26 out of 130 were marked.
Divide 26 by 130:
26/130 = 0.20
20% of the bass caught were tagged.
Now divide the total amount caught and tagged by that percentage:
258 / 0.20 = 1,290
There are 1,290 bass in the lake.
Answer:
1,290 bass
Step-by-step explanation:
In City Lake, researcher caught, marked and released 258 bass.
When they took a sample
26 out of 130 bass were marked = [tex]\frac{26}{130}[/tex]
We calculate the percentage of 26 out of 130 = [tex]\frac{26}{130}\times 100[/tex]
20%
Let the total number of bass in the lake = x
20% of x = 258
0.20x = 258
x = [tex]\frac{258}{0.20}[/tex]
x = 1,290
Estimated number of bass in the lake would be 1,290.
