first you put this equation into y=mx+b form then you look at the slope of the equation. if both of the slopes are same then its parallel.
Answer: y=-3
Step-by-step explanation:
It is the horizontal line that "splits" the graph.
Given that a parking lot contains 100 cars, k of which happen to be lemons.
This is a conditional probability question.
Let event A be that a car is tested and event B be that a car is lemon.
The probability that a car is lemon is given by

The probability that a car is tested is given by

The probability that a car is lemon and it is tested is given by

For a conditional probability, the probablility of event A given event B is given by:

Therefore, the probability that a car is lemon, given that it is tested is given by.
a way of writing down very large or very small numbers easily.
Answer:
R(p) = -4p^2 + 300p when p=20.
R(p) = -4(20)^2 + 300(20)
R(p) = -1600 + 6000
R(p) = 4400
The mass when p=20 years is 4400.
