The neck length was recorded for 5 different giraffes. each measurement has been rounded to the nearest 1/2 foot. measuments:5 4 1/2 6 5 6 1/2. How much longer are the two longest necks than the two shortest necks?

Answer: Difference between two longest and two shortest necks is 3 foot.

Step-by-step explanation:

Five giraffes having five different neck lengths as

Giraffe (1) = 5 foot

Giraffe (2) = 4.5 foot

Giraffe (3) = 6 foot

Giraffe (4) = 5 foot

Giraffe (5) = 6.5 foot

Now in the given question difference between two longest necks and two shortest necks were asked.

So total length of tow necks are Giraffe (3) + Giraffe (5) = 6+6.5 = 12.5 foot

Now total length of two shortest necks are Giraffe (2) + Giraffe (1) or Giraffe (4) = 4.5+5 = 9.5 foot

Difference between two longest and two shortest necks will be = 12.5-9.5 = 3 foot.
