The table shows the data of a random sample of fish that were collected from and later released into a lake.
type of fish bass eel gar
number of fish 92 56 52
how many gars are estimated to be present if a random sample of 1,000 fish is collected from the lake?
104
108
260
320

There was a total of 200 fish collected and released from the pond...of those, 52 were gar52/200 = 0.26 = 26%

so if 1000 fish are collected26% of 1000 = 0.26(1000) = 260 gar <==

Best answer that i found on yahoo ok   set :   x= length of 2nd piece in cm  x- 3= length of 1st piece in cm  x-4= length of 3rd piece in cm  then since you know they all came from the 20 cm ribbon you add them together and set them equal to 20x+ x-3 +x-4 = 20  3x - 7= 20  3x= 27  x= 9  the shortest piece is the third piece which is x- 4  x-4  9-4 = 5  the length of the smallest piece is 5 cm.  the other lengths are  9 cm  6 cm
