Answer:
Ta có: P (
A
) P (
B
) = 0
,
12
. Vì P (
A
B
) = 0
,
2 ≠ 0
,
12 = P (
A
) P (
B
)
nên hai biến cố A và B không độc lập với nhau.

Step-by-step explanation:
15. If f(x) = 20x, adding a $10 fee for cleaning would be
g(x) = 20x + 10
The graph of g(x) is shifted 10 units up from the graph of f(x).
16. f(x) = 2x + 1
g(x) = (2x + 1) + 5
h(x) = 3f(2x + 1)
g(x) shifted f(x) 5 units to the right.
h(x) is 3 times steeper than f(x).
If this is the correct answer, then please give it the brainliest.
