The amount of flight time between failures of an airplane engine is exponentially distributed with mean 700 hours. If the engine is inspected every 100 hours of flight time, what is the probability that the engine will fail before it is inspected? (Round your answer to two decimal places.)

For a 0.25 pfor b o.3pp (0.25+0.3)=0.28

Idon't see any graph, however the graph of the function : f(x) = x²-2x+3 is a parabola: 1) open upward (since a> 0)2) it intersects y-axis in 3 (y=3)3) its axis of symmetry is x = +1 ( -b/2a)4) it's minimum is y = -2, so its vertex is (1,-2)5) it doesn't intersect the x-axis since discriminant < 0
