Answer:

d) 330

Step-by-step explanation:

The number of ways can a dance instructor send 4 of her 11 students to summer dance program is  C(11 , 4)

That is 11_{C_{4} } ways

by using formula n_{C_{r} } = \frac{n!}{(n-r)!r!}

now simplification

11_{C_{4} } = \frac{11!}{(11-4)!4!}

      = \frac{11X10X9X8X7!}{(7!)4X3X2X1}

after cancelling 7! and on simplification

   = \frac{11X10X9X8}{4X3X2X1}

after cancellation we get 330 ways

The number of ways can a dance instructor send 4 of her 11 students to summer dance program is 330

Find elapsed time between 7:10 am to 8:15am two way
Marianna [84]
First Way:
7: 10am to 8:00am = 50 mins
8:00am to 8:15am = 15 mins
Total = 50 min + 15 min = 65 mins = 1 hour 5 mins

Second Way:
7: 10am to 8:10am = 1 hour
8:10am to 8:15am = 5 mins
Total = 1 hour + 5 mins = 1 hour 5 mins

Answer : 1 hour 5 mins

The local operations manager for the Internal Revenue Service must decide whether to hire one, two, or three temporary tax exami
Helga [31]

Answer:

If she uses the Laplace criterion, the number of new examiners she will decide to hire is:

c. three

Step-by-step explanation:

a) Data:

Number of           Compliance

examiners     Low   Normal   High

One               50        50         50

Two              100        60         20

Three           150        70         -10

b) Outcome Calculations:

Number of                     Compliance

examiners            Low                      Normal                High

One              16.65 (50 *.333)     16.65 (50 *.333)     16.65 (50 *.333) =  50

Two              33.3 (100 *.333)      19.98 (60 *.333)      6.66 (20 *.333)  = 60

Three           49.95 (150 *.333)    23.31 (70 *.333)     -3.33 (-10 *.333) =  70

c) Decision:

Three has the highest payoff condition and is selected.

d) The Laplace criterion assumes that each compliance state is equally likely to happen.  Therefore, it assigns the same weight to each state of compliance.  Since there are three states of compliance, we shall assign each state a weight of 0.333.  The number of examiners that have the highest payoff condition is three, and therefore, the number "three" is selected.
