Answer:
BC
Step-by-step explanation:
it would be BC because you are basically taking the angle and drawing an arrow to the opposite side. another trick would be choosing an answer choice without the letter in it. also you didn't put what shape so I assumed it was a triangle

What is the third quartile of the following data set?<br>
20, 21, 24, 25, 28, 29, 35, 36, 37, 43, 44
ivolga24 [154]
Answer:
37
Step-by-step explanation:
Before we find quartile, we have to arrange the data set in order first from least to greatest which this problem has already arranged the data for us.
Next, proceed with the calculation. The formula for finding position of quartile is:
![\displaystyle{Q_r = \dfrac{r(N+1)}{4}}](https://tex.z-dn.net/?f=%5Cdisplaystyle%7BQ_r%20%3D%20%5Cdfrac%7Br%28N%2B1%29%7D%7B4%7D%7D)
Where
means the rth quartile, N means number of data set. Since we want to find the third quartile, substitute r = 3 and there are 11 data so substitute N = 11:
![\displaystyle{Q_3 = \dfrac{3(11+1)}{4}}\\\\\displaystyle{Q_3 = \dfrac{3(12)}{4}}\\\\\displaystyle{Q_3 = 3\cdot 3}\\\\\displaystyle{Q_3 = 9}](https://tex.z-dn.net/?f=%5Cdisplaystyle%7BQ_3%20%3D%20%5Cdfrac%7B3%2811%2B1%29%7D%7B4%7D%7D%5C%5C%5C%5C%5Cdisplaystyle%7BQ_3%20%3D%20%5Cdfrac%7B3%2812%29%7D%7B4%7D%7D%5C%5C%5C%5C%5Cdisplaystyle%7BQ_3%20%3D%203%5Ccdot%203%7D%5C%5C%5C%5C%5Cdisplaystyle%7BQ_3%20%3D%209%7D)
So the position of third quartile is at 9th position which is 37.
Henceforth, the third quartile is 37.
