Step-by-step explanation:
Answer: ( 0, -2 )
Step-by-step explanation:
y = mx + b
x + 2y = -4
2y = x - 4
_______
2 2
(y = - 2)
Median and IQR are the most appropriate measures of center and spread for this data set.
<h3>Why are
Median and IQR the most appropriate?</h3>
Among the 3 central tendencies that includes the mean, median and mode; the median is the better measure because of the followings:
- Mean is affected by extreme values
- Mean is not correct if more outliers are present
- Mean may not represent the nature of the data whether skewed right or left.
Also, the median as the middle entry is not affected by extreme items or outliers, so the median is better than mean,
Furthermore, for the measure of spread, the IQR is better since extreme items will show higher std deviation and also some outliers mislead.
Therefore, Option B is correct.

<1 = <2
vertical angles (congruent)
<3 = <2
corresponding angles (congruent)
so that: <1 = <2 = <3 = 112 degree
Answer:
<em>S = 151°</em>
Step-by-step explanation:
Recall that the sum of the measures of the interior angles of a polygon with n sides is (n – 2)180.
Here we have a polygon with 5 sides (n=5), so the sum of its interior angles must be
(5-2)*180 = 540°
So
P+Q+R+S+T = 540°
(10x-3)+(5x+2)+(7x-11)+(13x-31)+(8x-19) = 540°
43x - 62 = 540
43x = 540 + 62
43x = 602
x = 602/43
x = 14°
The angle S equals 13x - 31 = 13*14 - 31 = 151°
S = 151°
You can compute all the other angles as well.
