Answer:

It’s equivalent.

Step-by-step explanation:

Collect like terms: 4x+12 = 4(3+x)

Expand brackets: 4x+12 = 12+4x

La siguiente tabla presenta las frecuencias absolutas y relativas de las distintas caras de un dado cuando se simulan 300 lanzam
noname [10]

La opinión correcta es la de Camila que argumenta que la frecuencia relativa de la cara con el #6 será un valor cercano a 0,166.

<h3>Qué es la frecuencia relativa?</h3>

La frecuencia relativa es un término matemático que se utiliza en la estadística para referirse al número de veces que un evento se repite durante un experimento.

Por otra parte, es necesario aclara que la frecuencia relativa no se modifica en gran medida si se aumenta el número de veces de una prueba, debido a que la probabilidad de ocurrencia de este evento va a ser la misma.

De acuerdo a lo anterior, Camila tiene razón debido a que considera que el valor de la frecuencia relativa no se modifica en gran medida entre 300 o 600 lanzamientos de los dados.

Nota: Esta pregunta está incompleta porque no está la tabla. No obstante, la puedo responder basado en mi conocimiento previo.

how many ways are there to win the jackpot? how many ways are there to match 5 of 6 numbers? how many ways are there to match 4
musickatia [10]

The number of ways to  match 5 of 6 numbers is 6 ways

The number of ways to  match 4 of 6 numbers is 15 ways

The number of ways to  match 3 of 6 numbers is 20 ways

To calculate number of ways to match 5 of 6 numbers we have to use to formula:

nCr =\frac{n!}{(n - r)! . r !}

6C5=\frac{6!}{(6-5)! . 5!}

6C5=\frac{6!}{(1)! . 5!}

6C5=\frac{6.5.4.3.2.1}{1.5.4.3.2.1}

6C5=\frac{6}{1}

6C5= 6 \ ways

∴ 6 ways are to match 5 of 6 numbers

To calculate number of ways to match 4 of 6 numbers we have to use to formula:

nCr =\frac{n!}{(n - r)! . r !}

6C4=\frac{6!}{(6-4)! . 4!}

6C4=\frac{6!}{(2)! . 4!}

6C4=\frac{6.5.4.3.2.1}{2.1.4.3.2.1}

6C4=\frac{30}{2}

6C4= 15 \ ways

∴ 15 ways are to match 4 of 6 numbers

To calculate number of ways to match 4 of 6 numbers we have to use to formula:

nCr =\frac{n!}{(n - r)! . r !}

6C3=\frac{6!}{(6-3)! . 3!}

6C3=\frac{6!}{(3)! . 3!}

6C3=\frac{6.5.4.3.2.1}{3.2.1.3.2.1}

6C3=\frac{120}{6}

6C3= 20 \ ways

∴ 20 ways are to match 3 of 6 numbers
