An electronics store buys 200 stylus at a cost of $400 and sells them for $6 each. Find the percent markup rounded to the nearest percent?
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%
X+5y=5 3x-5y=3 Necesito ayuda, procedimiento para resolverlos y maneras distintas de resolverlos. Denuncio a quien venga por los puntos.
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:
[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
if the two points are (9, 260) and (29.5, 530), calculate the slope of the line that runs through them.
A. 13.17
B. 12.25
C. 11.32
D. 10.42
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

Using a random sample of 4100 households, a media research company finds that 55.1% watched a particular episode of a popular situation comedy. a. Find the margin of error in this percent. b. Write a statement about the percentage of TV households in the population who watched the episode of the situation comedy.
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%.

length=2
width=2
height=3
Answer:
12
Step-by-step explanation:
The computation of the volume of the rectangular prism is shown below:
As we know that
The volume of the rectangular prism is
= length × width × height
where
Length is 2
width be 2
And, the height be 3
So, the volume of the rectangular prism is
= 2 × 2 × 3
= 12
