You don't have a logarithm in your problem

glossy gale
#

Sorry that was the entire question but mb for not showing you entirely what I wanted to do. I wanted to find the reference point

glossy gale
#

This was my work and how I got (-2, -3)

#

But I don't know exactly what "reference point" even means

#

Google didn't really tell me either

#

Did I do something wrong when converting?

zinc ginkgo
#

There's an example with base 2 instead of base 3

glossy gale
#

Alr one sec lemme get my computer

zinc ginkgo
#

So if you follow their example, yours will be very similarly done

trim joltBOT
#

@glossy gale Has your question been resolved?

glossy gale
#

Nvm I get it now! I had ot flip (-2, -3) since it was an inverse log function @zinc ginkgo

#

So it's (-3, -2)

#

thanks for ur help

Hello I've got following problem: A company mass produces lamps, of which on average 10% are defective. An electrician now buys 50 packs of 10 lamps each. Calculate the probability that exactly 40 of the packs of 10 purchased contain at most one faulty lamp. Could anyone help me to solve it.

slate wagon
#

I tried using double Bernoulli chain

#

But since the probabilities that came out had crooked values and we only have a table book to look them up - I guess that is not be the solution but feel free to correct me if I'm wrong

almost sounds like parametric bootstrapping thonk

<@&286206848099549185>

tepid atlas
#

what do you mean by crooked values?

slate wagon
#

For instance 0.8156382...

tepid atlas
#

ok so im a little bit rusty on my probability, but how would you find the probability a pack of 10 lamps has at most one faulty lamp?

#

if you can calculate that number, then i know how to solve it

#

a double bernoulli chain, after reading about it, does seem like the right approach

slate wagon
#

Do you think this is correct?

tepid atlas
#

i mean i am not up to speed on probability

#

like the notation or the distributions

#

my intuition tells me that 8% could be slightly high

#

but also there is some at most stuff happening that could even it out

#

B is for binomial distribution, with p = .1?

slate wagon
#

Yeah

tepid atlas
#

yeah actually this looks right

slate wagon
#

Okay thank you very much!

Lol, so if I help do I win the nitro?

#

What is this event?

winged bough
#

In server

crisp ibex
#

If its in this server

#

Then I'm already screwed

#

But any normie server

winged bough
#

And they casually do these events it owned by YouTuber

crisp ibex
#

So you're trying to cheat in an event to win nitro?

winged bough
#

Yep

crisp ibex
#

We live in a society

winged bough
#

We do?

#

How about this I give u 2 of the problems worth 1 nitro each and we split 50 50

tepid hamlet
#

Yes normally you dont inform someone of the intention to cheat in our society you would just ask the question, duh

crisp ibex
#

It's like I do both problems

#

And then you win half of it

#

(Tho from the looks of it if each problem is nitro I might not be able to do them)

glacial aurora
#

My linear algebra book keeps stating that "infinite linear combinations" dont exist, does anyone have any clue what this is supposed to mean

glacial aurora
#

Im thinking he might mean that any element in a vector space V can be described as a linear combination of the basis. (since a basis is finite (i think? havent really gotten to basis yet))

marble wharf
#

if you want to take "infinite sums", you first have to talk about what that means

#

that is, you need to have a notion of convergence

#

linear algebra ignores all that and just doesn't allow infinite sums

glacial aurora
#

hmm okey, so i can see it as an "axiom" of linear algebra

marble wharf
#

if you do linear algebra "with" infinite sums you end up doing functional analysis

#

sort of I guess

#

infinite sums don't have meaning without more structure on the space you are considering

#

and for most of a linear algebra course you just don't look at stuff like that

glacial aurora
#

works for me, thanks alot!

#

a small question again, is it worth learning about sums and direct sums of subspaces if i havent gotten to the concept of basis yet

marble wharf
#

sure

glacial aurora
#

my book talks about sums and direct sums b4 basis but i dont really get its explanation. While everything on the internet seems to explain sums/direct sums using basis

glacial aurora
#

thanks for the help!

Prove using cardinality definition that |AUB|=|A|+|B| if A and B are both disjoint and non empty finite sets

astral lily
#

If we suppose |A|=m and |B|=n then |AUB|=m+n so we need to prove that there is a bijection from N(m+n) to AUB

#

Not sure what to do after this. Probably need to define a new function but idk how

#

@marble wharf from what u weee saying earlier today

#

I’m guessing we’d define say h(i)=f(i) for 1<i<m where f is the bijection from Nm>A

marble wharf
#

1<=i<=m but yes

astral lily
#

Yeah that’s what I meant

#

And then h(i)=g(i) for m+1=<i<=m+n

marble wharf
#

nearly

#

h(i)=g(i-m)

astral lily
#

But we need it to be a bijection from to Nn

#

So <=n

#

So i-m

#

Yeah

#

Ok and now proving it’s a bijection is just trivial

marble wharf
#

yeah

astral lily
#

Ok thanks a lot

velvet raptor
#

How do i explain why 81^3/4 equals 27?

astral lily
#

Then cube it

velvet raptor
#

Thats 3 right?

astral lily
#

Yes sir

cerulean hemlock
#

$x^\frac{a}{b}= \sqrt[b]{x^{a}}$

solid kilnBOT
velvet raptor
#

So i would just say something like “the 4th root of 81 cubed equals 27”?

I think i got it thanks

Hey guys

trim joltBOT
wraith hinge
#

In this question we have to find f(n) in each case, why does the solution in the first problem write the form as

#

an=(an+bn+c)2^n

#

And not an=(an+bn+c)K2^n

#

This table shows the forms

#

Is it because it already is getting multiplied by a, b and c?

trim joltBOT
#

@wraith hinge Has your question been resolved?

wraith hinge
#

Nope

wise dagger
#

A simple yes for your question.
For example
(an²+bn+c)K = Kan²+Kbn+Kc
Can be transformed into
a'n²+b'n+c'
By letting a'=Ka, b'=Kb and c'=Kc

For details, you can search for "dummy variables"

hello there,
first about me: iam a software developer near a deadline about a problem ive been working on with my team for amolst a week now we dont manage to solve (i would be surprised if someone knows the answer due to its large complexity)

problem: we all dont know much about math we all dropped out of school and just started our coding startup xD

mathematical problem:
A) example: you have number y of things number x of ppl. (short for people) and number z representing lets say a "rank" or a "role" for each x with the lowest z (z can be used for multiple x with same value) gets the equal amount of a (a is the output) then the x with the next highest z gets 5% more on value of a than the x compared to previous x and at the end every a must be equal or lower than the original y

B) restrictions: (doest really matter for you but for us as devs) that its a fast algorithm in terms of using this equation or algebra function or whatever its going to be to calcuate things we need in our production process

anyone here might have an idea?

what we tried alrdy was going with an neural network we train based on hand made random numbers who were matching our needed output but it gove very inaccurate numbers (only ints no floats as numbers)

in addition: please ping me if there are questions or solutions

Here I will look at yours while I wait for mine.
y Items
x People
z Ranks
Every Person gets a Rank
Each rank that is higher then others gets 5% more items then any previous ranks
You want a formula that divides up the items to fulfill the rank requirement correct?

#

Best way I can think of is Figure out all rank values
ranks = {1.05^0, 1.05^1, 1.05^2, ... 1.05^(z-1)}

then multiple each rank by the number of people in that Rank

#

Then sum those ranks

#

divide number of items by that sum

#

then take that value and mulitply it back into the ranks

#

you each how many item each rank should get

#

if you don't want to go over and whole numbers then you would floor them

#

I'll put example code in python

#
def main() -> None:
    items = 10000
    people = [5, 10, 5]  # 5 rank 0, 10 rank 1, 5 rank 2
    ranks = [1]
    total = 0

    # Auto generate ranks value
    for i in range(len(people) - 1):
        ranks.append(ranks[i] * 1.05)

    # Figure out total we need to divide by to get items worth
    for i in range(len(ranks)):
        total += ranks[i] * people[i]
    item_value = items / total

    # reapply items worth to ranks
    for i in range(len(ranks)):
        ranks[i] = round(ranks[i] * item_value - 0.2)  # Rounding Fix, could just floor

    print("Per Person Items in Ranks: ", ranks)
    print("Total Items in Rank: ", [a * b for a, b in zip(ranks, people)])
    print("Total Items used: ", sum([a * b for a, b in zip(ranks, people)])
)
#

output:

Per Person Items in Ranks:  [476, 500, 524]
Total Items in Rank:  [2380, 5000, 2620]
Total Items used:  10000
#

flooring them gives you 9,985 items of 10k used
