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?

Step-by-step explanation:

Round 64.12 and 7.4 to whole numbers that divide nicely, and are CLOSE to the original numbers.

The normal distribution with a mean of 0 and a standard deviation of 1 is known as the standard normal distribution.

The usual normal distribution is then followed by the z variable. A value of the x variable's z variable, also known as the z-score of the x variable, indicates how many standard deviations from the mean it is.

The area under the normal distribution curve must be calculated that lies between

z=−1.56 and z=1.56

Using the standard normal table, the area is calculated as:

P(−1.56<z<1.56)

=P(z<1.56)−P(z<−1.56)

=P(z<1.56)−(1−P(z<1.56))

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.

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,

Find the slope of the function (m):

Slope (m) = change in B / change in t = (20 - 10) / (2 - 4)

Slope (m) = 10/-2
