The distribution of weights of adult dogs is strongly skewed right, with a mean of 15 pounds and a standard deviation of 4 pounds.

A right-skewed distribution means that the tail of the distribution extends towards larger values, indicating a larger number of lighter dogs and fewer heavier dogs. In this case, the mean weight of adult dogs is 15 pounds, indicating the central tendency of the distribution.

The standard deviation of 4 pounds measures the variability or spread of the weights around the mean. A larger standard deviation suggests a wider range of weights in the distribution.

Understanding the shape, mean, and standard deviation of the weight distribution provides valuable information about the characteristics of the breed.

The number of gold chains that Geraldo will have is 16 gold chains.

A fraction is simply a piece of a whole. The number is represented mathematically as a quotient where the numerator and denominator are split. In a simple fraction, the numerator as well as the denominator are both integers.

Since Geraldo has a gold chain that is 34 inches long and he cuts it into 2 1/8 - inch-long chains.

The number of chains will be:

= 34 ÷ 2 1/8

= 34 / 2.125

= 16

He'll have 16 chains.

Step-by-step explanation:

Since the distance from a point to point C is 1 and the distance from that same point to point B is 4, the point must be: C. point D.

In Mathematics and Geometry, a number line simply refers to a type of graph with a graduated straight line which comprises both positive and negative numbers that are placed at equal intervals along its length.

This ultimately implies that, a number line primarily increases in numerical value towards the right from zero (0) and decreases in numerical value towards the left from zero (0).

From the number line shown above, we have:

Distance = 4 + (-1)

Distance = 4 - 1

Distance = 3 (point D).

Total (2008) = 18,237

2008 -18 percent change (10 years ) = 40%

So, for each year:

40%/10 = 4%

Multiply the percentage in decimal form by the total number of workers in 2008.

18,237 x (4/100) = 729.45 workers per year

Step-by-step explanation:

There are over 22 billion possible license plates with the given restrictions.

To find the number of different license plates possible in 2020 with the given restrictions, we need to use the principle of multiplication.

There are a total of 26 letters in the English alphabet, but we cannot use the letters d, t, or x in the fourth position, or the letters i, o, or q in any position.

For the first three positions, we have 26 options for each position, since we can use any letter. Therefore, the number of possible combinations for the first three positions is 26 x 26 x 26 = 17,576.

For the fourth position, we cannot use the letters d, t, or x, so we have 23 options.

For the fifth position, we have 26 options again, since we can use any letter.

For the sixth position, we cannot use the letters i, o, or q, so we have 23 options.

Therefore, the total number of possible license plates is:

17,576 x 23 x 26 x 23 = 22,075,269,568

So, there are over 22 billion possible license plates with the given restrictions.

Answer: 60 inches in 5 feet

Step-by-step explanation:

a) To obtain the potential pressure drop in the wellbore, we can use the hydrostatic pressure equation.

The potential pressure drop is equal to the pressure gradient multiplied by the length of the wellbore. The pressure gradient can be calculated using the equation: Pressure gradient = (density of oil × acceleration due to gravity) × sin(θ), where θ is the deviation angle of the wellbore from horizontal flow. In this case, the pressure gradient would be (48 lbm/ft^3 × 32.2 ft/s^2) × sin(15°). Multiplying the pressure gradient by the wellbore length of 6,000 ft gives the potential pressure drop.

b) To determine the frictional pressure drop in the wellbore, we can use the Darcy-Weisbach equation. The Darcy-Weisbach equation states that the pressure drop is equal to the friction factor multiplied by the pipe length, density, squared velocity, and divided by the pipe diameter. However, to calculate the friction factor, we need the Reynolds number. The Reynolds number can be calculated as (density × velocity × diameter) divided by the oil viscosity. Once the Reynolds number is known, the friction factor can be determined. Finally, using the friction factor, we can calculate the frictional pressure drop.

c) To calculate the in-situ oil velocity, we need to consider the total volume of the pipe, including both oil and gas. The total pipe volume is calculated as the pipe cross-sectional area multiplied by the wellbore length. Subtracting the gas volume from the total volume gives the oil volume. Dividing the oil volume by the total time taken by the oil to flow through the pipe (converted to seconds) gives the average oil velocity.

d) The flow regime of the two-phase flow can be determined based on the oil and gas mixture properties and flow conditions. Common flow regimes include bubble flow, slug flow, annular flow, and mist flow. These regimes are characterized by different distribution and interaction of the oil and gas phases. To determine the specific flow regime, various parameters such as gas and liquid velocities, mixture density, viscosity, and surface tension need to be considered. Additional information would be required to accurately determine the flow regime in this scenario.

Answer:

-3.99

Step-by-step explanation:

Answer: \(y=x-2\)

Step-by-step explanation:

First, we need to find the slope.

\(m=\frac{Y2-Y1}{X2-X1}\)

\(m=\frac{1-2}{3-4}\)

\(m=\frac{1}{1}\)

\(m=1\\\)

Next, we can use the point-slope form to find the equation:

\(Y-Y1=m(X-X1)\)

\(Y-2=1(X-4)\)

\(y-2=x-4\)

\(y=x-2\)

Answer: V = 28,600(0.909)^2

Step-by-step explanation: This is because the value of the car depreciates at a rate of 9.1% per year, which means that the value after the first year will be 0.909 times the original value, and the value after the second year will be 0.909 times the value after the first year. Therefore, we need to multiply the original value of the car by (0.909)^2 to find the value after 2 years.

Given problem, To find:1. The number of positive three-digit integers that are multiples of 7.2. The probability that a randomly chosen positive three-digit integer is a multiple of 7.

Solution:1. To find the number of positive three-digit integers that are multiples of 7:We need to find the largest 3-digit multiple of 7 and the smallest 3-digit multiple of 7. Largest 3-digit multiple of 7 is 994 and the smallest 3-digit multiple of 7 is 105.  Multiples of 7 can be obtained by adding 7 to the previous number.

Largest 3-digit multiple of 7 = 994. Smallest 3-digit multiple of 7 = 105. Let's subtract both the above numbers to get the total number of positive three-digit integers that are multiples of 7.994 - 105 = 889.

Hence, there are 889 positive three-digit integers that are multiples of 7.2. To find the probability that a randomly chosen positive three-digit integer is a multiple of 7: Total number of three-digit integers = 999 - 100 + 1 = 900. Number of positive three-digit integers that are multiples of 7 = 889. We need to find the probability that a randomly chosen positive three-digit integer is a multiple of 7. P(positive three-digit integer is a multiple of 7) = number of positive three-digit integers that are multiples of 7/ total number of three-digit integers⇒ P(positive three-digit integer is a multiple of 7) = 889/900⇒ P(positive three-digit integer is a multiple of 7) = 0.987. Hence, the probability that a randomly chosen positive three-digit integer is a multiple of 7 is 0.987.
