Find the interquartile range (IQR) of the data in the box plot below. rebounds A horizontal boxplot titled Juan's number of rebounds each game, is plotted along a horizontal axis marked from 0 to 15, in increments of 1. A left whisker extends from 4 to 8. The box extends from 8 to 11 and is divided into 2 parts by a vertical line segment at 10. The right whisker extends from 11 to 13. All values estimated.

It says in the questions that it is 6.5?

Ask google i believe they can you with that question

Ok here we go ..there are plenty of ways to solve such math problems but we will go for the smartest and easiest ..5x+2y=7  -2x+6y=9we rearrange them into the following ..by multiplying the 1st equation by 2 it becomes 10x + 4y = 14we rearrange it and so it becomes 10x = 14 - 4yas for the second equation we multiply it by 5 and rearrange it so it becomes as to the following ..-10x + 30y = 45rearranging so 10x = 30y -45now 10x equals both 14 - 4y and 30y -45so   14 - 4y = 30y -4531 = 26yy= 31/26 = 1.19 or around 1.2so by now we can calculate x easily as  -2x+6y=9so 2x = 6y -9 = 6 * 31/26 - 9 = -1.84  then x = - 0.92 or around -0.9best luck!

The correct answer is b
