Answer: The angles inside a triangle are called interior angles. ... The three interior angles in a triangle will always add up to 180°. At each corner the exterior and interior angles are on a straight line, so at each corner these two angles add up to 180°.

Step-by-step explanation:

Sal proves that the angles of an equilateral triangle are all congruent (and therefore they all measure 60°), and conversely, that triangles with all congruent angles are equilateral.

Answer:

y = -x + 9.5

this is the answer to the line parallel to y=-x that passes through (7, 2.5)

Answer:

The method of solving "by substitution" works by solving one of the equations (you choose which one) for one of the variables (you choose which one), and then plugging this back into the other equation, "substituting" for the chosen variable and solving for the other. Then you back-solve for the first variable.

Step-by-step explanation:

Solve the following system by substitution.

2x – 3y = –2

4x +   y = 24

The idea here is to solve one of the equations for one of the variables, and plug this into the other equation. It does not matter which equation or which variable you pick. There is no right or wrong choice; the answer will be the same, regardless. But — some choices may be better than others.

For instance, in this case, can you see that it would probably be simplest to solve the second equation for "y =", since there is already a y floating around loose in the middle there? I could solve the first equation for either variable, but I'd get fractions, and solving the second equation for x would also give me fractions. It wouldn't be "wrong" to make a different choice, but it would probably be more difficult. Being lazy, I'll solve the second equation for y:

4x + y = 24

y = –4x + 24

Now I'll plug this in ("substitute it") for "y" in the first equation, and solve for x:

2x – 3(–4x + 24) = –2

2x + 12x – 72 = –2

14x = 70

x = 5

Answer:

x = -1/2

Step-by-step explanation:

-2(8x - 1) = 4(3x + 4)

Simplify

-16x + 2 = 12x + 16

Subtract 12x from both sides

-28x + 2 = 16

subtract 2 from both sides

-28x = 14

divide both sides with -28

x = -14/28

simplify

x = -1/2

Answer:

x = -1/2

Step-by-step explanation:

-2(8x - 1) = 4(3x + 4)

-16x + 2 = 4(3x + 4)

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.

La 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.

Por 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.

Por 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 resumen, la media aritmética es la única medida de tendencia central que cambia.

9514 1404 393

Answer:

Step-by-step explanation:

Apparently, you are supposed to assume that ...

  y = g(x)

  y = 4 - x

For the one given value of x, the corresponding y value is ...

  y = 4 - 3 = 1

So, for that x-value, the table entry is (x, y) = (3, 1).

__

To find the missing x-values, you can solve the equation for x.

  y = 4 - x

  x + y = 4 . . . . add x

  x = 4 - y . . . .  subtract y

Now, for the given y-values, we can find the corresponding x:

  x = 4 -(-1) = 5   ⇒   (x, y) = (5, -1)

  x = 4 -(4) = 0   ⇒   (x, y) = (0, 4)

So, your table will be ...

Answer:

P(x)=2x-60

Step-by-step explanation:

From the information provided, the function P(x) would indicate that the total profit you earned from selling x cups of lemonade is equal to the result of multiplying the price per cup for the number of cups minus the total cost. This cost is the result of adding up the cost of buying wood plus the cost per cup for the number of cups:

P(x)=5x-(60+3x)

P(x)=5x-60-3x

P(x)=2x-60

According to this, the function is: P(x)=2x-60.
