Answer:
median:11
mode:11
mean:11.143
range:
Step-by-step explanation:
median is the middle number so you first arrange the numbers in an ascending order after rounding off each number. Then you're gonna cancel one number from the left and one from the right until they remain two numbers then you add them and divide by 2 to get 11
I'm not sure about mode coz it's the most repeated number
mean is where you add all numbers and divide them by the total amount of numbers.

For each of the following polynomials given a power function that best represents the end behavior of the polynomial. Draw the arrows.
Answers
Answer:
the answer is the 3rd to the 4th power and
The end behavior of the polynomial y=-4x+8x-21'+3 is y = -4x^3.
What is degree of a polynomial?Degree of a polynomial is the highest power that its terms pertain (for multi-variables, the power of term is addition of power of variables in that term).
Thus, in the degree of the polynomial is 3 as the highest power in its terms is 3.
(power and exponent are same thing)
We are given that;
The functions (a) 1=3x-2x+12
(b) 1-10-8.x2
(c) y=6r-4r+x-120
(d) y=-3x+2x-4x+7
(e) y=5x+2x2
(f) y=-4x+8x-21'+3
Now,
To find the power function that best represents the end behavior of a polynomial, we need to look at the leading term (the term with the highest degree) of the polynomial.
(a) The leading term of this polynomial is 3x. So the power function that best represents its end behavior is y = 3x.
(b) The leading term of this polynomial is -8x^2. So the power function that best represents its end behavior is y = -8x^2.
(c) The leading term of this polynomial is 6r. So the power function that best represents its end behavior is y = 6r.
(d) The leading term of this polynomial is -3x^3. So the power function that best represents its end behavior is y = -3x^3.
(e) The leading term of this polynomial is 2x^2. So the power function that best represents its end behavior is y = 2x^2.
(f) The leading term of this polynomial is -4x^3. So the power function that best represents its end behavior is y = -4x^3.
Therefore, by polynomials the answer will be y = -4x^3.

Answers
The expected foot length of an adult male who is 1.8 m tall is 30.8 cm.
How to illustrate the information?Based on the information given, Jerry surveyed adult males to study the relationship between their high and the length of their footwear both are measured in centimeters and he found the equation y equals 75 + 3.4 x.
This will be illustrated as:
y = 75 + 3.4x..
y = 1.8m = 180
Therefore, y = 75 + 3.4x.
180= 75 + 3.4x
180 = 75 + 3.4x
Collect like terms
3.4x = 180 - 75
3.4x = 105.
Divide
x = 105 / 3.4
x = 30.8 cm
Therefore, the expected foot length of an adult male who is 1.8 m tall is 30.8 cm.

Answers
The set of points on this graph is a relation but not a function
We know that every function can be a relation but every relation cannot be a function.
A relation means the connection between the input and the output.
A function means that for every input there should only be one output.
Here, we have the data as:
(2,5), (1,2), (3,4), (3, 1), (6,5) and (5,3)
We can say that it is a relation as for every input, there is an output.
But, it is not a function.
This is because the input 3 has 2 outputs as 1 and 4 which is not possible in a function.
Therefore, the set of points on this graph is a relation but not a function.

What are the domain and range of the function f(x) = x^2 + 5x + 4/ x+4
Answers
This is just a linear equation, then the domain is the set of all real numbers and the range is the set of all real numbers.
How to find the domain and range of the given function?Here we have the function:
f(x) = (x^2 + 5x + 4)/(x + 4)
The numerator can be rewritten if we find the zeros:
x = (-5 ± √( 5^2 - 4*1*4))/(2*1)
x = (-5 ± 3)/2
Then the zeros are:
x = (-5 - 3)/2 = - 4
x = (-5 + 3)/2 = -1
So the numerator can be rewritten to (x + 4)*(x + 1)
And the function is rewritten to:
f(x) = (x^2 + 5x + 4)/(x + 4) = (x + 4)*(x + 1)/(x + 4) = (x + 1)
This is just a linear equation, then the domain is the set of all real numbers and the range is the set of all real numbers.

Pls help BD bisects LABC. Find m LABD, m m LABC = (25x + 34) °
Answers
Answer: ABD=67 degrees
CBD=67 degrees
ABC=134 degrees
Step-by-step explanation:
ABC=ABD+CBD
25x+34=ABD+11x+23
14x+34=ABD+23
ABD=14x+11
ABD=CBD ==> Bisected angles are equal to each other since angle ABC is divided into two equal angles when bisected.
14x+11=11x+23
3x+11=23
3x=12
x=4
ABD=14x+11
ABD=14(4)+11
ABD=56+11
ABD=67 degrees
CBD=11x+23
CBD=11(4)+23
CBD=44+23
CBD=67 degrees
ABC=25x+34
ABC=25(4)+34
ABC=100+34
ABC=134 degrees
Answer:
∠ ABD = 67° , ∠ CBD = 67° , ∠ ABC = 134°
Step-by-step explanation:
since BD bisects ∠ ABC , then
∠ ABD = ∠ CBD = 11x + 23
∠ ABC = ∠ ABD + ∠ CBD ( substitute values )
25x + 34 = 11x + 23 + 11x + 23
25x + 34 = 22x + 46 ( subtract 22x from both sides )
3x + 34 = 46 ( subtract 34 from both sides )
3x = 12 ( divide both sides by 3 )
x = 4
Then
∠ ABD = 11x + 23 = 11(4) + 23 = 44 + 23 = 67°
∠ CBD = ∠ ABD = 67°
∠ ABC = 25x + 34 = 25(4) + 34 = 100 + 34 = 134°

Solve for x
Subtract 40 from both sides to isolate x
2x + 40 - 40 = 180 - 40
2x = 140
Divide both sides by 2 to solve for x
2/2 x = 140/2
x = 70
Now check your work

HELP ASAP
Answers
By solving a system of equations, we can see that each geranium costs 3 dollars.
What is the cost of one geranium?
First, let's define the two variables:
x = price of one rose bush.
y = price of one geranium
Now, with the information on the problem we can write two equations, thus, we will have a system of equations:
$122 = 14*x + 8*y
$120 = 12*x + 12*y
We want to solve that system, if we isolate x on the first equation we will get:
x = ($122 - 8y)/14
Now we can replace this on the other equation:
$120 = 12*($122 - 8y)/14 + 12*y
Now we can solve this for y.
14*$120 = 12*($122 - 8y) + 12*14*y
$1,680 = $1,464 + 72y
($1,680 - $1,464 )/72 = y = $3
Each geranium costs 3 dollars.
