Answer: 2w = 16

Step-by-step explanation:

From the question, we are informed that Luis walked for 16 minutes while Natalie walked for w minutes and that Luis walked twice as long as Natalie.

The number of minutes that Natalie walk will be:

2 × w = 16

2w = 16

Solving further will be:

2w = 16

w = 16/2

w = 8

Natalie walked for 8 minutes

Answer:

8 minutes

Step-by-step explanation:

First, you need to divide 16 by 2 which it is 8.

Answer:

232°

Step-by-step explanation:

1. 180-52=128

2. 360-128=232

first you subtract 52 from 180 bc you have to get the angle not included for calculating the whole bearing bc the starting point is the north line. so everything before the north line is not valid bc when you're calculating an angle like this you go from lef to to right, clockwise. in every calculation of bearings you go clockwise. next you just subtract the product you got from 360 and that's it.

hope it didn't sound too complicated.

Answer:

To solve this problem, we need to use the central limit theorem, which states that the distribution of the sample means approaches a normal distribution as the sample size increases, regardless of the shape of the population distribution.

Given that the sample size is n = 69, the mean diameter of the population is μ = 209 inches, and the standard deviation of the population is σ = 2.4 inches.

We need to find the probability that the mean diameter of the sample shafts would be less than 209.1 inches, which can be written as:

P(X < 209.1)

To solve this problem, we need to use the central limit theorem, which states that the distribution of the sample means approaches a normal distribution as the sample size increases, regardless of the shape of the population distribution.

Given that the sample size is n = 69, the mean diameter of the population is μ = 209 inches, and the standard deviation of the population is σ = 2.4 inches.

We need to find the probability that the mean diameter of the sample shafts would be less than 209.1 inches, which can be written as:

P(X < 209.1)

To standardize this value, we need to calculate the z-score as follows:

z = (X - μ) / (σ / sqrt(n))

z = (209.1 - 209) / (2.4 / sqrt(69))

z = 0.4639

We can now find the probability using the standard normal distribution table or a calculator:

P(Z < 0.4639) = 0.6779

Therefore, the probability that the mean diameter of the sample shafts would be less than 209.1 inches is approximately 0.6779, rounded to four decimal places.

In this case, the population mean is 209 inches, and the sample mean we're interested in is 209.1 inches. So the z-score would be:
z = (209.1 - 209) / 0.2898 = 0.3456
Therefore, the probability that the mean diameter of the sample shafts would be less than 209.1 inches is 0.6368, rounded to four decimal places.

To answer your question, we will use the Central Limit Theorem and the z-score formula. Here are the steps:

we can use the formula for the z-score of the sample mean, which is:
z = (sample mean - population mean) / standard error

1. Find the mean (μ) and standard deviation (σ) of the population.
  μ = 209 inches
  σ = 2.4 inches

2. Determine the sample size (n) and the mean diameter you want to calculate the probability for (x).
  n = 69
  x = 209.1 inches

3. Calculate the standard error (SE) of the sample mean using the formula: SE = σ / √n
  SE = 2.4 / √69 ≈ 0.2892

4. Calculate the z-score using the formula: z = (x- μ) / SE
  z = (209.1 - 209) / 0.2892 ≈ 0.3455

5. Find the probability that the mean diameter of the sample shafts would be less than 209.1 inches by looking up the z-score in a z-table or using a calculator that can compute normal probabilities.
  P(Z < 0.3455) ≈ 0.635

The probability that the mean diameter of the sample shafts would be less than 209.1 inches is approximately 0.6350 or 63.50%.

The resulting curve is a limaçon (a type of cardioid) with a loop. It is centered at the origin and has an inner loop with a radius of 4/5 and an outer loop with a radius of 8/5. The curve has symmetry about both the x-axis and the y-axis. Option C is Correct.

To convert the equation R = -8 cos(θ) + 4 sin(θ) to Cartesian coordinates, we can use the following equations:

x = R cos(θ)

y = R sin(θ)

Substituting the given equation, we get:

x = (-8 cos(θ) + 4 sin(θ)) cos(θ)

y = (-8 cos(θ) + 4 sin(θ)) sin(θ)

Simplifying these equations, we get:

x =\(-8 cos^2\)(θ) + 4 cos(θ) sin(θ)

y = -8 cos(θ) sin(θ) +  \(4 sin^2\)(θ)

For a larger input size of 320,000 elements, it will take 240 ms to sort each half and 24 ms to merge the sorted halves, resulting in a total time of 264 ms.

The given information describes the time required for sorting and merging operations on two different input sizes. For 80,000 elements, it takes 18 ms to sort each half, resulting in a total of 36 ms for sorting. Merging the two sorted halves with 80,000 numbers in each takes 40 - 18 = 22 ms.

When the input size is doubled to 320,000 elements, the sorting time for each half increases to 240 ms, as it scales linearly with the input size. The merging time, however, remains constant at 4 ms since the size of the sorted halves being merged is the same.

Thus, the total time for sorting and merging 320,000 elements is the sum of the sorting time (240 ms) and the merging time (4 ms), resulting in a total of 264 ms.

Therefore, based on the given information, the total time required for sorting and merging 320,000 elements is 264 ms.

The distance between Kentucky Avenue between E. Capitol Street and Independence Avenue is 5760 feet (to the nearest foot).

To the nearest foot, To find the distance between two points, we use the distance formula, which is as follows: d = \(sqrt[(x2 - x1)^2 + (y2 - y1)^2] \\\)

Let's assume the coordinates of these two points. The coordinates of the first point (E. Capitol Street, Kentucky Avenue) are (x1, y1) = (0, 0). The coordinates of the second point (Independence Avenue, Kentucky Avenue) are (x2, y2) = (2400, 0).The distance between these two points can be calculated by using the distance formula as follows:

\(d = sqrt[(x2 - x1)^2 + (y2 - y1)^2]\)

\(d = sqrt[(2400 - 0)^2 + (0 - 0)^2]\)

\(d = sqrt[2400^2]\)

The area bounded by the curves y² - 3x + 3 and x = 4 can be determined using Simpson's rule.

Simpson's rule is a numerical method used to approximate the definite integral of a function over a given interval. It divides the interval into smaller subintervals and approximates the integral by fitting parabolic curves to these subintervals. The area under the curve is then estimated by summing up the areas of these parabolic curves.

In this case, the first step is to find the points of intersection between the curves y² - 3x + 3 and x = 4. By setting y² - 3x + 3 equal to x = 4, we can solve for the values of y. Once we have the points of intersection, we can use Simpson's rule to approximate the area between the curves. Simpson's rule involves dividing the interval between the points of intersection into an even number of subintervals and using a specific formula to calculate the area for each subinterval. Finally, we sum up the areas of these subintervals to obtain an approximation of the total area bounded by the curves.

By following this process, we can use Simpson's rule to estimate the area bounded by the curves y² - 3x + 3 and x = 4.

The model that is more appropriate for modelling the data would be an exponential model.

An exponential function aptly captures the dynamics of a changing dependent variable (in this scenario, the car's value) at an accelerating or decelerating pace over time. As the years accumulate, the car's value experiences a decrement, showcasing a trend that aligns harmoniously with the principles of exponential decay.

Conversely, a linear function assumes a fixed rate of change, which might not adequately represent the descending trajectory of the car's value across time. Linear functions imply a consistent devaluation year by year, whereas the available information suggests a gradual diminishing of the rate of decrease.

Step-by-step explanation:

Magnitude = sqrt ( (-12)^2 + (-4)^2 ) = sqrt 160 = 12.649

Angle = arctan(-4/-12) = 198 degrees

The Magnitude: 12.649 and Direction: 18° (option c).

To find the magnitude and direction of the vector v = (-12, -4), we can use the following formulas:

Magnitude (or magnitude) of v = |v| = √(vₓ² + \(v_y\)²)

Direction (or angle) of v = θ = arctan(\(v_y\) / vₓ)

where vₓ is the x-component of the vector and \(v_y\) is the y-component of the vector.

Let's calculate:

Magnitude of v = √((-12)² + (-4)²) = √(144 + 16) = √160 ≈ 12.649 (rounded to the thousandths place)

Direction of v = arctan((-4) / (-12)) = arctan(1/3) ≈ 18.435°

Since we need to round the direction to the nearest degree, the direction is approximately 18°.

So, the correct answer is:

Magnitude: 12.649 (rounded to the thousandths place)

Direction: 18° (rounded to the nearest degree)
