How do you find the t value of a 95 confidence interval?

Answer:

$5,250 ≤ m ≤ $6,125

Step-by-step explanation:

A compound inequality is a mathematical statement that combines two inequality statements using "and" or "or". In this case, the compound inequality represents the range of possible monthly salary for an entry-level mechanical engineer in Texas.

The average salary for this position ranges from $63,000 to $73,500 per year. To find the monthly salary, we need to divide these amounts by 12 months, which gives us the minimum and maximum monthly salary:

$63,000/12 = $5,250

$73,500/12 = $6,125

Therefore, the compound inequality is:

$5,250 ≤ m ≤ $6,125

This means that the monthly salary of an entry-level mechanical engineer in Texas could be anywhere between $5,250 and $6,125.

The limit does not exist as x approaches 8 for (√(12−x) − 2)/ (√(24−x) − 4).

Therefore the answer is dne.

The square root of 12 - x approaches 2 as x approaches 8 and the square root of 24 - x approaches 4 as x approaches 8.

The limit fails to exist because both the numerator and the denominator approach 0 as x approaches 8, but the ratio of the two approaches positive infinity. This shows that the limit is undefined or "dne".

As both the numerator and denominator approach 0, the fraction they form can approach any real number or it can oscillate between two values, leading to an undefined limit. In such cases, the limit fails to exist.

In its most basic form, an equation is a mathematical statement that indicates that two mathematical expressions are equal. 3x + 5 = 14, for example, is an equation in which 3x + 5 and 14 are two expressions separated by a 'equal' sign.

Here,

Given the regression equation for predicting final-exam score from midterm-exam score:

final = a + b * midterm

where a and b are the regression coefficients, we can use the class mean midterm score x as a reference point to predict the final exam score for a student who scored 10 points above the class mean on the midterm.

First, we need to find the class mean midterm score, which can be represented as x:

x = mean(midterm_scores)

Next, we find the predicted final exam score for the class mean midterm score:

final = a + b * x

Finally, we find the predicted final exam score for a student who scored 10 points above the class mean midterm score:

final = a + b * (x + 10)

Marginal revenue and marginal profit when 2500 widgets are sold is $175 and $-17.5 respectively and when 7500 widgets are sold is $125 and $-207.5 respectively.

The cost function is given by:

C(x)\ =\ 15000\ +\ 100x\ -\ 0.03x^2\ +\ 0.000004x^3

The demand function is given by:

p\left(x\right)=200-0.005x

The marginal revenue and marginal profit are determined by differentiating revenue function R(x) and profit function P(x) respectively. The relationship between cost function C(x), revenue function R(x) and profit function P(x) is:

P(x)\ =\ R(x)\ -\ C(x)

The revenue function is determined by multiplying demand function p(x) and number of widgets x, hence

R(x)\ =xp(x)\ =\ x(200\ -\ 0.005x)\ =\ 200x\ -\ 0.005x^2

The profit function is given by:

P(x)\ =\ (200\ -\ 0.005x^2)\ -\ (15000\ +\ 100x\ -\ 0.03x^2\ +\ 0.000004x^3)

P(x)\ =\ -0.000004x^3\ -\ 0.025x^2\ +\ 100x\ -\ 15000

Differentiating profit function to determine marginal profit:

P\left(x\right)=-0.000004x^3-0.025x^2+100x-15000

P'(x)\ =\ -0.0000012x^2\ -\ 0.05x\ +\ 100

Differentiating revenue function to determine marginal revenue:

R(x)\ =\ 200x\ -\ 0.005^2

R'(x)\ = 200 – 0.01x

Evaluating these differentials when x = 2500 and x = 7500

P'(x)\ =\ -0.0000012x^2\ -\ 0.05x\ +\ 100

P'(2500)\ =\ -0.0000012(2500)^2\ -\ 0.05(2500)\ +\ 100\ =\ -17.5

P'(7500)\ =\ -0.0000012(7500)^2\ -\ 0.05(7500)\ +\ 100\ =\ -207.5

R'(x)\ = 200 – 0.01x

R'(2500)\ = 200 – 0.01(2500) = 175

R^\prime\left(7500\right)=200-0.01\left(7500\right)=125

Hence, marginal revenue and marginal profit when 2500 widgets are sold is $175 and $-17.5 respectively and when 7500 widgets are sold is $125 and $-207.5.

Note: The question is incomplete.

Therefore, the probability that the digit 7 doesn't appear among 100 digits is: P(7 doesn't appear) = (9^100) / (10^100) = 9 / 10

Therefore, the probability that the digit 7 doesn't appear among 100 digits is 9/10, or 90%.

The probability of the sample mean weight is more than 3 pounds away from the 26:

P(x(bar) < 23) + P(x(bar) > 29)  = 0.0030

Now, According to the question;

Sampling Distribution:

As per the central limit theorem, the sampling distribution is approximately normal if the sample is random and the sample size is at least 30, or the population from which the sample is selected, is normally distributed.

We have,

Population mean, μ = 26 pounds

Population standard deviation , σ = 3 pounds

Sample size, n = 9

P(x(bar) < 23) = 0.0015

P(x(bar) > 29) = 0.0015

The probability of the sample mean weight is more than 3 pounds away from the 26:

P(x(bar) < 23) + P(x(bar) > 29)  = 0.0015 + 0.0015

                                                 = 0.0030

If we randomly sample nine 1-year-old boys, the probability of their sample mean weight being less than 23 pounds is 0.0015, and the probability of being greater than 29 pounds is also 0.0015. What is the probability of the sample mean weight being more than 3 pounds away from 26?

The probability for getting the different numbers when two dice are thrown is: 5/6.

The sample space formed by rolling two dice are: 6*6 = 36.

Total number of pairs having same number = (1,1), (2,2),(3,3),(4,4),(5,5),(6,6) = 6 samples.

Thus,

Number of outcomes having different numbers:

36 - 6 = 30

Probability (different numbers) = total number of different number / total outcomes.

Probability (different numbers) = 30 / 36

Probability (different numbers) = 5/6

Thus, the probability for getting the different numbers when two dice are thrown is: 5/6.

Zero is the magnitude of the electric field inside the conducting shell, at a radial distance r where a < r < b.

Each point in space has an electric field associated with it when there is charge existing in any form. E, often known as electric field strength, electric field intensity, or just the electric field, is a mathematical constant that expresses the strength and direction of an electric field.

The electromagnetic region which surround electrically charged particles and acts to either attract or repel all those other positive ions in the field is known as an electric field (or E-field). A systems of charged particles' physical field is also referred to in this phrase.

By applying Gauss law, to the sphere of radius r with dotted lines:

∅(E) = ∫E. dA

∅(E) = E (4πr²) = Q/∈₀

E₁ = Q/4πr²∈₀

The electric field in a conductor is zero. a < r < b has an r value in the conductor.

Classifying polynomials refers to categorizing polynomials based on the degree of the polynomial and the number of terms in the polynomial.

The degree of a polynomial is the highest exponent in the polynomial. Polynomials can be classified into several types, including constant polynomials (degree 0), linear polynomials (degree 1), quadratic polynomials (degree 2), and so on. Adding and subtracting polynomials is the process of combining two or more polynomials by combining like terms. Like terms are terms with the same variable and exponent. To add or subtract polynomials, simply line up the terms with the same variable and exponent and add or subtract the coefficients. The result will be a new polynomial with the combined terms.

For example, to add the polynomials [tex]2x^2 + 3x + 4[/tex] and [tex]-x^2 + 5x - 6[/tex], we line up the terms with the same variable and exponent and add the coefficients:

[tex](2x^2 + 3x + 4) + (-x^2 + 5x - 6) = (2x^2 - x^2) + (3x + 5x) + (4 - 6) \\[/tex]

                                                   [tex]= x^2 + 8x - 2.[/tex]

Gena needs to add 2.5 liters of the 20% solution. Option B is correct.

The equation model is defined as the model of the given situation in the form of an equation using variables and constants.

Let's call the amount of 20% solution that Gena needs to add "x". Then the total amount of solution will be 5 + x liters. The total amount of apple cider vinegar in the solution will be:

0.20x + 0.05(5 + x) = 0.10(5 + x)

Expanding the right side:

0.20x + 0.05 * 5  = 0.10 * 5 + 0.10x

Solving for x:

0.20x - 0.10x   = 0.10 * 5  -0.05 * 5

0.1x = 0.25
x = 2.5

So, Gena needs to add 2.5 liters of the 20% solution. Option B is correct.
