Pren recorded this data set, which contains an outlier. 204, 216, 111, 224, 230, 211, 210, 198, 200, 218 What numbers represent

melamori03 [73]

Answer:

The correct option is D.

Step-by-step explanation:

The given data is

204, 216, 111, 224, 230, 211, 210, 198, 200, 218

Arrange the data in ascending order,

111, 198, 200, 204, 210, 211, 216, 218, 224, 230

The range is the difference between maximum value and minimum value.

$Range=\text{upper limit}-\text{lower limit}$

$Range=230-111=119$

Divide the data it two equal parts.

(111, 198, 200, 204, 210), (211, 216, 218, 224, 230)

Now divide the each in two equal parts.

(111, 198), 200, (204, 210), (211, 216), 218, (224, 230)

The mid value of first part is 200 and the mid value of second part is 218.

$\text{lower quartile}=Q_1=200$

$\text{Upper quartile}=Q_3=218$

Therefore option D is correct.

4. Elena va a una fiesta pero no sabe que ponerse, así que lanza un moneda y un dado al

taurus [48]

Answer:

<u>1/4</u>

Explanation:

Hola. Puesto que tu pregunta está en español, te responderé en el mismo lenguage.

Estas son las posibilidades dadas por la combinación moneda/dado

Número de combinaciones

Moneda: prenda

Cara: vestido 1 de 2: 1/2

Sello: falda 1 de 2: 1/2

Dado: color

Par: negro 3 de 6: 3/6

Impar: café 3 de 6: 3/6

En total son 2 × 6 resultados: 12 (incluye resultados repetidos, no son todos diferentes entre sí)

¿Cuántas combinaciones tienen vestido y color negro?

P(Vestido∩negro) = ?

Es decir: moneda = cara y dado = par

Son 1 × 3 = 3.

Por tanto, la probabilidad de vestido negro es:

3 de 12 = 3/12 = 1/4 ← respuesta

Hay otras formas de resolverlo. Por ejemplo;

Como los resultados de lanzar la moneda y el dado son independientes:

P(Vestido∩negro) = P(Vestido) × P(Negro)
P(Vestido) = 1/2
P(Negro) = 3/6 = 1/2

P(Vestido) × P(Negro) = 1/2 × 1/2 = 1/4 ← mismo resultado

Plzz HELP FOR POINTS AND BRAINLIST ANSWER

A)Plugging in our initial statement values of y = 16 when x = 10, we get:

16 = 10k

Divide each side by 10 to solve for k:

16/10=

k = 1.6

Solve the second part of the variation equation:

Because we have found our relationship constant k = 1.6, we form our new variation equation:

y = 1.6x

Since we were given that x, we have

y = 1.6()

y = 0

B)Plugging in our initial statement values of y = 1 when x = 15, we get:

1 = 15k

Divide each side by 15 to solve for k:

1/15

=15k

k = 0.066666666666667

Sara is building a triangular pen for her pet rabbit. If two of the sides measure 8 feet and 15 feet, the length of the third si

Nesterboy [21]

Answer:

1) 13 ft

Step-by-step explanation:

1) 13+8=21 which is greater than 15. Would be a triangle.

2) 7+8=15 This would be a single line, not a triangle.

3) 3+8<15 This would be a single line, not a triangle.

2) 15+8=23 This would be a single line, not a triangle.
