Solution:
Independent Events:
Consider an experiment of Rolling a die, then getting an even number and multiple of 3.
Total favorable outcome = {1,2,3,4,5,6}=6
A=Even number = {2,4,6}
B=Multiple of 3 = {3,6}
A ∩ B={6}
P(A)=, P(B)=
P(A ∩ B)=
So, P(A)× P( B)==P(A ∩ B)
Hence two events A and B are independent.
Option (c). the outcome of one event does NOT determine the outcome of the other event
Answer:
C on edge or the outcome of one event does NOT determine the outcome of the other event
Step-by-step explanation:
To be clear, the given relation between time and female population is an integral:
Answer:
Required equation
Step-by-step explanation:
Given : After the booster club sold 40 hot dogs at a football game, it had $90 in profit. After the next game, it had sold a total of 80 hot dogs and had a total of $210 in profit.
To find : Which equation models the total profit,y,based on the number of hot dogs sold,x ?
Solution :
Let x = total number of hot dogs sold
y = total profit from total sales of hot dogs
We can model the equation: ......[A]
where, y is the total profit and x is the number of hot dogs sold.
Profit for 40 hot dogs = $90 profit
The system of equation form is
......[1]
Profit for 80 hot dogs = $210 profit
The system of equation form is
.......[2]
The solution of equations [1] and [2]
Subtract equation [1] and [2]
Substitute in equation [1]
Substitute the values in equation [A]
This is the required equation models the total profit based on number of hot dogs.
