Given the steps used to calculate the interquartile range, Bryan did not make any mistake.
<h3>What is the interquartile range?</h3>
The interquartile range is the difference between the third quartile and the first quartile.
- Third quartile = 3/4(n + 1) : 3/4 x 10 = 7.5 term : (14 + 16) / 2 = 15
- First quartile = 1/4 x (n + 1) 1/4 x 10 = 2.5th term : (6 + 6) / 2 = 6
- Interquartile range = 15 - 6 = 9

Answer:
(7.5,3)
Step-by-step explanation:
( (x_1 + x_2)/2, (y_1 + y_2)/2 ) <--Midpoint formula
(5,5) and (10,1) are where you take the x and y values from. The x_1 and y_1 values come from (5,5) and x_2 and y_2 from (10,1).
this gives you ( (5+10)/2, (5+1)/2 )
=( 15/2, 6/2 )
=(15/2, 3)
= or (7.5, 3)
Both bold answers equal the same thing, just depends on if your teacher is asking for it in mixed number form or decimal form.
By the way, I realize it's confusing so the _ is just to show that the following number would be subscript (brainly won't let me show it, so I suggest searching it online if you are still confused..)
Hope this helps!
