The area of the pyramid = 340 sq. inches

The area of a square pyramid= b^2+ 2.b.s

                                                  = 10^2 + 2*10*12

                                                  = 340 sq. inches

We can also find out the are by finding area of each sides

Area of square = 10*10 = 100 sq. inches

Area of triangle= 1/2( 12*10)

                           = 60

Area of four triangles = 4*60

                                    = 240

Total surface area = 240+100

                                = 340 sq. inches

Hence the total surface area is 340 sq. inches

Simply use cross multiplication :

The process of multiplying numbers in the shape of a fraction is called cross multiplication. Cross multiplying, also known as cross multiplication, is the process of multiplying the numerator of one fraction by the denominator of the other fraction on the other side of an equal symbol. Cross multiplication is a method for comparing fractions.

Both fractions with like and unlike parts are multiplied across. When employing the cross-multiplication procedure, we multiply the denominators as well as the numerators when a fraction is dissimilar, or when the denominators of two fractions are not alike.

How do you convert 2−2i to polar form?

Answers

2 - 2i can be written in polar form as [tex]2\sqrt{2} \ cis\frac {-3\pi}{4}[/tex]

To convert a complex number in Cartesian form (such as 2 - 2i) to polar form, you can use the following steps:

Find the magnitude (or absolute value) of the complex number. This is the distance from the origin to the point representing the complex number in the complex plane. The magnitude of 2 - 2i is approximately 2.83.Find the argument of the complex number. This is the angle between the positive real axis and the line connecting the origin to the point representing the complex number in the complex plane. To find the argument, you can use the inverse tangent function (also known as arctangent or atan). The argument of 2 - 2i is approximately -135 degrees, or -2.356 radians.Combine the magnitude and argument to express the complex number in polar form. In polar form, a complex number is written as "magnitude (angle)", where the angle is expressed in either degrees or radians. So, the polar form of 2 - 2i is approximately 2.83 (-135 degrees) or 2.83 (-2.356 radians).

How do you find the maclaurin series expansion of f(x)=(1−x)^−2?

Answers

The Maclaurin series expansion of f(x) = 1/(1-x)² is

1 + 2x + 6x² + 24x³ +......

The general expression for the Maclaurin series is given by the formula:

f(x) = f(0) + xf'(0) + x²f''(0) + ..... + xⁿf⁽ⁿ⁾(0)+...

= ∑ f⁽ⁿ⁾ (0)xⁿ/n!

n= 0 to infinity

Specifying the convergence region completes the Maclaurin series formulation. Detailed five steps for determining the Maclaurin series of

f(x) = 1/(1-x)²

Step 1 : Find Derivatives for f(x)

f(x) = 1/(1-x)²

f'(x) = -2(1-x)⁽⁻²⁻¹⁾ (-1) = 2/(1-x)³

The second derivative of f(x) is the derivative of f''(x) :

f"(x) = 2(-3)(1-x)⁽⁻³⁻¹⁾(-1) = 6/(1-x)⁴

Differentiating again, f"'(x) = 6(-4)(1-x)⁽⁻⁴⁻¹⁾(-1)

= 24/(1-x)⁵

Thus, the nᵗʰ derivative is ,

f⁽ⁿ⁾(x) = (n+1)!/(1-x)⁽ⁿ⁻¹⁾

Step 2: Evaluate These Derivatives and f(x) at x=0 let x = 0 , f(0) = 1

f'(0) = 2 , f"(0) = 6 , ....... , f⁽ⁿ⁾(0) = (n+1)!

Step 3 : Now, the Sum of Products :

f(x) = f(0) + xf'(0) + x²f''(0) + ..... + xⁿf⁽ⁿ⁾(0)+...

xf'(0) = 2x

x²f"(0) = 6x²

x³f"'(0) = 24 x³

----------------------------

xⁿf⁽ⁿ⁾(0)= (n+1)!

Thus, the Maclaurin series for ln(1 + x) is this:

f(x) = (1−x)⁻² = 1 + 2x + 6x² + 24x³ +......

Use the drop-down menu below to write an inequality representing cc, the total number of 40-kilogram crates that can be loaded into the shipping container.

Answers

An inequality representing c, the total number of 40-kilogram crates that can be loaded into the shipping container is; 7700 + (40c) ≤ 27500

The maximum number of 40 kg crate is 380.

How to solve Inequality Word Problems?

We are given;

Weight of the crate = 40 kg

Greatest weight that the container can load = 27500 kg

Weight of the other shipments on the container = 7700 kg

The greatest number of 40 kg crates is represented by the letter "c".

Thus;

The weight of the other shipment + weight of crate x number of crates ≤ greatest weight of the container

Plugging in the relevant values gives;

7700 + (40c) ≤ 27500

7700 + 40c ≤ 23000

m/GHI= (x +10)°. Findm/GHI.

Answers

Applying the exterior angles theorem, the measure of angle GHI is: 29°.

What is the Exterior Angle Theorem?

The Exterior Angle Theorem states that the measure of an exterior angle of a triangle is equal to the sum of the measures of the two remote interior angles.

In other words, if a triangle, for example triangle GHI, has angles G, H, and I, and angle HIJ is the exterior angle formed by extending side GI through point I to point J, then the measure of angle HIJ is equal to the sum of the measures of angles IGH and GHI.

Given the following:

m<IGH = (x+16)°,

m<HIJ = (4x – 12)°,

m<GHI= (x +10)°

Therefore:

m<HIJ = m<IGH + m<GHI

Substitute:

4x - 12 = x + 16 + x + 10

4x - 12 = 2x + 26

4x - 2x = 12 + 26

2x = 38

what is the minimum sample size required to estimate a population mean with a confidence of 95%, if the margin of error is 2 units and a standard deviation of 10 units? show formula and your calculations. round to the next whole number.

Answers

The minimum sample size required to estimate a population mean with a confidence of 95%, a margin error of 2 units and a standard deviation of 10 units is 96.

A minimum sample size is the number of participants one needs to maintain their target confidence interval (margin of error) and confidence level while obtaining results that accurately represent the population they are studying.

The formula to calculate the minimum sample size for the population mean is [tex]\bold{n=\left(\frac{z\times \sigma}{E}\right)^2}[/tex]. Here, n is the sample size, z is the confidence level, σ is the standard deviation, and E is the margin error.

Given, the z-value for 95% confidence is 1.96, E is 2 and σ is 10.

Then, the minimum sample size is,

[tex]\begin{aligned}n&=\left(\frac{1.96\times10}{2}\right)^2\\&=(9.8)^2\\&=96.04\\&\approx96\end{aligned}[/tex]

*I can graph it, I just need the equation*

Answers

The linear equation that passes through the points (0,-8) and (5,-5) is:

y = (3/5)*x - 8

How to find the equation of the line?

A general linear equation is written as:

y = a*x + b

Where a is the slope and b is the y-intercept.

If the line passes through two points (x1, y1) and (x2, y2), then the slope is:

a = (y2 - y1)/(x2 - x1)

Here we have the two points: (0,-8) and (5,-5)

Then the slope is:

a = (-5 + 8)/(5 - 0) = 3/5

Answers

The correct answer is : c) As the number of experiments increases, the mean of the observations will approach the mean of the random variable.

Mean of random Variable x :

The expected value of a discrete random variable X, symbolized as E(X), is often called the long-term average or mean (symbolized as μ). This means that if you run the experiment many times over time, you would expect this average. For example, let X = the number of heads you get when you toss 3 fair coins. If we repeat this experiment (tossing 3 fair coins) many times, the expected value of X will be the expected average number of heads per 3 tosses.

Standard Deviation of Random Variable:

A measure of the variance of a random variable distribution that determines how for a value is from its expected value.

The standard deviation of a random variable X is often written as σ or σₓ.

For discrete random variables, the standard deviation is computed by taking the square of the difference between the value of the random variable and the expected value multiplied by the associated probability of the value of the random variable. Calculate the value of a random variable and finally take the square root.

In symbols σ = √ (x - μ)² P(X =x)

The equivalent formula is σ = [tex]\sqrt{E(x^{2}) - [{E(x^2)]}[/tex]

The square of the standard deviation equals the variance Var(X) = σ².

which of the following represents the average rate of change to the function g(x) = 3/2x + 1 over the interval -2 < x < 8

Answers

The average rate of change to the function is (d) 3/2

How to determine the average rate of change to the function?

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

g(x) = 3/2x + 1

Also, we have the interval to be

-2 < x < 8

This interval can be expressed as

a = -2 and b = 8

So, we start by calculating g(-2) and g(8)

Substitute the known values in the above equation, so, we have the following representation

g(-2) = 3/2 * (-2) + 1

g(-2) = -2

Also, we have

g(8) = 3/2 * (8) + 1

g(8) = 13

The average rate of change to the function is then calculated as

Rate = [g(8) - g(-2)]/[8 + 2]

So, we have

Rate = (13 + 2)/(8 + 2)

Evaluate

Rate = 3/2

Hence, the average rate is 3/2

Company manufactures small automobiles that have averaged 45 miles per gallon of gasoline in highway driving

Company now advertises that its new small cars average more than 45 miles per gallon in highway driving

52 automobiles were tested

Sample average is 46.1 miles per gallon

Sample standard deviation is 5.3 miles per gallon

Significance level is 0.01

We have to conduct an appropriate hypothesis test and find the t-statistic and determine the correct conclusion.

Let us assume that -

p = population of average gasoline of new small cars in highway driving

According to the given information,

Null hypothesis represents that the advertising campaign of the manufacturer is incorrect. This implies that -

[tex]H_{0}[/tex] : [tex]p\leq 45[/tex] miles per gallon

Alternative hypothesis represents that the advertising campaign of the manufacturer is correct. This implies that -

[tex]H_{A}[/tex] : [tex]p > 45[/tex] miles per gallon

For carrying out the hypothesis test for the given situation we have to apply one sample z test statistic since the sample standard deviation information is available to us.

According to one sample z test, the value of test statistic is given as -

[tex]T = \frac{(X_{avg} -p)}{\frac{S}{\sqrt{n} } }[/tex] ------ (1)

where,

[tex]X_{avg}[/tex] = Sample mean

p = hypothesized population mean

S = Sample standard deviation

n = Sample size

According to the given information, we have

[tex]X_{avg}[/tex] = 46.1 miles per gallon

p = 45 miles per gallon

S = 5.3 miles per gallon

n = 52

Substituting the above values in equation (1), we have

[tex]T = \frac{(X_{avg} -p)}{\frac{S}{\sqrt{n} } }\\= > T = \frac{(46.1 -45)}{\frac{5.3}{\sqrt{52} } }\\= > T = \frac{1.1}{0.735}\\ = > T = 0.634[/tex]

It is given to us that the significance level is 0.01. According to the z-table, the critical value of the test statistic at 0.01 significance level is 2.58.

But, we see that the test statistic that we obtained above is less than the critical value at significance level of 0.01. i.e.,

0.634 < 2.58

This implies that there is not sufficient evidence for us to reject the null hypothesis for this particular situation.

Therefore, we can conclude from the hypothesis test that the t-statistic is 0.634 and thus, the manufacturer's advertising campaign is incorrect as its new small cars have an average of less than or equal to 45 miles per gallon in highway driving.

erin wants to find the circumference of a circle with radius 7cm . which of following can she use to find the circumference of the circle ?

A. 2x 7 x π
B 2 x 14 x π
C 7/2 x π
D 14 xπ
E. 49 x π

Answers

To find the circumference of a circle with a radius of 7 cm, Erin should use 2×7×π. This is because the circumference of a circle is calculated by the formula 2×π×r.

What is the circumference of a circle?

The circumference is the measure of the perimeter of a circle. Since we know that from every point on the circle to its center has an equal length and is said to be its radius, the perimeter of the circle we can write as

Circumference = 2 × π × r units.

Here r is the radius of the circle.

Calculation:

It is given that Erin wants to find the circumference of a circle with a radius of 7 cm.

So, first, she has to know the formula for finding the circumference.

Here the radius is given as 7 cm i.e., r = 7 cm

Then, the circumference of the given circle is

= 2 × π × r

On substituting the radius value into the above formula, we get

Circumference = 2 × π × 7 cm

⇒ 14π cm

So, she needs to use option A. 2 × 7 × π  for finding the required circumference. This is the first step for finding the circumference of a circle.

Compensation in the United States is governed by a number of laws that set boundaries for what companies can do. Two of the most important are the rules governing equal employment opportunity and the Fair Labor Standards Act (FLSA). In the United States, it is illegal to discriminate on the basis of race, sex, or other protected categories in employment practices, including pay. The 1938 FLSA established the minimum wage, requirements for overtime regulations, and employment of minors. The FLSA establishes periodic minimum wages, of which the latest federal minimum wage is $7.25 per hour as of October 2016, although some exceptions apply for training wages and adherence to state minimum-wage laws. The FLSA also establishes overtime pay for wage earners working over 40 hours per week with detailed computation that includes bonuses and piece-rate payments. These employees are considered nonexempt workers because they are covered under FLSA requirements for overtime pay. Those employees who are not covered are considered exempt employees, usually paid salaries, who are in the executive and other professional white-collar jobs. FLSA rules also govern employment of child labor, outlining details from ages under 14 through 18. Finally, two additional federal laws, the Davis-Bacon Act of 1931 and the Walsh-Healy Public Contracts Act of 1936, govern pay policies of federal contractors. This activity is important because it distinguishes between exempt and nonexempt compensation. The goal of this activity is to match legal requirements with the associated pay policy.
