Answer:
El orden de menor a mayor es:
1, 1, 1, 1, 1, 1, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 4, 4, 4, 4
La mediana es 3.
Step-by-step explanation:
En la ciudad se hizo la relación de hoteles según la lista de estrellas, la cual se ordena de menor a mayor. Entonces, el orden determinado es:
1, 1, 1, 1, 1, 1, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 4, 4, 4, 4
La mediana de un conjunto de números es el número medio en el conjunto, una vez que los números han sido ordenados de menor al mayor, o, si hay un número par de datos, la mediana es el promedio de los dos números medios.
En este caso el conjunto posee 38 datos. Cuando el número de observaciones es par es posible calcular la mediana como:
[tex]Mediana=\frac{n+1}{2}[/tex] donde n es la cantidad de observaciones.
Entonces:
[tex]Mediana=\frac{38+1}{2}[/tex]
Mediana= 19.5
Esto indica que el valor de la mediana se encuentra en la observación cuya posición esta entre la 19 y la 20. Entonces el valor de la mediana será una media de los valores que están en la posición 19y 20. Estos números son 3 y 3. La media entre estos dos números es:
[tex]\frac{3+3}{2} =3[/tex]
La mediana es 3.
Pregunta completa:
Los hoteles están clasificados por estrellas de 1 a 5 de acuerdo con la ubicación, atención servicios y lujos que proporcione al turista. En una ciudad se hizo la relación de hoteles según la siguiente lista de estrellas: 3, 3, 4, 3, 4, 3, 1, 3, 4, 3, 3, 3, 2, 1, 3, 3, 3, 2, 3, 2, 2, 3, 3, 3, 2, 2, 2, 2, 2, 3, 2, 1, 1, 1, 2, 2, 4, 1.
Ordena el conjunto de estrellas y encuentra la
mediana (Yo).
Responder:
3
Explicación paso a paso:
Dados los datos:
3, 3, 4, 3, 4, 3, 1, 3, 4, 3, 3, 3, 2, 1, 3, 3, 3, 2, 3, 2, 2, 3, 3, 3, 2, 2, 2, 2, 2, 3, 2, 1, 1, 1, 2, 2, 4, 1.
Datos reorganizados:
1, 1, 1, 1, 1, 1, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 4, 4, 4, 4
Mediana: 0.5 (n + 1) th término
Mediana = 0.5 (38 + 1) th término
Mediana = 0,5 (39) término
Mediana = 19,5 a término
(Término 19.5 + Término 20) = (3 +3) / 2 = 3
La mediana = 3
can you show a video or a pic of the answer 3.4 mi/h = ft/sec
Answer:
4.99 ft/sec
Step-by-step explanation:
1 mile = 5280 feet
3.4 miles = 17952 feet or (3.4 x 5280= 17952)
1 hour = 3600 seconds (60 minutes per hour x 60 seconds per minute)
17952 feet / 3600 seconds = 4.99 feet per second

Please find the value of this one expression
Answer:
Solving the expression [tex]\frac{2}{\sqrt[6]{8} }.\sqrt{2}-(-\frac{18}{\sqrt{81} } -2)[/tex] we get 6
The answer is 6.
Step-by-step explanation:
We need to find value of expression: [tex]\frac{2}{\sqrt[6]{8} }.\sqrt{2}-(-\frac{18}{\sqrt{81} } -2)[/tex]
We know that [tex]\sqrt{81}=9[/tex]
Our expression will become
[tex]\frac{2}{\sqrt[6]{8} }.\sqrt{2}-(-\frac{18}{\sqrt{81} } -2)\\=\frac{2}{\sqrt[6]{8} }.\sqrt{2}-(-\frac{18}{9 } -2)\\=\frac{2}{\sqrt[6]{8} }.\sqrt{2}-(-2 -2)\\=\frac{2}{\sqrt[6]{8} }.\sqrt{2}-(-4)\\=\frac{2}{\sqrt[6]{8} }.\sqrt{2}+4[/tex]
We can write [tex]\sqrt[6]{8}=(2^3)^{\frac{1}{6}}=(2)^{\frac{3}{6}}=2^\frac{1}{2}=\sqrt{2} \\[/tex]
Now, replacing [tex]\sqrt[6]{8}=\sqrt{2}[/tex]
[tex]=\frac{2}{\sqrt[6]{8} }.\sqrt{2}+4\\=\frac{2}{\sqrt{2} }.\sqrt{2}+4\\=2+4\\=6[/tex]
So, solving the expression [tex]\frac{2}{\sqrt[6]{8} }.\sqrt{2}-(-\frac{18}{\sqrt{81} } -2)[/tex] we get 6
a. y = 3/4x - 5 I'm confused on how I'm suppose to find the slope and y-intercept.
Answer:
The slope is 3/4 and the y-intercept is -5.
Step-by-step explanation:
Your equation is already in slope-intercept form, so all you have to do is look at it. Slope-intercept form looks like y = mx + b, where m is the slope and b is the y-intercept. Hope that helps!
Lines AB and MN intersect at P.

(3x + 24)
(9x - 54)
P
B
M
What is the value of x?
Answer:
x = 13
Step-by-step explanation:
To solve for x, we set equations (9x - 54) and (3x + 24) equal to each other because the angles are equal
(9x - 54) = (3x + 24); add 54 to both sides
9x = 3x + 78; subtract 3x from both sides
6x = 78; now divide by 6
x = 13

-5w = -80. solve for w.
Answer:
w=16
Step-by-step explanation:
-5w = - 80 Divide both sides of the equation by- 5 -5w ÷(-5)= - 80 ÷ ( - 5 ) any expression divided by itself equals 1 w = - 80 ÷ ( - 5 ) = w = 16 also you should use photomath that's what I use
Answer:
w=16
Step-by-step explanation: -80/-5=16
Write the equation of the line y=(5)/(6)x+(7)/(6) perpendicular to
that passes through the point (-8,7)
Answer:
6x + 5y + 13 = 0.
Step-by-step explanation:
y = 5/6x + 7/6
Gradient = 5/6
Since the line is perpendicular to y = 5/6x + 7/6
then its gradient is -6/5.
Hence its equation is: point (-8,7).
y - 7 = -6/5(x -(-8))
multiplying through by 5 we get;
5y - 35 = -6(x + 8)
5y - 35 = -6x - 48
6x + 5y + 13 = 0

Tiara earns $33 washing 3 cars. At this rate, how much does Tiara earn washing 9 cars?
Answer:
$99
Step-by-step explanation:
Answer:
$99 (Verified Answer) ✅Step-by-step explanation:
The best way to solve this is to use a proportion. However, since this is a rate, we could also find the unit rate and multiply it by the number of cars Tiara is washing.
Method 1: Proportion[tex]\frac{33}{3} = \frac{x}{9}[/tex]
3x = 33 x 9
3x = 297
Now, we simply divide by 3 to get $99.
We can check this by substituting the value of x in the original proportion.
3(99) = 33 x 9
297 = 297 ✅
Method 2: Unit RateThe other way to solve this is to divide the whole expression by the number of cars to find the unit rate. In other words, how much money does she get for washing 1 car. We can then multiply this by the number of cars to get the answer.
$33/3 for 3/3 cars
$11 for 1 car
Now, we will multiply by the number of cars she washes in this question, which is 9
$11 x 9 = 99 for 1 x 9 cars
$99 for 9 cars
Again, we have the correct answer, which we have already verified by the process above. As you can see, both methods work. However, the top method is easier and since it uses algebra, is almost foolproof, so long as the algebraic processess are followed.

Find the equation that shows the relationship between the number of pens, p, and the
total cost, c.
5

20
Number of Pens (p)
$3.95
$7.90
$11.85
$15.80
Cost (c)
Answer: c= 0.79p
Step-by-step explanation:
Divide each cost by the number of pens it have to find the constant change value.
3.95/5 = 0.79
7.90/10= 0 .79
11.85/15 = 0.79
15.80 / 20 = 0.79
Since the constant change is 0.79 which means that for each pen it will cost you $0.79, then the equation will be c= $0.79p where c is the cost and p is the number of pens.
it takes 3 tractors 2 hours to plow a square field whose side is 600 meters. find the number of hours it would take 5 tractors to plow a square field whose side is 1000 meters.
PLEASE ANSWER FAST. 200 POINTS
Answer:
5 tractors can plow a square field of side length 1,000 meters in 3.33 hours (3 hours 20 minutes)
Step-by-step explanation:
Let's find out how much each tractor can plow each hour.
[tex]\frac{600^{2} }{3*2}=60,000m^{2}[/tex] per tractor per hour
[tex]1,000^{2}=1,000,000m^{2}[/tex] is the area of the field of side length 1,000 meters
5 tractors can plow [tex]300,000m^{2}[/tex] per hour.
[tex]\frac{1,000,000}{300,000}=3.33[/tex] hours
