Find the midpoint of points (-4,3) and (4,-3)

The values for the parabola are found as-

For the given question.

The total horizontal distance covered by water is 10 feet.

The maximum height attained by nozzle of water is 8 feet.

Thus, the vertex of parabola (h, k) = (5, 8)

The nozzle was 4 foot above the ground, a = 4.

The equation of parabola becomes;

y = a(x - h)² + k

y = 4(x - 5)² + 8

Thus, the equation of parabola becomes; y = 4(x - 5)² + 8.

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 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 perimeter and area of each of the composite figure is:

a. Area: 138.6 mm²; Perimeter = 50.27 mm.

b. Area: 120.5 cm²; Perimeter = 42.7 cm

c. Area: 521.1 mm²; Perimeter: 95.8 mm

Area of a circle = πr²

Area of a triangle = 1/2(base)(height).

Area of a rectangle = (length)(width).

The perimeter of a composite figure = the sum of all lengths of the sides surrounding the composite figure.

a. The area of the composite figure = area of rectangle + area of two semicircles

Two semicircles = 1 circle

Area of the rectangle = (15)(5) = 75 mm²

Area of the two semicircles = πr² = π(4.5²) = 63.6 mm²

The area of the composite figure = 75 + 63.6 = 138.6 mm².

Perimeter = 5(2) + 4(3) + (perimeter of 1 circle)

Perimeter = 5(2) + 4(3) + (2πr)

Perimeter = 5(2) + 4(3) + (2π(4.5))

Perimeter = 50.27 mm.

b. Area = area of triangle + area of square + area of half circle

Area = 1/2(base)(height) + s² + 1/2(πr²)

Base = 5 cm

Height = 7 cm

s = √(7² + 5²) = 8.6 cm [Pythagorean theorem]

r = 8.6/2 = 4.3 cm

Area = 1/2(5)(7) + 8.6² + 1/2(π(4.3²))

Area = 120.5 cm²

Perimeter = 5 + 7 + 8.6 + 8.6 + (perimeter of half circle)

Perimeter = 5 + 7 + 8.6 + 8.6 + 1/2(2πr)

Perimeter = 5 + 7 + 8.6 + 8.6 + (2π(4.3))

Perimeter = 42.7 cm

c. Area = area of triangle + area of rectangle + area of half circle

Area = 1/2(base)(height) + (length)(width) + 1/2(πr²)

Base = 32 - 20 = 12 mm

Height = 14 mm

Length = 20 mm

Width = 14 mm

r = 1/2(20) = 10 mm

Area = 1/2(12)(14) + (20)(14) + 1/2(π(10²))

Area = 521.1 mm²

Perimeter = 14 + 32 + hypotenuse of the triangle + (perimeter of half circle)

Hypotenuse = √(12² + 14²) = 18.4 mm

Perimeter of half circle = 1/2(2πr) = 1/2(2π(10)) = 31.4

Perimeter of the composite figure = 14 + 32 + 18.4 + 31.4

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)

Answer: The correct answer is the Law of Large Numbers

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.

The more trials you do, the more likely you will get close to the theoretical value.

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

Divide both sides by -1

n = 8

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
