Suppose we want to choose 5 colors, without replacement, from 18 distinct colors.
(a) If the order of the choices does not matter, how many ways can this be done?
(b) If the order of the choices matters, how many ways can this be done?
Considering the definition of permutation and combination:
the number of ways of choosing 5 colors from 18 distinct colors (the order doesn't matter) is 8,568.the number of ways of choosing 5 colors from 18 distinct colors (the order of choices matters) is 1,028,160.Definition of PermutationPermutation is placing elements in different positions. So, permutations of m elements in n positions are called the different ways in which the m elements can be arranged occupying only the n positions.
In other words, permutations (or Permutations without repetition) are ways of grouping elements of a set in which:
take all the elements of a set.the elements of the set are not repeated.order matters.To obtain the total of ways in which m elements can be placed in n positions, the following expression is used:
[tex]mPn=\frac{m!}{(m-n)!}[/tex]
where "!" indicates the factorial of a positive integer, which is defined as the product of all natural numbers before or equal to it.
Definition of combinationCombinations of m elements taken from n to n (m≥n) are called all the possible groupings that can be made with the m elements in such a way that not all the elements enter; the order does not matter and the elements are not repeated.
To calculate the number of combinations, the following formula is applied:
[tex]C=\frac{m!}{n!(m-n)!}[/tex]
This caseIn this case, you know we want to choose 5 colors, without replacement, from 18 distinct colors. This is:
We want to choose 4 colors: n= 5The total number of distinct colors: m= 18(a) If the order of the choices is not taken into consideration, you use a combination as follow:
[tex]C=\frac{18!}{5!(18-5)!}[/tex]
Solving:
[tex]C=\frac{18!}{5!13!}[/tex]
C= 8,568
Finally, the number of ways of choosing 5 colors from 18 distinct colors (the order doesn't matter) is 8,568.
(b) If the order of the choices matters, you use a permutation as follow:
[tex]18P5=\frac{18!}{(18-5)!}[/tex]
Solving:
[tex]18P5=\frac{18!}{13!}[/tex]
18P5= 1,028,160
Finally, the number of ways of choosing 5 colors from 18 distinct colors (the order of choices matters) is 1,028,160.

Passenger trains leave the station every
40 minutes. Freight trains leave every
30 minutes. If a passenger train and a
freight train just left at the same time, how
long will it be before one of each train
departs at the same time again?
When Passenger trains leave the station every 40 minutes and Freight trains leave every 30 minutes, If a passenger train and a freight train just left at the same time, then it will take 120 minutes for one of each train departs at the same time again
Given,
The passenger trains leave the station every 40 minutes
Freight trains leave every 30 minutes
We have to find the LCM
Prime factorization
30=2×3×5
40=2×2×2×5
LCM(30,40)= 2×2×2×3×5=120
Hence, when Passenger trains leave the station every 40 minutes and Freight trains leave every 30 minutes, If a passenger train and a freight train just left at the same time, then it will take 120 minutes for one of each train departs at the same time again.

Cost price of an item is Rs 600. If the selling price is Rs 780, then the profit percent is
Answer:
Profit percentage=30%
Step-by-step explanation:
The profit percentage=profit/cost price×100%
but we can calculate profit as=selling price-cost price
profit=Rs780-Rs600=Rs180
Now substitute the profit value into the formula
Profit percentage=Rs180/Rs600×100%=30%
C.P of an item= Rs.600
S.P of an item = Rs. 780
Profit = SP- CP
= Rs. 780- Rs.600
=Rs.180
Now, profit percent= profit÷ CP × 100%
= 180 ÷ 600 × 100%
=30%

Lynne needs to borrow $9500 for cosmetic surgery she obtains a loan from her grandmother for 24 months at a simple interest rate of 9.3% what is the loans future value?
Answer:
$11267
Step-by-step explanation:
Loan Future value = amount borrowed + interest
Amount borrowed = 9500
Interest = Principal * Rate * Time/100
Interest = 9500*9.3 * 2/100
Interest = 95*9.3 * 2
Interest = $1767
Loan Future amount = 9500 + 1767
Loan Future amount = $11267

In the figure, the angle x° is an alternate angle with angle 54° so the measure of angle x° is 54°.
We have,
From the figure,
Line m and line n are parallel.
Line t is the transversal line.
Now,
Alternate angles are a pair of angles that are formed when a transversal (a line that crosses two other lines) intersects two parallel lines.
When this happens, the alternate angles are on opposite sides of the transversal and are congruent, which means they have the same measure.
Angle 54° and angle x° are alternate angles.
Alternate angles are equal.
So,
x° = 54°
Thus,
The measure of angle x° in the figure is 54°.

A kite is currently flying at an altitude of 9 meters above the ground.
and, the angle of elevation from the ground to the kite is 32 degrees.
To find the length of the kite string to the nearest meter.
Now, According to the question:
Let the length of the kite string be x m.
From the diagram, the length of the kite string x m is hypothesis
The altitude is 9 m is opposite
and, horizontal line is adjacent.
Formula is:
Sin θ = opposite / hypotenuse
where Sinθ = 32 degree
opposite = 9 m
Hypotenuse = x m
Hence, Sin 32 = 9/x
x = 9/ sin 32 , and Sin 32 degree = 0.5299(approx.)
x = 9/ 0.5299
x = 16. 984 (approx.)
