Let us calculate the median; the 6th observation is 20, so it is 20. We need the 6th observation so that out of the 11 observations we have 5 above the median and 5 below (or equal). We also have that then Q1 is the median of the lowest 5 observations, hence 19 (14,16,19,19,20, the 3rd observation is 19). Similarly, we get that the median for the upper half of the observations, Q3 namely, is 22 (21,21,22,22,23, the 3rd observation is 22). Thus, the interquartile range is 3=Q3-Q1. According to our calculations, all observations are wrong.
The equation of a circle is always the same:
where (h, k) is the center of a circle and r is its radius. So, we have:
The answer is
the last one.
From the Figure We can Notice that :
Opposite Side - AB = 1
Adjacent Side - OB =
We know that :
⇒ θ = 30°
We know that :
⇒
⇒
⇒ AO = 2

Answer:
Length: 16
Width: 8
Step-by-step explanation:
W + W + L + L = P
8 + 8 + 16 + 16 = 48
48 = 48
