Use Soh Cah Toa. Soh(sin) is the Opposite side divided by the Hypotenuse side so in this case 21/20. Since we need the angle here we would use the inverse of sin. Your equation is Sin(x)=Opposite/Hypotenuse=21/20=1.05
Now solve sin(x)=1.05
Re-arange into
X=sin^-1 (1.05) but since you can’t have a inverse sin of a number more than one it is inconclusive or no answer

For which function is f(x) equal to f-1(x)?
Readme [11.4K]
Let's solve for f.
y=f−1x
Step 1: Flip the equation.
f−x=y
Step 2: Add x to both sides.
f−x+x=y+x
f=x+y
Answer:
f=x+y

La probabilidad de que el estudiante A apruebe un examen de MM-100 es 0.6, la probabilidad de que apruebe un estudiante B es 0.4
ivanzaharov [21]

Answer:

0.5 = 50% probabilidad de que apruebe el estudiante B dado que el estudiante A aprueba.

Step-by-step explanation:

La probabilidad condicional :

P(B|A) = \frac{P(A \cap B)}{P(A)}

En el cual:

P(B|A) es la probabilidad de que ocurra el evento B, dado que A sucedió.  

P(A \cap B) es la probabilidad de que ocurran tanto A como B.  

P(A) es la probabilidad de que ocurra A.

En esta pregunta :

Evento A: Estudiante A aprueba.

Evento B: Estudiante B aprueba.

La probabilidad de que el estudiante A apruebe un examen de MM-100 es 0.6

Entonces P(A) = 0.6

La probabilidad de que ambos estudiantes aprueben es 0.3

Entonces P(A \cap B) = 0.3

¿Cual es la probabilidad de que apruebe el estudiante B dado que el estudiante A aprueba.?

P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.3}{0.6} = 0.5

0.5 = 50% probabilidad de que apruebe el estudiante B dado que el estudiante A aprueba.
