It's designed to be easy enough for white kids to get into college, but too difficult for niggers. Also, our school districts are not created equal, so the standardized test makes sure not to set the bar too terribly high.

The SAT is a standardized test designed to be taken by ALL american high school students and designed to score them on a bell curve. As such it contains many "easy" questions to separate the true retards from the mildly retarded. But all the test is not like that, of course.

WRONG.

ALL MATHEMATICS IS EVALUATED FROM LEFT TO RIGHT

THE SAME WAY YOU READ SO THERE IS NO CONFUSION.

LEFT. TO. RIGHT.

that stupid cunt shouldn't even be teaching if she's just going to pontificate about the fact that she has to actually do her job for once in a year.

if you EVER got 1, you did it wrong, that's how it's always been.

Parentheses. Order of operations, from left to right. always.

SAT tests are basically an IQ test, which means they include dirt simple questions and ramp up to harder ones.

White American students far, far outscore British, German, and most European students, other than Finland and a couple other countries. This is easy to see when you view scores delegates by race in things like international PISA comparisons.

The reason US testing scores are lower in average is because our average includes 40 million sub-saharan african negroid descendants of slaves with an average IQ of about 85-90. The fact that you couldn't realize that yourself means you're bad at interpreting statistics.

>>127429497

No. The vast majority of american schools are good, and if you do the work and have intelligence you will be in decent classes. Some of the best schools are actually public schools in cities where there are not too many poor or minority students.

The joke stories that you see here are exceptions.

lots of american students can do things like derive e from the fact that it is the same as its derivative.

e^0 = 1

dy/dx at 0 = 1

so e ^ (0 + 1/n) = 1 + 1/n (dy = dx since dy/dx at 0 = 1)

(e ^ 1/n)^n = e = (1 + 1/n) ^ n

let n = 10000000

e = 2.71828

really depends, m8. most people who do actually important maths use top/bottom division which has implicit parens in its structure, so it's pretty easy to just go and evaluate everything right of the slash without thinking. only time i really ever saw the division sign used (÷) is on calculators and a few elementary school questions, fucking nobody else uses it, and the slash in programming is almost always going to have a paren on one side or another if it isn't a strictly binary op, so

Good for the Asians-- I'm talking about people who would never consider entering a field where advanced math (not sure what the quotes are for, it's a thing) was a requirement.
And if they did, then let them focus on it in first year college, or some other preliminary training, once they've decided to enter said field.
Instead of making them take umpteen hours of shit that they, in turn, don't really need; e.g. an engineering student forced to take 'x' hours of humanities courses, etc

50%. You've already picked a box containing a gold ball per the problem description, and there are two cases where that is possible, box 1 or box 2. One contains another gold ball, the other does not, hence 50%.

Retards will claim that since box 1 has two gold balls, it effects the probability. The problem description doesn't say that you picked a gold ball, it says you picked a box with a gold ball.

it's 50%.

This problem is underconstrained, because you don't know which decision families will make after the first child.

Assuming they keep fucking until they get a boy (and they have the time for that), the ratio will be 1:1.

Explanation: The probability to get n girls is 1/2^(n+1). For example 0 girls: 50%, 1 girl: 25%, etc. To get the expected number of girls per family, you need to sum 1/2^(n+1) from n = 0 to infinity. That's 1. The number of boys obviously is also 1.

In reality you need to factor in that women can't just keep popping out children and that they can only do it every 9 months.

this isn't Bertrand's paradox. The answer is 1/2.
>>
>>127432136

The issue comes from the use of "/" as a division symbol and then the implicit multiplication with the parentheses,

Which is why you should never, ever write a question like this.

I would consider that it should be read 20/(5(2*2)) based on the implicit multiplication. It's a shit question and should never be asked. Use fractions to make it obvious.

>This thread

1) If you didn't get 800 on the math SAT you're a literal retard, and if you can't do the entire test without a calculator OR writing anything down and get at least a 750 you'll never get a non-fast food job.

2) PEMDAS isn't a fucking law of nature, it's a rule of thumb people follow because no one wants to actually write all the fucking parentheses that math expressions technically should have.

3) Maybe some shitskin invented the plus sign or something 1500 years ago, but literally 100% of all progress in math in the last 300+ years has been by whites, chinks, and maybe a few poos.

Still 50/50. If this law was viable for 100 families, 50 would have a male kid as their first, while the other 50 would have a female kid. Assuming that the rest would want a second kid, 25 would be males, and 25 females; in total 75 males and 75 females. It could go on like this ad infinitum, but the ratio would still be 50/50. However, families with only female kids may decide to stop having kids even without having any male children, but idk how to take that into account. Families might also choose not to have kids at all.

$100

Even though $70 was returned, the store is still out $70 worth of goods in addition to the $30 in cash. Assuming the store manager isn't a retard, he would have bought the stock for less than $70, but because he looses not only the base value but also the profit he would have made selling to honest customers, the total monetary value lost that day is $100.

But it is worth noting that there are other potential costs associated with the fraudulent purchase. Opportunity costs, like a customer buying less/not buying anything because they couldn't have been helped by the employee(s) helping the woman, could potentially raise the total cost of the crime beyond $100.

There are 3 gold balls all equally likely to be picked. When you pick one gold ball it has 2/3 to come from the left box and 1/3 to come from the middle box. If you picked from the left box your chance for a 2nd gold ball is 100%, if you picked from the liddle box it's 0. So the chance of picking a second gold ball is 2/3.

Imagine this : each box has 100 balls in it, left box is 100 gold balls, middle is 50 gold and 50 silver, right is 100 silver. You pick 50 balls at random from one box without looking at the box and you get 50 gold balls, how likely is it that you picked from the middlebox ? How likely is it that you picked from the left box ?

They're both countable infinities. There's a bijection from the squares to the natural numbers.
>>
>>127433133
Nope. If you ever need PEMDAS, it's because there aren't enough parentheses to unambiguously determine the order of operations. It's nothing but a crutch to keep everyone from needing 200 parentheses for every equation.

Even "1+2+3" isn't technically parenthesized enough, because it doesn't tell you which two numbers to add first (even though it doesn't matter in this case). "6/2*3" is ambiguous because it's grammatically incorrect, not because we need to specify an order of operations.

The entire public education system is set up that way, honestly.
All kids are taught in the same classes until high school, for the most part. And all classes and subjects are taught with an eye to improving test scores for the school, so actual education is disregarded while kids with potential spend years poring over the same old things so that the nogs and idiots can keep up and not drag the school's performance down.

Imagine how full the more advanced classes might be if so many kids weren't ground down by mass-production, assembly line (mis)education practices.

Up until High school, more or less. Some places have more advanced placement classes earlier on, but the enrollment is usually relatively small.
So basically, you're either one of the math nerds, or a "regular joe", which means a person of average or even above average ability is crammed in with complete morons and forced to work at their level.
