Answer: The expected duration for gathering system requirements using three-point method is 8 days.

We obtain the same answer when we use the Simple Average method and the PERT method.

We follow these steps while arriving at the answer.

We have the following information from the question:  

Optimistic Value (O) -  4 days (best estimate of time taken to complete the task)

Most Likely Value (M) – 8 days (realistic estimate of time taken to complete the task)

Pessimistic Value (P) – 12 days (worst estimate of time taken to complete the task)

There are two formulas we can use to determine the expected duration by using the three-point estimation method.

  1. <u>Simple Average method:</u> We use the following formula under this method.

         E_{SA} = \frac{O+P+M}{3}

         E_{SA} = \frac{4+12+8}{3}

         E_{SA}  = 8 days  (\frac{24}{3} )

       2. <u>PERT method</u>. The formula for this is:

          E_{PERT} = \frac{O+P+4M}{6}  

          E_{PERT} = \frac{4+12+(4*8)}{6}  

          E_{PERT} = \frac{48}{6}

           E{PERT} = 8 days

soldier1979 [14.2K]

Answer: Railways - the first industrial revolution, the Internet - the second, the technological - the oboe, the steam engine - the beginning, the telegraph - the first, the Feedback loops - second, The flying shuttle the first, The possibility of traveling from coast to coast in the US in under a wee - the first.

Explanation:

  • The Industrial Revolution brought about textural changes in people's lives, in everyday life, in the economy, in production. It went through several stages and always brought with it certain technological advances that made life easier for people. We link railways and the development of rail transport to the first industrial revolution. With steam technology, the first trains were launched and later this technology spread to the whole world. The emergence of the Internet is tied to the second half of the 20th century. It is a technology that has completely transformed the world, and without which life, today is almost impossible. When it comes to the technological revolution, it is still happening today. In this context, we bind it to both stages of the revolution. The advent of steamboats has been part of the technological revolution since the beginning of the 19th century, just like the advent of the Internet in the second half of the 20th century. The steam engine is part of the first technological revolution. Thanks to James Watts, transportation of people and goods was much faster and easier. The telegraph is part of the first technological revolution. The development of electricity has formed the basis for the electric telegraph. In 1832 Samuel Morse succeeded in developing the first stable and straightforward electrical messaging system, and in the following year received a patent for the invention.
  • The first real electric telegraph connected London and Birmingham and was built in 1838. The first operational amplifier to match its name was created by electronic tubing and built-in Bell's laboratories, United States, during 1941. This is a technology that we connect to backlinks and is part of another technological revolution. The invention of hydrogen, invented by the English physicist Henry Cavendish in 1767, solved the question of balloon filling. After many attempts by French physicist Jacques Charles, using a new invention to dissolve the rubber, he constructed a 380 m3 balloon with a bulletproof, hydrogen-filled shell that had a gas vent. The first steamboat to make a profit on sailing was built in 1807 (and patented in 1809) by the American Robert Fulton. However, the new boats were built even before the end of the 18th century.

NISA [10]

Answer:

20,300 pounds

Explanation:

<u>Purchases Budget for February - Pounds</u>

Material required in Production                                              19,900

Add Opening Materials Inventory (19,900 x 20%)                  3,980

Total                                                                                         23,880

Less Closing Materials Inventory (17,900 x 20%)                 (3,580)

Budgeted Purchases                                                              20,300

If the Fed lowers the required reserve ratio, __________ in the banking system will remain unchanged but __________ will rise. T
adell [148]

Answer: c. reserves; excess reserves; increase

Explanation: The reserve ratio (cash reserve ratio) is determined by a country's central bank (Federal Reserve in this case) as an important monetary policy tool to increase or decrease the economy's money supply. As such, it is the percentage of a bank's deposits that it must keep in cash as a reserve rather than invest with or lend out.

The reserves in the banking system would remain unchanged when the Fed lowers the required reserve ratio. However, the excess reserve (funds that a bank keeps back beyond what is required by regulation) would rise that would in most instances, lead to an increase in the money supply (due to increases in new loans and checkable deposits).
