Answer:

<em>OPtion B. Both the mean and median will increase, but the mean will increase by more than the median.</em>

<em />

Explanation:

You should not need to do calculations to determine <em>how buying the horse affects the mean and median.</em>

Without the horse, there are 8 animals. When the data are ordered, the <em>median</em> is the average of the 4th and the 5th weights: (7 + 27)/2.

With the horse, there are 9 animals. The median will be the 5th weight: 27

Then, the median increases from (7 +27)/2 to 27.

What about the <em>mean</em>?

The horse's weight is well beyond the weight of the other 8 animals. The range increases from 160 - 2 = 158 to 900 - 2 = 898.

Then, when you calculate the mean inlcuding the weigth of the horse, there will be a high increase.

Thus, without further calculations, you can conclude that "<em>B. Both the mean and median will increase, but the mean will increase by more than the median"</em>

The graph of F(x) shown below resembles the graph of G(x)- x, but it has been changed somewhat. Which of the following could be
Fudgin [204]

We can solve this question in the following way. Looking at the graph, we see that F(x) is shifted from one unit to the right, and it is represented by | x - 1|. Then, we can multiply this result by 4 to have the final graph, since the graph is not inverted.

Therefore, the answer to this question is F(x) = 4 * | x - 1 |.
