irakobra [83]

Answer: 1/6

Step-by-step explanation: There are 4 primes. So the probability for the first draw is 4/9. Since the card is not replaced, the second probability is 3/8. 3/8 * 4/9 is 12/72, which simplifies into 1/6.

Et f(x) = x2 + 6 and g(x) g(x) x+8/x . Find ( g o f)(­ -7)
earnstyle [38]

Answer:

A

Step-by-step explanation:

A function composition is where one function is substituted within another function and is written g(f(x)). Here we will substitute f(x) into g(x). For g(f(-7)), we substitute -7 for x.

\frac{x^2+6+8}{x^2+6}

Now substitute -7 for x.

\frac{x^2+6+8}{x^2+6} = \frac{(-7)^2+6+8}{(-7)^2+6}=\frac{49+6+8}{49+6}=\frac{63}{55}

y = 68° because y + z + 13 = 180°
