Answer:

Percent markup is 200%

Step-by-step explanation:

The cost of each stylus is

[tex]\frac{400}{200} = 2[/tex] dollars

The selling price of each stylus is $6

Percent markup  =

(Selling price - cost price)/cost price *100

[tex]\frac{6-2}{2} *100\\2*100\\200[/tex]%

Percent markup is 200%

Answer:

[tex]a_{n}[/tex] = [tex]a_{n-1}[/tex] × [tex]\frac{3}{4}[/tex]

Step-by-step explanation:

There is a common ratio r between consecutive terms

r = [tex]\frac{384}{512}[/tex] = [tex]\frac{288}{384}[/tex] = [tex]\frac{216}{288}[/tex] = [tex]\frac{3}{4}[/tex] , then recursive formula is

[tex]a_{n}[/tex] = [tex]a_{n-1}[/tex] × [tex]\frac{3}{4}[/tex] : a₁ = 512

Answer:

m = rise/run = 270/20.5 = 13.17

Step-by-step explanation:

Going from (9, 260) to (29.5, 530), we see that the horizontal change (in x) is 20.5 and the vertical change (in y) is 270.  Thus, the slope is

m = rise/run = 270/20.5 = 13.17

Answer:

Se puede resolver el sistema de ecuaciones por sustitución, igualación o determinante. La solución de este sistema es [tex](x,y) = \left(2,\frac{3}{5} \right)[/tex].

Step-by-step explanation:

Sea el sistema de ecuaciones que se describe abajo:

[tex]x+5\cdot y = 5[/tex] (1)

[tex]3\cdot x -5\cdot y = 3[/tex] (2)

Existen por lo menos tres métodos analíticos para la resolución de este sistema de ecuaciones:

(i) Sustitución

Despejamos [tex]x[/tex] en (1):

[tex]x = 5-5\cdot y[/tex]

Aplicamos la expresión resultante en (2):

[tex]3\cdot \left(5-5\cdot y\right)-5\cdot y = 3[/tex]

Luego, resolvemos la ecuación resultante:

[tex]15 - 15\cdot y -5\cdot y = 3[/tex]

[tex]-20\cdot y = -12[/tex]

[tex]y = \frac{3}{5}[/tex]

Luego, determinamos el valor de [tex]x[/tex]:

[tex]x = 2[/tex]

(ii) Igualación

Despejamos [tex]5\cdot y[/tex] en cada expresión:

[tex]5\cdot y = 5 - x[/tex] (3)

[tex]5\cdot y = 3\cdot x - 3[/tex] (4)

Ahora, igualamos (3) y (4) y simplificamos:

[tex]5-x = 3\cdot x -3[/tex]

[tex]4\cdot x = 8[/tex]

[tex]x = 2[/tex]

Finalmente, calculamos [tex]y[/tex] en (3):

[tex]y = 1 - \frac{x}{5}[/tex]

[tex]y = \frac{3}{5}[/tex]

(iii) Determinante

Aplicamos las siguientes fórmulas para determinar cada variable:

[tex]x = \frac{\left|\begin{array}{ccc}5&5\\3&-5\end{array}\right| }{\left|\begin{array}{ccc}1&5\\3&-5\end{array}\right|}[/tex]

[tex]x = \frac{-25-15}{-5-15}[/tex]

[tex]x = 2[/tex]

[tex]y = \frac{\left|\begin{array}{ccc}1&5\\3&3\end{array}\right| }{\left|\begin{array}{ccc}1&5\\3&-5\end{array}\right|}[/tex]

[tex]y = \frac{3-15}{-5-15}[/tex]

[tex]y = \frac{3}{5}[/tex]

Por ende, concluimos que la solución de este sistema es [tex](x,y) = \left(2,\frac{3}{5} \right)[/tex].

La solución de la ecuación x + 5y = 5 y 3x - 5y = 3 es (2, 0.6)

Ecuación

Una ecuación es una expresión utilizada para mostrar la relación entre dos o más números o variables.

Dadas las ecuaciones:

x + 5y = 5 (1)

Y:

3x-5y = 3 (2)

Resolviendo ambas ecuaciones 1 y 2 simultáneamente da:

x = 2, y = 0,6

La solución de la ecuación x + 5y = 5 y 3x - 5y = 3 es (2, 0.6)

Answer:

a. 1.52%

b. There is 95% probability that the true population percentage lies between 53.8$ and 56.62%

Step-by-step explanation:

The number of participants in the sample, n = 4,100

The percentage that watched the particular popular situation episode, p = 55.1%

a. The margin of error is given by the following formula;

[tex]Margin \ of \ Error = Z_{\alpha /2} \times \sqrt{\dfrac{p \times (1 - p)}{n} }[/tex]

Where;

Z = The z-score at 95% = 1.96

p = The proportion of the sample that responded positively = 55.1% = 0.551

n = 4,100

From the above data, we get;

[tex]Margin \ of \ Error = 1.96 \times \sqrt{\dfrac{0.551 \times (1 - 0.551)}{4,100} } \approx 0.0152252[/tex]

The margin of Error ≈ 1.52%

b. The confidence interval is give as follows;

[tex]p \pm Z_{\alpha /2} \times \sqrt{\dfrac{p \times (1 - p)}{n} }[/tex]

Therefore, we get the 95% confidence interval as follows'

55.1 - 1.52 ≤ μ ≤ 55.1 + 1.52

53.8%  ≤ μ ≤ 56.62%

The answer as formatted in an online source is presented as follows;

There is 95% probability that the true population percentage lies between 53.8$ and 56.62%.

Answer:

[tex]\sin{72^\circ}[/tex]

Step-by-step explanation:

In a right triangle, the two acute angles are complementary--they add up to 90 degrees.

Cosine is defined as the adjacent side divided by the hypotenuse.  In the attached picture,  [tex]\cos{18^\circ}=\frac{a}{h}[/tex].

The other acute angle is 90 - 18 = 72 degrees.  Looking at just that angle, side a is the opposite side.  So the ratio a/h is opposite over hypotenuse -- the sine ratio.

Therefor, [tex]\cos{18^\circ} = \sin{72^\circ}[/tex]

Answer: 80

Step-by-step explanation:

As  45 %  of a number is  36 ,

45 % × Number = 36

or  45 /100 × Number = 36

45 /100 × 100 /45 × Number =36 × 100 /45

Number = 4 × 100 / 5

Number=80
