1. You will receive $100 per year for 10 years. The discount rate is 10%. What is the present value of this stream? 2. Using the previous information, assume now the 100 will increase at a 5% per year from year 1. What is the new present value? 3. Now assume compute the present value for the same information using a perpetuity without and with growth. Compare the 4 present values. What would you rank those? (Please explain step by...

A grinding machine in an auto-parts factory prepares axles with a target diameter of μ = 40.33 millimeters (mm). The machine has some variability, so the standard deviation of the diameters is σ = 0.006 millimeter. The machine operator inspects a random sample of 9 axles each hour for quality-control purposes and records the sample mean diameter x . Calculate the mean and standard deviation of the sampling distribution of x . ___________________________ _________ Please help!

A factory finds that, on average, 10% of the bulbs produced by a given machine will be defective for certain specified requirements. If 8 bulbs are selected at random from the day's production of this machine, find the probability a.) exactly 2 will be defective. b.) that 2 or more will be defective and c.) that more than 5 will be defective.

A) Machine A produces an average of 10% of defective parts. Machine B produces on average...

A) Machine A produces an average of 10% of defective parts. Machine B produces on average twice as many defective parts as machine A. Machine C produces on average three times more defective parts than machine B. Here are 8 bags of parts from A, 2 bags of parts from B and 1 bag of coins from C. We randomly take a coin from one of the bags itself also taken at random. She is defective. 1. What is the...

3.32. Quality Control. An automatic machine in a small factory produces metal parts. Most of the time (90% according to long-term records), it produces 95% good parts, while the remaining parts have to be scrapped. Other times, the machine slips into a less productive mode and only produces 70% good parts. The foreman observes the quality of parts that are produced by the machine and wants to stop and adjust the machine when she believes that the machine is not...

A small auto parts store has a single counter with one employee. Customers arrive at the counter at the rate of 10 per hour according to a Poisson distribution. The employee can handle 20 customers per hour and service times are exponentially distributed. Calculate (A) The probability that a customer finds an empty counter in the auto parts store (no customers waiting or being served) (B) The average number of customers waiting in the que at the auto parts store (i.e.,...
