Suppose we want to choose 5 objects, without replacement, from 9 distinct objects. (a) How many ways can this be done, if the order of the choices is not taken into consideration? (b) How many ways can this be done, if the order of the choices is taken into consideration?
The number of ways if the order of the choices is not taken into consideration and taken into consideration will be 126 and 15,120, respectively.
What are permutation and combination?A permutation is an act of correctly arranging things or pieces. Combinations are a method of taking stuff or pieces from an assortment of items or sets in which the order of the items is irrelevant.
Suppose we want to choose 5 objects, without replacement, from 9 distinct objects.
Then the number of ways that this can be done, if the order of the choices is not taken into consideration will be given as,
⁹C₅ = 9! / [(9 - 5)! x 5!]
⁹C₅ = (9 x 8 x 7 x 6 x 5!) / (4 x 3 x 2 x 1 x 5!)
⁹C₅ = 126
Then the number of ways this can be done, if the order of the choices is taken into consideration will be given as,
⁹P₅ = 9! / [(9 - 5)!
⁹P₅ = (9 x 8 x 7 x 6 x 5 x 4!) / 4!
⁹P₅ = 15,120
The number of ways if the order of the choices is not taken into consideration and taken into consideration will be 126 and 15,120, respectively.

Answer:
x^3y^5 + 5x^2y^3 - 4xy^2
Step-by-step explanation:
xy^2 (x^2y^3+5xy-4)
xy^2x^2y^3 + xy^2 x 5xy - 4xy^2
xy^2x^2y^3 = yx^2y^5
xy^2 x 5xy = 5x^2y^3

at a clothing store, levi's jeans are on sale for 40% off. sales tax is 7%. which expression will calculate the total cost of levi jeans with an original price of x?
Given:
Discount = 40%
Sales tax = 7%
To find:
The total cost of levi jeans with an original price of x.
Solution:
Let x be the original price of the jeans. Then the price after 40% discount is
[tex]Price=x-40\%\text{ of }x[/tex]
[tex]Price=x-\dfrac{40}{100}x[/tex]
[tex]Price=x-0.4x[/tex]
[tex]Price=0.6x[/tex]
The price after 7% of sales tax.
[tex]Price=0.6x+7\%\text{ of }0.6x[/tex]
[tex]Price=0.6x+\dfrac{7}{100}\times 0.6x[/tex]
[tex]Price=0.6x+0.042x[/tex]
[tex]Price=0.642x[/tex]
Therefore, the total cost of the levi jeans with an original price of x is represented by the expression 0.642x.

The coordinates of point T are (0,5). The midpoint of ST is (2,-2). Find the coordinates of point S.
The other endpoint is
(Type an ordered pair.)
Answer:
[tex]S = (4,-9)[/tex]
Step-by-step explanation:
Given
[tex]T = (0,5)[/tex]
[tex]Midpoint = (2,-2)[/tex]
Required
Find S
Midpoint is calculated as:
[tex]Midpoint = 0.5(x_1 + x_2,y_1+y_2)[/tex]
So, we have:
[tex](2,-2)= 0.5(0+ x_2,5+y_2)[/tex]
Where x2 and y2 are the coordinates of S
Multiply through by 2
[tex]2 * (2,-2)= 2 * 0.5(0+ x_2,5+y_2)[/tex]
[tex](4,-4)= (0+ x_2,5+y_2)[/tex]
[tex](4,-4)= (x_2,5+y_2)[/tex]
By comparison:
[tex]x_2 = 4[/tex]
[tex]5 + y_2 = -4[/tex]
[tex]y_2 = -4-5[/tex]
[tex]y_2 = -9[/tex]
So:
[tex]S = (4,-9)[/tex]

The mean of five numbers is 4.
The five numbers are 1, 3,5,2 and x.
Find x.
Answer:
9
Step-by-step explanation:
In Order to gain the mean you would follow the formula:
Total Sum of all Numbers added together / Amount of integers.
In this case, you have 5 numbers 1, 3 , 5 , 2 , x .
I know that the overall sum of all your integers added together must equal 20, as 20 / 5 = 4.
1 + 3 + 5 + 2 = 11.
Therefore x must be 9.
1 + 3 + 5 + 2 + 9 = 20
20 / 5 = 4.

Which statement explains how you could use coordinate geometry to prove that quadrilateral ABCD is a rectangle
Answer:
prove that opposite sides are congruent and parallel
Step-by-step explanation:
i took the testtttttt
The statement which explains is Prove that opposite sides are congruent and that the slopes of consecutive sides are opposite reciprocals, the correct option is D.
We are given that;
The quadrilateral ABCD
Now,
A rectangle is a quadrilateral with four right angles, which means that the slopes of consecutive sides are negative inverses of each other.
For example, if the slope of AB is m, then the slope of BC is -1/m.
Also, a rectangle has opposite sides that are equal in length,
which means that the distance between A and B is the same as the distance between C and D, and the distance between B and C is the same as the distance between A and D.
Therefore, by quadrilateral the answer will be prove that opposite sides are congruent and that the slopes of consecutive sides are opposite reciprocals.
