The lengths of a professor's classes has a continuous uniform distribution between 50.0 min and 52.0 min. If one such class is randomly selected, find the probability that the class length is between 50.1 and 51.3 min. P(50.1 < X < 51.3) =

1/10

Step-by-step explanation:

The total possible time is 2.0 minutes long

between 50.1 and 51.3 is 0.2 minutes

0.2/2.0 = 1/10

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !

i believe the correct answer is b.
