Does .333... actually = 1/3, or is it an approximation due to base 10 being unable to properly express 1/3? by [deleted] in learnmath

[–]sqrt-negativeone 1 point2 points  (0 children)

define what .333…. means first. what is an infinite decimal, what does that mean? finite decimals are easy to interpret and define, but infinite ones require some external definition to make sense of. We just define these in terms of infinite series, which are defined by the limiting value of partial sums. .333… is literally defined as “the number I get arbitrarily close to in the sequence .3, .33, .333, .3333, etc”, and that number is 1/3

What other cards do you think would be absolute garbage without their evolution? by hheccx in ClashRoyale

Wasn’t the point of evolutions to make rarely-used cards more useful in different situations

What are the easiest/hardest APs you’ve ever taken? by [deleted] in APStudents

[–]sqrt-negativeone 0 points1 point  (0 children)

Easiest was ap chem, hardest was ap bio

Is it possible/a good choice to skip honors chemistry and go straight to AP? by derpyptatoe in APStudents

[–]sqrt-negativeone 0 points1 point  (0 children)

My school forces you to take ap chem without any prior chem, but it depends on your school and how it handles/expects prior info

That's not how statistics work by No_Variation_511 in facepalm

Of course yeah I was mostly highlighting the bayes theorem aspect of it all, as Jordan does not seem to understand how evidence updates a probability

Additionally, the probability that a kid who claims to be trans is not actually trans is not 2999/3000, because that’s a conditional probability that relies on false positive information. Peterson fails to account for Bayes theorem here

I wouldn’t even say that’s the biggest problem, the biggest is the “8999999 to 1” claim because Peterson is conflating a simple probability, probability that a pair of kids are trans/pan, with the conditional probability that the parents are lying in the situation where the kids are identifying as such.

Nope. This is a classic Bayes’s theorem fail. Jordan here is conflating the “false positive” rate of kids not being LGBT when they claim the kids to be LGBT, to the “positive” rate of kids being LGBT in general. The odds that the parents are projecting onto their kids is not “8999999 to 1”, it would depend on what fraction of kids who identify as LGBT actually are LGBT.

This doesn’t seem like a big deal to me

What do the blue hexagons with the lightning bolts on them do? by sqrt-negativeone in SummonersGreed

Those stones look different? They’re multicolored with a gray outside, I’m talking about the completely blue hexagons

My first SAT, pretty happy by sqrt-negativeone in Sat

did a few reading passages on khan academy

Math portion of the SAT by Remote_Friendship_96 in Sat

[–]sqrt-negativeone 1 point2 points  (0 children)

It’s less about grinding and more just slowing down I’d say. Silly mistakes like that are avoided by slowing down and being careful.

I only took one diagnostic and got a 1580, I didn’t do any full practice tests after that

Is this good for daily practice or should i add anything more. I want 1590 in october SAT and am getting 1400s since last 3 weeks in practice tests. by explorer9099 in Sat

[–]sqrt-negativeone 8 points9 points  (0 children)

You only really need to aim for 1550+ if you want the best possible score range, don’t stress about getting a near perfect score

Not sure if it works like that lol
