A pipe is manufactured according to a process that produces 1 defective pipe per 5000 pipes produced. All pipes produced are subject to an x-ray inspection. 99.9% of all defective pipes fail the inspection (are correctly identified as defective). 0.2% of good pipes fail the inspection (are incorrectly identified as defective).
1)What is the probability that a randomly-selected pipe will fail the inspection? (E.g. enter 50% as 0.50.)
2) What is the probability that a pipe that passes the inspection is defective? (E.g. enter 50% as 0.50.)
3) What is the probability that a pipe that fails the inspection is good? (E.g. enter 50% as 0.50.)

Protein 1 and RNA A are mixed in equimolar ratios and observed in a spectrophotometer with a 1 cm path length. The absorbance reading at 260 nm (A260) is 1.23. What would you anticipate A280 being for this sample?
3 mL of Protein 1 and 0.2 mL of RNA A were mixed to obtain the reading in Part A. What were the starting concentrations of Protein 1 and RNA A (in μM).

Part 1. Single-tone Modulation a –Write the code for an m-file (script) to generate a single tone FM signal. The modulating (message) signal is a single tone signal with frequency 1kHz and the carrier frequency is 20kHz. Vary the modulation index as m=0.2; 0.5; 1; 5 and 10. Plot your original message signal and the modulated signal for each value of m. Discuss the results. Use cosine function to define the message signal.
b- Repeat the part above only that this time generate a single tone PM signal. Compare the plots in parts a and b.

We are studying the corrosion rate between a piece of copper and a piece of zinc by dipping them in water and using a DMM to measure the conductivity. In the first test electric potential was found, then the electrical current was found. My question is how to find corrosion rate? Given the equation Nzinc= I / 2(96485.33), I being the electrical current in amperes. I just want to know really if the information we obtained is enough, maybe could you work it out using theoretical value. potential= 1 volt and current= 0.2 amps?
Please show work,
Thanks

Q8. One store notes that the probability of some type of error in a telephone order is 0.2. A supervisor randomly selects telephone orders and carefully inspects each one.
(2pts) What is the probability that the third telephone order selected will be the first to contain an error?
(3pts) What is the probability that the supervisor will inspect between two and six (inclusive) telephone orders before finding an error?
(3pts) What is the probability that the inspector will examine at least seven orders before finding an error?
(4pts) Suppose the first four telephone orders contain no errors, what is the probability that the first error will be on the eighth order or later?

A five-year bond with a yield of 11% (continuously compounded) pays an 8% coupon at the end of each year. a) What is the bond’s price? b) What is the bond’s duration? c) Use the duration to calculate the effect on the bond’s price of a 0.2% decrease in its yield. d) Recalculate the bond’s price on the basis of a 10.8% per annum yield and verify that the result is in agreement with your answer to (c).

A) Given 37ul of a 100 mg/ml stock solution of Bovine Serum Albumin (BSA), diagram the most accurate procedure so you end up with at least 500ul each of 5ug/ul, 0.5 ug/ul, and 0.05 ug/ul working solutions of BSA.
B) Using the BSA working solutions created above, how much and which concentration would you pipet into three different centrifuge tubes so you end up with 20 ug, 2 ug, and 0.2 ug of BSA? (Note: remember to stay within the accurate range of your pipetman.)

In the mass-pulley system below, the pulley is yo-yo shaped; i.e. consists of a lightweight axle (on which the string rests) with a radius of 2 cm connecting two 4 cm radius disks, each with a mass of 50 g. The coefficient of kinetic friction between the 500g block and the surface is μk = 0.2. When the system is released, the 200 g block will begin to travel upwards.
