Ms. White has 15 students in her first grade class. Troy is the line leader for the week, and Mackenzie is last because she was the line leader last week. In how many different ways can Ms. Whites class line up for lunch?

Answers

Answer 1
Answer: The first place and 15th place are already decided, so we have to find the number of
different ways that the other 13 students can line up, in the places from #2 to #14.

2nd place can be any one of 13 people.  For each of those . . .
3rd place can be any one of 12 people.  For each of those . . .
4th place can be any one of 11 people.  For each of those . . .
.
.
.
13th place can be any one of 2 people.  For each of those . . .
14th place has to be the one student who is left.

Total number of ways that 13 students can line up in places #2 through #14 is

(13 x 12 x 11 x 10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1)

That number is called "thirteen factorial".  The number is 6,227,020,800 .

When you write it in math, you write it like this:    13!

Answers

Answer:

  (C)  32

Step-by-step explanation:

The difference of 4th powers can be factored as ...

  a^4 -b^4 = (a -b)(a +b)(a^2 +b^2)

For a=13, b=11, this becomes ...

  13^4 -11^4 = (13 -11)(13 +11)(13^2 +11^2)

  = 2(24)(169 +121)

  = 2(8·3)(290) = 2^5 · 3 · 5 · 29

The largest power of 2 that is a factor is 2^5 = 32.

What is an arithmetic operation?

The four fundamental operations of arithmetic are addition, subtracting, multiplying, and dividing two or more numbers. Included is the study of integers, especially the order of operations, which is essential for all other aspects of mathematics, notably algebra, information management, and geometry.

As per the data given in the question,

7.2 × 4= $28.8

$28.8 - 10=18.8

which means that she saves $18.8 per week.

18.8 × 12 = 225.6

She has collected 225.6 dollars over 12 weeks.

225.6 × 0.25 = 56.4

she received $56.4 from her grandparents,

$56.4 + $225.6 = $282

she has $282.

7.2 times 4=28.8-10=18.8
she saves 18.8 dollars per week.
18.8 times 12=225.6
after 12 weeks she has saved 225.6 dollars
225.6 times 0.25=56.4
her grandparents giver her 56.4 dollars
56.4+225.6=282
she has 282 dollars

How many different combinations are there of the digits 46987?

Answers

Answer:

1,00000,00,00

Step-by-step explanation:

The digits 46987 can be arranged in 120 unique combinations using the permutation formula 5! (5 factorial), accounting for all possible orders of these digits.

While organizing the digits 46987, there are 120 unmistakable mixes conceivable. Still up in the air by ascertaining the factorial of the quantity of digits (5!), yielding 120. Every game plan brings about a remarkable mix. For instance, 46987, 78694, and 98746 are among the changed stages.

The idea of changes has expansive applications, going from arithmetic to software engineering, where request matters. In combinatorics, the investigation of counting and game plan, changes assume an essential part. These 120 mixes grandstand the adaptability of revamping only five digits.

Showing the dramatic development in potential outcomes as the quantity of digits increments. This numerical standard impacts fields like cryptography, where producing one of a kind successions is significant for security. Generally, the changes of 46987 outline the charming and strong parts of numerical control and request.
