(NOT A MULTIPLE CHOICE)

Vsevolod [243]

9514 1404 393

Answer:

a, b, c --- all not representative

Step-by-step explanation:

The question posed by the engineer is "are residents of the city in favor of ...".

The only representative sample is one from a pool that includes all residents of the city—not just those who (a) use the road, (b) live along the road, or (c) own homes.

Additional comment

The engineer may want to refine the question. As posed, it would include children, homeless, and/or institutionalized residents of the city as well as drivers and tax-payers. In inclusive cultural traditions, "residents of the city" may also include animals, plants, water, air, and other holders of spiritual energy.

A corporation must appoint a president, chief executive officer (CEO), chief operating officer (COO), and chief financial off

Travka [436]

Answer:

There are 524,560 ways that the committee can be appointed.

Step-by-step explanation:

There are 9 different positions, a president, 3 officers and five committee members.

P - O1 - O2 - O3 - C1 - C2 - C3 - C4 - C5

There are 17 candidates, any of them can be president. So P = 17.

All of the others can be an officers. So O1 = 16, O2 = 15(17 subtracted by the president and O1), O3 = 14.

The officers can be committee members, so, C1 = 16, C2 = 15, C3 = 14, C4 = 13, C5 = 12.

How many different ways can the committee be appointed?

This is the sequence C1...C5:

$N = 16*15*14*13*12 = 524,560$

There are 524,560 ways that the committee can be appointed.
