If two events are dependent on each other you have to multiply the probability of the first event times the probability of the second event.
first count all the marbles here there are 21
you are asked about picking two green marbles there are 7 out of the 21 total.
The first event would be 7/21
The second event would be 6/20 (since you didn't replace and you took out a green one)
now multiply your two fractions together:
and you get 1/10.
2, 6, 18, 54, 162, 486...
Start with the number 2.
And continue with that pattern from there.
Answer:
1.452/0.6 simplified is 1.000/1.0

Answer:
So slope 1 would be positive
Slope 2 would be negative
Slope 3 would be zero
Step-by-step explanation:
If the slope is moving up from left to right, then it is positive
If the slope is moving down from left to right, then it is negative
If the slope is a vertical line and is not moving left/right, then it is undefined
If the slope is a horizontal line and is not moving up/down, then it is zero
So slope 1 would be positive because it is moving up from left to right.
Slope 2 would be negative because it is moving down from left to right.
Slope 3 would be zero because it is a horizontal line that is not moving up or down.
Hope this helped!
