A certain city divides naturally into ten district neighborhoods. How might a real estate appraiser select a sample of single-fa

mily homes that could be used as a basis for developing an equation to predict appraised value from characteristics such as age, size, number of bathrooms, distance to the nearest school, and so on?
An appropriate method is to sample the most expensive homes in a randomly selected district. An appropriate method is to generate a simple random sample of all single-family homes in the city or a stratified random sample by taking a simple random sample from each of the ten district neighborhoods. An appropriate method is to randomly select which district to survey, and record data for each home in that district. An appropriate method is to sample the newest homes in all ten districts.

Answer:

An appropriate method is to generate a simple random sample of all single-family homes in the city or a stratified random sample by taking a simple random sample from each of the ten district neighborhoods.

Step-by-step explanation:

Since, the city is very large and it is divided into ten districts. So, collecting sample from one district or any particular are did not give the correct estimate of whole city. So, the appropriate method to collect sample is taking the sample randomly from each district and this type of sampling method is called Stratified Sampling.

Problem 2. Smasher Van bound for Koronadal City leaves Polomolok every 15 minutes
astraxan [27]

Answer:

5. c. Every 1 hour

6. c. 4 times

7. b. 3 times

Step-by-step explanation:

The given parameters of the rate of departure of the two vans are;

The rate of departure of Smasher Van bound for Koronadal City = Every 15 minutes

The rate of departure of Nustafa Van= Every 20 minutes

5. The time, 'x', when the two vans leave at the same time is given by the Lowest Common Multiple (LCM) of 15 and 20 as follows;

Multiples of 15 = 15, 30, 45, 60

Multiples of 20 = 20, 40, 60

Therefore, the LCM of 15 and 20 = 60

The time, when the two vans leave at the same time = Every 60 minutes = Every 1 hour

The time, when the two vans leave at the same time = Every 1 hour

6. The number of times the Smasher Van leaves Polomolok so that the two vans leave together is given by the number of multiples 15 minutes in 60 minutes = 60 minutes/(15 minutes) = 4 times

7. The number of times the Nustafa Van leaves Polomolok so that the two vans leave together is given by the number of multiples 20 minutes in 60 minutes = 60 minutes/(20 minutes) = 3 times.

Un medico receta a un paciente tomar una pastilla cada 6 horas y un jarabe cada 8 horas. Si
Xelga [282]

Queremos ver cuando será la proxima vez que una persona <u>tome dos medicamentos al mismo tiempo</u> dado que los toma en intervalos regulares.

Veremos que luego de 24 horas el paciente volvera a tomar ambos medicamentos juntos.

Sabemos que el paciente toma una pastilla cada 6 horas y un jarabe cada 8 horas.

El paciente volvera a tomar ambos medicamentos juntos en el primer multiplo comun de 6 y 8.

Para encontrarlo podemos simplemente escribir los multiplos de cada uno y ver cual es el primero que aparece para ambos números:

6*1 = 6

6*2 = 12

6*3 = 18

6*4 = 24

y

8*1 = 8

8*2 = 16

8*3 = 24

Podemos ver que 24 es un multiplo comun (el primero) de 6 y 8.

Esto significa que luego de 24 horas el paciente volvera a tomar ambos medicamentos juntos.
