The probability is a + b + c = -382

Probability refers to potential. A random event's occurrence is the subject of this area of mathematics. The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.

Every cube's side is [tex]\sqrt[3]{1000}[/tex] = 10

Since there are 512 unpainted cubes within, the likelihood is 1⁵¹² = 1

There are 8 corners, and each one has a chance of 3 / 6 = 1 / 2 = 2⁻¹ so the probability is 1⁸ / 2 = 1 / 2⁸

There are 8 * 12 = 96 edge pieces (12 edges total, with 8 on each edge; each cube has a probability of 4 / 6 = 2 / 3, so the probability is 2⁹⁶ / 3 = 2⁹⁶ / 3⁹⁶

There are 8 * 8 * 6 = 384 center cubes, each having a chance of 5 / 6, so the probability is 5³⁸⁴ / 6 = 5³⁸⁴ / 6³⁸⁴ = 5³⁸⁴ / (2³⁸⁴ * 3³⁸⁴)

So, the probability is:

(1 / 2⁸) * (2⁹⁶ / 3⁹⁶) * [5³⁸⁴ / (2³⁸⁴ * 3³⁸⁴)]

= (5³⁸⁴ * 2⁹⁶) / (2³⁹² * 3⁴⁷⁰)

= 5³⁹⁴ * 2⁹⁶ * 2⁻³⁹² * 3⁻⁴⁷⁰

= 5³⁸⁴ * 2⁻²⁹⁶ * 3⁻⁴⁷⁰

Thus, a + b + c = -382

The definition for the function is y = {-2x +1   x < 1 ; -x + 2   x ≥ 1. The correct option is b.

From the question, we are to determine the equation for the function

First, we will determine the equation for when x < 1

Picking the points (-1, 3) and (0, 1)

Using the formula,

(y - y₁) / (x - x₁) = (y₂ - y₁) / (x₂ - x₁)

(y - 3) / (x - -1) = (1 - 3) / (0 - -1)

(y - 3) / (x + 1) = -2 / (0 + 1)

(y - 3) / (x + 1) = -2 / 1

(y - 3) / (x + 1) = -2

y - 3 = -2(x + 1)

y - 3 = -2x - 2

y = -2x - 2 + 3

y = -2x + 1

Thus,

When x < 1, the function is y = -2x + 1

Now, determine the equation for when x ≥ 1

Picking the points (1, 1) and (2, 0)

(y - y₁) / (x - x₁) = (y₂ - y₁) / (x₂ - x₁)

(y - 1) / (x - 1) = (0 - 1) / (2 - 1)

(y - 1) / (x - 1) = -1 / 1

(y - 1) / (x - 1) = -1

y - 1 = -1(x - 1)

y - 1 = -x + 1

y = -x + 1 + 1

y = -x + 2

Thus,

When x ≥ 1, the function is y = -x + 2

A mathematical equation uses variables, numbers, and constants to show that two values are equal.

Mathematical equations connect two mathematical expressions using the equal sign (=).

Let the original number = x

According to the statement:

2x + 28 = {4}{9}

This implies that:

2x + 28 = 36

Subtracting 28 from both sides gives:

2x = 8

The range thumb rule The minimum and maximum values for the usual value, which is two, are 812.14 and 885.85, respectively.

An efficient way to calculate the range from the standard deviation is to use the range rule of thumb. The range is normally around four times the standard deviation, according to this information. Inferring that your range is around eight if your standard deviation is 2, for example.

As an illustration of a binomial distribution, we'll utilize seeds.

According to given data;

Let "X" represent the number of tomato seeds that actually germinate based on the data provided.

With the knowledge provided above, we can now determine the:

The median number of seeds that we may anticipate to germinate

standard deviation (σ): sqrt of n*p*(1-p)

Once you calculate the mean and standard deviation, you can calculate the minimum usual value and the max usual value.

Now, in your problem:

n = 1415

p = 3/5

so,

the mean would be: (1415)(3/5) = 849

the standard deviation would be:  sqrt (mean)(1-3/5) = 18.4282

Next, we find the minimum and maximum usual values according to the equations you gave:

minimum:  mean - 2(standard deviation)

                = 849 - 2(18.4282)

                = 812.1436

maximum: mean + 2(standard deviation)

                = 849 + 2(18.4282)

                = 885.8564

Using the exterior angle of a polygon theorem, the value of the missing angle is 58°

From the question, we are to calculate the value of the missing angle.

From the given information, the missing angle is (3x -2)°.

To calculate the value of the missing angle,

First, we will determine the value of x

From the Exterior angle of a polygon theorem, we can write that

90° + (3x + 12)° + (4x - 10)° + (3x - 2)° + 70° = 360°

(3x + 12)° + (4x - 10)° + (3x - 2)° = 360° - 70° - 90°

3x° + 12° + 4x° - 10° + 3x° - 2° = 200°

10x° = 200° + 2° + 10° - 12°

10x° = 200°

x = 200/10

x = 20

The missing angle is (3x -2)°

Substitute the value of x

(3(20) -2)°

= (60 -2)°

= 58°

Answer:

72,000 yards

Step-by-step explanation:

The scale factor can be found by doing:

[tex]240 \div 4 = 60[/tex]

This means that 60 is the scale factor. You can apply the scale factor to the length of the rectangular building, meaning that the length of the actual building is:

[tex]5 \cdot 60 = 300[/tex] yards

So, if the building is 240 yards wide, and 300 yards long. You can find the area of the actual building just like any other rectangle using:

[tex]A = l \cdot w[/tex]

(Area = length * width)

So, the final answer is:

[tex]A = 300 \cdot 240\\ A= 72,000[/tex]

This means that the area of the actual building is 72,000 yards.

The value of x if R is the midpoint of QS is 31 units.

The midpoint is the middle point of a line segment.

It is equidistant from both endpoints, and it is the centroid both of the segment and of the endpoints.

The midpoint is halfway between the two end points.

Therefore, R is the midpoint of QS

Hence,

QS = QR + RS

QR = 5x - 15

QS = 100

Therefore, QR and RS are congruent because R is the midpoint of QS

QR = RS

Hence,

100 = 5x - 15 + 5x - 15

100 = 10x - 30

100 + 30 = 10x

130 = 10x

Step-by-step explanation:

Imagine flipping a coin. There is a 50% likelihood that you would get tails. However, it doesn't happen all the time. If you flipped it just a few times, you could get all tails and have 100% tails.

However, if you experimented a lot of times (a large number), you almost certainly wouldn't get all tails. You would get close to 50%. That is the main point of the law.

Applying the rules of exponents, the value of n in the equation given is calculated as: n = 8.

The product rule of exponents says that when the base are the same, add their exponents together.

For example, m × m² = m^(1 + 2) = m³.

The exponents are 1 and 2. The expression has similar base of m. Therefore, to multiply m and m² together, we would simply add their exponents together while the final result will be the same base.

Also, the negative rule of exponents states that we subtract their exponents if they have he same base.

For example:

m³/m² = m³ ÷ m² = m^(3 - 2) = m.

Given the equation:

[tex]\frac{4^3 \times 8^2}{2^n} = 2^4[/tex]

Simplify the bases to make all equal

= [tex]\frac{2^{(2)(3)} \times 2^{(3)(2)}}{2^n} = 2^4[/tex]

= [tex]\frac{2^{6} \times 2^{6}}{2^n} = 2^4[/tex]

Apply the product rule and the negative rule of exponents to find the value of n in tye equation:

[tex]2^{(6 + 6 - n)} = 2^4\\\\2^{(12 - n)} = 2^4\\\\[/tex]

The bases will cancel each other:

12 - n = 4

Subtract 12 from both sides

12 - n - 12 = 4 - 12

-n = -8
