What is the Permutations?Permutations are different ways of arranging objects in a definite order. It can also be expressed as the rearrangement of items in a linear order of an already ordered set. The symbol nPr is used to denote the number of permutations of n distinct objects, taken r at a time.
Given that,
Number of themes = 3
Number of party places = 2
Number of days = 3
Number of outcomes = 3×2×3
= 18 ways
Therefore, the number of different possible party outcomes does Noah have with all of the given options is 18 ways.

20. Use the piecewise function to evaluate points f(-1), f(2), and f(12).
O A. f(-1) = 3, f(2) = 1, and f(12) = 41
B. f(-1) = 3, f(2) = 6, and f(12) = 41
O C. f(-1) = 2. f(2) = 1, and |(12) = 41
D. f(-1) = 2. f(2) = 6, and f(12) = 41
Answer:
[tex]f(-1) = 3[/tex]
[tex]f(2) = 6[/tex]
[tex]f(12) = 41[/tex]
Step-by-step explanation:
Given
The piece wise function can be split to:-
[tex]f(x) = -2x[/tex] [tex]x\leq -10[/tex]
[tex]f(x) = x + 4[/tex] [tex]-10<x\leq 2[/tex]
[tex]f(x) = 4x - 7[/tex] [tex]x> 2[/tex]
Required
f(-1), f(2) and f(12)
To solve for each of these functions, we first check the range they fall into, then we execute the corresponding function
Solving f(-1)
-1 is within the range of [tex]-10<x\leq 2[/tex]
Hence; we make use of [tex]f(x) = x + 4[/tex]
Substitute -1 for x
[tex]f(-1) = -1 + 4[/tex]
[tex]f(-1) = 3[/tex]
Solving f(2)
2 is within the range of [tex]-10<x\leq 2[/tex]
Hence; we make use of [tex]f(x) = x + 4[/tex]
Substitute 2 for x
[tex]f(2) = 2 + 4[/tex]
[tex]f(2) = 6[/tex]
Solving f(12)
12 is within the range of [tex]x> 2[/tex]
Hence; we make use of [tex]f(x) = 4x - 7[/tex]
Substitute 12 for x
[tex]f(12) = 4(12) - 7[/tex]
[tex]f(12) = 48 - 7[/tex]
[tex]f(12) = 41[/tex]
Jose receives a monthly salary of $2,870 his annual salary is raised by 8% what is his new annual salary
Answer:
The answer is $37195.20
Step-by-step explanation:
The annual salary would be 12 times the monthly salary. Therefore, if the monthly salary is 2,870 the annual (yearly) salary would be 12 times as much. Which would result in 34,440. Then you would have to find 8% percent of 34,440 which is 2,755.20. Finally, just add the two numbers which will get you 37195.20.

Describe any patterns you notice. Are the two expressions ever equal? Can one be greater than the other?
Answer:
Both expressions are equal. One expression cannot be greater than the others.
Step-by-step explanation:
The given expressions are:
A: (x + y)
B: (x) + (y)
Let x = a and y = bA: (a+b) = a+b
B: (a)+(b) = a+b
Let x = -a and y = -bA: (-a+ (-b)) = -a-b
B: (-a)+(-b) = -a-b
Let x = a and y = -bA: (a+(-b)) = a-b
B: (a)+(-b) = a-b
Let x = -a and y = bA: ((-a)+b) = -a+b
B: (-a)+(b) = -a+b
We can see the pattern that both expressions are always equal to each other, no matter what value of x and y you plug in. One expression cannot be greater than the other

A lottery ticket costs $5. You pick 3 two-digit numbers (anything from 00 to 99) in order. If you match the first number only, you win $200. If you match the first two numbers and not the third, you win $5000. If you match all three numbers, you win $100,000. In two or more complete sentences, explain whether or not the game is fair. In your explanation, include all necessary calculations.
Answer:
00 to 99 are 100 numbers.
If you match the first number only, you win $200. The Probability for this is 1/100.
If you match the first two numbers and not the third, you win $5000. The Probability for this is 1/50.
If you match all three numbers, you win $100,000. The Probability for this is 3/100.
And, If you are a customer, You will think is fair for you.
But if you are the lottery tickets company, you will think is not fair for you.
It depends who you are.
the game isn't fair because 100,000/3=3333 1/3, so each number should be worth $3333.3333...... dollars but you can't really give 1/3 dollars so the game is impossible to be fair. Also, if you match the first two numbers you apparently get $5000. That's also not fair because each number is worth $50 dollars more than if you get the first number matched. So, the game isn't fair but it will be pretty much impossible to be fair.
Find the measures of all four angles if 3·(m∠1+m∠3) = m∠2+m∠4.
Answer:
Step-by-step explanation:
m∠1=m∠3
m∠2=m∠4
3*(m∠1+m∠3)=m∠2+m∠4
3*(m∠1+m∠1)=m∠2+m∠2
3×2 m∠1=2 m∠2
m∠2=3 m∠1
now m∠1+m∠2=180°
m∠1+3 m ∠1=180
4 m∠1=180
m∠1=180/4=45°
m∠3=45°
m∠2=180-m∠1=180-45=135°
m∠4=135°
Find the measures of the angles of the ∆ABC if m∠A : m∠B : m∠C = 2:3:4.
Answer:
m∠A = 2x = 2*20 = 40
m∠B = 3x = 3*20 = 60
m∠C= 4x = = 4*20 = 80
Step-by-step explanation:
we know sum of angles of triangle is 180 degrees
given
m∠A : m∠B : m∠C = 2:3:4
let the angle be
m∠A = 2x
m∠B = 3x
m∠C= 4x
we have taken such angle by applying rule of indices where
a:b:c = ax:bx:cx
which means that if we multiply all term of ratio by same number ratio remains same
thus,
2x+3x+4x = 180
9x = 180
x = 180/9 = 20
Thus,
m∠A = 2x = 2*20 = 40
m∠B = 3x = 3*20 = 60
m∠C= 4x = = 4*20 = 80
If f(x) = 1/6 x-8, then f^-1(x)=
Answer:
f^-1(x) is 6x + 48
f(x) = 1/6x - 8
To find f^-1(x) equate f(x) to y
That's
f(x) = y
y = 1/6x - 8
Next interchange the terms
We have
x = 1/6y - 8
Make y the subject
Multiply through by 6
We have
6x = y - 48
y = 6x + 48
Therefore f^-1(x) is 6x + 48

of the following statements is true about the sample?
It is not a valid sample because it is only a short study
It is a valid sample because money was offered to participants
It is a valid sample because the first five people were selected to participate
It is not a valid sample because it is not a random sample of the population
Answer:
It's a valid sample because the first five people were selected to participate.
Step-by-step explanation:
True because random people who saw the advertisement responded. By chance, not every person who saw the advertisement answered, therefore it was random, but it would be more random if he decided to reject the second, fourth, sixth, and eighth person, and only the first, third, fifth, seventh, and ninth were chosen.

Required: Simplify
[tex](x - 1 - \sqrt{2})(x - 1 + \sqrt{2})[/tex]
Group the expression above
[tex]((x - 1) - \sqrt{2})((x - 1) + \sqrt{2})[/tex] -------- Expression 1
The expression can be expanded using difference of two squares;
[tex](a - b)(a + b) = a^2 - b^2[/tex]
By comparison, Expression 1 can be rewritten as
[tex](x - 1)^2 - (\sqrt{2})^2[/tex]
Open both brackets
[tex](x - 1)(x - 1) - (\sqrt{2})(\sqrt{2})[/tex]
Expand the above expression
[tex](x(x - 1) -1(x - 1)) - 2[/tex]
[tex](x^2 - x -x + 1)- 2[/tex]
[tex](x^2 - 2x + 1)- 2[/tex]
Remove bracket
[tex]x^2 - 2x + 1- 2[/tex]
[tex]x^2 - 2x - 1[/tex]
Hence,
If
[tex](x - 1 - \sqrt{2})(x - 1 + \sqrt{2})[/tex] is a factor of p(x)
Then
[tex]x^2 - 2x - 1[/tex] is a factor of p(x)

Part 1: [tex]2l+2w=34[/tex] Part 2: 10.5 Units
Step-by-step explanation:
We can find perimeter of a rectangle using formula [tex]2l+2w=P[/tex]. We are given [tex]w[/tex], which is 6.5. Put this into the equation.
[tex]2l+2(6.5)=342l+13=34\\2l=21\\l=10.5[/tex]
So, length(l) of the rectangle is 10.5 units.
Answer:
10.5
Step-by-step explanation:
The perimeter of rectangles is calculated by adding all lengths together
34 units = length + length + width +width
since width is given as 6.5 units
2l + 2 × 6.5 = 34 (l : length)
2l + 13 = 34
2l = 21
l = 10.5
