respectively.
With two coins, there are 2*2 = 4 outcomes (HH, HT, TH, or TT)
Having 3 coins there are 2*2*2 = 2^3 = 8 outcomes
4 coins and we have 2^4 = 2*2*2*2 = 16 outcomes
and so on
With 9 coins there are 2^9 = 512 different outcomes
