Media
Explicación paso a paso:
Primero debemos saber que cambiar el valor de 6 a 7 no puede cambiar la mediana y la moda de los datos, ya que la moda es el valor que más ocurre, que es 3, mientras que la mediana es el valor tq en el medio después del reordenamiento.
La única medida de tendencia que cambiará es la media (datos promedio)
Vamos a revisar
Encuentra la media de dos datos originales
Media = 3, + 4, + 6 + 3, + 5 + 5 + 6 + 3 + 4/9
Tamaño de muestra = 9
Media = 39/9
Media = 4,33
Si uno de los 6 se reemplaza por 7, la media se convierte en
Media = 3, + 4, + 6 + 3, + 5 + 5 + 7 + 3 + 4/9
Tamaño de muestra = 9
Media = 40/9
Media = 4,44
Podemos ver que cambió el valor medio. Por tanto, la respuesta correcta es la media.
Teniendo en cuenta la definición de media, mediana y moda, la media aritmética es la única medida de tendencia central que cambia.
Media aritméticaLa media (también llamada promedio o media aritmética) de un conjunto de datos es una medida de posición central cuyo valor se obtiene al dividir la suma de todos los números entre la cantidad de ellos. Entonces, en este caso, el promedio de las notas obtenidas por Esteban se calcula como:
[tex]media=\frac{3+4+6+3+5+5+6+3+4}{9}[/tex]
Resolviendo:
media= 4,33
La media aritmética de las notas de Esteban es 4,33.
Si de las notas de Esteban se cambia un 6 por un 7, se obtiene la serie de notas:
3, 4, 7, 3, 5, 5, 6, 3, 4
Entonces, la media aritmética de las notas obtenidas por Esteban se calcula como:
[tex]media=\frac{3+4+7+3+5+5+6+3+4}{9}[/tex]
Resolviendo:
media= 4,44
La media aritmética de las notas de Esteban si se cambia un 6 por un 7 es 4,44. Por lo que la media aritmética (promedio) cambia.
ModaPor otro lado, la moda de un conjunto de números es el número que aparece más a menudo dentro del grupo de datos.
En este caso, podes observar que la cantidad de veces que aparece cada número es:
3: 3 veces
4: 2 veces
5: 2 veces
6: 2 veces
Debido a que el 3 es el número con mayor cantidad de repeticiones, la nota que más se repite es 3.
Si de las notas de Esteban se cambia un 6 por un 7, se obtiene la serie de notas:
3, 4, 7, 3, 5, 5, 6, 3, 4
a cantidad de veces que aparece cada número es:
3: 3 veces
4: 2 veces
5: 2 veces
6: 1 vez
7: 1 vez
Debido a que el 3 es el número con mayor cantidad de repeticiones, la nota que más se repite es 3.
Entonces, podes observar que la moda es 3 y no varia si de las notas se cambia un 6 por un 7.
MedianaPor último, la mediana es valor que se encuentra en la mitad justa entre los valores máximo y mínimo de los datos con los que se está trabajando; es decir, que al ordenar los número de menor a mayor, éste se encuentra justamente en medio de los valores.
En este caso, ordenando de menor a mayor las notas de Esteban:
3,3,3,4,4,5,5,6,6
Se observa que el valor intermedio, es decir la mediana, de todas las notas de Esteban es 4.
Si de las notas de Esteban se cambia un 6 por un 7, se obtiene la serie de notas:
3, 4, 7, 3, 5, 5, 6, 3, 4
En este caso, ordenando de menor a mayor las notas de Esteban:
3,3,3,4,4,5,5,6,7
Se observa que el valor intermedio, es decir la mediana, de todas las notas de Esteban es 4. Por lo que la mediana no varia si de las notas se cambia un 6 por un 7.
En resumenEn resumen, la media aritmética es la única medida de tendencia central que cambia.

Savannah wants to leave a 15% tip. How much will lunch cost including the tax and the tip?
Answer:
$21.87
Step-by-step explanation:
Given that :
Cost of lunch = $18
Sales tax = 6.5%
Intended tip to leave = 15%
Cost of lunch including tip and tax =?
Sales tax = 0.065 * 18 = $1.17
Tip = 0.15 * $18 = $2.70
Cist of lunch including tip and tax :
($18 + $1.17 + $2.70)

Which graph represents the polynomial function h(x) = x3 + 2x2 – 11x – 12?
y
Answer:
I attached a pic of the answer. I just did the quiz. Hope this helps!!!
Step-by-step explanation:
The graph of the polynomial function h(x) = x³ + 2x² - 11x -12 has been shown.
Given that,
To determine the graph of the polynomial function h(x) = x³ + 2x² - 11x -12.
The graph is a demonstration of curves that gives the relationship between the x and y-axis.
Here,
The graph of the function h(x) = x³ + 2x² - 11x -12 can be drawn as the function is a polynomial of degree 3 so it will follow two ups and down,
So the graph can be drawn as shown in the image.
Thus, the graph of the polynomial function h(x) = x³ + 2x² - 11x -12 has been shown.

This if for my study guide and I'm so confused, can someone help me with this one?
Answer:
The form y=mx+b means slope m and y-intercept b; similarly, the form y=mx+a means slope m and y-intercept a.
The slope-intercept form of the equation of a line is a useful form for graphing as well as for understanding the relationship between x and y. In this lesson, learn how the slope-intercept form helps you understand the equation of a line.
The equation of a line can be written many different ways, and each of these ways is valid. The slope-intercept form of a line is a way of writing the equation of a line so that the slope of the line and the y-intercept are easily identifiable. The slope is the steepness of the line, and the y-intercept is the place the line crosses the y-axis.
A line is a relationship between two things - but not just any relationship. When you have a linear relationship, one that can be graphed as a line, there is one big condition:
No matter how much you have of a thing (often called x), if you add one more you always get a consistent amount more of the other thing (often called y).

Answer:
y= -2x + 80
Step-by-step explanation:
First, you need to find the slope, which can be done by subtracting the change in y over the change in x. The easiest points to pick are (30,20) and (40,0). Do 20-0 which is -20, then divide that by 40-30, and you get -2. Then to find the y intercept, pick a point (like 40,0). Then do 0 = -2(40) + b, and solving for b you get 80.
Ronald said that (8.0 × 107) + (6.2 × 103) = 14.2 x 1010. Amy added the numbers too and said the sum was 8.00062 × 107. Ronald then added the numbers a second time and came up with his original result. Whose solution is correct? Ronald is correct because 80,000,000 + 6,200 = 142,000,000,000.
Yes No B
Amy is correct because adding the decimals and then adding the exponents is not the correct procedure for adding numbers in scientific notation.
Yes No C
Amy is correct because 6.2 × 103 is a much smaller number than 8.0 × 107, so the sum of the two numbers cannot be as large as a decimal times 1010.
Yes No D
Ronald is correct because when you add the exponents in 107 and 103, you get 1010.

If ZMK APY, m M = 112 ° , m Y = 41 ° , m K = (13x 37) ° , and m A = (2y + 7) ° , find the values of x and y.
need a answer asap
Answer
13x-37=112
13x =149
X=11.4
2y+7=41
Y=24
The value of x and y respectively will be 13° and 17°.
Based on the equation that's given in the question, the value of x will be found thus:
13x - 37 = 112
Collect like terms
13x = 112 + 37
13x = 149
x = 149/13
x = 13
Also, note that 2y + 7 = 41, therefore, the value of y will be:
2y = 41 - 7
2y = 34
y = 34/2 = 17°
Therefore, the value of x and y respectively will be 13° and 17°.

since it goes by (x,y) label the given points
(6,7) and (10,10)
6 is your first x (x1)
7 is you first y (y1)
onto the next point...(10,10)
10 would be your second x (x2)
and your second y would also be 10 (y2)

Which of the following inequalities has a solution x≥−3
3(x−1)≤4x
x≥x+32
x6≤x2−1
x+4≥x3
Answer: A
Step-by-step explanation: 3(x-1) becomes 3x -3 ≤ 4x. Put all like variables on the same side, meaning you'll subtract 3x from both sides giving you -3 ≤ x. You can flip the equation around to make it look exactly like x ≥ -3
The inequality 3(x−1)≤4x is showing the solution x ≥−3. The correct option is A.
What is inequality?inequality is the relationship between two expressions that are not equal, employing a sign such as ≠ “not equal to,” > “greater than,” or < “less than.”.
The inequality 3(x-1) ≤ 4x will be solved as below:-
3(x-1) becomes 3x -3 ≤ 4x. Put all like variables on the same side, meaning you'll subtract 3x from both sides giving you -3 ≤ x. You can flip the equation around to make it look exactly like x ≥ -3. The complete solution is given below:-
3(x-1) ≤ 4x
3x - 3 ≤ 4x
-3 ≤ 4x - 3x
-3 ≤ x
x ≥ -3
Therefore, the inequality 3(x−1)≤4x is showing the solution x ≥−3. The correct option is A.
