Answer:
8
Step-by-step explanation:
A and B are dependent events.
The general probabilities of each event to happen separately is 36% for event A and 25% for event B. When considering that Chris passes one before passing the other, indicates that whether he gets the first light open or not will affect if he gets the other one also open or not. This can even be seen by noticing how the probability of Chris getting both red lights is 9%, a much inferior probability then considering both lights separately which means that one event has influence over the other.
Answer:
x = 1/2 or 0.5
Step-by-step explanation:
Subtract 2 from both sides of the equation
x + 2 - 2 = 5x -2
Simplify
x = 5x -2
Subtract 5x from both sides of the equation
x = 5x -2
x - 5x = 5x - 2 - 5x
Solution
x = 1/2

Answer:
The expression that shows how long the two machines will operate simultaneously is:

Step-by-step explanation:
We know that:
x: hours to manufacture a deck of cards for machine A
y: hours to manufacture a deck of cards for machine B
z: hours that machine A operates alone
The number of decks manufactured only by machine A is:

So, the remaining decks are given by:

Then, the combined rate of machines A and B would be:

The work-rate formula is:

Hence, the time that the two machines work simultaneously is:
