A newly employed worker takes 15 minutes to complete the first task while she takes 12.75 minutes to complete the second task. How long the worker would take to complete the tenth task?
For the first task, time required = 15 minutes
Time required for the second task = 12.75 minutes.
Since the time taken to do a task is always positive and it reduces by each additional task undertaken, we assume that the time taken by the new employed worker reduces geometrically with each additional task undertaken, we calculate the value of 'r', the amount by which the reduction takes place.
where t stands for the number of task undertaken, t = 1, 2, 3, 4, .....
Thus, for the tenth task, the worker takes 3.4742 minutes.

BONUS The time it takes a worker on an assembly line to complete a task is exponentially distributed with a mean of 7.8 minutes. What is the probability that it will take a worker less than 5 minutes to complete the task? What is the probability that it will take a worker between 4 and 11 minutes to complete the task? What is the probability that it will take a worker greater than 7.5 minutes to complete the task? a....

What is the probability that it will take a worker less than 8 minutes to complete the task? b.What is the probability that it will take a worker between 8 and 12 minutes to complete the task?
Suppose you measure the number of minutes it takes an employee to complete a task, where the maximum allowed time is 5 minutes, and each time is rounded to the nearest minute. Data from 130 employees is summarized below. How long did it take most employees to complete the task? time: 1, 2, 3, 4, 5 frequency: 25, 40, 50, 35, 30
3. The amount of time it takes to complete a task is normally distributed with a mean of 34 minutes and a standard deviation of 4 minutes. If I take a sample of 24 people how many of those 24 people on average will take over 37 minutes to do the task?
If Professor Laurie Macdonald takes 15 minutes to grade the first exam and follows an 80% learning curve, how long will it take her: a) to grade the 25th exam? b) to grade the first 10 exams?
w pay OLUU for the upgrade. 6(15%) A researcher worker wants to determine the average time it takes a mechanic to rotate the tires of a car and she wants to be able to assert with a 95% confidence that the mean of her sample is off by at most 0.50 minutes. It is known that o = 1.6 minutes and the time of rotation is normally distributed. How large a sample size will she have to take? Frequently used...

A Girl Scout is taking a 12.00-km hike to earn a merit badge. While on the hike, she sees a cliff some distance away. She wishes to estimate the time required to walk to the cliff. She knows that the speed of sound is approximately 343 meters per second. She yells and finds that the echo returns after approximately 2.4 seconds. If she can hike 1.00 km in 6.7 minutes, how long would it take her to reach the cliff?...
