Step-by-step explanation:
If you have two marbles in a bag and you are choosing the marbles randomly twice, then we can look at fractions.
Each time, you have a 0.5 chance of picking the silver marble. After you pick that, you have another 0.5 chance of picking the silver marble again.
This applies with any combination.
This means that the probability of you getting two silvers in a row is 0.25.
Since the marbles are the same size and nothing is stopping you from choosing one, this probability applies to all combinations possible.
Hope this helped!
Square needs to have all equal sides and length and width are the same.
So sqrt the area.
sqrt 121 = 11
11 feet is the length of one side, square has 4.
So
11 * 4 = 44
The perimeter of a square (whose area is 121 feet) is 44 feet.
Answer:
the chance at getting 9 is 17% and then 50% for the coin
Step-by-step explanation:
Step-by-step explanation:
r-5r-6s+8s-15
-4r+2s-15
= 2s-4r-15
M1= -5 , m2 = 5 inorder to get this you move the constant to the right take the root of both sides separate the solutions and you should get m1= -5, m2 =5
