The smallest positive integer n so that you can avoid ever having the exact same group of three members over all 365 days is; 11
How to solve probability combination?
if we have n people and we want to do groups of 5, the total number of different combinations is:
ⁿC₅ = n!/((n - 5)!5!)
By using the Brute force method, we have;
If n = 5,
c = 5,
Thus;
C₅ = 5
If n = 6,
c = 6,
Thus;
C₅ = 6
If n = 7,
c = 7,
Thus
C₅ = 21
If n = 8,
c = 8,
Then;
C₅ = 56
Now, If n = 9,
C = 9!/((9 - 5)!5!)
C = 126
We want to find the smallest n such that c > 365. Thus, C = 126 is too small.
Let's try n = 11;
C = 11!/(6! * 5!) = 462
This is greater than 365 and so we need at least 11 members in the club.

Through the use of a light microscope it is possible to observe in multicellular organisms different types of cells and organelle features, and in general, they are all very small.
What are multicellular organisms?They are all those forms of life whose bodies are composed of a diversity of cells organized, hierarchical, at the cellular level through organelles that are specialized cell differentiations.
The cells that make up these organisms have different shapes and sizes and, in general, they are all very small, so to see them it's needed a light microscope, an instrument that increases many times the size of samples.
Therefore, we can conclude that through the use of a light microscope it is possible to observe in multicellular organisms different types of cells and organelle features, and in general, they are all very small.

The decomposition of n2o5 can be described by the equation 2n2o5(soln)⟶4no2(soln)+o2(g) consider the data in the table for the reaction at 45 ∘c in carbon tetrachloride solution.
The reaction rate between 0 -195 seconds for the decomposition of N2O5 is 0.0006 M/s.
What is the rate of a reaction?The rate of reaction can be estimated in terms of the consumption of the reactants in the reaction.
From the given information, the equation N2O5 has been the reactant that has been used in 2 moles.
The rate of the reaction is expressed as:
[tex]\mathbf{Reaction \ rate = -\dfrac{1}{2} \times \dfrac{dN_2O_5}{dt}}[/tex]
The reaction rate for a time interval between (0 - 195) sec is expressed as follows:
[tex]\mathbf{Reaction rate = -\dfrac{1}{2} \times \dfrac{1.86556-2.10195}{195s - 0s}}[/tex]
[tex]\mathbf{Reaction \ rate = -\dfrac{1}{2} \times \dfrac{-0.23639}{195s}}[/tex]

You work every saturday from 9:00 a.m. to 5:00 p.m. find the measure of the angle generated by the hour hand of a clock during this time in both degrees and radians. compare this angle with the angle generated by the minute hand from 9:00 a.m. to 5:00 p.m.
The angle generated by the hour hand measures -270° or -4.71 radians, and we will see that the angle generated by the minute hand is 12 times the one generated by the hour hand.
How to get the angle generated?Remember that in a complete rotation we have an angle of 360°, and in a complete rotation we have 12 hours, then there is a relation:
12 hours = 360°
1 hour = 360°/12 = 30°
From 9:00 a.m to 5:00 p.m. there are 9 hours, so the angle that the hour hand does is:
A = 9*(30°) = -270°
(the negative sign is because this angle is measured clockwise)
Now we can write this in radians, remember that:
3.14 radians = 180°
Then:
1 = (3.14 rad/180°)
Then:
270° = -270°*(3.14 rad/180°) = -4.71 rad
What is the angle generated by the minute hand?Each hour that passes, the minute hand does a complete revolution. Then in 9 hours, the minute hand does an angle of:
A = 9*(-360°) = -3,240°
To compare this angle to the one generated by the minute hand we take the quotient:
-3,240°/-270° = 12
So this angle generated by the minute hand is 12 times the one generated by the hour hand.

How many ways can you listen to 3 songs from a cd that has 12 selections?
Taking into account the definition of permutation, there are 1320 ways you can listen to 3 songs from a cd that has 12 selections.
What is permutationPermutations refer to the action of arranging all the members of a set in some kind of order or sequence. This means that if a set is already ordered, the process of rearranging its elements is called permutation.
In other words, permutations of m elements in n positions are the different ways in which the m elements can be arranged occupying only the n positions.
In this case, the elements are not repeated, since if they are repeated or equal to each other, exchanging them does not generate a new permutation. And the order does matter, since the exchange between two different elements generates a new permutation
To obtain the total of ways in which m elements can be placed in n positions, the expression is used:
[tex]P=\frac{m!}{(m-n)!}[/tex]
The sign ! indicates the factorial function, which indicates that all positive integers between the number that appears in the formula and the number 1 must be multiplied.
Number of ways you can listen to 3 songsThe order in which songs are listening is important as there is no plan to listen to the same song twice. So, the permutation can be applied.
Being:
m=12n=3and replacing in the expression for permutation, you get:
[tex]P=\frac{12!}{(12-3)!}[/tex]
[tex]P=\frac{12!}{9!}[/tex]
[tex]P=\frac{479001600}{362880}[/tex]
P= 1320
