Best estimate for the bee population is 1280.
Step-by-step explanation:
Randy marked total number of bees = 160
Then he collected 240 bees and observed that number of bees marked
= 30
We have to find the total population of the bee or best estimate for the bee population.
Now we use the ratio of marked bees in the sample vs marked bees in the total population


x = 
Therefore, the best estimate for the bee population is 1280.
Answer:
Its D, 5 4/9
Step-by-step explanation:
So you can turn them into improper feactipons if it’s hard at first (I can already do it without turning them into improper so it’s asker for me)
so 19/9-2/9+32/9
Now add them like you normally would since all the denominators are the same.
you’ll get 49/9
now just simplify that into a mixed mnumber
5 4/9
