1 times something is the same number

so

\frac{6}{ \frac{3}{4} }


make bottom 1
3/4 times 4/3=12/12=1 so

times wole thing by
\frac{\frac{4}{3}}{ \frac{4}{3} }

result
\frac{(6)(\frac{4}{3})}{(\frac{3}{4})(\frac{4}{3}) }=
\frac{\frac{24}{3}}{\frac{12}{12} }=
\frac{8}{1 }=8

basically
a/b divided by c/d=a/b times d/c, invert and multiply

Una empresa fabrica dos modelos de DVD: el modelo A y el modelo B. Se dispone de 50 kilogramos de caucho y de 80 horas de mano d
alexandr1967 [171]

Answer:

¿Cuántos DVD de cada tipo debe fabricar y vender para que la utilidad sea máxima?

Se debe fabricar y vender 20 DVD del modelo A y 30 DVD del modelo B. La utilidad máxima es de de S/. 1 800

Step-by-step explanation:

x : Número de DVD del modelo A

y : Número de DVD del modelo B.

                               MODELO A MODELO B TOTAL

Cantidad de caucho                  1x 1x                 50 kg.

Horas de mano de obra           1x 2x                 80 horas

U : Utilidad mensual.

La función objetivo, que se debe maximizar, es:

U=30   + 40y

x+ y \leq 50\\  

x + 2y \leq 80

x\geq 0

y\geq 0

Las coordenadas de los vértices de la región factibles son:

A (0, 0) B (50, 0) C (20, 30) D(0, 40)

Entonces, se evalúa la función objetivo en cada punto:

U (0, 0) = 30 (0) + 40 (0) = 0

U (50, 0) = 30 (50) + 40(0) = 1500

U (90, 0) = 30 (20) + 40 (30) = 1800

U (0, 40) = 30 (0) + 40 (40) =1600

Por consiguiente U tiene un valor máximo en C , en donde: x =20 ,  y = 30 .

Se debe fabricar y vender 20 DVD del modelo A y 30 DVD del modelo B. La utilidad máxima es de de S/. 1 800.

 

 30 x  40 y

 

s.a.

What is the answer to -50+15+-50?
Yakvenalex [24]

Answer:

-85

Step-by-step explanation:

Note that -50 + 15 = -35.

Next, we want to do -35 + -50. This means we next work out -35 - 50 (as plussing a negative number is equivalent to minusing).

So we get -35 - 50 = -85.

A sample of 64 was taken from a population, with the mean of the sample being 119 and the standard deviation of the sample being
Fofino [41]
We have the sample size, sample mean and the sample standard deviation. Since the population standard deviation is not know, we will use t-distribution to find the confidence interval.

The critical t value for 95% confidence interval and 63 degrees of freedom is 1.998.

The 95% confidence for the population mean will be:

(119-1.998 *\frac{16}{ \sqrt{64} } ,119+1.998 *\frac{16}{ \sqrt{64} }) \\  \\ 
=(115.004, 122.996) \\ \\=(115,123)

Thus, the 95% confidence interval for the population mean will be (115,123)

So, option A is the correct answer
