Answer:
x = 21°
Step-by-step explanation:
Vertical angles have the same measures, therefore:
3x - 30 = 2x - 9
x - 30 = -9
x = 21°
Answer:
Only 60 is an identified outlier
Step-by-step explanation:
Given
<u>Age group: 40 to 50</u>


<u>Conditions for outlier</u>


<em>See attachment for complete question</em>
<u>Required</u>
Which of 60, 62 and 84 is an outlier of age grout 40 to 50 years
First, calculate the IQR of group 40 to 50.
This is calculated as:

Where:
and 
So:


<em>Next, is to test the outlier conditions on each value (i.e. 60, 62 and 84)</em>
<u></u>
<u>Testing 60</u>
<u>Condition 1</u>



--- False
<u>Condition 2</u>



--- True
<em>Because one of the conditions is true, then 60 is an outlier of group 40 - 50 years</em>
<em></em>
<u>Testing 62</u>
<u>Condition 1</u>



--- False
<u>Condition 2</u>



--- False
<em>Because both conditions are false, then 62 is not an outlier of group 40 - 50 years</em>
<em></em>
<u>Testing 84</u>
<u>Condition 1</u>



--- False
<u>Condition 2</u>



--- False
<em>Because both conditions are false, then 84 is not an outlier of group 40 - 50 years</em>
