Answer:
Calculate, in kPa, the pressure exerted by a column of water that is 10-m tall. Assume the weight density of water to be and ignore the pressure due to the atmosphere.
Step-by-step explanation:
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>

The sum of angles of a triangle is 180°, so m∠K = 180° -45° -30° = 105°.
The Law of Sines tells you
... FL/sin(∠K) = FK/sin(∠L)
Solving for FL, we get
... FL = FK·sin(∠K)/sin(∠L)
... FL = a·sin(105°)/sin(30°) = a·sin(105°)/(1/2)
... FL = 2a·sin(105°) ≈ 1.93185a
Jacob is incorrect. The transformation was no a reflection, but a translation. The transation was (x+11,y+6)(11 units rigth and 6 units up). (Explain what the points would have been if it was a reflection across the x-axis)
