Answer:

30 is 120% of 25

Step-by-step explanation:

30 = 120% of y

\(\frac{120}{100}\) × y = 30

After multiplying both sides by 100 and dividing both sides by 120, we have

y = 30 × \(\frac{100}{120}\)

y = 25

On average, the boy of age 8 would be taller than the girl of age 8, and similarly, the boy of age 10 would be taller than the girl of age 10.

Generally, boys tend to experience a growth spurt during puberty, resulting in a significant increase in height compared to girls of the same age. At the age of 8, boys are typically taller than girls due to factors such as genetics, hormonal differences, and skeletal development. During this age, boys may already be starting their growth spurt, while girls may not have entered theirs yet. Therefore, it is more likely that the boy of age 8 would be taller than the girl of age 8.

Similarly, at the age of 10, boys usually continue their growth spurt and experience further height gains. Girls, on the other hand, may begin their growth spurt around this age or shortly after. As a result, the boy of age 10 would generally be taller than the girl of age 10 due to the ongoing differences in growth patterns between boys and girls during this stage of development. It's important to note that these are general trends, and individual variations in growth rates and genetics can lead to exceptions.

Answer:

6 3/8 pounds (also 6.375 pounds)

Step-by-step explanation:

2 2/3 + 1 5/6 + 1 7/8 = x

8/3 + 11/6 + 15/8 = x

(multiply each fraction by to create the denominator 24)

8/3 x 8/8 = 64/24

11/6 x 4/4 = 44/24

15/8 x 3/3 = 45/24

64/24 + 44/24 = 108/24

108/24 + 45/24 = 153/24

153/24 = 6.375 = 6 3/8

Step-by-step explanation:

(a) The cumulative distribution function F(x) for the waiting time is\(F(x) = 1 - e^(-0.1x).\)

(b) The probability that a customer waits more than 20 minutes is approximately 0.135.

(c) The probability that a customer waits less than 4 minutes is approximately 0.332.

(a) To find the cumulative distribution function (CDF) F(x), we integrate the probability density function (PDF) f(x) from negative infinity to x. In this case, the PDF is given as \(f(x) = 0.1e^x\). Integrating f(x) with respect to x gives us\(F(x) = ∫(0.1e^x) dx.\) Evaluating this integral, we have \(F(x) = -0.1e^(-x) + C.\) Since F(x) is a cumulative probability, it approaches 1 as x approaches infinity. Therefore, we set the constant C to 1 to get the final CDF as \(F(x) = 1 - e^(-0.1x)\).

(b) To find the probability that a customer waits more than 20 minutes, we need to evaluate\(1 - F(x) for x = 20.\) Plugging in the value, we have \(P(X > 20) = 1 - F(20) = 1 - (1 - e^(-0.1*20)) = e^(-2) ≈ 0.135.\) Therefore, the probability that a customer waits more than 20 minutes is approximately 0.135.

(c) To find the probability that a customer waits less than 4 minutes, we need to evaluate F(x) for x = 4. Plugging in the value, we have\(P(X < 4) = F(4) = 1 - e^(-0.1*4) ≈ 0.332.\)Therefore, the probability that a customer waits less than 4 minutes is approximately 0.332.

The probability density function (PDF) represents the likelihood of a random variable taking on a specific value or falling within a particular range. The cumulative distribution function (CDF), on the other hand, gives the probability that the random variable is less than or equal to a certain value. By integrating the PDF, we can obtain the CDF, which allows us to calculate probabilities for different scenarios, such as waiting times in this case.

The elevation gain of Mount Everest is 15,028 feet, a very impressive feat considering it is the highest elevation gain of any mountain in the world.

The difference between the height at the base of Mount Everest, which is 14,000 feet and the summit, which is 29,028 feet is 15,028 feet. This is also known as the elevation gain. It can be calculated using the following formula:

Elevation Gain = Summit Height - Base Height

So in this case, Elevation Gain = 29,028 ft - 14,000 ft

Which gives us: Elevation Gain = 15,028 ft

The elevation gain of Mount Everest is 15,028 feet, a very impressive feat considering it is the highest elevation gain of any mountain in the world. It is also the highest mountain in the world, with the summit standing at an impressive 29,028 feet. This is a testament to the power of nature and the sheer scale of Mount Everest.

The maximum dimensions  6 Centimeters for the side length and 12 centimeters for the height.For square base dimensional is 7 and hexagonal base dimension is 6

1. Square Base:

Let's assume the side length of the square base is x centimeters. Since the height is double the side length, the height of the pyramid will be 2x centimeters.

The surface area of the four triangular sides of the pyramid is given by:

Surface Area of Triangular Sides = 4 * (1/2 * x * 2x) = 4x^2

The surface area of the square base is given by:

Surface Area of Square Base = x^2

To find the maximum dimensions, we need to maximize the surface area while keeping it under 250 square centimeters. Therefore, we have the equation:

Surface Area of Triangular Sides + Surface Area of Square Base ≤ 250

4x^2 + x^2 ≤ 250

5x^2 ≤ 250

x^2 ≤ 50

x ≤ √50

Rounding √50 to the nearest whole number, we get x ≈ 7. So, the maximum side length for the square base is approximately 7 centimeters. The height will be double the side length, so the maximum height will be approximately 14 centimeters.

2. Hexagonal Base:

Let's assume the side length of the hexagonal base is y centimeters. Again, the height of the pyramid will be 2y centimeters.

The surface area of the six triangular sides of the pyramid is given by:

Surface Area of Triangular Sides = 6 * (1/2 * y * 2y) = 6y^2

The surface area of the hexagonal base is given by:

Surface Area of Hexagonal Base = (3√3 / 2) * y^2

To find the maximum dimensions, we have the equation:

Surface Area of Triangular Sides + Surface Area of Hexagonal Base ≤ 250

6y^2 + (3√3 / 2) * y^2 ≤ 250

Simplifying and solving the inequality, we find that y ≤ √(250 / (6 + 3√3 / 2)). Rounding this value to the nearest whole number, we get y ≈ 6.

So, the maximum side length for the hexagonal base is approximately 6 centimeters.

The height will be double the side length, so the maximum height will be approximately 12 centimeters.

For a square base, the maximum dimensions are approximately 7 centimeters for the side length and 14 centimeters for the height.

For a hexagonal base, the maximum dimensions are approximately 6 centimeters for the side length and 12 centimeters for the height.

As for Tiva's babysitting earnings, if she continues to babysit for 6 hours, she will earn $48, and if she babysits for 8 hours, she will earn $64.

To adjust the number of flowers for different-sized decorations based on the instructions, we need to consider the desired size relative to the medium-sized decoration. Let's complete the statements accordingly:

For a small-sized decoration, Pete should use flowers.

To adjust for a small-sized decoration, we can use fewer flowers compared to the medium-sized decoration. The specific number of flowers is not mentioned in the instructions, so we cannot provide a precise answer. However, we can suggest using a smaller proportion of flowers, such as 6 or 7 flowers, to create a smaller arrangement.

For a large-sized decoration, Pete should use flowers.

To adjust for a large-sized decoration, we can use more flowers compared to the medium-sized decoration. Again, the specific number of flowers is not provided in the instructions, so we can propose using a larger proportion of flowers, such as 12 or 15 flowers, to create a larger arrangement.

Regarding Tiva's babysitting earnings, we can complete the statements as follows:

If Tiva continues to babysit for 6 hours, she will earn dollars.

Since Tiva earns $48 for 6 hours of babysitting, we can calculate her earnings per hour by dividing the total earnings by the number of hours: $48 / 6 = $8. Therefore, if she continues to babysit for 6 hours, she will earn $8 per hour, resulting in a total of $48.

If Tiva babysits for 8 hours, she will earn dollars.

To determine Tiva's earnings for 8 hours of babysitting, we can multiply her earnings per hour ($8) by the number of hours: $8 * 8 = $64. Therefore, if Tiva babysits for 8 hours, she will earn $64.

In summary, to adjust the number of flowers for different-sized decorations, we can use a smaller proportion of flowers for a small-sized decoration and a larger proportion of flowers for a large-sized decoration.
