Answer:

$a) \: - 2x + 4 = 10 \\ 4 = 10 + 2x \\ 4 - 10 = 2x \\ - 6 = 2x \\ \frac{ - 6}{2} = x \\ - 3 = x \: or \: x = - 3 \\ \\ b) \: \frac{3}{4x} = 2 \\ 3 = 2 \times 4x \\ 3 = 8x \\ x = \frac{3}{8} \\ 0.375 = x \: \: or \: x = 0.375$

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
