Hello everyone, my name is Alessandro and I am trying to find a solution to the following statistic problem: "Assuming a standard deviation of 0.15 and approximately normal distribution, find a 95% confidence interval for the mean of a given effect caused by a treatment. A random sample of 75 patients has an average increase in iron uptake of 3.1%. What does the result means?" Does anyone could help please? Thank you in advance 😄

@harsh acorn How many total ways are there to roll two dice?
harsh acorn
36
oak chasm
So, 4/36
Remember, those four are pairs.
There are four pairs you want.
There are 36 pairs total.
harsh acorn
so it is not (4/6)*(4/6)
zenith swift
What is Remainder Theoram ?
oak chasm
@zenith swift Sorry, the channel is busy.
@harsh acorn Multiply that out.
You get 16/36, right?
harsh acorn
yep
oak chasm
So, that would be 16 pairs/36 pairs, right?
harsh acorn
yes
harsh acorn
oooh
i understand now
2piR= length of wire
2x+2y=length of wire
x+y=length of wire/2
and i choose numbers that they are really close (which is 26 and 25)
and answer is 650?
want to check am i doing right

If all distinct, then:
Total number of arrangements would be P(8,8) = 8! = 40320
If you group the boys, then 7!*2! = 10080
If you group the girls, then 3!*6! = 4320 -
If boys are alike and girls are alike, then:
Total number of arrangements would be P(8,8) / P(2,2)P(6,6) = 8! / ((2!)(6!)) = 28
If you group the alike boys, then 7! / 6! = 7
If you group the alike girls, then 3! / 2! = 3

isnt there any magical formula for that
well how do you input the grid into the magical formula

and substract the paths you dont ahve
woeful pulsar
and substract the paths you dont ahve
that's more tedious than the systematic approach for each point

unfortunately you wouldn't be given that in mathematics
woeful pulsar
count how many paths there are to nearby vertices
there is 1 path from A to A
yay
harsh acorn
woeful pulsar
now pick a nearby point and count paths to it
there is 1 path from A to all the points in the same column as A
harsh acorn
for corners there are 1
woeful pulsar
this is one path from A to all the points in the same row as A
so far we have this
how many ways to get to the circled point?
woeful pulsar
wrong
forest sun
thank you for the help @lapis harness
woeful pulsar
Let's be systematic and continue from here
harsh acorn
harsh acorn
you are right
woeful pulsar
try this
notice there's one way to get from the left and 2 ways to get from below
harsh acorn
3 way
harsh acorn
5?
woeful pulsar
there are 3 ways to get from the left
woeful pulsar
earlier you only drew two ways to get from the left
that means you are missing something
woeful pulsar
so 6=3+3
so in general you can add the number of paths on the left and the number of paths below
@harsh acorn can you complete it?
harsh acorn
i guess yes
38?
sorry for bad writing
my hand vibrates a bit much
oh BASIC OPERATION ERROR LMAO
woeful pulsar
lol
harsh acorn
sssshh
anyway i understant it now
so in general you can add the number of paths on the left and the number of paths below- good to know that lol

how can i find the number in the green square? @woeful pulsar can u say to me please
woeful pulsar
how can i find the number in the green square? <@!104219409991626752> can u say...
well if there is a left path and a path below to come from then we can add them
here we only can come from below
so there's really nothing to add
woeful pulsar
so it is 6?
let's see the resulting diagram you have?

then take a break.

notice how any factor of 2040 must be a number of the form $2^m 3^n 5^p 17^q$ where $m \in {0,1,2,3}$ and $n,p,q \in {0,1}$

vale wigeon
in other words any factor of 2040 must be the product of exactly one number from each of these lists:
[1, 2, 4, 8]
[1, 3]
[1, 5]
[1, 17]
this is a little tricky to explain so i can try to give a simpler example if you want

A computer company just manufactured 1200 new tablets. The quality control team randomly chose fifty tablets to test their USB ports. They discovered that 6 of the ports do not work properly. How many tablets should the company expect to have this same issue?
what is answerrr idk this
alpine sable
I believe they find the ratio of defective tablets out of 50 and then make that same ratio with 1200 tablets
But that seems stupid
radiant pendant
whats the percent tho
alpine sable
Like 6 out of 50 are defective so that means 12 per cent
My guess is they want 12% of the total too

fading zephyr
the marks on the sides of the base presumably mean it is an equilateral triangle, with all sides equal to 8
you can split such triangle in half, getting a side length of 4 on one side, a hypotenuse of 8, and the remaining side is the height
furthermore, this triangle is a 30 60 90 special triangle
for which the sides have scale factors of 1, sqrt(3), and 2

i didn't even notice the bounds changing lol
glass lichen
Notice the changed bounds in the 2nd line
fading zephyr
then combine them as moshill says
wise jewel
@fading zephyr wdym by "for which the sides have scale factors of 1, sqrt(3), and 2" ?
fading zephyr
i mean there is a prototype 30 60 90 triangle for which the sides are 1, sqrt(3), and 2
and every other triangle with the same angles is similar to it, in the sense that the sides are just scaled up by some constant
like in your case, scaled up by 4
giving you sides 4*1, 4sqrt(3), and 4 * 2
you should have seen this early on in geometry/trigonometry

I know pi notation but not how you'd find the product up to 2018 by hand
That's a huge number to square
harsh swallow
not multiplying by itself but how to deal with a product like this
harsh swallow
i haven't dealt with something like this either
harsh acorn
when i calculate it it gives simple answer

how can i find this
ocean sealBOT
real sinew
Well theres the answer but who knows how you'd find that answer while showing work? Lol
real sinew
Ohh
harsh acorn
anyway
glass lichen
You'd do a couple small examples to develop a pattern
then show that pattern is true
muted raft
yes
harsh acorn
well patters was given and i did write product by myself ( it is old question i am resolving it and still failing :d)
after writing product i stuck
glass lichen
If you take only the even terms in the partial products you get $\frac{3}{4},\frac{5}{8},\frac{7}{12},...$
ocean sealBOT
moshill1
harsh acorn
i want to know that how did he get these (a-1)(b+1)...
glass lichen
so for the even terms, $P_{2x}=\frac{2x+1}{4x}, x\in\mathbb{N}$
so when x= 2018/2, you get P_(2018)
Then it's just a quick induction to show the pattern always holds
ocean sealBOT
moshill1
harsh acorn
still confused
strong furnace
:/
glass lichen
$\prod_{n=2}^N\frac{n^2-1}{n^2}$ compute for N in {2,3,4,5...,7} and you'll see a pattern
ocean sealBOT
moshill1
harsh acorn
oooh i understand now
glass lichen
And since 2018 is even, we likely want to look at the even partial products
so doing N=2,4,6 (8 if you need to), you get the fractions I already listed
so when $N=2x,x\in\mathbb{N}$, we propose that $P_{2x}=\frac{2x+1}{4x}$
ocean sealBOT

is this true?
does it look true?

not to me
woeful pulsar
then try coming up with a counterexample
alpine sable
i did try with A = {1, 2}, B = {3, 4} and it doesnt seem to hold
pale cargo
is 4184000 in jouls or Kg TNT
alpine sable
i did try with A = {1, 2}, B = {3, 4} and it doesnt seem to hold
It holds I guess
Does it? then P(AUB) = P({1, 2, 3, 4}) = {phi, {1}, {2}, ..., {1,2,3,4}}
but P(A) = P({1, 2}) = {phi, {1}, {2}, {1,2}}. similarly P(B) = {phi, {3}, {4}, {3, 4}}
then their intersection is just phi
Oh ok
I thought it was union
alpine sable
but P(A) = P({1, 2}) = {phi, {1}, {2}, {1,2}}. similarly P(B) = {phi, {3}, {4},...
what i did here is it right? ^
that and the prev one
Yup
we are asked to prove it. its an assignment so presumable it should be true so im confused
Um are u sure it's he question
I guess this maybe true
alpine sable
Well give a counterexample lol
ikr lol thatll do
near portal
P(AUB) isnt equal to P(A)U P(B) except if A and B have nothing in common

@harsh acorn Find the last digit of 4, 16, etc.
They will eventually cycle.
So, what's the sequence?
Sorry, 1, 4, 16, 64, 256, ...
What are the last digits of the sequence?
1, 4, 6, 4, 6, ...
So, we have a cycle.
There are two elements in the cycle.
The number of elements in the non-1 part of the sum is even.
So, if you add 4 + 6, you get 10, which has last digit 0.
So, each cycle sums to 0.
So, you have an integer multiple of the cycle length (2018)
This is 1009 times 0, which is 0, which has last digit 0.
So, add the initial 1 to 0, you get 1, which has last digit 1.
Which is your answer.

but there is no value for P. its just ln(n) which i cant really compare to 1
You can pick your fav value of p (which is greater than 1) because the inequality will be true from a point and onwards
Whether a series diverge or converge only depends on the tail
So for example compare with 1/(n^2)
solid lion
oh i see, so i could use a number like 3 and have n^ln(3)
noble sinew
Sure but then you still need to say ln(3)>...>1 to use p-series

It is: 1/(s)(2s^2 +10)
yep
I know I would set it up as something like 1 = A(2s^2 + 10) + (Bs+C)(s)
toxic rose
yes
fading rover
But im having trouble finding B and C
I can get A with s = 0
It ends up being A = 1/10
toxic rose
Im solving it one moment
mellow panther
k
fading rover
sorry
toxic rose
Ok, so you get A=1/10, then you plug that in and simplify here and there. Then, you get 9 = (s^2)/5 + Bs^2 +C, with this, you then use s=1 and get B+C = 9- (1/5), then you try with s=-1, in which you get B-C = 9 - (1/5), so, you have that B-C = B+C, so, -C=C, and this can only happen if C= 0, afterwards, you substitute it back in and get that B = 9 - 1/5
fading rover
Im not sure why you set it equivalent to 9 or why the second s term was removed from Bs^2 + C
I got the entire thing equivalent to 0 when solving for A and plugging it back in
0 = 1/5s^2 + bs^2 + cs
toxic rose
1 = (2s^2 +10)/10 + Bs^2 +Cs
Then, 1 = 2s^2/10 +10/10 +Bs^2 +C
Thus, 1 = s^2/10 +1 +Bs^2 +C
And you get to (excuse my mistake earlier, it isn't 9) 0 = s^2/10 +Bs^2 + Cs
Then, let s = 1, 0 = 1/10 + B +C => -1/10 = B + C
Then, let s = -1, 0 = 1/10 + B + C => -1/10 = B - C,
So, you get that B+C = B-C => C = -C which can only happen if C = 0. Then plug that in and you get that B = -1/10

Why are we allowed to set s = 1 arbitrarily
If nothing is removed, or does it not matter
Could I technically plug in 1,000,000 and still get a valid answer

the sides are multiples of pythagorean triplet (3,4,5) you can use that to skip the calculation in this case

well, do you know the relationships between sin, tan, cos and the sides of the right angled triangle?
bronze trench
yes
hazy sphinx
then which part specifically is the problem?
hazy sphinx
well, it depends on whichever angle you're using; whichever angle you use, the one below it is the base and the one vertical to it is the perpendicular
hazy sphinx
no, but the denominator is correct
the side opposite to the angle is the perpendicular
the side touching the angle, but isn't the hypotenuese is the base

i don’t know it
wide coral
i don’t know it
well a line with a slope of zero would be a horizontal line. A line with a slope of -3 can be drawn be starting at a point and then drawing another point down 3 inches and to the right 1 inch.
in this example the red line has a slope of -3 and the blue line has a slope of 0
alpine sable
so they bisect
wide coral
so they bisect
They meet at the corners. We know it's a quadrilateral and so your final shape should look something like one of these
wide coral
but what properties does it show
first you'll need to figure out what kind of quadrilateral it is. different shapes will have different properties. And then you can test the properties one by one
alpine sable
I have no other info though
wary maple
It is said diagonals are congruent
alpine sable
for number one?
wide coral
I have no other info though
let's narrow it down. We know it has 2 sides that are horizontal (zero slope). so what shapes are possible? (im looking at number 2)
wary maple
So we can say that the side ratio should be equal to diagonal ratio

number 2 is a parallelogram, yes 👍

Why not number 1
alpine sable
so then since it’s a plelgram what can we say
wary maple
It is also a class of parallelogram
wary maple
For no.1 all are corrects
wary maple
I m telling you about 1st part
In 2nd part since a slope is given you can consider it a parallelogram
But not a trapezium

which one

Q4
ionic jewel
assume the total distance is some variable x
260 + 35% of x = x
do you see where I got this?
shrewd violet
Er my little bro yr4 lol he dont get algebra
ionic jewel
okay
how about this then
100% - 35% = 65%
you know that 260 was 65% of the way there

by the looks of it your little brother has 65% of something = 260 figured out in his head , he is just unable to express it I guess

yes, and you know m<5 = 50 deg
so then start applying angle rules to solve for the other 7 angles

Isabel's family is moving. They will rent a large, enclosed trailer and some moving boxes. The trailer and each moving box have dimensions as shown in the drawing. The dimensions of the trailer are internal dimensions.
Examine how many moving boxes can be in the trailer at most. You must justify your answer with calculation and one or more sketches showing how the family can place the moving boxes in the trailer.
@glass lichen 48 is wrong
