Define a generic method called checkorder() that checks if four items are in ascending, neither, or descending order. The method should return -1 if the items are in ascending order, 0 if the items are unordered, and 1 if the items are in descending order. The program reads four items from input and outputs if the items are ordered. The items can be different types, including integers, strings, characters, or doubles.

There can be 432 Types of Combinations for a 4-digit number beginning with 1 that has exactly two identical digits

What is permutation and combination?

[tex]$11xy,\qquad 1x1y,\qquad1xy1$[/tex]

Because the number must have exactly two identical number digits,[tex]$x\neq y$[/tex], [tex]$x\neq1$, and $y\neq1$[/tex]. Hence, there are [tex]$3\cdot9\cdot8=216$[/tex]  number of this form.

Now suppose that the two identical digits are not 1. Reasoning similarly to before, we have the following possible combination:

[tex]$1xxy,\qquad1xyx,\qquad1yxx.$[/tex]

Again,,[tex]$x\neq y$[/tex], [tex]$x\neq1$, and $y\neq1$[/tex]. There are [tex]$3\cdot9\cdot8=216$[/tex] numbers of this form.

Thus the answer is 216+216=432

The number of men on the sight - seeing tour was  22 .

In the question ,

it is given that,

the ratio of women to children on the tour is = 5 : 2

let the number of men in the sight seeing tour =  m

let the number of women in the sight seeing tour =  w

let the number of children in the sight seeing tour =  c

So , w/c = 5x/2x

also the ratio of children to men is 5/11 ,

c = 5y and m = 11y

the number of women on the sight seeing tour is less than 30 ,

which is 5x < 30 ,

x < 6

but we have c = 2x and 5y ,

and since c is a multiple of 5 , 2x also has to be a multiple of 5 ,

earlier we got , x < 6 ,

Now using x =5 , we get c = 2*5 = 10

and so , 10 = 5y

y = 2 ,

So , the number of men = 11y = 11*2 = 22 men

Therefore , the number of men are 22 .

The given question is incomplete , the complete question is

On a certain sight-seeing tour, the ratio of the number of women to the number of children was 5 to 2. What was the number of men on the sight-seeing tour?

Given sequence:

Find the common ratio, the ratio of two consecutive terms:

or

The length and width of the rectangular poster are 23 inches and 7 inches respectively.

Here we have to find the dimensions of the length and width of the rectangular.

Data given:

length of the rectangular poster is 2 more than three times its width.

Let us assume that the width of the rectangular is x.

The area of the poster = is 161 inches²

So by this, we get the length 3x + 2.

width = x

length = 3x + 2

The formula of the area of the rectangular:

Area = length × width

161 = (3x+ 2) × x

161 = 3x² + 2x

3x² + 2x - 161 = 0

3x² + 23x - 21x - 161 = 0

x(3x + 23) - 7( 3x + 23) = 0

(3x + 23) ( x -7)= 0

x = -23/3, 7

As the length cannot be negative so we get the value of x as 7

width = 7 inches

length = 3x + 2

= 3×7 + 2

= 21 + 2

= 23inches

Therefore the length and width are 23 inches and 7 inches respectively.

Horizontal lines are parallel so as suggested in:

1. Vertical angles are congruent, so 5a = 115.

2. Alternate interior angles are congruent, so b - 12 = 65.

3. Corresponding angles are congruent and linear angle pairs sum up to 180, so (b-12) + 65 = 180.

However, alternate interior angles are congruent,

as stated in 2nd suggestion too, so the sum is not 180 but 130.
