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.
Answer:
m = 72.9 grams
Step-by-step explanation:
Given that,
The density of a cube, d = 2.7 g/mL
Side of the cube, l = 3 cm
The volume of the cube is :
Since, 1 mL = 1 cm³
Mass per unit volume is equal to the density of an object.
So, the mass of the cube is 72.9 grams.
Answer:
x=14/9
Step-by-step explanation:
I’ve done these questions before and i’ve gotten confused because I have trouble with nagative numbers but i’ve gotten better st it. It’s -5
The first one should be x - y <= 25. Since there are 25 OR fewer available, depending on who is out sick or on vacation.
