Using the binomial distribution, there is a 0.2740 = 27.40% probability that exactly 4 of them say job applicants should follow up within two weeks.

For each manager, there are only two possible outcomes, either they say that job applicants should follow up within two weeks, or they do not say it. The opinion of a manger is independent of the opinion of any other manager, hence the binomial distribution is used to solve this question.

The formula for the probability of x successes is:

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

The parameters are given by:

In the context of this problem, the parameters are given as follows:

n = 7, p = 0.64.

The probability of exactly 4 saying that applicants should follow up within two weeks is P(X = 4), hence:

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 4) = C_{7,4}.(0.64)^{4}.(0.36)^{3} = 0.2740[/tex]

It is True to state that Arcs AB, BC, CD, DE, EF, FA in the circumscribed hexagon are all equal. See the explanation below.

In geometry, a hexagon is a six-sided polygon. A regular hexagon is one in which the lengths of all the sides and the measurements of all the angles are identical. The sides of a regular hexagon are therefore equivalent.

Allow point P to be the hexagon's and circle's center.

The dimension of arc AB is the same as the measure of central angle APB, which are both 360/6 = 60 degrees. This also applies to the other arc measurements. The whole 360-degree circle is divided into six equal parts, each measuring 60 degrees.

As there are 28 rows and in each row has 22 seats, then, the estimate of  the total income from the ticket sales equals to $4,989.60.

In a general sense, a total income means the gross income from all sources less certain deductions such as expenses, allowances and reliefs. But in the question context, it means the revenue, which is the total amount of income generated by the sale of goods and offering of services related to the primary operations of the business.

Given data

Cinema have 28 rows

Cinema have 22 seats per row

Each ticket cost 8.10

Total Income = $8,10 * 28 rows * 22 seats

The final price of the refrigerator after the additional 15% discount is $170

Given

The original sale price of the refrigerator  = was $250

Given a 20 % discount on the original price, the new sale price would be as follows

Sale price = original price - Discount

                 = [tex]250-(\frac{20}{100} )250[/tex]

Sale price = $200

After this an additional 15% discount is given on new sale price.

So again deducting the discount from the sale price we get,

Sale price = 200 - discount(15%)

                = [tex]200-(\frac{15}{100} )200[/tex]

Sale price = 170

The machine will take 7 minutes to fill one box. Hence, table A. represents the correct relationship between the number of minutes the machine fills boxes and the number of boxes it has filled.

Boxes filled by machine in 35 minutes = 5 boxes

So, the number of boxes the machine fills in each minute = Time taken to fill 5 boxes/ Number of boxes filled

= 35/5

= 7 minutes

Time taken by machine to fill one box = 7 minutes

Time taken to fill two boxes = 14 minutes

Time taken to fill three boxes = 21 minutes

Time taken to fill four boxes = 28 minutes

The given composition as a single translation is (x,y)→(x+1,y+2) .

In the question,

two translation are given , we have to write the composition of two translation in a single translation ,

we choose arbitrary points (x,y) in the tile , and find the horizontal and vertical shift in the coordinates of point after both translations .

let A(x,y) be an arbitrary point in the tile

So , by the first translation

"move 2 tiles right and 3 tiles up" ,

after first translation, the coordinates are  A'(x+2,y+3)

The second translation "you move 1 tile left and 1 tile down" ,  will map A'(x+2,y+3) to

A"(x+2-1 , y+3-1)

= A"(x+1 , y+2)

Therefore , the single translation rule for the composition is (x,y)→(x+1,y+2)    .

A reflection is referred to as a twist in geometry. A reflection is the mirror image of shape . A line, called the line of reflection, will agree an image to reflect without change it. When all of the points in a figure are evenly spaced apart from one another, the two figures are said to reflect each other. The reflected picture should have the same size and shape as the original, but it faces the opposite way. Changes in position during contemplation may also result in translation. Pre-image and image are terms used to refer to the same thing in this context. ABC and A'B'C are used to represent the pre-image and image, respectively.

Answer:

x = 2

Step-by-step explanation:

Use distributive property:

3(2x+4) = 24

3*2x + 3*4 = 24

6x+12 = 24

6x = 12

x = 2

The unknown angles are as follows:

complementary angles are angles that sum up to 90 degrees.

in other words, When two angles add to 90°, we say they "Complement" each other.

Therefore,

9x + 2x + 7 = 90

11x = 90 - 7

11x = 83

x = 83 / 11

x = 7.54

Therefore,

∠1 = 9(7.54) = 67.9°

∠2 = 2(7.54) + 7 = 22.08°

Supplementary angles are angles that sum up to 180 degrees.

Therefore,

3x + 8  + 9x = 180

12x + 8 = 180

12x = 180 - 8

12x = 172

x = 172 / 12

x = 14.3

Hence,

∠1 = 9(14.3) = 129°

∠2 = 180 - 129 = 51°

Vertically opposite angles share the same vertex.  Vertically opposite angles are equal.

Therefore,

9x = 3x + 9

9x - 3x = 9

6x = 9

x = 9 / 6

x = 3 / 2

x = 1.5

Therefore,

∠1 = 9(1.5) = 13.5°

∠2 = 13.5°

Applying the concept of the or operation, the solution to the given inequality is as follows:

r < -5/8 or r ≥ 3/8.

Considering two data-sets, the or operation between them is the set composed by all the elements that belong to at least one of the data-sets.

In the case of an inequality, the data set is represented by the intervals.

The first inequality is:

0.5r + 3 < 7/4.

0.5r < 7/4 - 3

r/2 < -5/4 (as -3 = -12/4)

r < -5/8.

The second inequality is:

-r + 3/4 ≤ 3/8

-r ≤ 3/8 - 3/4

-r ≤ -3/8 (as 3/4 = 6/8)

r ≥ 3/8 (multiply by -1, hence the signal also changes).

As the intervals do not intersect, the solution to the inequality is given as follows:

r < -5/8 or r ≥ 3/8.

Be remined for the second expression affects the signs of all the terms inside the brackets.

the coordinates of a point P that lies along the directed line segment from E (-5, 5) to F (-2,-2) and partitions the segment in the ratio of 2 : 1.5 is (- 23 / 7 , 1).

We are given a line segment formed by joining the points:

E (- 5, 5)

F (- 2, - 2)

We need to find the coordinate of a point P which divides this line segment in the ratio 2 : 1.5

Now, we can also write this ratio as:

4 : 3

The formula for finding the coordinate of point P is:

x = (m x₂ + n x₁) / (m + n)

y = (m y₂ + n y₁) / (m + n)

Substituting the values in the formula, we get that:

x = 4(-2) + 3(-5) / 4 + 3

x = - 8 - 15 / 7

x = - 23 / 7

y = 4(- 2) + 3(5) / 4 + 3

y = - 8 + 15 / 7

y = 7 / 7 = 1

So, point P = (- 23 / 7 , 1)

Therefore, we get that, the coordinates of a point P that lies along the directed line segment from E (-5, 5) to F (-2,-2) and partitions the segment in the ratio of 2 : 1.5 is (- 23 / 7 , 1).
