Answer:

m < A = 30 degrees.

Step-by-step explanation:

If we draw  the triangle we see that:

sin A = BC/AC and cos C = BC/AC, so as sin A + cos C = 1 :

BC/AC + BC/AC = 1

Multiplying through by BC:-

2BC = AC

So sin A = BC/AC = BC / 2BC

= 1/2

- giving m < A = 30 degrees.

Answer: 131.7 ft

Step-by-step explanation: use 148 as side measure b, then solve for measure of side a

with two given angles and one given side, use law of sines.

a = b•sin(A)/sin(B) = 131.71071

c = b•sin(C)/sin(B) = 166.89278

if you want to find angle measures:

180-A-B

180-49-58=73

C=73

The length of the string attached to stake B is 166.3 feet.

Trigonometry is mainly concerned with specific functions of angles and their application to calculations. Trigonometry deals with the study of the relationship between the sides of a triangle (right-angled triangle) and its angles.

For the given situation,

An angle of elevation of stake A = 49°

The length of the string attached to stake A,a = 148 feet

An angle of elevation of stake B = 58°

Let the length of the string attached to stake B be b.

Then by law of sines,

\(\frac{Sine A}{a}=\frac{Sine B}{b}\)

On substituting the above values,

⇒ \(\frac{Sine 49}{148}=\frac{Sine 58}{b}\)

⇒ \(b=\frac{(Sine 58)(148)}{Sine49}\)

⇒ \(b=\frac{(0.8480)(148)}{0.7547}\)

⇒ \(b=166.29\) ≈ \(166.3\)

Hence we can conclude that the length of the string attached to stake B is 166.3 feet.

FMECA is a bottom-up hardware approach to risk assessment. It is an inductive, or data-driven, linking elements of a failure chain as follows: Effect of Failure, Failure Mode, and Causes/Mechanisms. To estimate the reliability of software, most software prediction models use the probability density function to predict "Mean Time To Failure."

FMECA is a systematic and structured analytical methodology used to identify potential failures in a system, equipment, process, or product, and to assess the effect and probability of those failures. FMECA stands for Failure Modes, Effects, and Criticality Analysis. FMECA is similar to FMEA (Failure Modes and Effects Analysis) in that it is used to identify failure modes and assess their risk.

However, FMECA goes beyond FMEA by analyzing the criticality of each failure mode. This makes it an effective tool for identifying the most significant failure modes and prioritizing them for corrective action. A Probability Density Function (PDF) is a function that describes the likelihood of a random variable taking on a particular value.

PDF is used in software prediction models to estimate the reliability of software by predicting "Mean Time To Failure" (MTTF). MTTF is the average time between failures of a system, equipment, process, or product.

Step-by-step explanation:

We can reduce the width of the confidence interval by increasing the sample size, reducing the confidence level and decreasing the mean (A, D, and F)

A confidence interval is an estimate of the interval that has a specified probability of including an unknown population parameter.

The purpose of a confidence interval is to estimate the true value of the population parameter being measured, such as a mean, a standard deviation, or a proportion.

In general, a wider confidence interval indicates more uncertainty about the estimate, while a narrower confidence interval suggests more precision in the estimate.

We want narrower confidence intervals to demonstrate more precision, as this allows us to draw more reliable conclusions about population parameters.

We cannot reduce the width of the confidence interval by increasing the sample size, increasing the confidence level or increasing the mean.

Thus, the correct options are a, d, and f.

The chi-square distribution of Y having 32 degrees of freedom, in a way that its variance is 64 and also P (Y > c) = 0.0668, then the approximate value of the constant c is calculated to be 2060.08.

We are aware of the fact that Y has a chi-square distribution with 32 degrees of freedom and an d has variance 64.  So, the mean of Y is equal to its degrees of freedom times its variance, which can be calculated 32 x 64 = 2048.

Also the constant c can be expressed as Y0 such that P(Y > Y0) = 0.0668. Since Y is a continuous distribution, Chi-square table can be utilized to find out the value of Y0 that is related to this probability.

We can find that the critical value of chi-square with 32 degrees of freedom and a probability of 0.0668 is 44.12. Hence, Y0 can be approximated as :

Y0 ≈ mean + standard deviation x z-score

Here, z-score is the number of standard deviations distant from the mean that corresponds to the probability of 0.0668. We can find the z-score by comparing the probability in a standard normal distribution table, which gives us a z-score of approximately 1.51.

The standard deviation of Y can be found using the calculation of square root of its variance, i.e.  8. Therefore, we can insert these values to find,

Y0 ≈ 2048 + 8 x 1.51 ≈ 2060.08

So from the above calculations it can be inferred that the value of the constant c  for the given chi-square distribution as per the mentioed conditions will be approximately equal to 2060.08.

The multiplicity of a root r of the characteristic equation of A is called the algebraic multiplicity of r as an eigenvalue of A.

The above statement is True.

Eigenvalue:

An eigenvalue is a special set of scalar values ​​associated with the most probable system of linear equations in a matrix equation. Eigenvectors are also called eigenvalues. It is a non-zero vector which can be modified by at most its scalar factor after applying a linear transformation.

According to the Question:

If the geometric multiple of the eigenvalues ​​is greater than or equal to 2, the linearly independent set of eigenvectors is no longer unique to the multiple as before. For example, for the diagonal matrix A=[3003], one could also choose the eigenvectors [11] and [1−1], or any pair of two linearly independent vectors.

Sometimes vectors are simply expanded to vector times matrix. If this happens, this vector is called the eigenvector of the matrix and the "stretch factor" is called the eigenvalue. Example: Given a square matrix A, λ is the eigenvalue of A, and the corresponding eigenvector x is

Answer:

12.25 \(\leq\) x < 12.35

Step-by-step explanation:

5 is the cut off when rounding.

If a number to the right is greater than or equal 5, you round up.

If it's less than 5, you drop the number.

So 12.25 would be rounded up to 12.3

12.34 would be rounded to 12.3

How do you get the 12.25?

Subtract .05 from 12.3

How do you get 12.35?

Add .05 to 12.3.

The number in the hundredths place needs to be less than 5 to round down. That's why you use less than symbol.

We can say with 99% confidence that the true mean price of all transactions is between $2,799.16 and $3,000.84.

To obtain a 99% confidence interval for the mean price of all transactions, we can use the formula:

CI =  ± z*(σ/√n)

Where:
= sample mean price = 2900 dollars
σ = population standard deviation = 290 dollars
n = sample size = 30
z = z-score for a 99% confidence level = 2.576 (from the standard normal distribution table)

Substituting these values into the formula, we get:

CI = 2900 ± 2.576*(290/√30)

When the parallel lines are cut by a transversal, the values for the measurement of ∠2 and ∠4 is 124° each.

What are parallel lines?

Two lines in the same plane that are equally spaced apart and never cross each other are said to be parallel lines in geometry. Both horizontal and vertical shapes are possible.

Examples of parallel lines can be found everywhere, including zebra crossings, rows of notebooks, and the nearby railroad tracks.

In the given diagram the parallel lines are cut by a transversal.

The measure of angle 5 is, m∠5 = 56°.

It is known that each pair of interior angles on the same side of a transversal that cuts two parallel lines are supplementary, or they add up to 180 degrees.

So, m∠5 + m∠2 = 180°

56° + m∠2 = 180°

m∠2 = 180° - 56°

m∠2 = 124°

Now, as it can be seen in the image ∠2 and ∠4 are vertically opposite angles.

So, they will be congruent or equal to each other.

So, it is obtained that -

m∠2 = m∠4

m∠4 = 124°

Therefore, the measures of angles are m∠2 = 99° and m∠4 = 99°.
