English Translation

A school has a total of 475 students. We want to extract a sample of 80. Explain in detail how this sample is obtained by random sampling.

Solution

In random sampling, each member of the population has an equal chance of being surveyed or an equal chance of being a member of the sample.

For this Question, it will mean that each of the 475 students would have an equal chance of being part of the sample of 80 students. To use random sampling for this particular scenario, we would give all the students numbers from 1 to 475, we would then use a computer program to generate 80 random student numbers.

We could also put all the number in a bowl and randomly select 80 numbers from 475, that way, the sampling method would be as random as can be.

In Spanish/En español

En el muestreo aleatorio, cada miembro de la población tiene la misma probabilidad de ser encuestado o la misma probabilidad de ser miembro de la muestra.

Para esta pregunta, significará que cada uno de los 475 estudiantes tendría las mismas posibilidades de ser parte de la muestra de 80 estudiantes. Para usar el muestreo aleatorio para este escenario particular, le daríamos a todos los estudiantes números del 1 al 475, luego usaríamos un programa de computadora para generar 80 números de estudiantes al azar.

También podríamos poner todos los números en un tazón y seleccionar aleatoriamente 80 números de 475, de esa manera, el método de muestreo sería lo más aleatorio posible.

Hope this Helps!!!

x=3

step-by-step explanation:

this is really simple i saw that there was only one term (5x) and thought if that was 15 what would i have to multiply everything else to get it there? well if 5x became 15 then x would have to be 3 so plug the 3 in the x for the other equations and you get 15 for the other ones. so there you go. : )
