The formula C(n, r)= \frac{n!}{r!(n-r)!}, where r! is 1*2*3*...r


is the formula which gives us the total number of ways of forming groups of r objects out of n objects.


for example, given 10 objects, there are C(10,6) ways of forming groups of 6, out of the 10 objects.


<span>Thus, there are C(6, 3) many ways of forming different triples out of 6.</span>


C(6, 3)= \frac{6!}{3!(6-3)!}=\frac{6!}{3!3!}=\frac{6\cdot5\cdot4\cdot3!}{3!3!}=\frac{6\cdot5\cdot4}{3!}=\frac{6\cdot5\cdot4}{3\cdot2\cdot1}=5\cdot4=20


Answer: A.20

HELP ME PLZZZZZZZZZZZZ
Llana [10]

Answer:

157.5 square feet

Step-by-step explanation:

If an inch is 3 feet, then

3.5 inches = 10.5 feet (3.5*3)

5 inches = 15 feet (5*3)

The area of a rectangle is length times width so...

10.5*15 = 157.5

How much is the number 727731000 in percent form
tankabanditka [31]

Answer:

72773100000%

Step-by-step explanation:

"Percent" means "per 100" or "over 100". So, to convert 727731000 to percent we rewrite 727731000 in terms of "per 100" or over 100.

Multiply 727731000 by 100/100. Since 100/100 = 1, we are only multiplying by 1 and not changing the value of our number.

7277310001×100100=72773100000100

72773100000/100 is 72773100000 over 100 and means 72773100000 per 100. 72773100000 "per 100" means 72773100000 "percent" or 72773100000%

Therefore, we have shown that

727731000 = 72773100000%

Simplified Conversion:

Multiply by 100 and add the percent sign %

727731000 × 100 becomes 72773100000%

Shortcut Conversion:

Move the decimal point 2 places to the right and add the percent sign %

727731000 becomes 72773100000%

Olegator [25]

Answer:

44

Step-by-step explanation:

if she had 10 left at the end and you add the other half from lunch which is 12, then that gives you 22. Since before lunch she had half (22), all you gotta do is add the other half which is 22. 22+22=44 and that's your answer.
