Answer:
B. Events A and B are mutually exclusive if A and B have no sample points in common.
Step-by-step explanation:
When two events( call them A and B) are mutually exclusive , it is impossible for them to happen together.
P(A and B) = 0
"The probability of A and B together equals 0 (impossible)"
Hence, the correct answer is B.
B. Events A and B are mutually exclusive if A and B have no sample points in common.

Answer:
50 cars and 25 bikes
Step-by-step explanation:
Given
Total wheels = 250
Required:
Number of cars and bikes
Let C represent Cars and B represents Bike
A car has 4 wheels and a bike has 2 wheels;
So,
Divide through by 2
---- Equation 1
The ratio of wheels of cars to wheels of bike is 1:2
Meaning that
1C = 2B
So, C = 2B
Substitute 2B for C in equation 1
Divide both sides by 5
Recall that C = 2B
So,
Hence, Anna has seen 50 cars and 25 bikes
Answer:
x= 4 or -10
Step-by-step explanation:
Okay, since she started with $100, then that would be a constant. So the function would start off with f(x)=?+100. Okay, now since she is depositing $25 PER month, then the 'x' varibale would be per month. So the function would be f(x)=25x+100. Now since you want to know the rate of change, just insert the x value as the month. For example, you want to know how much money she has on the 4th month, so you would substitute 4 with x --> f(x)=25(4)+100, which is f(x)=200
