Me fast? ? i need with a math question

To find the range, first order the data from least to greatest. Then subtract the smallest value from the largest value in the set.

In this problem is it a little complicated because you have to do it in two steps.

Stem 5   Leaf 4 5 (5-4 = 1)
Stem 6   Leaf 0 6  9 (9-0 = 9)
Stem 7   Leaf 2  3  4  5  5 (5-2 = 3)
Stem 8   Leaf 1  2  8  9  (9-1 = 8)
Stem 9   Leaf 5  6  (6-5 = 1)

So, now we have:
51
69
73
88
91

So we subtract 91-51 = 40 which is your answer.

Hope this helps.

The answer is 42 so b because range is the highest number - the smallest number which is 96-54 which equals 42

Maybe the answer is 20mm. all i really did was just multiply, which is obvious.
