Answer:
it b
Step-by-step explanation:
20 total marbles....7 are green
probability on first draw is 7/20...and since the marble was not replaced, the probability on the second draw is 6/19. And since they cant happen at the same time, we multiply
7/20 * 6/19 = 42/380 which reduces to 21/190
Answer
B
Step-by-step explanation:
Multiply all the Number of Board Games by 3.5. It is the same as the Price already showed on the graph. So, the correct answer is B.
Answer:
The answer to your question is (-1, 4) The lines cross in one point so they have only one solution.
Step-by-step explanation:
Data
Equation 1 x - 4y = -17
Equation 2 y = 4x + 8
Solve for y
Equation 1 y = -x/-4 - 17/-4
y = x/4 + 17/4
Equation 2 y = 4x + 8
See the graph below
These lines cross in point (-1, 4), so that is the only one solution.
If the lines were the same line they would have infinite solutions
