Answer:
60°
Step-by-step explanation:
sum of interior angles of quadrilateral is 360°
∠C = 70°
∠D = 50°
∠C + ∠D = 120°
∴ ∠A + ∠B = 360° - 120° =240°
AO and BO bisect ∠A and ∠B
∠OAB + ∠OBA = 1/2 x ( ∠A + ∠B) = 120°
∠AOB = 180° - (∠OAB + ∠OBA) = 180° - 120° = 60°
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>
