Answer:
Step-by-step explanation:
We have that:
In which P(a) is the probability of a but not b and is the probability of both A and B.
By the same logic, we have that:
Also
P(A or B) is
Events A and B are mutually exclusive
This means that
A)80 B)100 C)120 D)300

Answer:
B.
Step-by-step explanation:
First, let's start from the parent function. The parent function is:
The possible transformations are so:
,
where a is the vertical stretch, b is the horizontal stretch, c is the horizontal shift and d is the vertical shift.
From the given equation, we can see that a=1 (so no change), b=3, c=-3 (<em>negative </em>3), and d=3.
Thus, this is a horizontal stretch by a factor of 3, a shift of 3 to the <em>left </em>(because it's negative), and a vertical shift of 3 upwards (because it's positive).
