The dot plot uses dots to for data representation.
- <em>The dot plot is right skewed</em>
- <em>There is an outlier, 9.</em>
- <em>The best measure of center is median</em>
<u>(a) The description</u>
From the dot plot (see attachment), we have the following observations,
- <em>There are more data at the left-hand side, than the right-hand side of the dot plot.</em>
- <em>There is only one data element at the right-hand side</em>
<em />
This means that the dot plot is right skewed
<u>(b) Outlier</u>
From the dot plot, we can see that 9 is relatively far from the other data elements.
This means that 9 is outlier
<u>(c) Measure of center</u>
In (b), we established that the dot plot has an outlier.
When there is an outlier, the best measure of center to use is the median.
<em>Hence, the median will be used as the measure.</em>

Answer:
$551.25
Step-by-step explanation:
$450 x 7.5% = 33.75
33.75 x 3 = 101.25
101.25 + 450 = 551.25
17∠x-11 set up the equation like this
28∠x add 17 to the other side, and you get x is greater than 28
