What is the median of the data in this stem-and-leaf plot?

It would be 23.

To get the median, first you would have to list all of the numbers from the stem-and-leaf plot in order:

14, 15, 17 ,21 ,22 ,24 ,24 ,26 ,30 ,32
Then you have to find the number in the middle. 

22 and 24 are in the middle.

However, we can't have 2 numbers as the median!
We would add both of the numbers then divide by 2, or you could use the number that is between 22 and 24.

22 + 24= 46
46/2 = 
23

The answer would then be 23

(*To tell whether the median is 2 numbers, check and count the set of numbers and see whether if the result is an even or odd number. Odd number have 1, while evens has 2.)

You need to divide 210 square inches by 35 inches and that’s going to give you 6 inches and that’s the length of the hypothenuse of the right triangle i hope that this you : )
