Answer: It costs $5.52 to Sam to buy 12 stamps.
Step-by-step explanation:
Given: Sam paid $8.28 for 18 stamps.
Thus, the cost of 18 stamps = $8.28
Then the cost of 1 stamp=
Thus, the cost of 1 stamp=$0.46
With the same rate , the cost of 12 stamps=
Therefore, the cost of 12 stamps= $5.52
hence, it costs $5.52 to Sam to buy 12 stamps.
Probability helps us to know the chances of an event occurring. The correct option is A.
<h3>What is Probability?</h3>Probability helps us to know the chances of an event occurring.
Dependent events are those events in which the outcome of the first event affects the outcome of the second event. The statement that is correct about the dependent event is that the probability of all dependent events can be calculated using the "OR" formula P(A+B) =P(A) +P(B)-P(A and B).
Hence, the correct option is A.

Given the exponential function f(x) and the logarithmic function g(x) the true statement is given as
Option A.
This is further explained below.
<h3>What is logarithmic function g(x)?</h3>Generally, The exponential function is a kind of mathematical function that may be represented using the notation f(x)=exp or ex. The word, unless otherwise mentioned, usually refers to the function of a real variable that has a positive value; however, it may be extended to complex numbers or applied to other mathematical objects such as matrices or Lie algebras.
In conclusion, the Exponential equation x = ay is defined as analogous to the logarithmic function y = logan. Only when (x = ay), (a > 0), and (a 1) does (y = logan). It is referred to as the logarithmic function of base a. Think about what it implies when the exponential function is inverted: x = ay.
