Answer:
a) 4.8
b) 2.96
c) 4.4
d) 1.44
e) 3.76
Step-by-step explanation:
What we will do is solve point by point, knowing the following:
Fx (x) = P (X <= x) = (x - 1) / 4
a) P (X <-a) = 0.95
Fx (a) = 0.95
(a -1) / 4 = 0.95
a = 1 + 0.95 * 4
a = 4.8
b) P (X <a) = 0.49
Fx (a) = 0.49
(a -1) / 4 = 0.49
a = 1 + 0.49 * 4
a = 2.96
c) P (X <a) = 0.85
Fx (a) = 0.85
(a -1) / 4 = 0.55
a = 1 + 0.85 * 4
a = 4.4
d) P (X> a) = 0.89
P (X <a) = 1 - 0.89 = 0.11
Fx (a) = 0.11
(a -1) / 4 = 0.11
a = 1 + 0.11 * 4
a = 1.44
e) P (X> a) = 0.31
P (X <a) = 1 - 0.31 = 0.69
Fx (a) = 0.69
(a -1) / 4 = 0.69
a = 1 + 0.69 * 4
a = 3.76
48.9 / 4 = 12.225
distance = 100m
time = 12.225 sec
v = d/t
The answer is 8.1799

Answer: Time = 1.5hours or 1 hour 30minutes
Step-by-step explanation:
Given;
Carrie can inspect a case of watch in 5 hours
if n represent the task,
Carrie's rate C = n/5
James' rate J = n/3
Their combined rate is=n/5 + n/3 = 8n/15
Carrie After working one hour, he would have completed n/5 of the task.
Therefore, the remaining fraction of task is 4n/5
To complete the remaining fraction of task by the two of them, the time taken can be given as;
Work done = rate × time
Time = workdone/rate
Workdone = amount of task remaining = 4n/5
rate combined= 8n/15
Time = (4n/5)/(8n/15)
Time = 1.5hours or 1 hour 30minutes
