If all possible rearrangements of the word REVISIONS are sorted alphabetically, the n-th word is VISIONERS. What is the remainder when n is divided by 100?
Answers
Answer:
75
Step-by-step explanation:
You want the remainder when n is divided by 100, where VISIONERS is the n-th word in the alphabetically-ordered list of the permutations of REVISIONS.
Lexicographical orderThe letters of the word REVISIONS are, in alphabetic order, are EIINORSSV. We notice there are two each of the letters I and S.
When the permutations of the letters of REVISIONS are written in lexicographical order, the list will first have all of the permutations beginning with E, then those beginning with I, and so on until the permutations beginning with S are exhausted.
Counting permutationsTo find the rank (number n) of the first permutation beginning with V, we must count the number of permutations ahead of it in the list. This will be the sum of the numbers of permutations beginning with E, I, N, and so on through S.
The straightforward way to do this is to consider the letters individually, and the number of permutations associated with each one. For example, the letters following E will be the 8 letters IINORSSV, which have two repeat pairs. The number of permutations of these 8 letters is 8!/(2!·2!) = 10080.
The next leading letter in the list is I, which can be followed by any of the letters EINORSSV, for a total of 8!/2! = 20160 permutations.
The letter N will be the next leading letter, and it will have a number of permutations equal to the number for the letter E, 10080.
At this point, we have exhausted 4 of the 8 letters that must precede V in the ordered list, and have counted 10080 +20160 +10080 = 40320 permultations. We notice this is, in effect, 10080 permutations per letter, the number of permutations of the letters not including V.
If we were to work through the remaining letters (including the repeated S), we would find the total to be 8·10080 = 80640 permutations before any starting with V.
Effectively, our formula for the number of added permutations preceding words matching up to the k-th letter of our target word is ...
p(9-k)!/q
where p is the number of letters in the (remaining) ordered letter list preceding the k-th letter of VISIONERS, and q is the factor that compensates for repeated letters among those remaining. "q" is the product of the factorials of the number of times a letter is repeated. For 2 letters, each repeated once, q = 2!·2! = 4.
Application of the formulaV is the 9th letter of EIINORSSV; there are 8 letters preceding, including 2 repeated twice. k=1, so there are 8·(9-1)!/(2!·2!) = 80640 permutations preceding ones starting with V.
I is the 2nd letter of EIINORSS; there is 1 letter preceding, including 2 repeated twice. k=2, so there are 1·(9-2)!/(2!·2!) = 1260 permutations preceding ones starting with VI.
S is the 6th letter of EINORSS; there are 5 letters preceding, including 1 repeated twice. k=3, so there are 5·(9-3)!/2! = 1800 permutations preceding ones starting with VIS.
I is the 2nd letter of EINORS; there is 1 letter preceding, with no repeats. k=4, so there are 1·(9-4)! = 120 permutations preceding ones starting with VISI.
O is the 3rd letter of ENORS; there are 2 letters preceding. k=5, so there are 2·(9-5)! = 48 permutations preceding ones starting with VISIO.
N is the 2nd letter of ENRS; there is 1 letter preceding. k=6, so there are 1·(9-6)! = 6 permutations preceding ones starting with VISION.
We note that the remaining letters, ERS, are in alphabetical order, so there are no additional permutations preceding VISIONERS.
RankThen the number of permutations preceding VISIONERS is ...
80640 +1260 +1800 +120 +48 +6 = 83874
and the rank of VISIONERS is 83875.
RemainderThe remainder when this is divided by 100 is 75.

Additional comment
The usual counting method goes into more detail than the one described here. For problems of reasonable size, it is often easier to count the permutations generated ahead of the one of interest using a "next permutation" function.
In the attachment, we generated them all, and searched for the one of interest.

Write two inequalities to compare a and b how do you know?
Answers
To compare two numbers, a, and b, we can write two inequalities:
a < b when a is less than b
a > b when a is greater than b.
What is inequality?Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.
We may write two inequalities to compare two numbers, a and b:
a < b
a > b
If a is less than b, then the first inequality is true and the second is false. If a is greater than b, then the first inequality is false and the second is true. Otherwise, if a and b are equal, then both inequalities are false.
We can determine which inequality is true by comparing the values of a and b and using the rules of inequality.
For example, if a=3 and b=5, then we can determine that a < b is true and a > b is false because 3 is less than 5.
On the other hand, if a=8 and b=2, then we can determine that a < b is false and a > b is true because 8 is greater than 2.

The division of the whole numbers is not closed under property as the division of whole number is not always a whole number.
A set has the closure property under a particular operation if the result of the operation is always an element in the set. If a set has the closure property under a particular operation then we say that the set is “closed under the operation.” The closure property of the division tells that the result of the division of two whole numbers is not always a whole number. Whole numbers are not closed under division that is a ÷ b is not always a whole number.

How do you solve two parallel lines crossed by a transversal?
Answers
When two lines are crossed by a transversal, a number of angle pairs are formed. The sum of the measures of these angle pairs can be used to solve for unknown angles in the diagram.
Here are some of the angle pair relationships that hold for two lines crossed by a transversal:
Alternate Interior Angles: Alternate interior angles are pairs of angles on opposite sides of the transversal, but inside the two lines. These angles are congruent (have the same measure).Alternate Exterior Angles: Alternate exterior angles are pairs of angles on opposite sides of the transversal, but outside the two lines. These angles are congruent.Corresponding Angles: Corresponding angles are pairs of angles on the same side of the transversal, but on opposite sides of the two lines. These angles are congruent.Using these relationships, you can set up equations to solve for unknown angles in the diagram. For example, if you are trying to find the measure of angle A, you might use the fact that corresponding angles are congruent to set up the equation "m<A = m<D". Then, you can use other angle pairs to find the measures of the other angles, and solve the system of equations to find the measure of angle A.

Part A
Which system ot equations can vevused to find the price of the shorts and t-shirts?
(use attachment)
Part B
how much did keegan pay for each t-shirt and each pair of shorts?
Answers
Part A
Adding the costs, [tex]2s+5t=49.50[/tex].
Since a pair of shorts costs twice as much as a T-shirt, [tex]s=2t[/tex].
The correct answer is option 3.
Part B
[tex]2(2t)+5t=49.50 \\ \\ 9t=49.50 \\ \\ \boxed{t=5.50} \imploes \boxed{s=11}[/tex]

The number of CDs that can be bought are { 5, 4, 3, 2, 1 }.
What is an inequality ?
A relationship between two expressions or values that is not equal to each other is referred to as "inequality" in mathematics. So inequality emerges from an imbalance.
Given, No. of CDs = x
A CD costs $11 and He has total $60.
So, According to the question,
No. of CDs × Cost of each CD ≤ 60
x × 11 ≤ 60
11x ≤ 60
x ≤ 60/11
Since the number of CDs can't be in fraction and The maximum CDs can be bought is 5.
So, The possible No. of CDs that can be purchased are { 5, 4, 3, 2, 1 }
