Answer:
Equation would be x = - 4 .
Step-by-step explanation:
Given : vertical line passing through the point (−4, 2).
To find : Choose the equation of the vertical line .
Solution : We have given that point (−4, 2).
We know that vertical line always passes through the x axis .
Here, line passes through at x = -4 which has no slope .
Therefore , equation would be x = - 4 .
Answer:
If A and B are independent events, then the events A and B' are also independent. Proof: The events A and B are independent, so, P(A ∩ B) = P(A) P(B). From the Venn diagram, we see that the events A ∩ B and A ∩ B' are mutually exclusive and together they form the event A.
Answer:
Step-by-step explanation:
Given A and B are independent events, P(A and B) = P(A)*P(B)

Answer:
The constant of variation is k=5
Step-by-step explanation:
Proportions
A direct proportion is a relation between variables where their ratio is a constant value. This means that if y and x are proportional, then:
Where k is the constant of proportionality.
We know R varies directly with S. Their relationship is:
We also have when S=16, R=80. Thus:
Solving for k:
The constant of variation is k=5
Answer:
The answer is x ≤ 4
