Step-by-step explanation:
Elimination method involves making two coefficients equal in order to get rid of one variable and finding the other.
Graphing method is using the intercepts the plotting your points on a graph.
Substitution method involves using change of subjects and then substituting the equation for the variable.
The two equations represent the different speeds (60 and 40) that two cars are traveling and the distances where they began (5 and 40). The solution represents the time(x) when they have traveled the same distance. Graphically it is the point where they intersect.
Other scenarios would be any time you are comparing two things like cost to drive two different cars or internet services.
Systems of equations help us see each situation, in this problem the time and distance a car travels then relate it to another car's distance traveled at the same times.
Answer:
A continuous probability distribution having a rectangular shape, where the probability is evenly distributed over an interval of numbers is a(n) __uniform__________ distribution
Step-by-step explanation:
Given that there is a continuous probability distribution having a rectangular shape, where the probability is evenly distributed over an interval of numbers
Since the pdf is rectangular in shape and total probability is one we can say all values in the interval would be equally likely
Say if the interval is (a,b) P(X) = p the same for all places
Since total probability is 1,
we get integral of P(X)=p(b-a) =1
Or p=
this is nothing but a uniform distribution continuous defined in the interval
A continuous probability distribution having a rectangular shape, where the probability is evenly distributed over an interval of numbers is a(n) __uniform__________ distribution
