In the word "SASSAFRAS", there 2520 permutations can be formed.

<h3>Permutation : </h3>

A permutation is a mathematical technique that determines the number of possible arrangements in a set when the order of the arrangements matters.

The order of arrangement in permutation is in linear form.

In the given word is “SASSAFRAS”. There are total 9 letters in which some letters appears several times, that is

 S = 4 times.

 A = 3 times.

 F = 1 times.

 R = 1 times.

We can the number of permutation to arrange this letter with the help of :

<em>nPr = n</em>! / (<em>n </em>- <em>r</em>)!

<em>n</em>P<em>r</em> = Permutation

<em>n</em> = Total number of objects

<em>r</em> = Number of objects selected

'!'     =     Factorial

<h3>Factorial : </h3>

Factorial (noted as “!”) is the product of all positive integers less than or equal to the number preceding the factorial sign. For example, 3! = 1 x 2 x 3 = 6.

So, <em>n</em>P<em>r  </em>=  9!/(4!) (3!) (1!) (1!)

              = (9×8×7×6×5×4×3×2×1)/(4×3×2×1)×(3×2×1)×(1)×(1)

              = 3,62,880/ 24×6×1×1

              = 3,62,880/144

              = 2,520

Hence, 2520 permutations can be formed from the word 'SASSAFRAS'.

Organize from least to greatest
dedylja [7]

Answer:

y=31x/15 < y=27x/13 < y=15x/7 < y=13x/6 < y=11x/5 < y=21x/9 (=7x/3) < y=19x/8

Step-by-step explanation:

since all equations base on a linear, simple expression of x, we can simply compare the fractions.

in general, the bigger the number at the bottom, the smaller the individual fraction. that is our first indicator.

we then notice that many fractions represent the value of 2 plus one fraction.

31/15 = 2 1/15

27/13 = 2 1/13

15/7 = 2 1/7

13/6 = 2 1/6

11/5 = 2 1/5

the only exceptions are 21/9 and 19/8

but 21/9 is actually 7/3 = 2 1/3

and fits therefore into the list above.

that leaves 19/8 = 2 3/8.

the list above can be sorted based on the single fraction at the end (remember, the bigger the number at the bottom, the smaller the value). so, from least to greatest :

2 1/15 (31/15)

2 1/13 (27/13)

2 1/7 (15/7)

2 1/6 (13/6)

2 1/5 (11/5)

2 1/3 (7/3 = 21/9)

where did now 2 3/8 fit in ?

well, 3/8 is almost 1/2 (so, relatively big), and we start our comparison with the biggest number in the list so far :

1/3 (from 2 1/3).

what is bigger - 1/3 or 3/8 ?

let's find the smallest number that can be divided by 3 and by 8. that would be 24. so now we bring both fractions to the same base of 24.

1/3 = 8/24

3/8 = 9/24

=> 3/8 > 1/3

and therefore, 19/8 is the largest value and at the end of the list.
