Answer:
Step-by-step explanation:
The PDF of X is
The PDF of Y is
The means of X and Y are respectively,
so we can see that the larger the parameter, the smaller the mean. Hence the PDF of Z = min(X, Y) is an exponential with the largest parameter of the two.
Therefore, the PDF of Z is
Y = 3.5x
24= 3.5x
the train will be ride 6 times each day
and there are 7 days in a week
so multiply 6 and 7
=42
Answer:
So far we have looked at linear systems of equations in which the lines always intersected in one, unique point. ... When we graph them, they are one line, coincident, meaning they have all points in common. This means that there are an infinite number of solutions to the system.

Answer:
62.4 cm squared
Step-by-step explanation:
8^2-4^2=48
The square root of 48 is 6.928
7*2.928=48.497
(6.928*4)/2=13.856
48.497+13.856= 62.353 or 62.4
7-6x you are multiplying what’s in the () then comparing like term
