Answer:
Step-by-step explanation:
Answer:
(-(7-9))(z)-6z= 8(-6+2)
Simplify
-(-2)(z) -6z =8(-6+2)
Multiply 8*-6 and 8*2
2z -6z= -48+16
Combine like terms
2z+-6z =-32
-4z=-32
Divide both sides by -4
z=8

Answer: The required probability is 0.6.
Step-by-step explanation:
Since we have given that
It is uniformly distributed between 40 minutes and 90 minutes,
Probability that her trip will take longer than 60 minutes would be

here, a = 40, b = 90, α = 60

Hence, the required probability is 0.6.
