Answer:
tell me this question in a more clearer way then ill message the answer
Step-by-step explanation:
To calculate this probability we must take into account that there is the same probability that any of the 3 urns is chosen.
This probability is:
P (U1) = P (U2) = P (U3) = 1/3
Urn 1 contains 7 black and 3 red marbles
Urn 2 contains 2 black and 8 marbles network
Urn 3 contains 5 black marbles and 5 red marbles.
The probability of obtaining a black marble in Urn 1 is 7/10.
The probability of obtaining a black marble in Urn 2 is 2/10
The probability of obtaining a black marble in Urn 3 is 5/10.
Then we look for the probability of obtaining a black marble from urn 1 or a black marble from urn 2 or a black marble from urn 3. This is:
P (U1yB) + P (U2yB) + P (U3yB)
So:
(1/3) * (7/10) + (1/3) * (2/10) + (1/3) * (5/10) = 0,2333 + 0,0667 + 0,1667 = 0, 4667.
The probability that it is a black marble is 46.67%
Answer:
g(4) = -5, h(8)= 8, f(-2)= -7, g(-2)= 7
Step-by-step explanation:
It's pretty simple. The number in the parenthesis is the value of x.
Therefore, you look at the table, find the required function and the value of x that is given.
The number that is in the answers is the value of y.
Answer:
I believe that x is 12 1/3. I could be wrong.
P1 = (-4, 0)
P2 = (2,0)
From the information given, we can conclude that this is a vertical parabola that opens downwards.
Also we can see that the vertex is not (0,0)
Equation
(x - h)^2 = 4p(y - k)
To find the equation I need three point, to form 3 equations.
The values that I need to find are: h, k and p
