The length of the fabric which Brandon formed a rectangle, is 11 inches.

To find the length of the fabric, we can use the Pythagorean theorem. The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse (the longest side) is equal to the sum of the squares of the other two sides.

In this case, the length of the fabric is one of the other two sides, and the diagonal cut is the hypotenuse. So, we can write the equation:

\(L^2 + 5^2 = 13^2\)

where L is the length of the fabric.

Solving for L, we get:

\(L^2 = 144 - 25 = 119, and L =\sqrt{119} = 11.\)

Surface Area of a regular pyramid  = Base Area + Lateral Area

To find the surface area of a regular pyramid, we need to use the formulas given below;

Formula 1: Surface Area = Base Area + Lateral Area

Formula 2: Base Area = 1/2 × Perimeter × Slant Height

Formula 3: Lateral Area = 1/2 × Perimeter × Slant Height

Here, the perimeter of the base of the regular pyramid is p, slant height is s, base area is BA, and the lateral area is LA.

Therefore, the formulas that can be used to find the surface area of a regular pyramid where p is the perimeter of the base, s is the slant height, BA is the base area, and LA is the lateral area are:

Surface Area = Base Area + Lateral Area => BA + LA

Lateral Area = 1/2 × Perimeter × Slant Height => 1/2 × p × s

Base Area = 1/2 × Perimeter × Slant Height => BA = 1/2 × p × s

First, we need to convert the mean from hours to minutes, which is 10 * 60 = 600 minutes.

The exponential distribution is given by the formula:

$P(X > x) = e^{-\lambda x}$

where $\lambda$ is the rate parameter, which is equal to 1/mean for an exponential distribution.

Thus, for this problem, we have:

$\lambda = 1/600$

We want to find the probability that the next customer will take more than 5 minutes, or in other words, $P(X > 5)$.

$P(X > 5) = e^{-\lambda \cdot 5} = e^{-(1/600) \cdot 5} \approx 0.991$

Therefore, the probability that the next customer will take more than 5 minutes is approximately 0.991.

Setting x1 to zero in the equation 2x1 + 1x2 = 30 results in the value of x2 being 30.

The given equation is 2x1 + 1x2 = 30, where x1 and x2 represent variables. To find the value of x2 when x1 is set to zero, we substitute x1 with zero in the equation.

By replacing x1 with zero, we have 2(0) + 1x2 = 30. Simplifying further, we get 0 + 1x2 = 30, which simplifies to x2 = 30.

When x1 is set to zero, the equation reduces to a simple linear equation of the form 1x2 = 30. Therefore, the value of x2 in this scenario is 30.

Setting x1 to zero effectively eliminates the contribution of x1 in the equation, allowing us to focus solely on the value of x2. In this case, when x1 is removed from the equation, x2 becomes the sole variable responsible for fulfilling the equation's requirement of equaling 30. Thus, x2 is determined to be 30.

These standardization methods are crucial in chromatography to ensure accurate quantification and comparability of results.

In chromatography, standardization methods are used to ensure accurate and reliable results by establishing reference points or calibration standards. Here are three common methods of standardization in chromatography: External Standardization: In this method, a set of known standard samples with known concentrations or properties is prepared separately from the sample being analyzed. These standards are then analyzed using the same chromatographic conditions as the sample. By comparing the response of the sample to that of the standards, the concentration or properties of the sample can be determined. Internal Standardization: This method involves the addition of a known compound (internal standard) to both the standard solutions and the sample. The internal standard should ideally have similar properties to the analyte of interest but be different enough to be easily distinguished. The response of the internal standard is used as a reference to correct for variations in sample preparation, injection volume, and instrumental response. Internal standardization helps improve the accuracy and precision of the analysis. Standard Addition: This method is useful when the matrix of the sample interferes with the analysis or when the analyte concentration is unknown. It involves adding known amounts of the analyte of interest to different aliquots of the sample. The response of the analyte is then measured, and the concentration is determined by comparing the response with that of the standards. The difference in response between the sample and the standards allows for the determination of the analyte concentration in the original sample.

Step-by-step explanation:

angle <3 is supplementary to 5x + 3

5x + 3 + 21x - 5 = 180 (because two angles are supplementary as well)

26x  - 2 = 180 add 2 to both sides

26x = 182 divide both sides by 26

x = 7

<3 + 5x + 3 = 180 replace x with 7 and rewrite equation

<3 + 38 = 180 subtract 38 from both sides

The mean and standard deviation of sampling distribution are 0.0187 and 0.010 respectively

The mean is a measure of location which tells us the average of observation.

Standard deviation tells us how dispersed a data is or how much variation our data contains.

According to question,

The population size : N = 1500

Number of fraudulent in a month : 28

Population proportion : P = 28/1500

=> P = 0.0187

Sample size: n = 180

Sample proportion : p = 28 / 180

=> p = 0.156

Therefore The mean of sampling distribution for the sample size 28,

μ = P

=> μ = 0.0187

The standard deviation will be

=> σ = \(\sqrt{\frac{p(1-p)}{n}}\)

Substituting the value,

=>  σ = \(\sqrt{\frac{0.0187(1-0.0187)}{180}}\)

Step-by-step explanation:

The only correct solutions within the given interval are x = π/2 and x = π. In the equation cos(x) + 1 = sin(x), we can solve for x within the given interval [0, 2π).

First, let's rearrange the equation to isolate the sine term:

cos(x) - sin(x) + 1 = 0.

Now, let's examine the values of cosine and sine at various points within the interval.

At x = π/2, the cosine is 0 and the sine is 1. Plugging these values into the equation yields 0 + 1 - 1 + 1 = 1 ≠ 0. Therefore, π/2 is not a solution.

At x = π, the cosine is -1 and the sine is 0. Plugging these values into the equation gives -1 + 1 - 0 + 1 = 1 ≠ 0. Thus, π is also not a solution.

At x = 3π/2, the cosine is 0 and the sine is -1. Substituting these values gives 0 + 1 + 1 = 2 ≠ 0. Hence, 3π/2 is not a solution either.

Based on the given Poisson distribution, the probability there is at least one error in a five-page document is 0.981 or 98.2%.

The Poisson distribution refers to a discrete probability distribution that provides the probability of a given number of events occurring in a fixed interval of time or space such that the events happen with a known constant mean rate. The probability formula for Poisson distribution is given by:

P\left(x\right)=\frac{e^{-\lambda}*\lambda^x}{x!}

Where λ is an average rate of value, x is the random variable, and e is the base of the algorithm.

The number of typing errors on a page follows a Poisson distribution. The average of typing errors on a page is 0.8 per page, hence the average rate for five-page document is 0.8*5 = 4 per document. Hence, the probable at least one error is found in the document is given by P(x ≥ 1) = 1 – P(x = 0)

Hence, find the probability that the number of error is 0 is given by:

P\left(0\right)=\frac{e^{-4}*4^0}{0!}\ =\ e^{-4}

Therefore,

P(x\ \geq\ 1)\ =\ 1\ -\ e^{-4}\ =\ 0.981

The point-slope formula will be used to determine the equation that models the cost of each plans.

(y - y₁) = [(y₂ - y₁)/(x₂ - x₁)](x - x₁)

where (x₁, y₁) is the coordinates of point 1

(x₂, y₂) is the coordinates of point 2.

For the equation y = mx + b,

let x = number of discs rented

y = total cost

m = rental rate per disc

b = one-time membership fee

Plan A

(y - 14) = [(17 - 14)/(2 - 1)](x - 1)

y - 14 = 3x - 3

y = 3x + 11

A Type I error is committed when the scientist concludes that the antipollution device is effective when it actually is not. This can happen if the scientist sets the significance level too low, or if there is a lot of random variation in the data.

The null hypothesis in this case is that the antipollution device is not effective. The alternative hypothesis is that the antipollution device is effective. If the scientist rejects the null hypothesis, they are saying that they have enough evidence to conclude that the antipollution device is effective. However, if the null hypothesis is actually true, then the scientist has made a Type I error.

The probability of making a Type I error is typically set at 5%. This means that if the null hypothesis is true, then there is a 5% chance that the scientist will reject it. The significance level can be set higher or lower, depending on how much risk the scientist is willing to take of making a Type I error.

Random variation in the data can also lead to a Type I error. If the data is very noisy, then it can be difficult to tell whether the results are due to the antipollution device or just random chance. This is why it is important to have a large sample size when conducting statistical tests.

Answer: C. Four loaves, with flour left over.

Step-by-step explanation:

7/2 simplifies to 3 1/2

Do the math,

3/4 + 3/4 = 1 1/2        2 loaves

1 1/2 + 3/4 = 2 1/4      3 loaves

2 1/4 + 3/4 = 3           4 loaves

Now when we add 3/4 to 3, we get more than 3 1/2. Which means we do not have enough flour for another loaf of bread. So, we can make four loaves and still have some four left over. The answer is C.
