-36/24 expressed as a rational number with the numerator first 9 second 6 is 1 1/2.

To express -36/24 as a rational number with the numerator first 9 second 6, we need to divide the numerator by the denominator and then rearrange the terms accordingly.

First, let's divide the numerator -36 by the denominator 24:

-36 ÷ 24 = -1.5

Now, let's express -1.5 as a rational number with the numerator first 9 second 6.

We can do this by expressing -1.5 as a mixed number.

To convert -1.5 to a mixed number, we take the absolute value of -1.5, which is 1.5.

Then, we divide 1.5 by 1 to get the whole number part and the decimal part:

1.5 ÷ 1 = 1 remainder 0.5

The whole number part is 1, and the decimal part is 0.5.

Now, let's express this mixed number as a rational number with the numerator first 9 second 6:

1 0.5

To convert the decimal part 0.5 to a fraction, we note that 0.5 is equal to 1/2.

-36/24 as a rational number with the numerator first 9 second 6 is:

The measure of side EF in triangle DEF is 5.34 units when angle D measures 40° and its adjacent side measures 7.6 units.

To get this answer, use the Pythagorean Theorem:

a2 + b2 = c2,

where a and b are the lengths of the sides adjacent to the right angle, and c is the length of the hypotenuse.

In this case, a = 7.6 and b = 5.34, so c = 8.93. Round this to the nearest hundredth and you get 5.34.

The Pythagorean Theorem states that in a right triangle, the sum of the squares of the two sides adjacent to the right angle is equal to the square of the hypotenuse.

The summation of the series ¹³∑ₙ₎ ₁ (3n - 1) is 260.

Given the summation in the question;

¹³∑ₙ₎ ₁ (3n - 1)

First, we split the summation into smaller summations that fits the summation rule.

¹³∑ₙ₎ ₁ (3n - 1) = 3 ¹³∑ₙ₎ ₁ (n) + ¹³∑ₙ₎ ₁ (- 1)

Now, lets evaluate 3 ¹³∑ₙ₎ ₁ (n).

Using the formula for the summation of a polynomial with degree 1

ⁿ∑ₐ₎ ₁ (a) = n( n + 1 ) / 2

Plug in the values

3 ¹³∑ₙ₎ ₁ (n) = (3) (( 13(13+1))/2)

3 ¹³∑ₙ₎ ₁ (n) = (3) (( 13(14))/2)

3 ¹³∑ₙ₎ ₁ (n) = (3) (182/2)

3 ¹³∑ₙ₎ ₁ (n) = (3) (91)

3 ¹³∑ₙ₎ ₁ (n) = 273

Next, evaluate ¹³∑ₙ₎ ₁ (- 1)

Using the formula for the summation of a constant

ⁿ∑ₐ₎ ₁ (c) = cn

Plug in the values

¹³∑ₙ₎ ₁ (- 1) = (-1)(13)

¹³∑ₙ₎ ₁ (- 1) = -13

Now, we add the results of the summation.

Step-by-step explanation:

The fixed asset turnover ratio for Gemology Inc. is 8.5.

The fixed asset turnover ratio measures how efficiently a company utilizes its fixed assets to generate sales.

It is calculated by dividing net sales by average net fixed assets.

To calculate the average net fixed assets, we sum the net fixed assets at the beginning and end of the period and divide by 2.

Given the information provided,

The net fixed assets at the beginning of the period are $125,000 and the net fixed assets at the end of the period are $75,000.

Therefore, the average net fixed assets would be

($125,000 + $75,000) / 2 = $100,000.

The net sales for Gemology Inc. are $850,000.

Now, we can calculate the fixed asset turnover ratio by dividing net sales ($850,000) by the average net fixed assets

($100,000): $850,000 / $100,000 = 8.5.

Therefore, the fixed asset turnover ratio for Gemology Inc. is 8.5, indicating that the company generates $8.50 of sales for every dollar invested in fixed assets.

The mean of the grouped data is 26.25, the median is 25, and the mode is 20-30.

To find the mean( average) of grouped data, we need to calculate the midpoint of each class interval by adding the lower and upper limits and dividing by 2. Then, we multiply each midpoint by its corresponding frequency and sum up these products. Dividing the total by the sum of the frequencies gives us the mean, which is 26.25 in this case.

To find the median, we first need to determine the cumulative frequency. Starting from the first class interval, we add the frequencies up to each interval to obtain the cumulative frequency. The median falls in the interval where the cumulative frequency exceeds half of the total frequency, which is 15. In this case, it is the 20-30 class interval. We can estimate the median by using the formula: Median = L + ((n/2 - CF) * w), where L is the lower limit of the median class interval, n is the total frequency, CF is the cumulative frequency before the median interval, and w is the width of the interval. Plugging in the values, we find that the median is 25.

The mode represents the most frequent value or interval. In this case, the class interval with the highest frequency is 20-30, with a frequency of 9. Therefore, the mode of the grouped data is 20-30.

Thanks for the points :3

The order of visit for DFS and BFS will differ based on the structure of the graph or tree and the starting node. DFS will typically visit nodes in a deeper order, while BFS will visit nodes in a breadth-first order.

Both  algorithm depth-first search and algorithm breadth-first search are used to traverse or search a graph or tree data structure. The difference between them lies in their traversal strategy.
Depth-first search (DFS) starts at a root node and explores as far as possible along each branch before backtracking. It follows a content-loaded algorithm, meaning that it prioritizes exploring deeper into the structure before considering other branches. In terms of visit order, DFS starts at the root node, then moves to its first child node, and continues to explore its descendants until it reaches a leaf node. Once it has visited all descendants of the current node, it backtracks to the previous node and repeats the process until it has visited all nodes.
On the other hand, breadth-first search (BFS) starts at the root node and explores all the neighboring nodes at the current depth level before moving on to the next depth level. It follows a breadth-first algorithm, meaning that it prioritizes exploring all nodes at a given depth level before moving on to deeper levels. In terms of visit order, BFS visits all nodes at a given depth level before moving on to the next level.

The parametric function for your location on the Ferris wheel at any given time:
x(t) = 80 * sin(2π * (t/2))
y(t) = 80 * cos(2π * (t/2)) + 3

To create a parametric function that models your location on the Ferris wheel at a given time, we need to come up with equations that describe your horizontal and vertical positions as functions of time.

Let's start with the horizontal position. Since the Ferris wheel rotates counter-clockwise, we know that your position on the wheel will increase as time goes on. We can express this as:

x(t) = 80cos(2πt/120)

Here, t represents time in seconds, and the factor of 2π/120 ensures that the function completes one full cycle (i.e. one trip around the wheel) in 120 seconds, or 2 minutes. The cosine function gives us a smooth, periodic curve that oscillates between -80 and 80, corresponding to your position on either side of the wheel's center.

Next, let's consider your vertical position. We know that you start at a height of 3 feet above the ground, and as the wheel rotates, your height will vary sinusoidally over time. We can express this as:

y(t) = 80sin(2πt/120) + 3

Here, the sine function gives us a smooth, periodic curve that oscillates between 77 and 83 feet (i.e. the radius of the wheel plus or minus 3 feet).

So, putting it all together, our parametric function for your location on the Ferris wheel at a given time t is:

(r(t), θ(t)) = (80cos(2πt/120), 80sin(2πt/120) + 3)

Here, r(t) and θ(t) represent your radial distance from the center of the wheel and the angle you've rotated from the starting position, respectively. This parametric function describes a smooth, periodic curve that traces out your path on the Ferris wheel as it rotates counter-clockwise.

Given the information, we know the Ferris wheel has a radius of 80 feet, the bottom is 3 feet above the ground, it rotates counter-clockwise, and has a period of 2 minutes.

To create a parametric function, we need two equations, one for the x-coordinate (horizontal) and one for the y-coordinate (vertical). Let's denote the time variable as t, measured in minutes.

1. X-coordinate (horizontal position):
Since the Ferris wheel rotates counter-clockwise, we can use the following equation for the x-coordinate:
x(t) = 80 * sin(2π * (t/2))

2. Y-coordinate (vertical position):
To account for the bottom of the Ferris wheel being 3 feet above the ground, we need to add 3 to the vertical equation:
y(t) = 80 * cos(2π * (t/2)) + 3

Now, we have the parametric function for your location on the Ferris wheel at any given time:
x(t) = 80 * sin(2π * (t/2))
y(t) = 80 * cos(2π * (t/2)) + 3

The probability P(-1.645 ≤ Z ≤ 1.645) is found to be 0.9.

The random variable X has a continuous uniform distribution f(R) 0, otherwise. A random sample of n-12 observations is chosen from this distribution, and the sample mean X is taken. We assume that the Central Limit Theorem is applicable despite the fact that the sample size n -12 is small.The sample size n -12 is quite small, but we still assume that the Central Limit Theorem is applicable.

To find the approximate probability distribution of Xt, we may use the Central Limit Theorem. A

ccording to the Central Limit Theorem, the sample mean X ~ N(mean, variance/n), assuming that n is sufficiently large.The expected value of the continuous uniform distribution is (a + b)/2, and the variance is (b - a)2/12. In this case, a = 0 and b = R. As a result, we have:The expected value of X is E(X) = (0 + R)/2 = R/2

The variance of X is Var(X) = (R - 0)2/12 = R2/12As a result, by the Central Limit Theorem, the approximate probability distribution of Xt is:N(R/2, R2/12(n-12))We want to find the probability P045. This is the probability that the random variable Z = (Xt - R/2) /sqrt(R2/12(n-12)) is less than -1.645 or greater than 1.645.

This may be accomplished using Table III from Appendix Table III on page 743.The probability P(Z ≤ -1.645) is approximately 0.05.

The probability P(Z ≥ 1.645) is also about 0.05. As a result, the probability P(-1.645 ≤ Z ≤ 1.645) is approximately 0.9.

The solution of this inequality is

Time ≥ 6 hours

Explanation

We are told that the car's maximum speed is 55 miles per hour.

To solve this, we should note that

Speed = (distance/time)

But for this question, we are told that the car has a maximum speed of 55 miles per hour.

So,

(Distance/Time) ≤ 55

If the distance covered is 330 miles

(Distance/Time) ≤ 55

(330/Time) ≤ 55

55 (Time) ≥ 330

Divide both sides by 55

Time ≥ (330/55)

Time ≥ 6 hours
