Answer:
Events E and F are independent.
Step-by-step explanation:
E = {multiple of 3} = {3, 6, 9, 12}
P(E) = 4/12
F = {even number} = {2, 4, 6, 8. 10, 12}
P(F) = 6/12
E and F = {even and multiple of 3} = {6, 12}
P(E∩F) = 2/12
In order for two events to be independent the following relationship must be true:
Testing this property:
The relationship holds true, thus events E and F are independent.
Hey!!
The Answer is option B
as (2x-3)(2x+3)
=4x²-9
Answer S seems the best way to show that its equal. Correct me if I’m wrong please.
"A student" doesn't register for 46,140 credits, unless he wants to be very very busy.
If ALL of the students on campus register for 46,140 credits, then many colleges
would estimate the number of full-time students by using the formula
f = n / 15 = 46,140 / 15 = <u>3,076</u> students.
That's not the formula for 'n'. 'n' is the total number of credits for the semester,
and the question tells you what 'n' is. Knowing 'n', the formula helps you find 'f'.
