Answer:
Step-by-step explanation:
Given
Jar contains 4 white and 4 black marbles
We randomly select 4 marbles out of which 2 are white and 2 are black
Probability that 2 white and 2 black marbles are selected is
The process is continue for n trails until we choose the correct order
i.e. we have to fail in n-1 trails
For exact n selection Probability is given by
Well maybe because the only thing that is different is the - and +
Answer:
(2a, b )
Step-by-step explanation:
Given the endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is
[ 
(x₁ + x₂ ), (y₁ + y₂ ) ]
Here (x₁, y₁ ) = N(2a, 2b) and (x₂, y₂ ) = P(2a, 0), thus
midpoint = [ (2a + 2a), (2b + 0 ) ] = (2a, b )
Answer:
k=4
Step-by-step explanation:
First, we can subtract 3k on both sides. It is ultimately easier to start by subtracting the term with a variable. This would result in 45=5k+25. Then, we can subtract 25 on both sides to get closer to isolating k. This becomes 20=5k. We can then divide by 5 on both sides. This means that k=4.
