dedylja [7]

Answer:

The appropriate answer is "11 crimes".

Step-by-step explanation:

Let,

The number of crimes be "n".

Now,

⇒ P(solved \ at \ least \ one) = 1-P(solved \ none \ of \ n)

or,

⇒ 1-(0.8)^n>0.9

⇒       (0.8)^n

By taking log both sides, we get

⇒ n>=\frac{log(0.1)}{log(0.8)}

By putting the values, we get

⇒ n>=10.31

      n=11 \ crimes

Given that f(x) is even and g(x) is odd, determine whether each function is even, odd, or neither. (f • g)(x) = ? (g • g)(x) = ?
vekshin1

Answer:

<h2>(f · g)(x) is odd</h2><h2>(g · g)(x) is even</h2>

Step-by-step explanation:

If f(x) is even, then f(-x) = f(x).

If g(x) is odd, then g(-x) = -g(x).

(f · g)(x) = f(x) · g(x)

Check:

(f · g)(-x) = f(-x) · g(-x) = f(x) · [-g(x)] = -[f(x) · g(x)] = -(f · g)(x)

(f · g)(-x) = -(f · g)(x) - odd

(g · g)(x) = g(x) · g(x)

Check:

(g · g)(-x) = g(-x) · g(-x) = [-g(x)] · [-g(x)] = g(x) · g(x) = (g · g)(x)

(g · g)(-x) = (g · g)(x) - even
