A submarine has three navigational devices but can remain at sea if at least two are working. Suppose that the failure times are exponential with means 1 year, 1.5 years, and 3 years. Formulate a Markov chain with states 0 D all parts working, 1, 2, 3 D one part failed, and 4 D two failures. Compute E0T4 to determine the average length of time the boat can remain at sea

think about it deeply and passionately about this property

i am sorry

point a is the center of the circle that passes through points e, f, and g and the center of the circle that passes through points x, y, and z.

start with a line segment pq that we will copy. mark a point r that will be one endpoint of the new line segment. set the compasses' point on the point p of the line segment to be copied. adjust the compasses' width to the point q. the compasses' width is now equal to the length of the line segment pq.

step-by-step explanation:

ruth is 6 years old

step-by-step explanation:

6 + 24 = 30,   so 6/30 = .2  

if you do 1/5 it also equals .2, so that is the answer.
