Answer:
The probability of getting a black pen from the bag is 13.5%.
Step-by-step explanation:
To determine the percentage probability that a black pen will be obtained from the bag, the following calculation must be performed:
12 + 20 + 5 = 37
37 = 100%
5 = X
(5 x 100) / 37 = X
500/37 = X
13.5 = X
Thus, it is determined that the totality of pens is 100%, and through a cross multiplication the percentage of the 5 black pens with respect to the total of pens is obtained.
Therefore, the probability of getting a black pen from the bag is 13.5%.

Answer:
x = -3
Step-by-step explanation:
f(x) = 4x + 11
f(x) = -1
Substitute -1 for f(x)
-1 = 4x + 11
Subtract 11
-12 = 4x
Divide by 4
-3 = x
x = -3
