The Collatz conjecture is one of the most famous unsolved mathematical problems, because it's so simple, you can explain it to a

Vinil7 [7]

Hi, you've asked an incomplete question. However, I inferred you need a brief explanation about The Collatz conjecture.

Explanation:

Put simply, what the Collatz conjecture unsolved problem entails is that if any positive number is picked and it is:

An even number (eg 2, 4, 6,...), then if they are divided by 2, the new number gotten should undergo the same process (that is to be divided by 2), it is believed your calculation would finally end up at 1. For example, let's pick the number 6, (6÷2=4; repeating the process 4÷2=1)
An odd number, then if they are multiplied by 3 and 1 is added to the result, it is believed that your calculation would finally end up at 1.

Answer:

a) The general solution θ = nπ±π/6

The all solutions are - π/6 ,π/6 ,5π/6 ,7π/6 ,11π/6 ,13π/6 ...…

b) The solutions in the interval [ 0,2π)

θ = - π/6 ,π/6 , 5π/6 , 7π/6 , 11π/6

Step-by-step explanation:

Step( i):-

Given an equation 2 cos (2θ)-1 =0

2 cos (2θ) = 1

cos(2θ) = 1/2

cos(2θ) = cos (π/3)

Step(ii):-

a)

The general solution of cos θ = cos ∝ is given by

θ = 2nπ±∝

The general solution of cos(2θ) = cos (π/3) is

2θ = 2nπ±π/3

θ = nπ±π/6

Put n=0 θ = ±π/6

Put n =1 θ = π±π/6

θ = π-π/6 = 5π/6

θ = π+π/6 = 7π/6

put n =2

θ = 2π±π/6

θ = 2π-π/6 = 11π/6

θ = 2π+π/6 = 13π/6

The all solutions are - π/6 ,π/6 ,5π/6 ,7π/6 ,11π/6 ,13π/6 ...…

b)

The solutions in the interval [ 0,2π)

θ = - π/6 ,π/6 , 5π/6 , 7π/6 , 11π/6

Final answer:-

a)

The all solutions are - π/6 ,π/6 ,5π/6 ,7π/6 ,11π/6 ,13π/6 ...…

b)

The solutions in the interval [ 0,2π)

θ = - π/6 ,π/6 , 5π/6 , 7π/6 , 11π/6

HELPPP PLEASE !!!!

PolarNik [594]

Answer:

P(B)= 17/20

Step-by-step explanation:

The audience of the magic show is conformed by a total of 120 people, 52 of which are female and 68 are men.

Within the audience there is a school class of 37, of these students, 17 are female and 20 are male.

If a random member of the audience is selected as a volunteer:

Let "A" represent the event that "the selected volunteer is a student of the class"

And "B" the event that "the selected student is female"

You have to calculate the probability of the selected volunteer being female, given that it is a member of the school class.

Symbolically:

P(B|A)

Using the formula of conditional probabilities you can calculate it as:

P(A∩B)= =

As you can see the probability of the event "The volunteer is female given that it was a student of the school class" means that you already know the selected volunteer was a student and only needed to calculate the probability of that student being female.

P(B)= 17/20

I hope this helps
