6. A sporting goods store receives an order of 100 baseball caps, of which 22 are green. If 1 of
Taya2010 [7]

Answer:

\text{A. }39/50

Step-by-step explanation:

The probability that a randomly selected cap will not be green is equal to the number of non-green caps divided by the total number of caps.

Since there are 100 caps total and 22 are green, there must be 100-22=78 non-green caps.

Divide this by the total number of caps (100) to get the probability that a randomly selected cap will not be green:

\frac{78}{100}

Simplify by dividing both the numerator and denominator by 2:

\frac{78}{100}=\boxed{39/50}

For this case we first write the equation of which we will use:
 I (db) = 10log (l / l)
 We substitute the value of l.
 We have then:
 l = 10 ^ 8lo
 Substituting in the given equation:
 I (db) = 10log ((10 ^ 8lo) / lo)
 Rewriting:
 I (db) = 10 * log (10 ^ 8)
 I (db) = 80
 Answer:
 I (db) = 80
