Ejercicio. Supongamos que el total de estudiantes en tu escuela es 256. Se te ha pedido elegir

al azar una muestra de 15 estudiantes a los cuales se les aplicará un examen para evaluar las

condiciones físicas en las que se encuentran. Describe en tu libreta al menos dos maneras

diferentes de como podrías realizar la selección de manera que los 15 estudiantes representen

una buena muestra del total de estudiantes

Responder:

Por favor, consulte la explicación

Explicación paso a paso:

Para garantizar que la selección realizada sea representativa, la selección debe ser aleatoria.

1.) Se puede elegir una muestra totalmente aleatorizada de 15 integrantes de niños y niñas en igual proporción. Es decir, si toda la población tiene un 60% de niñas y un 40% de niños, entonces una muestra puede incluir;

0.4 * 15 = 6 niños

0,6 * 15 = 9 niñas

Además, la muestra se puede seleccionar asignando al azar 15 números a un trozo de papel enrollado donde se les puede pedir a todos los estudiantes que elijan. los estudiantes que eligen los trabajos numerados se utilizan como muestra.

for all positive angles less than 360°, if csc csc (2x+30°)=cos cos (3y-15°), the sum of x and y is?​

Answers

Answer:

35 degrees

Step-by-step explanation:

for all positive angles less than 360°, if csc (2x+30°)= cos (3y-15°), the sum of x and y is?​

Let the given expression be equal to 1, hence;

csc (2x+30°)= cos (3y-15°) = 1

csc (2x+30°) = 1

1/sin(2x+30) = 1

1 = sin(2x+30)

sin(2x+30) = 1

2x+30 = arcsin(1)

2x+30 = 90

2x = 90-30

2x = 60

x = 60/2

x = 30 degrees

Get the value of y;

cos (3y-15°) = 1

3y - 15 = arccos (1)

3y - 15= 0

3y = 0+15

3y = 15

y = 15/3

y = 5

Sum of x and y;

x+y = 30 + 5

x+y = 35degrees

Hence the sum of x and y is 35 degrees

Bailey is twice as old as Cala. Antoine is 9 years older than Cala and ​3 years older than Bailey. How old is Antoine?

Answers

Answer:

15 years old

Step-by-step explanation:

bailey is 12, and cala is 6

6 + 9 = 15

12+ 3 = 15

The age of antoine should be considered as the 15 years old when balley is twice to cala. And, to understand the calculations check below.

Calculation of the age;

Since

Bailey is twice as old as Cala. Antoine is 9 years older than Cala and ​3 years older than Bailey.

So based on this, we can say that

Here we assume Cala age be x

So, Bailey age be 2x

Now Antoine age be 9 + x

And, 3 + 2x

So,

9 - x = 3 - 2x

9 - 3 = x

x = 6

So here Cala age be 6

Bailey age be 12

So ,here the Antoine age be

= 9 + 6

= 15

The simplification of the given algebraic expression is 20x + 8y. The correct option is (C).

What is an Algebraic expression?

An algebraic expression can be obtained by doing mathematical operations on the variable and constant terms.

The variable part of an algebraic expression can never be added or subtracted from the constant part.

The given algebraic expression is 4(5x + 2y).

It can be simplified as follows,

4(5x + 2y)

= 4 × 5x + 4 × 2y

= 20x + 8y

Hence, the expression that is equivalent to 4(5x + 2y) is 20x + 8y.

Answers

Answer:

8138.88 cubic unit.

Step-by-step explanation:

Given that,

Radius, r = 12

Height, h = 18

We need to find the volume of the prop. The volume of a cylinder is given by the formula as follows :

[tex]V=\pi r^2 h\\\\V=3.14\times 12^2 \times 18\\\\V=8138.88\[/tex]

So, the volume of the cylinder is 8138.88 cubic unit.
