Answer:
It defines 1280 possible outcomes
Step-by-step explanation:
A can take on one of 20 possible values.Then, B can take on one of 64 possible values
The form to choose these pairs of outcomes are
(Possible values from A) x (Possible values from B) = 20 x 64 = 1280
Also the sum of these 1280 pairs of values must be equal to 1 because P(A,B) it is a joint distribution of probability.
We sum this 1280 pairs of values because A and B are discrete random variables.Otherwise we would use integrals.
Answer:
175 miles apart.
Step-by-step explanation:
This is because 2 goes into seven 3 times and half of 50 is 25 so for 1 inch it would be 25 miles. 50+50+50+25=175 miles.
Answer:55.227
Step-by-step explanation:
Given data
mass
=13lb
spring stretches by
=4.5in=0.375 ft
g=
Now Spring constant K
mg=kx
k=
For critical damping 

and 

substituting values

c=55.227 lb.sec/ft
