WILL MARK BRAINLIEST

Mathematics
1 answer:
Nina [5.8K]3 years ago
8 0

Answer:

randomly choosing a marble from a bag, replacing it, and choosing again

rolling a number cube, rolling again, and trying to match the first roll

Explanation:

In an independent event, getting a certain outcome once does not change the probability of getting the same outcome again.

The second option (about the coins) is NOT independent because if you pull out a dime on your first try, there are fewer dimes in your pocket and you are less likely to pull out a dime the second try. The third option (about drawing a number) is also NOT independent for the same reason: you don't put the number back into the hat after drawing it out, so there's fewer numbers the second time and the probability is different.

Son proporciones.<br> cual es el resultado de :x/2,5=y/5 si x+y=6
omeli [17]

Respuesta: x/2,5=y/5=4/5=0,8


x/2,5=y/5

Multiplicando ambos lados de la ecuación por 5:

5(x/2,5)=5(y/5)→2x=y→y=2x

Sustituyendo y por 2x en la ecuación x+y=6:

x+2x=6

Resolviendo para x: Sumando términos semejantes:

3x=6

Dividiendo ambos lados de la ecuación entre 3:

3x/3=6/3

x=2

Sustituyendo x por 2 en la formula y=2x

y=2(2)→y=4

Determinando la proporción:

x/2,5. Sustituyendo x por 2:

2/2,5

Multiplicando numerador y denominador por 2:

2*2/(2,5*2)=4/5

La proporción es 4/5=0,8

Si lo hacemos con y:

y/5

Reemplazando y por 4:

4/5=0,8 (la misma proporción)

What is rational number and how do you convert 4/33 as decimal
mr Goodwill [35]
A rational number includes fractions (3/4), integers (-2,-1,0,1,2), and whole numbers (0,1,2,3,4,5).

To convert a fraction into a decimal, you divide the numerator by the denominator. In your case, 4/33 as a decimal is 0.1212121212...etc..
