Ceteris paribus, I think the ratio would stay the same because it's a 50/50 chance of having a boy or a girl.


There are a lot of external factors, though.

Genetics make it so females are slightly more likely to be conceived than males.

A family might not want to keep having children if they get females since females were less valuable in a feudal society.

High infant death rate due to medieval medicine would make it so many families wouldn't have any children if their first was a son.

>>151011559
It is correct, most people fail to this problem though and answer "A" and "2".

>>151011741
Thanks.

>>151011474
A is obvious. 7 also needs to be turned over because the rule is not followed if there's a vowel on the other side.

Now, if we make the assumption that each hard has a letter on one side and a number on the other side, that's all there is to it. However, if we insist on rigour, then K would not follow the rule if the other side was a vowel. 2 would follow the rule regardless of what's on the other side.

>>151011877
I thought most people answer just "A".

>>151011401
>>151011834
Trigonometry is studying the relationship between side lengths and angle measurements in triangles. As long as we're only dealing with angle measurements then it's still elementary geometry.

The mass of the steel ball is being supported by the crane, so it does not contribute to the mass of the beaker of water.

The ping pong ball is lighter than water but still has mass, so it does contribute to the mass of the beaker.

>>151011741

Should tip towards the left, the ping pong ball is lighter than water, but not lighter than air, thus contributing to weight on the left side, while the steel ball will not (at least barely.) contribute to any weight on the right side.

>>151011834

There's no guarantee that every card has a number on one side and a letter on the other. Thus A, K, and 7 need to be flipped. 2 will satisfy the rule no matter what.

Ratio stays the same. Just compare the children who are the kth children in their family. For all k, the expected amount of boys and girls is the same. This implies that the sum over all kth boys and the sum over all kth girls are equal.

>>151011913
>>151012044
Why though? 2 isn't guaranteed. It could easily have a consonant on the other side.

>>151012130
The rule only applies to vowels, not even numbers. Even numbers can have anything on the other side.

>>151012130
That doesn't defy the rule though.
Nothing says that a consonant shouldn't have an even number on the other side.

>>151012117
prove it without trig then

this is only cultivating my intellectual domination fetish.

>>151012160
That doesn't make sense. If a vowel must have an even number, then an even number must have a vowel or the rules aren't being followed.

>>151010942

WAIT, I'm retarded. Didn't notice the 2 pints of beer so its 15.

>>151012221
Read the rule carefully. It only goes one way, not the other.

If it has a vowel on one side, it must have an even number on the other side.

It does not state anything that implies an even number must have a vowel on the other side.

Thus 2 will always satisfy the rule. If every card has a letter and a number, only A and 7 have to be flipped.

This might work out like Chinas one child policy, where they will keep having children until they get a boy to be the heir.

>>151012912
If you do the hexagon/triangle pattern throughout the entire plane then each hexagon would need to have 2 red triangles to connect the pattern.

If you tile the initial pattern then the values are fixed to the ratio you can count in the initial figure because it would have to be "rounded" in terms of that figure.

Do a trinary search and place 3 balls on each side of the scale.

>>151013318

There are 3 possible outcomes of the first weighing
>left side is lighter (light ball is in left group)
>right side is lighter (light ball is in right group.)

do the same again this time you have reduced it to 3 balls. Same possible outcomes.

>>151012901
>If the following pattern continues across a plane

Yes, it does extend indefinitely.

>If the figure in the image is tiled indefinitely
That figure can't even tessellate.

>>151013196
4 against 4
if they are the same then you know the last ball is it.

If not then you discard the heavier group, weigh the lighter group 2 against 2.

Then take the lighter group again and you will have a 1 v 1 to figure it out.

So minimum is just once? or am I retarded and not understanding the question. Or 3 times because that is the most you should ever have to do?

This problem is easy if you just look at it from the perspective of how much % of it is wine.

Let x be the proportion of wine left from the first day. Doing the same thing three times results in 50% wine. So x^3 = 0.5, and the proportion is 1 / ∛2. So 3 cups of wine = (∛2 - 1) / ∛2, thus there are 3∛2 / (∛2 - 1) cups in the barrel.

3∛2 / (∛2 - 1)
= 3∛2(∛4 + ∛2 + 1) / (∛2 - 1)(∛4 + ∛2 + 1)
= (6 + 3∛4 + 3∛2) / (2 - 1)
= 6 + 3∛4 + 3∛2 cups of water.

>>151013913
The words are chosen very carefully. The rule says a vowel must have an even number on the other side but noy vice versa. Only issue in the wording is that it doesn't specify whether cards have both a number and a letter or can have two from either. In the original problem, cards must have one of each on each side.

K is only a part of the answer if cards can have both sides be letters or numbers. 7 always must be flipped because it could have a vowel on the other side in either scenario.

>>151014159

If we are assuming any agitation caused by shooting at people it becomes a lot harder, but then his best chance is to aim at nothing.

If not he should shoot at black because Black will aim for Gray because its his highest chance at surviving.

>Shoot the air and miss both
>3/4 chance of Gray, 1/4 chance of Black
>4/13 chance of surviving Gray
>1/4 chance of surviving Black
3/4 * 4/13 + 1/4 * 1/4 = 3/13 + 1/16 = 61/208 = 244/832

>Shoot Gray
>3/4 chance of missing, move to 1st scenario
>1/4 chance of hitting Gray, move to Black, no chance of survival
3/4 * 61/208 + 1/4 * 0 = 183/832

>Shoot Black
>3/4 chance of missing, move to 1st scenario
>1/4 chance of hitting Black, move to Gray, 1/13 chance of survival
3/4 * 61/208 + 1/4 * 1/13 = 199/832

So for maximum chance of survival, White must deliberately miss first. But if he must shoot someone, shoot Black.


Note: Calculations for White vs Gray

White first
1/4 win
3/4 * 3/4 lose
3/4 * 1/4 * 1/4 win
3/4 * 1/4 * 3/4 * 3/4 lose
3/4 * 1/4 * 3/4 * 1/4 * 1/4 win
etc.
So White's chance of winning can be written as a geometric progression a, ar, ar², etc.
Here, a = 1/4 and r = 3/4 * 1/4 = 3/16.
Then White's chance of winning = a/ (1 - r) = a / (1 - 3/16) = (1/4) / (13/16) = 4/13

Gray first
3/4 win
1/4 chance of translating to above
This leaves White with 3/4 * 0 + 1/4 * 4/13 = 1/13 chance of winning.

The only viable solution would be to trick the population to head to various "shelters" for safety reasons.

Of course the shelters wouldn't actually do shit. But once they are all separated and concentrated it would be a lot easier to do the culling.

The only problem left would be to find a plausible system to send various people in different places.

First thing I would do is to explain my plan to the soldiers and the ruling body to ensure their loyalty by grouping their families and friends to specific shelters that will be absolutely safe. I'll stress out the fact that if they want to survive along with the people they love, their only chance is to follow my orders.

I would then order to block any form of communications. Internet, phone lines, everything. Last thing I'd want is for the news of the situation to spread out. Pretty much all the media will be put under control and occupied.

Personally I would simply put people on various shelters and then randomly chose which to eliminate, but humans are pretty emotional when it comes to children. I don't want some soldier to have moral issues when they are given the order to kill. I'll try as much as possible to send children and their parents to safe areas.

I wouldn't really use any other form of selection as it would just increase the chance of people suspecting something is wrong.

The Ideal method of elimination would be to seal the selected shelter and gas the people inside. But it might be necessary to order soldiers to open fire.

Case 1: Multiplication only works as repeated addition for positive integers. If your x is not an element of the integers, then x^2 = x + x + x + ... + x is false.

Case 2: If you choose x to be a positive integer, then x^2 is simply a constant polynomial => the derivative of both sides is 0.

1 Beer = 10
This is because 10 + 10 + 10 = 30

Thus
Beer + Burger + Burger = 20
Becomes
10 + Burger + Burger =20, Ergo Burger + Burger = 10
This means 1 Burger = 5

In the next question

Burger + 2 Beer + 2 Beer = 9
Note: the Beers are intentionally drawn as 2 in this question, as opposed to 1 in the final question
5 +2 Beer + 2 Beer = 9
Ergo
2 Beer + 2 Beer = 4
Thus we extrapolate
2 Beers = 2

Thus we establish
Bottle = 10
Burger = 5
2 Beers = 2

Ergo the Final question is
5 + 1 * 10

Thus even if you Fail at BIDMAS the answer is 15,
The trick is to notice the Beer Icon change between Q3 and Q4

Normally you would answer that you have 2 variables in the equation and state that the equation is not solvable without a logical leap that is to assume the single beer is 1/2 the value of the individual beer

> This is likely just a teacher being retarded

Unfortunately, it is not, in general, though I don't know about that specific case. There is a school of schooling that states that kids learn multiplication better if they learn to mechanically imagine x groups of y objects to visualize x×y, and only learn about commutativity later (because it is not obvious why 3 groups of 5 carrots and 5 groups of 3 carrots have the same number of carrots, one have to work with abstractions for that). The answers can be seen as coming from kid who groups by the wrong number. Of course, if someone already gets the multiplication, there is no point in teaching useless actions that will be discarded later, but, as usual, the curriculum evens the weeds that are considered equal if there is no good teacher making personal decisions.

That's just primary school and basic math. Now imagine how compulsory education systems wreck (or build?) the whole population.

I've read some good discussions of that problem recently.
