Answer:
a) P(A')=0.7.
b) P(B')=0.75.
c) P(C')=0.4.
d) d) Therefore, we conclude that are A and B mutually exclusive events.
Step-by-step explanation:
From task we know that are:
P(A)=0.3
P(B)=0.25
P(C)=0.6
Therefore, we get calculate the next probabilities:
a) P(A')=1-P(A)
P(A')=1-0.3
P(A')=0.7.
b) P(B')=1-P(B)
P(B')=1-0.25
P(B')=0.75.
c) P(C')=1-P(C)
P(C')=1-0.6
P(C')=0.4.
d) Therefore, we conclude that are A and B mutually exclusive events.

The difference of cubes is defined as
The given expression is
It can be written as
Using the property of exponent, the above expression can be written as
This is a difference of cubes.
Therefore the correct option is 1.
Answer:
270
Steps:
Divide 360 by 4 to find 1/4 of the black shoes.
360/4= 90
Multiply by 3 to find 3/4 of the shoes.
90*3=270
Answer:
Only side length and perimeter of one face
Step-by-step explanation:
Given is a cube with measures given in inches.
For a cube
Volume = s^3 where s = side
Hence volume and side are not having linear relation
Perimeter of 1 face = 4s and area =s^2
Obviously 4s and s^2 cannot have linear relationship as degree is diferent
Surface area of cube = 6s^2 but volume = s^3 both have different degrees of s and hence cannot have linear relation
Area of 1 face = s^2 and surface area = 6s^2
THus we get Surface area = 6(area of 1 face) hence can have linear relationship
side length =s and volume = s^3 so cannot have linear relaionship
Side length =s and perimeter = 4s thus having linear relation.
Hence answers are
side length and perimeter of 1 face
area of 1 face and surface area
