Find total surface area:

The correct option A, "None of the associations listed are correct," is the appropriate response.To determine the association suggested by the two-way table, we need to calculate the relative frequency of the data.

The table provides information about whether individuals have a brother and a sister.

Based on the options given, let's calculate the relative frequencies to see which association is suggested:

Calculate the relative frequency for individuals who have a brother and a sister:Relative frequency = (Number of individuals with both a brother and a sister) / (Total number of individuals)

Calculate the relative frequency for individuals who have a brother but no sister:Relative frequency = (Number of individuals with a brother but no sister) / (Total number of individuals)

Calculate the relative frequency for individuals who have a sister but no brother:Relative frequency = (Number of individuals with a sister but no brother) / (Total number of individuals)

Calculate the relative frequency for individuals who have neither a brother nor a sister:Relative frequency = (Number of individuals with neither a brother nor a sister) / (Total number of individuals)

By comparing the relative frequencies, we can determine which association is suggested by the data.Unfortunately, the given two-way table is missing, so we cannot perform the necessary calculations to determine the association.

From the  X coordinate is -0.45 centimeter and Y coordinate is -2.0 cm of the center of mass for the uniform plate.

According to the Question:

Since the plate is uniform, we can divide it into three rectangles, each with a mass proportional to its area and with its barycenter at its geometric center. We will refer to the large piece of 35cm x 10cm; it occupies 63.6% of the total surface and its barycenter is at

(x₁, y₁) = (−5.0cm,−2.5cm).

Now,

The top 20cm× 5cm piece has 18.2 % of the total area; its center of mass is at (x₂, y₂) = (10cm,12.5cm).  

Now,

The bottom 10cm× 10cm piece (section 3) also has 18.2 % of the total area; its center of mass is at (x₃, y₃)​ = (5cm,−15cm).

(a) The x coordinate of the center of mass for the plate is

   \(X_{com} = (0.636)X_1 + (0.182)X_2 + (0.182)X_3\)

            = -0.45 cm

(b) The y coordinate of the center of mass for the plate is

The solution to the system of equations is (7,1.5).Option (5,-2) is incorrect.

An equation is a mathematical statement that shows the equality between two expressions. It is written using an "equal to" sign ( = ) and involves one or more variables. Equations are used to describe relationships between unknown values, and can be used to model real-world problems and to solve them.

Addition/Elimination

We can solve this system of equations by addition/elimination. To do this, we will add the two equations together.

6x − 12y = 24
−x − 6y= 4

Adding these equations together gives us:

5x − 18y = 28

From this, we can solve for y:

y = 28/18
y = 1.5

We can then substitute this value of y into either of the original equations to solve for x:

6x − 12(1.5) = 24
6x = 24 + 18
6x = 42
x = 42/6
x = 7

Therefore, the solution to the system of equations is (7,1.5).

Step-by-step explanation:

The observation is located to the left of the mean by a distance of 1.2 standard deviations.

The z-score of an observation represents the number of standard deviations the observation is away from the mean.

If the z-score for a particular observation is z = -1.2, this means that the observation is 1.2 standard deviations below the mean.

If the mean is represented by μ and the standard deviation by σ, then we can express this observation as:

observation = μ + (z * σ)

observation = μ + (-1.2 * σ)

This means that the observation is located to the left of the mean by a distance of 1.2 standard deviations.

For example, The z-score represents the number of standard deviations an observation is above or below the mean of the distribution.

In this case, a z-score of -1.2 indicates that the observation is 1.2 standard deviations below the mean height of the group.

(a) Leg lengths: 6 and 6√2, Hypotenuse length: 6√2.

(b) Shorter leg length: 5, Longer leg length: 5√3, Hypotenuse length: 10.

To find the values of the triangle sides in special triangles, we can use the relationships within these triangles. There are two common special triangles: the 45-45-90 triangle and the 30-60-90 triangle.

45-45-90 triangle:

In a 45-45-90 triangle, the two legs are congruent, and the hypotenuse is the length of the leg times √2.

If the length of one leg is x, then the length of the other leg is also x, and the length of the hypotenuse is x√2.

30-60-90 triangle:

In a 30-60-90 triangle, the lengths of the sides are in a specific ratio.

If the shorter leg is x, then the longer leg is x√3, and the hypotenuse is 2x.

Now let's apply these relationships to find the values of the sides:

In a 45-45-90 triangle, if one leg has a length of 6, then the other leg also has a length of 6. The hypotenuse is found by multiplying the leg length by √2, which gives 6√2.

In a 30-60-90 triangle, if the shorter leg has a length of 5, then the longer leg is found by multiplying the shorter leg by √3, which gives 5√3. The hypotenuse is found by multiplying the shorter leg by 2, which gives 10.

Algebraically, we can write the solution set of the system of inequalities as follows:   -2x - 3 ≤ y ≤ 3x 2  and  y = -5 satisfies this inequality, the point (1, -5) is in the solution set of the system of inequalities

An algebraic expression is an expression made up of constant algebraic numbers, variables and  algebraic operations (addition, subtraction, multiplication, division and exponentiation, which is a rational number).

To determine the relationship between the point (1, -5) and the given system of inequalities, we must substitute the values ​​of x and y in each inequality and check whether the point satisfies the inequality or not. 

 For the first inequality, we have: 

 y ≤ 3 x 2 

 Substituting x = 1 and y = -5, we get: 

 -5 ≤ 3 (1) 2 

 -5 ≤ 5 

 This inequality is true, so the point (1, -5) satisfies this inequality.  

 For the second inequality, we have: 

 y ≥ -2x -3 

 Substituting x = 1 and y = -5, we get: 

 -5 ≥ -2(1) -3 

 -5 ≥ -5 

 This inequality is also true, so the point (1, -5) also satisfies this inequality. 

 Since the point (1, -5) satisfies both inequalities, it lies in the region that satisfies the system of inequalities. Geometrically, the point (1, -5) lies in the shaded area between the two lines y = 3x 2 and y = -2x -3 in the xy plane. Algebraically, we can write the solution set of the system of inequalities as follows: 

 -2x - 3 ≤ y ≤ 3x 2 

 Substituting x = 1, we get: 

 -2 (1) - 3 ≤ y ≤ 3 (1) 2 

 -5 ≤ y ≤ 5 

 Since y = -5 satisfies this inequality, the point (1, -5) is in the solution set of the system of inequalities

Answer:

Step-by-step explanation:

Let's temporarily replace the inequality sign ">" with "=".

This gives us: 5x - 2 = 3x + 11.

If we subtract 3x from both sides we are left with:

2x - 2 = 11.

If we add 2 to both sides, we are left with:

2x = 13.

If we divide both sides by 2, we are left with

x = 6.5.

Answer;

In binary representation, each bit can be either 0 or 1. Using five binary bits, we can obtain 32 different numbers. Therefore, the correct answer is (B).

With five binary bits, we have five positions, and each position can have two possibilities (0 or 1). To calculate the total number of different numbers we can obtain, we need to raise 2 to the power of the number of bits. In this case, we have \(2^5,\) which equals 32. Therefore, we can obtain 32 different numbers using five binary bits. To understand this concept, we can think of each binary bit as a switch that can be either on (1) or off (0). With five switches, we have a total of 32 different combinations or numbers that can be represented. These numbers range from 0 (all switches off) to 31 (all switches on). Therefore, the correct answer is (B), which states that we can obtain 32 different numbers using five binary bits.
