Answer:
16/25
Step-by-step explanation:
Given
Number of green marbles = 9
Number of White marbles = 17
Total number of marbles = 26
Probability of picking a white marble = 17/26
When a white marble is picked without replacement,
Probability of picking another white marble after first picking a white marble
= 16/25
= 0.64
This is because the total number of marbles would have reduced from 26 to 25 and the number of white marbles from 17 to 16.
Answer:
The width of the rectangular room =x= 8
Step-by-step explanation:
Given: A rectangular room is twice as long as it is wide, and its perimeter is 48 meters.
To find: The width of the room.
Solution: Let the width of the rectangular room= x meters, then the length of the rectangular room will be = 2x.
Now, Perimeter of rectangular room=2(l+b)
⇒48=2(2x+x)
⇒24=3x
⇒x=8 meters
Then, the width of the rectangular room =x= 8 meters and the breadth of the rectangular room=2x=2(8)=16 meters.
Answer:
-26
Step-by-step explanation:
1. Replace the x with 6
2. Multiply -4 by 6 to get -24
3. Subtract 2 from -24 to get -26
