Answer:
A.) x / 3 = 12 ----> x = 12(3) ----><em> </em><em>x = 36</em>
B.) 2x + 3 = 20 ----> 2x = 17 ----> x = 17/2
C.) 4/3x = 10/3 ----> x = 10/3 x 3/4 ----> x = 30/12 = 5/2
D.) -4x = -24 ----> x = -24/-4 ----> x = 6
E.) 2(x-4) = 10 ----> 2x - 8 = 10 ----> 2x = 18 ----> x = 9
F.) -0.5x + 1.1 = -2.9 ----> -0.5x = -4 ---> x = -4 / -0.5 ----> x = 8
Answer:I think it’s C
Step-by-step explanation:
Answer: OPTION D.
Step-by-step explanation:
<h3>
The compete exercise is: "James used substitution to solve this system of equations. Which could be the result of his first step</h3><h3>
"</h3>
Given the sytsem of equations:

1- Solve for one of the variables from any equation and substitute it into the other equation.
2- Solve for the other variable in order to get its value.
3- Substitute this value back into one of the original equations. and find the value of the other variable.
In this case youu can observe that the second equation is already solved for "y", therefore, in order to use the Substitution Method, the first step is: Substitute the second equation into the first one.
Therefore, the equation that could be the result of James' first step is:

Usando probabilidad condicional, se encuentra que hay una probabilidad de 0.0186 = 1.86% que la persona esta realmente autorizada para ingresar.

Probabilidad Condicional
En que:
- P(B|A) es la probabilidad de que ocurra el evento B, dado que A sucedió.
es la probabilidad de que ocurran tanto A como B. - P(A) es la probabilidad de que ocurra el evento A.
En este problema:
- Evento A: Persona rechazada.
- Evento B: Autorizada.
La probabilidad de una persona ser rechazada es:
de 95% = 0.95(autorizada).
de 5% = 0.05(non autorizadas).
O sea:

La probabilidad de una persona estar autorizada y ser rechazada es:

¿Cuál es la probabilidad que la persona esta realmente autorizada para ingresar?



Probabilidad de 0.0186 = 1.86% que la persona esta realmente autorizada para ingresar.
