What is mean?

In statistics, mean is a measure of central tendency that represents the average value of a set of numbers. It is calculated by summing up all the numbers in the set and dividing the sum by the total number of values in the set. Mean is also commonly referred to as the arithmetic mean. It is a commonly used statistical measure in many fields including finance, economics, social sciences, and more.

Here,

To calculate the z-scores associated with each student, we first need to calculate the sample mean and standard deviation for the Distance to Work variable:

Sample mean: (0+0+5+10+15+30+32)/7 = 10.71

Sample standard deviation: √(((0-10.71)² + (0-10.71)² + (5-10.71)² + (10-10.71)² + (15-10.71)² + (30-10.71)² + (32-10.71)²)/6) = 10.72

Now we can calculate the z-scores for each student:

Student 1: (0 - 10.71) / 10.72 = -0.94

Student 2: (0 - 10.71) / 10.72 = -0.94

Student 3: (5 - 10.71) / 10.72 = -0.53

Student 4: (10 - 10.71) / 10.72 = -0.07

Student 5: (15 - 10.71) / 10.72 = 0.40

Student 6: (30 - 10.71) / 10.72 = 1.80

Student 7: (32 - 10.71) / 10.72 = 1.98

Student 8: (8 - 10.71) / 10.72 = -0.25

Student 9: (36 - 10.71) / 10.72 = 2.37

Student 10: (9 - 10.71) / 10.72 = -0.16

Student 11: (22 - 10.71) / 10.72 = 1.05

Student 12: (10 - 10.71) / 10.72 = -0.07

Student 13: (15 - 10.71) / 10.72 = 0.40

Student 14: (28 - 10.71) / 10.72 = 1.54

Student 15: (12 - 10.71) / 10.72 = 0.12

Student 16: (6 - 10.71) / 10.72 = -0.44

Student 17: (0 - 10.71) / 10.72 = -0.94

Student 18: (10 - 10.71) / 10.72 = -0.07

Student 19: (30 - 10.71) / 10.72 = 1.80

Student 20: (0 - 10.71) / 10.72 = -0.94

To identify potential outliers, we can look for z-scores that are more than 2 standard deviations away from the mean (i.e., greater than 2 or less than -2). From the list above, we can see that Students 6, 7, 9, and 19 have z-scores greater than 2, indicating that they may be potential outliers.

For the second sample of seven data points (0, 0, 5, 10, 15, 30, 32), the mean is 11.14 and the standard deviation is 12.05. Using a t-distribution with 6 degrees of freedom (n-1), the 95% confidence interval is (-7.54, 29.82).

8. Daisy is trying to figure out how much negotiating room she has in purchasing a new car. The car has an MSRP of $34,995.99. She has learned from an industry insider that most car dealerships have a 20% markup on selling price. What does she estimate the dealership paid for the car?

Answers

Answer:

To estimate the dealership's cost for the car, we need to first calculate the dealership's selling price. We know that the car has an MSRP of $34,995.99, and we know that dealerships typically have a 20% markup on selling price.

So, to find the dealership's selling price, we can use the formula:

Selling price = MSRP + (Markup percentage * MSRP)

Substituting the values we have:

Selling price = $34,995.99 + (20% * $34,995.99)

Selling price = $34,995.99 + $6,999.20

Selling price = $41,995.19

Therefore, we estimate that the dealership paid $41,995.19 - the 20% markup - for the car.

To check this estimate, we can calculate the dealership's cost using the formula:

Cost = Selling price - Markup

Substituting the values we have:

Cost = $41,995.19 - (20% * $41,995.19)

Cost = $41,995.19 - $8,399.04

Cost = $33,596.15

This is very close to the MSRP of $34,995.99, which suggests that our estimate is reasonable.

P12 000 is deposited in an account earning 4% interest per year. What is the amount
after 15 years

Answers

Answer:

After 15 years, the amount in the account will be $21.611.32, assuming the interest is compounded annually.

Step-by-step explanation:

To calculate the amount after 15 years, we can use the formula for compound interest:

A = P(1 + r/n)^(nt)

where A is the amount, P is the principal (initial amount), r is the annual interest rate (as a decimal), n is the number of times the interest is compounded per year, and t is the time (in years).

In this case, P = $12,000, r = 0.04 (4% expressed as a decimal), n = 1 (compounded annually), and t = 15 years.

Plugging in the values, we get:

A = $12,000(1 + 0.04/1)^(1*15)

A = $12,000(1.04)^15

A = $12,000(1.801)

A = $21,611.32

Therefore, after 15 years, the amount in the account will be $21.611.32, assuming the interest is compounded annually.

Write a polynomial function of the least degree with integral coefficients that have the given zeros.1+3i,-2i

Answers

The polynomial function of the least degree with integral coefficients that has the zeros [tex]1 + 3i[/tex], [tex]-2i[/tex] is f(x) = x⁴ - 2x³ + 14x² - 8x + 40.

Writing a polynomial function of the least degree

From the question, we are to write a polynomial function of the least degree with integral coefficients that have the given zeros.

The given zeros are [tex]1+3i[/tex],[tex]-2i[/tex].

If [tex]1 + 3i[/tex] and [tex]-2i[/tex]are zeros of a polynomial function with integral coefficients, then their conjugates [tex]1 - 3i[/tex] and [tex]2i[/tex] are also zeros of the function.

To find the polynomial function, we can use the fact that if r is a zero of a polynomial function, then (x - r) is a factor of the function. Thus, we can start by writing out the factors corresponding to each of the zeros:

[tex](x - (1 + 3i))(x - (1 - 3i))(x - (-2i))(x - 2i)[/tex]

Next, we can simplify these factors by multiplying them out:

[tex][(x - 1) - 3i][(x - 1) + 3i](x + 2i)(x - 2i)\\= [(x - 1)^2 - (3i)^2](x^2 - (2i)^2)[/tex]

= [(x - 1)² + 9](x² + 4)

Expanding the terms, we get:

(x² - 2x + 10)(x² + 4)

Multiplying out the factors, we obtain:

x⁴ - 2x³ + 10x² + 4x² - 8x + 40

Simplifying this expression, we get:

x⁴ - 2x³ + 14x² - 8x + 40

Hence, the polynomial function is f(x) = x⁴ - 2x³ + 14x² - 8x + 40

[tex]\mathrm{y\:=\:\frac{3}{2}x\:+\:7}[/tex]

Step-by-step explanation:

To find the equation of a line parallel to -4y = 32 - 6x, we first need to rewrite this equation in slope-intercept form, y = mx + b, where m is the slope and b is the y-intercept.

-4y = 32 - 6x

Divide both sides by -4:

y = -8 + (3/2)x

So the slope of this line is 3/2. Since we want a line parallel to this one, it will have the same slope of 3/2.

Now we can use the point-slope form of a linear equation to find the equation of the line that passes through (0,7) with a slope of 3/2:

y - y1 = m(x - x1)

where m = 3/2 and (x1,y1) = (0,7)

y - 7 = (3/2)(x - 0)

Simplifying:

y - 7 = (3/2)x

y = (3/2)x + 7

So the equation of the line parallel to -4y = 32 - 6x that passes through the point (0,7) is y = (3/2)x + 7.

As economy of coal, electric, and steel industries.

The sales demand is estimated to be $1 billion for coal, $1 billion for electricity, and $4 billion for steel. Suppose that the demand for electricity triples and demand for coal doubles, whereas the demand for for steel increases by only 50%. At what levels should the various industries produce in order to satisfy the new demand.

Answers

Answer:

Step-by-step explanation:

Let’s denote the production levels of coal, electricity and steel as x, y and z respectively. We can set up a system of equations to represent the inter-industry demand for each industry’s output.

For coal: 0.02x + 0.04y + 0.10z = x For electricity: 0.30x + 0.04y = y For steel: 0.30x + 0.02y + 0.04z = z

Solving this system of equations gives us x = (50/3)y and z = (25/2)y.

The new sales demand for coal is $2 billion (double the original), for electricity is $3 billion (triple the original) and for steel is $6 billion (an increase of 50%). Substituting these values into our equations gives us:

(50/3)y = $2 billion y = $3 billion (25/2)y = $6 billion

Solving these equations gives us y = $3 billion, x = $5 billion and z = $18.75 billion.

So to satisfy the new demand, the coal industry should produce at a level of $5 billion, the electric industry should produce at a level of $3 billion and the steel industry should produce at a level of $18.75 billion.

The demand equation for a certain commodity is given by the
following equation.
p= =1/2+². - 20x + 1200, 0≤x≤ 120
Find x and the corresponding price p that maximize revenue.
The maximum value of R(x) occurs at x =0.

Answers

In the given demand equation, the value of x and corresponding price p that maximize revenue are x = 31.8 and p = $514.60.

How to Solve the Equation?

To find the value of x and corresponding price p that maximize revenue, we first need to determine the revenue function. Revenue (R) is given by the product of price (p) and quantity demanded (x), so:

R(x) = xp

Substituting the given demand equation for p, we get:

R(x) = x(1/2 + ² - 20x + 1200)

Simplifying and rearranging:

R(x) = 1/2x + ²x - 20x² + 1200x

R(x) = -20x² + (1200 + ²)x + 1/2x

To find the value of x that maximizes revenue, we take the derivative of R(x) with respect to x, set it equal to zero, and solve for x:

dR/dx = -40x + (1200 + ²) + 1/2 = 0

Solving for x:

x = (1200 + ² + 1/2) / 40

x = 31.8

To find the corresponding price, we substitute this value of x back into the demand equation for p:

p = 1/2 + ² - 20(31.8) + 1200

p = $514.60

Therefore, the value of x and corresponding price p that maximize revenue are x = 31.8 and p = $514.60.

Find the general solution to the differential eauation y 0 cos x = y sinx+sin 175x Assume x ∈ (−π/2,π/2), and use C (capital C) for your arbitrary constant.

Answers

The general sοlutiοn tο the differential equatiοn is [tex]\mathrm{y = Ce^{(sin(x))}}[/tex].

Describe Differentiatiοn?

The derivative οf a functiοn represents the instantaneοus rate οf change οf the functiοn at a specific pοint. It is calculated by finding the limit οf the difference quοtient as the interval between twο pοints οn the functiοn apprοaches zerο. The derivative can be expressed as a functiοn οf the independent variable, and it prοvides valuable infοrmatiοn abοut the behaviοr οf the οriginal functiοn.

The prοcess οf differentiatiοn invοlves applying a set οf rules tο functiοns tο οbtain their derivatives. These rules include the pοwer rule, prοduct rule, quοtient rule, chain rule, and οther mοre advanced rules that are used tο differentiate mοre cοmplex functiοns.

Tο sοlve the given differential equatiοn, we can use the methοd οf integrating factοrs.

First, we can rewrite the equatiοn as:

y'cοsx = ysinx + sin(175x)

Next, we can multiply bοth sides by the integrating factοr, which is [tex]e^{(\int(cos(x) dx))} = e^{(\sin(x) + C)}[/tex], where C is a cοnstant οf integratiοn:

[tex]\mathrm {e^{(sin(x)) }y'cosx = e^{(sin(x))} ysinx + e^{(sin(x))}sin(175x) + Ce^{(sin(x))}}[/tex]

Nοw, we can recοgnize the left-hand side as the derivative οf [tex]e^{(sin(x))}y[/tex]:

[tex](e^{(sin(x))y)}' = e^{(sin(x))} y' + cos(x) e^{(sin(x))}y[/tex]

Substituting this intο the abοve equatiοn, we get:

[tex]\mathrm{(e^{(sin(x))y)}' = e^{(sin(x)) }ysinx + e^{(sin(x))}sin(175x) + Ce^{(sin(x))}}[/tex]

[tex]cos(x) e^{(sin(x))}y = e^{(sin(x))y)}'[/tex]

Separating variables and integrating bοth sides, we get:

[tex]\int e^{sin(x) }dy/y = \int cos(x) dx[/tex]

ln|y| + C = sin(x) + C'

where C' is anοther cοnstant οf integratiοn.

Therefοre, the general sοlutiοn tο the differential equatiοn is:

[tex]\mathrm{|y| = e^{(sin(x)) }e^{(C' - sin(x))}}[/tex]

[tex]\mathrm{y = \± e^{(C' - sin(x) + sin(x))}}[/tex]

[tex]\mathrm{y = Ce^{(sin(x))}}[/tex]

where C is an arbitrary cοnstant.

Find the linear function with the following properties.

f(0)=8
Slope of f=−6

Answers

The linear function with the given properties is: f(x) = 8 - 6x.

What is linear function?

A linear function is a mathematical equation that describes a straight line when graphed. It is the most basic type of function, where the output is equal to the input multiplied by a constant, known as the slope, and a constant added, known as the y-intercept. Linear functions are used to model relationships between two quantities and can be used to describe a wide range of phenomena, from physical properties to economic trends.

This linear function is used to calculate the value of a variable (x) when given the starting value of the function (f(0)) and the slope of the line (the rate at which the value of the function changes for each unit increase in x). In this case, the starting value of the function (f(0)) is 8, and the slope of the line is -6, meaning that the value of the function decreases by 6 for each unit increase in x. Therefore, the linear function that satisfies these properties is f(x) = 8 - 6x.

x 2 −51=14xx, squared, minus, 51, equals, 14, x 1) Rewrite the equation by completing the square.

Answers

Answer:

  (x -7)² = 100

Step-by-step explanation:

You want to rewrite the equation x² -51 = 14x by completing the square.

Complete square

When we're finished, the equation will be of the form ...

  (x +a)² = b

Expanding this, we have ...

  x² +2ax +a² = b

That is, the value of 'a' is half the coefficient of x when the equation is written with the x-terms together.

Rearrangement

Adding 51 -14x to both sides of the given equation, we get ...

  x² -51 = 14x

  x² -14x = 51

Now, we can see that a=-14/2 = -7. We can add a² = (-7)² = 49 to both sides to complete the square:

  x² -14x +49 = 51 +49

  (x -7)² = 100 . . . . . . . rewritten equation

Use the drawing tools to form the correct answer on the provided graph.
Given the equation of the parabola x = -1/8(y - 3)^2 + 1, graph its focus and directrix.

Answers

Using drawing tools parabola graph has been made and uploaded in answer for the given equation.

Standard form of parabola having vertical axis of symmetry given by:

[tex](y - k)^2 = 4p(x - h)[/tex]

where (h, k): vertex and p: distance between the vertex and the focus or directrix.

Comparing the given equation[tex]x = -1/8(y - 3)^2 + 1[/tex] with the standard form, we can see that the vertex is at (1, 3) and p = -1/32.

Since the parabola opens to the left, the focus is to the left of the vertex at a distance of p = -1/32 units. Thus, the focus is located at (-1/32, 3).

The directrix is a vertical line to the right of the vertex and is located at a distance of p = -1/32 units. Thus, the directrix is the vertical line x = 33/32.

To graph the focus and directrix, we can plot the vertex (1, 3) on the coordinate plane, draw a horizontal line through the vertex, and then plot the focus (-1/32, 3) to the left of the vertex and the directrix x = 33/32 to the right of the vertex.

Note that the parabola [tex]x = -1/8(y - 3)^2 + 1[/tex] is symmetric with respect to the vertical line passing through the vertex.

A tree on a hillside casts a shadow c = 235 ft down the hill. If the angle of inclination of the hillside is b = 26° to the horizontal and the angle of elevation of the sun is a = 56°, find the height of the tree. (Round your answer to the nearest foot.)

Answers

The height of the tree is equal to 210 ft to the nearest foot using the sine rule.

What is the sine rule

The sine rule is a relationship between the size of an angle in a triangle and the opposing side.

angle opposite of the tree = 56 - 26 = 30

angle opposite of the shadow = 180 - 90 - 56= 34

by application of sine rule:

sin 30/h = sin 34/235

h = (235 × sin 30)/sin 34 {cross multiplication}

h = 117.5/0.5592

h = 210.1216 ft.

Therefore, the height of the tree is equal to 210 ft to the nearest foot using the sine rule.

Given: If A AND B, then C. Given: The if-then statement's reverse isalso correct. If A is True, B is True, what is C?

Answers

The conclusion is that if A is true, B is true, then C must be true as well.

What is statement ?

In logic and mathematics, a statement is a declarative sentence that is either true or false. It is an assertion about a fact or a relationship between facts. A statement can be a simple sentence, such as "The sun is shining," or a complex one, such as "If it rains tomorrow, I will stay indoors."

If the statement "If A AND B, then C" is true, and if its reverse statement is also true, then the converse of the statement is "If C, then A AND B."

If A is true and B is true, then A AND B is also true. Therefore, by the original statement, C must also be true.

Therefore, the conclusion is that if A is true, B is true, then C must be true as well.
