Answer:
The median is the best measure of center for distributions C and D.
Step-by-step explanation:
The <u>median</u> is the best measure of center for skewed distributions or distributions with outliers because it is a <u><em>robust</em></u> statistic, meaning that outliers and skewed data have <em>little effect </em>on the median.
Meanwhile, the <u>mean</u> is a good measure of center for symmetric distributions since it is <u><em>non-robust</em></u>.
Answer A has a roughly symmetric distribution, and answer B has a uniform distribution.
Answer C has a left-skewed distribution, and answer D seems to have a right-skewed distribution (since the right tail is longer than the left tail).
Therefore, the <u>median</u> would be the <u><em>best measure of center</em></u> for choices C and D.
Answer:
28/21
Step-by-step explanation:
You would do 13-(-15) to find the numerator which is 28. Then you would do 8-(-13) to get the denominator which is 21.
X + 6 is greater than (>) or equal to (=) 15
(0,0),(1,3)
slope = (3 - 0) / (1 - 0) = 3/1 = 3
y = mx + b
slope(m) = 3
y int (b).....this is when x = 0...u have point (0,0)...this means ur y int is 0
now sub
y = 3x + 0 which can be written as y = 3x <===
we know that
m∠ZWY=m∠WXY --------> given problem
so
In the right triangle ZWY

In the right triangle XWY


<u>Find the value of b</u>
<u>Applying the Pythagorean Theorem</u>
In the right triangle XWY

therefore
<u>the answer is the option</u>
D) 9.4 units
