You want to estimate how many fish there are in a pond. Suppose you cature 140 fish, tag them, and throw them back into the pond. After a couple of days, you go back to the pond and capture 420 fish, of which 28 are tagged.

~2,100.

well first I need to know how many fish are in the pond

Bro. What bait are you using? That's an insane amount of fish to catch in one day.

Stop taking pictures of fish, OP.

inb4 miscmathmatician

Well, I got her number. How do you like them fish?

350

Just throw a dynamite in there, ****git.

its this

I just got it

repped

about 350

Don’t worry OP. There are plenty more fish in the sea.

Got 2,100 as well

28 is 6.6666% of 420

120/.06666666 = 2,100

Lmfao this

He's probably using a net.

Can confirm 2,100. Was correct on the test.

Just learning statistics.

Gjdm. I hated stats.

imagine if you were a hot girl in her sexual prime and could basically get smart betas to do all your homework by tempting them with the possibility of sex

i get the calculation and the final answer. but could u tell me why and walk me thru it.

why did u divide 140 with the result of dividing 28/420

cheers

she was the best fish man

They gave him an intelligence test. The first question on the math part had to do with boats on a river: Port Smith is 100 miles upstream of Port Jones. The river flows at 5 miles per hour. The boat goes through water at 10 miles per hour. How long does it take to go from Port Smith to Port Jones? How long to come back?

Lawrence immediately saw that it was a trick question. You would have to be some kind of idiot to make the facile assumption that the current would add or subtract 5 miles per hour to or from the speed of the boat. Clearly, 5 miles per hour was nothing more than the average speed. The current would be faster in the middle of the river and slower at the banks. More complicated variations could be expected at bends in the river. Basically it was a question of hydrodynamics, which could be tackled using certain well-known systems of differential equations. Lawrence dove into the problem, rapidly (or so he thought) covering both sides of ten sheets of paper with calculations. Along the way, he realized that one of his assumptions, in combination with the simplified Navier-Stokes equations, had led him into an exploration of a particularly interesting family of partial differential equations. Before he knew it, he had proved a new theorem. If that didn’t prove his intelligence, what would?

Then the time bell rang and the papers were collected. Lawrence managed to hang onto his scratch paper. He took it back to his dorm, typed it up, and mailed it to one of the more approachable math professors at Princeton, who promptly arranged for it to be published in a Parisian mathematics journal.

Lawrence received two free, freshly printed copies of the journal a few months later, in San Diego, California, during mail call on board a large ship called the U.S.S. Nevada. The ship had a band, and the Navy had given Lawrence the job of playing the glockenspiel in it, because their testing procedures had proven that he was not intelligent enough to do anything else.
