1/2 (8+4)= 6
1/2(-1+4)= 1.5
1/2 (2+4)= 3
1/2 (4+4)= 4
So the correct answer would be A(8)

Answer:
522
Step-by-step explanation:
The assumption is that the proportion of tagged fish caught is the same as the proportion of all fish that were caught and tagged:
(all fish)/(number tagged) = (sample size)/(number in sample tagged)
all fish = (number tagged) · (sample size)/(number in sample tagged)
all fish = 174 · 39/13
all fish = 522
If all the assumptions are reasonable, the number of fish in the lake is estimated at 522.
Answer:
Answer B.
Step-by-step explanation:
x+2y=10
2x+8y=16
x=-2y+10
2x+8y=16
2(-2y+10)+8y=16
-4y+20+8y=16
4y=-4
y=-1
x=-2y+10
x=-2(-1)+10
x=2+10
x=12
