Using six random samples, the average number of catfish in the samples was 5.7. if the total population of fish in the pond is 200, the proportion of catfish in the pond will be 5.7 20 = x 200 . what is the predicted number of catfish in the pond?

step-by-step explanation: h: (- 3, 6)

m: (1, - 2)

o: (7, 6)

r: (- 9, - 2)

midpoint of hm: (- 1, 2)

midpoint of or: (- 1, 2)

therefore, b is the midpoint of both diagonals bisect each other !

to prove the diagonals are perpendicular, show that the product of the slopes = - 1
