We need to find the number of combinations of the 15 members taken 4 at a time:
15C4=\frac{15!}{4!11!}=\frac{15\times14\times13\times12}{4\times3\times2\times1}=1365

Alecsey [184]

Answer:

<em>134456</em>

Step-by-step explanation:

7^{6} = 7 · 7 · 7 · 7 · 7 · 7

Therefore, 7^{6} = 117,649

7^{5} = 7 · 7 · 7 · 7 · 7

Therefore, 7^{5} = 16,807

Arturiano [62]

Answer:

21) There is a 0% chance of picking a 13 in a deck of cards. <u>Impossible.</u>

If there is a 0% chance that something will happen then it is impossible.

22) There is a 50% chance of picking a red card in a deck of cards.<u> Equally likely.</u>

If there is a 50% chance that something will happen, it is equally likely that it will happen.

23) There is an 80% chance of snow tomorrow. <u>Likely or certain.</u>

If there is an 80% chance of something happening, it means that the chances of that thing happening good and the event is likely to occur.

24) There is a 20% chance of rain tomorrow. <u>Unlikely.</u>

A low chance of 20% means that something is unlikely to occur.

The number of employees for a certain company has been decreasing each year by 3%. If the company currently has 810 employees an
8090 [49]

Answer:

219 employees

Step-by-step explanation:

3% of decreasing rate of employees per year is calculated thus:

3\% \: of \: 810 \: employees

=  \frac{3}{100}  \times 810

= 24.3 \: employees \: per \: year

In 9 years,

= 24.3 \times 9

= 218.7 = 219 \: employees

Therefore, the number of employees for a certain company where decreasing rate of employees is 3% and continued to decrease for 9 years; and 810 employees are currently working is 219 employees. By implication, 810 + 219 = 1029 employees were working in the company 9 years ago.
