C.
By plugging in the numbers into the equation, 8 = 250(k), we can determine that 8 ÷ 250 = 0.032.
Answer:
The solution to the system of equations be:
x = 2, y = 4
Step-by-step explanation:
Given the system of equation
y - 2 = x
y = 3x - 2
substitute y = 3x - 2 in the equation y - 2 = x
y - 2 = x
(3x - 2) - 2 = x
3x -2 -2 = x
3x - 4 = x
add 4 from both sides
3x - 4 + 4 = x + 4
3x = x + 4
subtract x from both sides
3x - x = x + 4 - x
3x - x = 4
2x = 4
divide both sides by 2
2x/2 = 4/2
x = 2
For y = 3x - 2, plug in x = 2
y = 3x - 2
y = 3(2) - 2
y = 6 - 2
y = 4
Therefore, the solution to the system of equations be:
x = 2, y = 4
Answer:
34.5% probability that the jury returns a guilty verdict
Step-by-step explanation:
We have these following probabilities:
The defense attorneys have a 70% chance of convincing the jury that the police either contaminated or planted some of the key evidence.
In this case, there is a 15% probability that the jury will return a guilty verdict.
There is also a 100 - 70 = 30% of not convincing the jury that the police either contaminated or planted some of the key evidence.
In this case, 80% probability of the jury returning a guilty verdict.
What is the probability that the jury returns a guilty verdict?
15% of 70% and 80% of 30%. So

34.5% probability that the jury returns a guilty verdict
