Answer:
P(A or B) = 25%
Step-by-step explanation:
P(A and B) = 30%
P(A) = 40%
P(B) = 15%
Apply given formula:
P(A or B) = P(A) + P(B) - P(AB)
= 40%+15+-30%
= 25%

Here we have the following rational function:

So the graph of this function is shown in the First Figure below. Let's define another function which is a parent function:

Whose graph is shown in the second figure below. So we can get the graph of f from the graph of g this way:
Step 1. Shift the graph 3 units to the left:

Step 2. Shift the graph 2 units down:

Finally, the features of the graph of f are:
The graph of this function comes from the parent function g and the transformations are:
- A shifting 3 units to the left
Answer:
$38-
Step-by-step explanation:
15% = $57
57 ÷ 3 = 19%
15 ÷ 3 = 5
100 ÷ 5 = 20
