Answer:

x = 9

Step-by-step explanation:

First equation = 4x - 8

Second equation = 7x - 35

Seperate the equation with an equal sign to make it an equality equation and solve for X so :

4x - 8 = 7x - 35 (Given)

-3x - 8 = -35 (Subtraction property of equality)

-3x = -27 (Addition property of equality)

x = 9 (Division property of equality)

The reasonable domain for the function is (b) x > 0

From the question, we have the following parameters that can be used in our computation:

The function f(x) = 75x + 100

Where x is the number of hours

f(x) is the total cost.

In this case, the number of hours cannot be negative or 0

This means that the values of x in the function would be x > 0

These values of x are the domain

So, the reasonable domain for the function os (b) x > 0

The input value for the expression is 1 and the remainder is -15.

The Remainder Theorem begins with an unnamed polynomial p(x), where "p(x)" simply means "some polynomial p with variable x". The Theorem then discusses dividing that polynomial by some linear factor x a, where an is simply a number.

Given polynomial is 5x⁴⁵ - 3x¹⁷ +2x⁴ - 19 and is divided by x + 1. Find the value of the polynomial at 1 and then calculate the remainder by synthetic solution.

F(x) = 5x⁴⁵ - 3x¹⁷ +2x⁴ - 19

F(1) = 5 - 3 + 2 - 19

F(1) = -19 + 4

F(1) = -15

The expression (-9x)^4 can be represented as -6561x^3 without using exponents.

To express the expression (-9x)^4 without using exponents, we can expand it by multiplying the base (-9x) four times using the multiplication property.

(-9x)^4 = (-9x) * (-9x) * (-9x) * (-9x)

To simplify this expression, we can multiply the terms together, taking care to apply the rules of multiplication:

(-9x) * (-9x) = (-9 * -9) * (x * x) = 81 * x^2 = 81x^2

So, by substituting this result back into the original expression, we get:

(-9x)^4 = 81x^2 * (-9x) = -6561 x^3

Therefore, the expression (-9x)^4 can be represented as -6561x^3 without using exponents.

Explanation:

We were given the expression:

We are to solve for its modulus. This is shown below:

The best selection for the quadrilateral with the given vertices is: parallelogram.

Recall:

Parallel lines are lines do not intersect and they are equal distant apart.

The opposite side of a parallelogram are of equal length.

Thus, the points of the vertices of the quadrilateral has been graphed in the diagram shown below:

Point A (-2,0)

Point B (0,4)

Point C (6,4)

Point D (4,0)

Find the distance between each vertices using the distance formula: \(d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}\)

Distance between Point A (-2,0) and Point B (0,4):

\(AB = \sqrt{(0 -(-2))^2 + (4 - 0)^2} \\\\\mathbf{AB = \sqrt{20} }\)

Distance between Point B (0,4) and Point C (6,4):

\(BC = \sqrt{(6 - 0)^2 + (4 - 4)^2} \\\\\mathbf{BC = 6 }\)

Using the same distance formula, CD = √20 while AD = 6

This means that the opposite sides of the quadrilateral with the given vertices are equal in length. Parallelogram has two pairs of equal sides.

Therefore, the best selection for the quadrilateral with the given vertices is: parallelogram.

Answer:

To solve the quadratic equation x² + 10x + 24 = 0 by factoring, we need to find two numbers that multiply to 24 and add to 10. These numbers are 6 and 4, so we can write:

x² + 10x + 24 = (x + 6)(x + 4) = 0

Now we can apply the zero product property and set each factor equal to zero:

x + 6 = 0 or x + 4 = 0

Solving for x, we get:

x = -6 or x = -4

Therefore, the solutions to the quadratic equation x² + 10x + 24 = 0 are x = -6 and x = -4.

Answer:

0.89

Step-by-step explanation:

Question says components have reliability of 0.97 and each component works independently.

We are required to calculate probability that the assembly works

We solve this using the binomial distribution

P(X=4)

4C4(0.97)⁴(1-0.97)^4-4

4C4 = 1

0.97⁴ = 0.8859281

1-0.97^4-4 = (0.03)⁰ = 1

Multiply all values

1 x 0.88529281 x 1

= 0.88529281

When approximated, we get 0.89

In conclusion the probability that the assembly works is 0.89

Step-by-step explanation:

Use equation: y = mx + b, where "m" is the slope and "b" is the y intercept. You are given a slope of -1 for the m. This is usually expressed as just a "-", as the 1 is inferred.

Since you are given a point, plug the x and y values in to the equation.

Solve for b:

-7 = -5 + b

-2 = b

The statement ∬S curl F • dS = 0 holds true, as a special case of Stokes' theorem, when F has continuous second partial derivatives and S is the boundary surface of a simple solid region.

The given statement is a special case of Stokes' theorem, which relates the circulation of a vector field around a closed loop to the flux of the curl of the vector field through the surface bounded by the loop.

Stokes' theorem states:

∮C F • dr = ∬S curl F • dS

Where:

In this case, we are given that F has continuous second partial derivatives, and S is the boundary surface of a simple solid region. Let's assume that S is a closed surface, so that it forms a complete boundary around the solid region.

Since S is a closed surface, it has no boundary, and the line integral of F around the loop C is zero:

∮C F • dr = 0

By Stokes' theorem, this implies that the surface integral of the curl of F over the surface S is also zero:

∬S curl F • dS = 0

Answer:

a) H0: p1 - p2 = 0

H1: p1 - p2 ≠ 0

b) z=-0.58

c) p-value = 0.562

Step-by-step explanation:

We need to determine whether p1 is not equals p2, so the null and alternative hypothesis are:

H0: p1 - p2 = 0

H1: p1 - p2 ≠ 0

Where p1 and p2 are the proportions of the population. Additionally, the proportions of the sample p1' and p2' are calculated as:

\(p1'=\frac{x1}{n1}=\frac{28}{254}=0.1102\\p2'=\frac{x2}{n2}=\frac{38}{301}=0.1262\)

Then, the test statistic is calculated using the following equation:

\(z=\frac{(p1'-p2')-(p1-p2)}{\sqrt{p'(1-p')(\frac{1}{n1}+\frac{1}{n2})} }\)

Where p' is calculated as:

\(p'=\frac{x1+x2}{n1+n2}=\frac{28+38}{254+301}=0.1189\)

So, replacing the values, we get that the test statistic is:

\(z=\frac{(0.1102-0.1262)-(0)}{\sqrt{0.1189(1-0.1189)(\frac{1}{254}+\frac{1}{301})}}=-0.58\)

Finally, using the standard normal table, the p-value is equal to:

\(p-value=2*P(z<-0.58)=2*0.281=0.562\)

The p-value is greater that the value of alpha 0.1, so we can't reject the null hypothesis and there is evidence to said that p1 and p2 are equals.

Answer: 20t +4

Step-by-step explanation:

The null and alternative hypothesis for a physician who check your blood pressure are as follows:

When a physician checks a patient's blood pressure, they may use a diagnostic threshold of 90 mmHg to diagnose hypertension. In statistical terms, the null hypothesis (H0) would be that the patient's blood pressure is less than or equal to 90 mmHg. The alternative hypothesis (H1) would be that the patient's blood pressure is greater than 90 mmHg.

The physician would then use various statistical tests, such as a t-test or a z-test, to determine whether the patient's blood pressure is statistically significantly different from the threshold of 90 mmHg. Based on the results of the test, the physician would either reject the null hypothesis in favor of the alternative hypothesis, indicating that the patient has hypertension, or fail to reject the null hypothesis, indicating that the patient's blood pressure is within the normal range.
