The unit rate would be $0. 99 or 99cents per pound of candy. The equation dissected is, candy = $0.99 • lbs (pounds), and for each pound of candy bought you have to pay 99 cents.

Hope this helped!

AnnZ [28]

Answer:

Kindly check explanation

Step-by-step explanation:

Given the data:

Sales(y) __Radio (x1) __ Newspaper (x2)

973 0 40

1119 0 40

875 25 25

625 25 25

910 30 30

971 30 30

931 35 35

1177 35 35

882 40 25

982 40 25

1628 45 45

1577 45 45

1044 50 0

914 50 0

1329 55 25

1330 55 25

1405 60 30

1436 60 30

1521 65 35

1741 65 35

1866 70 40

1717 70 40

The multiple regression equation obtained for the data:

With sales, y = predicted variable

Radio, x1 = predictor variable 1

Newspaper, x2 = predictor variable 2

ŷ = 13.10812X1 + 17.07885X2 + 149.19284

Slope b1, = for every unit change in Number of radio advert, there is a 13.10812 change in sales

Slope B2, = for every unit change in Number of newspaper advert, there is a 17.07885 change in sales

b0 = intercept = 149.19284, represents the estimated amount of sales if there was no sales reported from both radio and newspaper advert.

Sales where, X1 = $20,000; X2 = $20,000

ŷ = 13.10812(20000) + 17.07885(20000) + 149.19284

y = 603888.59284

Sales (y) = $603889

Resolver el siguiente sistema de ecuación:
snow_tiger [21]

Answer:

x=-1\\y=4

Step-by-step explanation:

\frac{5x+2y}{3}=1

\frac{2x+y}{2}=1

Vamos a utilizar el método de sustitución. Vamos a despejar la segunda ecuación por alguna de las variables. Elegiré la y porque esta sola.

\frac{2x+y}{2}=1

Vamos a empezar por eliminar ese 2 del denominador. Para hacer esto, multiplicamos por 2 ambos lados de la ecuación.

2x+y=1*2

2x+y=2

Como vamos a despejar la y, restamos 2x en ambos lados.

y=2-2x

Listo.

------------------------------------------------------------------------

Procedemos a reemplazar el valor de y en la primera ecuación.

\frac{5x+2y}{3}=1

\frac{5x+2(2-2x)}{3}=1

\frac{5x+4-4x}{3} =1

Procedemos a operar términos semejantes.

\frac{x+4}{3} =1

Nos deshacemos del 3 multiplicando.

x+4=1*3\\x+4=3

Restamos 4

x=3-4\\x=-1

-----------------------------------------------------------------------------

Una vez encontrado el valor de x, procedemos a reemplazar en cualquier ecuación para encontrar el valor de y. Usaré la segunda ecuación.

\frac{2x+y}{2}=1

\frac{2(-1)+y}{2}=1

Procedemos a resolver;

\frac{-2+y}{2} =1

Multiplicamos por 2.

-2+y=1*2

-2+y=2

Sumamos 2

y=2+2\\y=4

-------------------------------------------------------------------------------

Para comprobar que los valores son correctos, reemplazamos ambos valores en cualquier ecuación y el resultado debe ser igual.

Usaré la primera.

\frac{5x+2y}{3} =1

\frac{5(-1)+2(4)}{3} =1

Resolvemos;

\frac{-5+8}{3} =1

\frac{3}{3}=1

1=1
