9 block rhombuses would create 3 hexagons.

In order to increase the total number by three, a hexagon can be divided into a minimum of three rhombuses, each of which can be further divided into four rhombuses. With n being a positive integer, the result is 3n. The top two hexagons in this image are each divided into 8 and 10 rhombuses. The total number of rhombuses that can fit in a hexagon is not limited to multiples of three, given that the total number of rhombuses dividing a hexagon can be raised by three by quartering a single component rhombus. The amount might actually be any integer larger than 7.

The probability that marksman will hits the target at most 13 times is  27.92%.

The number of successes ("x") is the probability mass function for such binomial distribution.

P(X = x) = ⁿCₓ . pˣ . qⁿ⁻ˣ

We are interested in the likelihood that the target will be struck exactly five times, therefore the desired number of successes is five (i.e., x = 13).

P(X = 13) =  ¹⁵C₁₃. (0.89)¹³ (0.11)²

P(X = 13) = 0.2792

P(X = 13) = 27.92%

Thus, the probability that marksman will hits the target at most 13 times is  27.92%.

Answer:

D, AAS.

Step-by-step explanation:

So basically the a's and s' mean angle and side. this means that if there is a line on both of the triangles on one side this means that those sides of the triangle are congruent. this is the same case with the angles. if you were to have one congruent side inbetween two congruent angles, you would use ASA, which stands for angle side angle, to prove that the triangles are congruent. some more examples are:

side, side, angle =SSA.

angle, angle side = AAS. (the problem in question)

hope this helps :)

The answer is option C)

If two angles and a non-included side of one triangle are congruent to two angles and the corresponding non-included side of a second triangle, then the two triangles are congruent. This is the AAS congruence rule.

Given here in ΔVTY and ΔWYX

VY = WX , ∠VYT = ∠WXY and ∠VTY = ∠WYX

Therefore, by AAS congruence rule , we get  ΔVTY≅ ΔWYX

Accordingly, by the property of congruence of triangles we get

TV = YW

Hence, option C)  ΔVTY≅ ΔWYX by AAS, so TV = YW by def of ≅

The expression in the form of (a sin()) is 12 sin 6 sin (42). This is the simplified form of the original expression.

To simplify the expression 6 sin 6 6 cos 6 into an expression of the form (a sin()), we need to use the identity sin^2(x) + cos^2(x) = 1. We can rewrite 6 cos 6 as 6 sin (90-6) using the identity sin(x+y) = sin(x)cos(y) + cos(x)sin(y). Therefore, our expression becomes 6 sin 6 6 sin (84).
Now, using the identity sin(x-y) = sin(x)cos(y) - cos(x)sin(y), we can simplify further to get:
6 sin 6 6 sin (90-6)
= 6 sin 6 6 sin 6cos(84)
= 6 sin 6 (2 sin 6 cos 84)
= 12 sin 6 sin (42).
Therefore, the expression in the form of (a sin()) is 12 sin 6 sin (42). This is the simplified form of the original expression.
In summary, to simplify an expression to the form (a sin()), we need to use trigonometric identities and manipulate the expression until it is in the desired form. In this case, we used the identities sin(x+y) and sin(x-y) to simplify the expression 6 sin 6 6 cos 6 into the expression 12 sin 6 sin (42).

To approach this type of problem, you have to make a couple of reasonable assumptions - first, that each worker works at the same pace, and second, that the effort to build each wall is the same.

Next, figure out how much effort is required to build one wall. The effort is measured in “working days”. So, how many days does one worker need to build one wall, or how many workers would be required to build one wall in one day? We can calculate this by dividing the 25 worker days used to build five walls by the number of walls (5). So we need five worker days per wall.

(5 workers) x (5 days) = 25 worker-days;

25 worker days/5 walls = 5 worker days per wall.

With 100 workers, it will take five days to build 100 walls. Each worker will build one wall in 5 days. So it will also take 5 days for all 100 workers to build all 100 walls.

100 x 5 = 500 worker days;

500 worker-days / 100 workers = 5 days (answer)

Given parameters:

Number of pages Haley can read = \(\frac{5}{8}\) pages

Time to read the pages = \(\frac{2}{3}\) min

Unknown:

Number of pages that can be read in 1 min = ?

Solution:

To solve this problem let us find Haley's rate;

       Rate  = \(\frac{Number of pages Haley can read}{Time }\)

 Input the parameters and find the rate;

     Rate  = \(\frac{5}{8} / \frac{2}{3}\)

     Rate  = \(\frac{5}{8} x \frac{3}{2}\)

      Rate = \(\frac{15}{16}\) pages/min

Now that we know the rate;  

   In 1 min; number of pages Haley can read;

               Number of pages  = Rate x time

                Number of pages  = \(\frac{15}{16}\)  x   1  = \(\frac{15}{16}\)\(\frac{15}{16}\) pages

Haley can read pages \(\frac{15}{16}\)  in 1 minute.

The little league team called the Hawks has 7 brunettes, 5 blonds, and 2 red heads.

The entire little league division that The Hawks belong to has the same ratio of redheads to everyone else.

What is the total number of redheads in that division if the total number of players is 126?

Answer:

18 red heads

Step-by-step explanation:

We are told:

The little league team called the Hawks has 7 brunettes, 5 blonds, and 2 red heads.

Hence, we have the ratio

7: 5: 2

Adding up the ratios together

7 + 5 + 2

= 14

The total number of players is 126

Hence, the total number of redheads in that division is

2/14 × 126

= 18 red heads.

The inradius of the triangle of the given dimensions will be equal to the value 2.

To find the inradius of a triangle, we need to know the semi perimeter of the triangle, which is half of the perimeter. The perimeter of a triangle is the sum of the lengths of its sides. So, the semi perimeter of triangle ABC is (6+8+10)/2 = 12.

Now that we know the semi perimeter, we can use the formula for the inradius of a triangle:

inradius = √(s-a)(s-b)(s-c)/s

where a, b, and c are the lengths of the sides of the triangle and s is the semi perimeter.

Plugging in the values for a, b, c, and s, we get:

inradius = √(12-6)(12-8)(12-10)/12 = √(6)(4)(2)/12 = √48/12} = √4 = 2

Therefore, the inradius of triangle ABC is 2.

we can simplify |x + 3| to x + 3 when x is greater than 5.

The absolute value function |x| is defined as the distance of x from zero on the number line. This means that |x| is always non-negative, so it can be expressed as a non-negative number.

In this case, we are given that x > 5, which means that x is greater than 5. If we add 3 to both sides of this inequality, we get:

x + 3 > 5 + 3

x + 3 > 8

This tells us that x + 3 is also greater than 8. Therefore, when x is greater than 5, the expression |x + 3| represents the distance of x + 3 from zero, which is equal to x + 3 itself because x + 3 is positive.

As a result, we can simplify |x + 3| to x + 3 when x is greater than 5.

Deviance is a concept that refers to behaviors or actions that are outside of the norms and expectations of a particular society or group. In many ways, deviance clarifies moral boundaries and affirms norms because it helps define what is considered acceptable and unacceptable behavior within a particular community.

When individuals engage in deviant behavior, it draws attention to the fact that there are established norms and expectations for behavior within a society. For example, if someone steals from a store, it is considered deviant behavior because it goes against the norm of honesty and fair dealing. This deviant behavior highlights the fact that there is a norm of honesty and fair dealing in society, and helps to reinforce it. Similarly, when deviant behavior is punished, it sends a message to others in the community that the behavior is unacceptable and reinforces the norm against it. For example, if a person is punished for stealing from a store, it sends a message to others that this behavior is not tolerated and reinforces the norm of honesty and fair dealing.

In conclusion, deviance clarifies moral boundaries and affirms norms because it highlights and reinforces established expectations for behavior within a society. When individuals engage in deviant behavior, it brings attention to these norms and reinforces their importance.

Step-by-step explanation:

These values of h and k are specific to the given system of equations and may not apply to other systems.

(a) The system has no solution when h = 16.
(b) The system has a unique solution for any value of h ≠ 16.
(c) The system has many solutions when h = 16.

To determine the values of h and k that result in different solutions for the given system of equations, let's analyze the coefficient matrix of the system:
```
2   4
8   h
```
(a) To have no solution, the coefficient matrix must be inconsistent. This occurs when the determinant of the matrix is zero. In this case, the determinant is 2h - 32. So, to have no solution, we need 2h - 32 = 0. Solving this equation, we find h = 16. Therefore, the system has no solution when h = 16.

(b) To have a unique solution, the coefficient matrix must be consistent and have a non-zero determinant. This means that 2h - 32 ≠ 0. Since the determinant of the coefficient matrix is 2h - 32, we can conclude that the system has a unique solution for any value of h such that h ≠ 16.
(c) To have many solutions, the coefficient matrix must be consistent and have a determinant of zero. In this case, we need 2h - 32 = 0, which gives us h = 16. Therefore, the system has many solutions when h = 16.

Step-by-step explanation:

i multiplied the S values by the scale factor to get the S dash

The coordinates of the point S' after dilation is S' ( 4 , 2 )

Resizing an item uses a transition called Dilation. Dilation is used to enlarge or contract the items. The result of this transformation is an image with the same shape as the original. However, there is a variation in the shape's size. Dilation transformations ensure that the shape will stay the same and that corresponding angles will be congruent

Given data ,

Let the triangle be represented as ΔSTU

Now , the coordinates of the triangle are

S ( 2 , 1 ) , T ( 4 , 5 ) and U ( 4 , 1 )

Now , the dilation scale factor is k = 2

So , the coordinates of the triangle after the dilation is

The correct table which has zero slope is, Table 1.

The equation of line in point-slope form passing through the points

(x₁ , y₁) and (x₂, y₂) with slope m is defined as;

⇒ y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

Given that;

To find the correct table which has zero slope.

Now,

From 1;

Two points on the table are (-3, 2) and (-1, 2).

Hence,  Slope of the line is,

m = (y₂ - y₁) / (x₂ - x₁)

m = (2 - 2) / (- 1 + 3)

m = 0 / 2

m = 0

From 2;

Two points on the table are (-3, 3) and (-1, 1).

Hence,  Slope of the line is,

m = (y₂ - y₁) / (x₂ - x₁)

m = (1 - 3) / (- 1 + 3)

m = - 2 / 2

m = - 1

From 3;

Two points on the line are (1, 1) and (2, 2).

Hence,  Slope of the line is,

m = (y₂ - y₁) / (x₂ - x₁)

m = (2 - 1) / (2 - 1)

m = 1/1

m = 1

From 4;

Two points on the line are (-2, 1) and (-2, 2).

Hence,  Slope of the line is,

m = (y₂ - y₁) / (x₂ - x₁)

m = (2 - 1) / (- 2 + 2)

m = 1/0

m = ∞

Thus, Table 1 has slope zero.
