The burning times of scented candles, in minutes, are normally distributed with a mean of 249 and a standard deviation of 20. Fi
Marysya12 [62]

Answer:

The candle burns for 244 minutes.

Step-by-step explanation:

When the distribution is normal, we use the z-score formula.

In a set with mean \mu and standard deviation \sigma, the zscore of a measure X is given by:

Z = \frac{X - \mu}{\sigma}

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this question, we have that:

\mu = 249, \sigma = 20

Find the number of minutes a scented candle burns if it burns for a shorter time than 60% of all scented candles.

This is the 100-60 = 40th percentile, which is X when Z has a pvalue of 0.4. So X when Z = -0.253.

Z = \frac{X - \mu}{\sigma}

-0.253 = \frac{X - 249}{20}

X - 249 = -0.253*20

X = 244

The candle burns for 244 minutes.

1. Un representante de ventas debe visitar 6 ciudades durante un viaje. a) Si hay 10 ciudades en el área geográfica que va a vis
o-na [289]

Answer:

a) Hay 210 grupos diferentes de seis ciudades que el representante de ventas podrá seleccionar.

b) Hay 720 secuencias posibles existen para las seis ciudades designadas.

Step-by-step explanation:

a)  Se llama combinaciones de m elementos tomados de n en n a todas las agrupaciones posibles que pueden hacerse con los m elementos de forma que no entran todos los elementos , no importa el orden  y no se repiten los elementos. La combinación se calcula como:

C=\frac{m!}{n!*(m-n)!}

En este caso m corresponde a las 10 ciudades en el área geográfica que va a visitar, mientras que n corresponde a las 6 ciudades que debe visitar un representante de venta durante un viaje.

Entonces:

C=\frac{10!}{6!*(10-6)!}=\frac{10!}{6!*4!}

Considerando que el factorial ! indica que se deben multiplicar todos los números enteros y positivos que hay entre el número que aparece en la fórmula y el número 1, entonces la combinación dará como resultado:

C= 210

<u><em>Hay 210 grupos diferentes de seis ciudades que el representante de ventas podrá seleccionar.</em></u>

b) Se llama permutación de n elementos a cada una de las diferentes ordenaciones  que se pueden hacer con esos elementos.

Si se tiene un grupo de n objetos distintos, el número de maneras diferentes que podemos tomar un número r de objetos (r < n) del grupo, está dado por la fórmula de la permutación:

P=\frac{n!}{(n-r)!}

Si m=n para calcular el total de permutaciones se utiliza la fórmula:

P= n!

En este caso se utiliza esta última expresión, ya que se desea calcular las permutaciones de 6 ciudades en 6 posiciones:

P=6!

P=720

<u><em>Hay 720 secuencias posibles existen para las seis ciudades designadas.</em></u>

The radius of the semicircle in the following composite figure is 8.5 millimeters. What is the total area of the composite figur
nydimaria [60]

Answer:

13.35 millimeter. (About)

Step-by-step explanation:

To find the area or circumference of any circle, you need to use pi. So, if we are trying to fine the area of a <em>semicircle, </em>you use the the formula:

πr²/2

So, if the radius is 8.5,

8.5 · 3.14 = 26.69

Now we divide it by 2.

26.69 = 13.345

Since the question is asking to round to the hundredths, the answer will be 13.35 millimeters.

PtichkaEL [24]
Given that t<span>he area of the mojave desert is 25,000 square miles and a scale drawing of the mojave desert has an area of 10 square inches.

The scale of the map is given by

\sqrt{25,000} : \sqrt{10}  = \sqrt{2,500\times10} : \sqrt{10}  \\  \\ =50 \sqrt{10} : \sqrt{10} =50:1

Therefore, the scale of the drawing is 50 : 1.
