Stels [109]

Answer:

a) 0.1535

b) 0.4866

c) 0.8111

Step-by-step explanation:

The probability that the next call come within the next t minutes is:

  • p(t) = 1 -e ^{- t/3}

According to this model,

a) the probability that a call in comes within 1/2 minutes is p(t) = 1 -e ^{- (1/2)/3} =0.1535

b) the probability that a call in comes within 2 minutes is  p(t) = 1 -e ^{-2/3} =0.4866

c) the probability that a call in comes within 5 minutes is  p(t) = 1 -e ^{-5/3} =0.8111

A train traveled 210 mi in 3.5 h to its first stop. It then continued on traveling another 130 mi in 2.5 h.
11111nata11111 [884]

Answer:

56.7 ​ mi/h​


Step-by-step explanation:

The formula for average speed is:

Average Speed = \frac{TotalDistance}{TotalTime}


Thus we have:

Average Speed = \frac{210+130}{3.5+2.5}\\=\frac{340}{6}\\=56.66 mph


<em>Rounding to the nearest tenth, we have </em>

Average Speed = 56.7 mi/h
