Critérios de divisibilidade dos números 2,3,4,5,6,8 e 10

Mathematics

3 0

Step-by-step explanation:

Los criterios de divisibilidad nos ayudan a saber de antemano cuándo un número natural es divisible por otro.

Ser divisible significa que cuando dividimos estos números, el resultado será un número natural y el resto será igual a cero.

Presentaremos los criterios de divisibilidad por 2, 3, 4, 5, 6, 7, 8, 9 y 10.

Divisibilidad por 2

Cada número cuyo dígito unitario sea par será divisible por 2, es decir, los números que terminan en 0, 2, 4, 6 y 8.

Ejemplo

El número 438 es divisible por 2 ya que termina en 8, que es un número par.

Divisibilidad por 3

Un número es divisible por 3 cuando la suma de sus dígitos es un número divisible por 3.

Ejemplo

Verifica que los números 65283 y 91277 sean divisibles por 3.

Solución

Sumando los dígitos de los números indicados, tenemos:

6 + 5 + 2 + 8 + 3 = 24

9 + 1 + 2 + 7 + 7 = 26

Dado que 24 es un número divisible por 3 (8. 3 = 24), entonces 65283 es divisible por 3. El número 26 no es divisible por 3, por lo que 91277 tampoco es divisible por 3.

Divisibilidad por 4

Para que un número sea divisible entre 4, sus dos últimos dígitos deben ser 00 o divisibles entre 4.

Ejemplo

¿Cuál de las siguientes opciones tiene un número que no es divisible por 4?

a) 35748

b) 20500

c

) 97235 d) 70832

Solución

Para responder a la pregunta, verifiquemos los dos últimos dígitos de cada opción:

a) 48 es divisible por 4 (12. 4 = 48).

b) 00 es divisible por 4.

c) 35 no es divisible por 4, ya que no hay un número natural que multiplicado por 4 sea igual a 35.

d) 32 es divisible por 4 (8.4 = 32)

Entonces la respuesta es la letra c. El número 97235 no es divisible por 4. S

Let ask be the number of points that you can be scored on one question of a statistics exam below is the probability distributio
Molodets [167]

The probability that x will be at most 2 will be 0.89.

<h3>What is probability?</h3>

It should be noted that probability simply means the likelihood of the occurence of an event that's given.

Based on the information, let the number of points that can be scored on the statistics examination be depicted by x.

Therefore, the probability that x will be at most 2 will be:

= P(x = 0) + P(x = 1) + P(x = 2)

= 0.13 + 0.21 + 0.55

= 0.89

Therefore, the probability that x will be at most 2 will be 0.89.

Complete question:

Let x be the number of points that can be scored on 1 question of a statistics exam. Below is the probability distribution of how students did. x 0 1 2 3 P(x ) 0.13 0.21 0.55 0.11 Find the probability that x is at most 2.

1)The square shown has a perimeter of 32 units. The square is rotated about line k. 
natali 33 [55]
1. The perimeter of the square is 32 units, means each side is 32/4=8 units.

rotating the square about line k forms a cylinder with base radius equal to 8 units, and height equal to 8 units. (check the first picture)

the circumference of the base is C=2πR=16π units=16*3.14 units = 50.24 units.

Answer:  <span>a cylinder with a circumference of about 50 units

2. 
Rotating the equilateral triangle around line a, produces a cone with base radius equal to half of one side of the triangle, that is r=10mm.

(check picture 2)

The circumference is </span>C = 2πr=<span>C = 2*3.14*10=62.8 mm

Answer: </span><span>a cone with a base circumference of about 63 mm</span>
