Determine the mode(s) of the data 2, 2, 2,3,5,5, 6, 7, 8, 8, 8, 9, 10.
Genrish500 [490]

To find the mode, put all the numbers in order from least to greatest, then count how many times you see a number. The number you see the most is the mode. In this problem, we have more than one mode, we have two. The number two appears three times and so does number eight. Having two modes is called bimodal, and having more than two modes is called multimodal. So we have a bimodal of two and eight from this data.

100 stickers are evenly divided between 16 children how many stickers will be left over at the end
puteri [66]

Answer:

4

Step-by-step explanation:

First, we can know our multiplication charts and know that 16 x 6 = 96

96 is the closest we can get to 100 while still having a remainder, which is 4

4 is the remainder, and is the amount left over.

La cantidad requerida de un producto es de 100 unidades, cuando el precio es de $58 por unidad, y de 200 unidades, cuando el pre
Jobisdone [24]

Answer:

La expresión lineal es; 7y = 6500 - 100x

Step-by-step explanation:

Necesitamos entender que todos los modelos lineales siguen u obedecen la ecuación de una línea recta.

Matemáticamente, la ecuación de una línea recta se puede representar como;

y = mx + c

donde m representa la pendiente de la línea yc representa la intersección en y de la línea.

Para responder adecuadamente a esta pregunta, podemos ver que tenemos dos puntos de trama diferentes. Podemos visualizar nuestro modelo como una gráfica lineal del número de unidades contra el precio. Donde el número de unidades está en el eje y, y el precio está en el eje x.

Verifique el archivo adjunto para ver un diagrama de cómo debe verse la trama.

Ahora, calculemos la pendiente de nuestra línea que tiene 2 puntos en la línea;

(58,100) y (51,200)

Para calcular la pendiente m, podemos usar la relación matemática de la siguiente manera;

m = (y2-y1) / (x2-x1) = (200-100) / (51-58) = -100/7

Ahora tenemos la pendiente pero no tenemos la intersección en y.

Para obtener la intersección con el eje y, utilizamos cualquiera de los dos puntos de datos.

Usaré el segundo;

La ecuación de la línea en ese punto será;

200 = -100 / 7 (51) + c

 Tenemos;

7c = 1400 + 5100

7c = 6500

c = 6500/7

Ahora completemos nuestro modelo lineal ya que ahora tenemos la pendiente y la intersección en y

y = - (100/7) x + 6500/7

7 años = -100x + 6500

o simplemente 7y = 6500-100x

Find the product. (x-3)^2
r-ruslan [8.4K]
Greetings and Happy Holidays!

Find the Product:
(x-3)^2

Expand:

=(x-3)(x-3)

Use FOIL or other techniques to solve binomial multiplication:
=x(x-3)-3(x-3)

=x^2-3x-3(x-3)

=x^2-3x-3x+9

Combine like terms:
=x^2-6x+9

The Answer Is:
\boxed{=x^2-6x+9}

I hope this helped!
