Answers

Answer 1

An equation in slope-intercept form of the line that passes through (-3, 2) and (-2, - 5) is: C. y = -7x - 19.

How to determine an equation of this line?

In Mathematics and Geometry, the point-slope form of a straight line can be calculated by using the following mathematical equation:

y - y₁ = m(x - x₁)

Where:

m represent the slope.x and y represent the points.

First of all, we would determine the slope of this line;

Slope (m) = (y₂ - y₁)/(x₂ - x₁)

Slope (m) = (-5 - 2)/(-2 + 3)

Slope (m) = -7/1

Slope (m) = -7

At data point (-3, 2), a linear equation in slope-intercept form for this line can be calculated as follows:

y - y₁ = m(x - x₁)

y - 2 = -7(x + 3)

y = -7x - 21 + 2

y = -7x - 19

A step has a height of 5 inches. A ramp starts 4 feet away from the base of the step, making a 5.9° angle with the ground. What can
you say about the angle the ramp would make with the ground if the ramp starts farther away from the step?

Answers

the ramp gets further away from the step, the angle it has with the ground decreases.

θ = [tex]tan^{-1}[/tex](0.515 / (48 + x))

How to find the angle that the ramp would make with the ground?

Assuming that the ramp remains the same height as the step, we can use trigonometry to find the angle that the ramp would make with the ground if it starts farther away from the step.

First, let's convert the distance from feet to inches, since the height of the step is given in inches: 4 feet = 48 inches.

Next, we can use the tangent function to find the angle theta:

tan(θ) = opposite / adjacent

where opposite is the height of the step (5 inches) and adjacent is the horizontal distance from the base of the step to the point where the ramp meets the ground (48 inches * tan(5.9°) = 5.514 inches).

So, tan(θ) = 5 / 5.514, which gives us θ = 41.2°.

Now, let's say the ramp starts at a distance x from the base of the step. We can use the same formula, but with a different value for adjacent:

tan(θ) = 5 / (48 + x) * tan(5.9°)

We can simplify this expression by substituting the value of tan(5.9°) as approximately 0.1032:

tan(θ) = 0.515 / (48 + x)

Solving for theta, we get:

θ = [tex]tan^{-1}[/tex](0.515 / (48 + x))

As a result, we can see that the denominator of the fraction within the arctan function gets larger as x increases (i.e., the ramp starts further from the step), resulting in a smaller fraction and, consequently, a smaller angle theta. To put it another way, as the ramp gets further away from the step, the angle it has with the ground decreases.

cubic foot.
Answer:
-3 ft
-2 ft
10 ft

Answers

Step-by-step explanation:

The volume of a cone is given by the formula (1/3)πr^2h, where r is the radius of the base and h is the height. So, the volume of the cone is:

V_cone = (1/3)π(2 ft)^2(3 ft)

V_cone = (4/3)π ft^3

The volume of a cylinder is given by the formula πr^2h, where r is the radius of the base and h is the height. So, the volume of the cylinder is:

V_cylinder = π(2 ft)^2(10 ft)

V_cylinder = 40π ft^3

To find the total volume, we add the volumes of the cone and cylinder:

V_total = V_cone + V_cylinder

V_total = (4/3)π + 40π

V_total = 133.2 ft^3

Rounding off the answer to the nearest tenth of a cubic foot, the total volume is approximately 133.2 ft^3.

Answer: 138.23 ft³

Step-by-step explanation:

V = V of Cylinder + V of Cone

V of Cylinder = πr^2h

V of Cylinder = (2)^2 x 10 x π

V of Cylinder = 40π

V of Cone = πr^2(h/3)

V of Cone = π x (2)^2 x 3/3

V of Cone = π x 4 x 1

V of Cone = 4π

Total V = 40π + 4π

Total V = 138.23 ft³

4. A discount of 15% is allowed on an article. If a customer received N600.00, find the actual amount paid on the article.​

Answers

the man has #112,500 left as disposable income after paying taxes.

the actual amount paid on the article after the 15% discount is N600.00.

How to calculate the disposable income?

To calculate the disposable income of the man, we first need to determine his taxable income.

Taxable income = Annual income - Tax-free pay

Taxable income = #140,000 - #30,000 = #110,000

Next, we need to calculate the tax he has to pay on his taxable income.

Tax = Tax rate x Taxable income

Note that the tax rate is given in kobo, so we need to convert it to naira.

1 naira = 100 kobo, so 25 kobo = 0.25 naira

Tax = 0.25 x #110,000 = #27,500

Finally, we can calculate the disposable income by subtracting the tax from the annual income.

Disposable income = Annual income - Tax

Disposable income = #140,000 - #27,500 = #112,500

Therefore, the man has #112,500 left as disposable income after paying taxes.

4.If the discount allowed on an article is 15%, it means that the customer will pay only 85% of the original price of the article after the discount is applied.

Let the original price of the article be P.

Then, the amount paid by the customer after the 15% discount is 85% of the original price:

Amount paid = 0.85P

We know that the customer received N600.00.

So, we can set up an equation:

0.85P = N600.00

Solving for P, we get:

P = N600.00 / 0.85

P = N705.88 (rounded to two decimal places)

Therefore, the actual amount paid on the article after the 15% discount is N600.00.

Simulations may be used to find experimental probability. A simulation is a representation or model used to show outcomes of multiple trials of an experiment. For example, you could model 50 coin flips by assigning a 1 to heads and a 2 to tails, then using a random number generator to generate 50 outputs of the numbers 1 and 2. You may also simulate draws of a number by using a spinner, where the numbers on the spinner directly represent the numbers to be randomly drawn.

The concept of probability can be applied to either individual events or relationships between them, including intersection and union, in the field of accounting. Any event's probability value could be between 0 and 1 (or 0% and 100%).

The probability value represents the likelihood that a specific event or outcome will occur given a list of all conceivable events or outcomes. It is possible to express the probability value as a fraction or percentage. Also, depending on how an event is related to other events, the probability of an occurrence may be described in terms both independent or conditional probability.

Given data:

Answers

if you could fly like a bird, your trip would be approximately 3.9 miles shorter than the route you currently have to take (9 - 5.1 = 3.9).

If you were able to fly like a bird, you could take a direct path from your house to the grocery store, which would be shorter than the route you currently have to take.

By looking at the given directions, we can see that you have to travel a total of 1+1+5+2=9 blocks, with each block being a mile long, so your total distance traveled is 9 miles.

If you could fly like a bird, you could take a straight-line path from your house to the grocery store, which would be the hypotenuse of a right triangle with sides of 1 block and 5 blocks. Using the Pythagorean theorem, we can calculate that the distance of the hypotenuse would be the square root of[tex](1^2 + 5^2)[/tex] = square root of 26, which is approximately 5.

Find the lateral area of the pyramid

Answers

Answer:

The lateral surface area of the given square-based pyramid is 74 in².

Step-by-step explanation:

The lateral surface area of a three-dimensional object is the total surface area excluding the area of the base(s), so the total area of the "sides".

Therefore, the lateral surface area of a square-based pyramid is the sum of the area of the four triangular sides.

The area of a triangle is half the product of its base and height.

Therefore, the formula for the lateral surface area (L.S.A.) of a square-based pyramid is:

[tex]\boxed{\begin{minipage}{6 cm}\underline{L.S.A. of a square-based pyramid}\\\\$\sf L.S.A.= 2 \cdot s \cdot \ell$\\\\where:\\ \phantom{ww}$\bullet$ $s$ is the base length. \\ \phantom{ww}$\bullet$ $\ell$ is the slant height.\\\end{minipage}}[/tex]

From inspection of the given diagram:

[tex]\ell = \sf 7.4\;in[/tex][tex]s=\sf 5\;in[/tex]

Substitute the given values into the formula to calculate the L.S.A. of the given square-based pyramid:

[tex]\begin{aligned}\implies \sf L.S.A.&=\sf 2 \cdot 5 \; in \cdot 7.4 \; in\\&=\sf 10 \; in \cdot 7.4 \; in\\&=\sf 74 \; in^2\end{aligned}[/tex]

Therefore, the lateral surface area is 74 in².

The lateral area of the pyramid is approximately 74square inches.

What defines a pyramid's horizontal side?

The triangular faces of the pyramid that converge at the apex are known as the lateral faces. These are the four triangles that encircle the square base in the provided net. As a result, the entire area of the four triangles makes up the pyramid's lateral surface area.

According to the given information:To find the lateral area of a pyramid, we need to find the sum of the areas of all the triangular faces except for the base. The lateral area formula for a pyramid is given by:Lateral area = 0.5 × Perimeter of base × Slant height where the slant height is the height of each triangular face.

First, let's find the perimeter of the base. Since the base is a square with a side length of 5.1 inches, its perimeter is:

Perimeter of base = 4 × Side length = 4 × 5.1 in = 20.4

In Next,

let's find the slant height. We can use the Pythagorean theorem to find the slant height of each triangular face.

The slant height is the hypotenuse of a right triangle with one leg equal to half the base length (since the base is a square) and the other leg equal to the height of the pyramid.

Half the base length = 5.1 in / 2 = 2.55

In Using the Pythagorean theorem, we get:Slant height = √(2.55² + 7²) ≈ 7.45 In Finally,

we can use the lateral area formula to find the lateral area of the pyramid:

Lateral area = 0.5 × Perimeter of base × Slant height= 0.5 × 20.4 in × 7.45 in≈ 76.02 in²

Therefore, the lateral area of the pyramid is approximately 76.02 square inches. Which is near to 74

suppose you are conducting a hypothesis test to determine if a new marketing campaign increases sales for a particular product. what are the two types of errors you might make in conducting this test? (select all that apply)

Answers

The two types of errors you might make in conducting hypothesis test is type I error occurs when we conclude that the new marketing campaign does not increase sales when it actually does, This would lead to missed opportunities for increased sales and revenue for the company. Type II error occurs when we conclude that the new marketing campaign does not increase sales when it actually does, This would lead to missed opportunities for increased sales and revenue for the company. So, the correct option is A) and D).

Type I error is also known as a "false positive" error, where we reject the null hypothesis (i.e., conclude that the marketing campaign does increase sales) when it is actually false (i.e., the campaign does not have an effect on sales). This would lead to missed opportunities for increased sales and revenue for the company.

Type II error is also known as a "false negative" error, where we fail to reject the null hypothesis (i.e., conclude that the marketing campaign does not increase sales) when it is actually false (i.e., the campaign does have an effect on sales). This would also lead to missed opportunities for increased sales and revenue for the company.

Therefore, it is important to choose an appropriate significance level (alpha) and calculate the power of the test to minimize the risk of both types of errors in a hypothesis test. The correct answers are (A) and (D).

Roven bought 1/3kg of surkey ham. Chisa bought 2/9kg less barkey
ham thon Raven, How many kilograms of turkey hom did they
buy together!

Answers

Raven bought 1/3 kg of turkey ham, and Chisa bought 2/9 kg less. The total amount of turkey ham they bought together is 1/3 + 1/9 = 3/9 + 1/9 = 4/9 kg. Together, they bought a total of 4/9 kg of turkey ham.

What is fraction?

A fraction is a mathematical symbol that represents a portion of a whole or a component of a number. It is made up of two numbers divided by a horizontal line, with the number above the line (numerator) indicating the portion under consideration and the number below the line (denominator) indicating the entire or the total number of equal parts in the whole.

How many kilograms of turkey ham did they buy together?

From the given information, we know that Raven bought 1/3 kg of turkey ham, and Chisa bought 2/9 kg less than Raven. This means that Chisa bought:

1/3 kg - 2/9 kg = 3/9 kg - 2/9 kg = 1/9 kg

Now we can find the total amount of turkey ham they bought together by adding Raven's purchase and Chisa's purchase:

1/3 kg + 1/9 kg = 3/9 kg + 1/9 kg = 4/9 kg

Therefore, Raven and Chisa bought a total of 4/9 kg of turkey ham together.

The graph of the quadratic function is plotted, in which Vertex (h,k) = (-4,3).

Explain about the quadratic function:

In mathematics, a quadratic equation is one with degree 2, which means that its maximum exponent is 2. A quadratic has the formula y = ax2 + bx + c, where a, b, and c are all numbers and a cannot be zero.

Given quadratic function:

y = (x+4)²+3

Now, the equation in vertex form is:

y = a(x - h)² + k

(h,k) are the vertex.

On comparing:

a = 1, h = -4, and k = 3

Vertex (h,k) = (-4,3)

Decide on a number of points along the parabola, making sure to get points on each side of the parabola and replacing x with both positive and negative numbers.

The ideal mirror image is: y = (x+4)²+3

x = 0, y = 19

x = 1, y = 28

x = 2, y = 39

x = -4, y = 3

Plot the vertex together with the points you choose. With the vertex serving as the minimum point, draw a parabola (curve) it through points.

Using the graph,

The 1st statement is true as we can see from the graph the runner starts at origin 0 and till it reaches the point (12,1) it grows steadily as the graph is steep and increasing as we move forward.

This 2nd statement is also true as we can see in the graph that the 2nd runner's graph is a lot steeper than the 1st runner & stops at a point (20,2).

Define graph?

An organised representation of the data is all that the graph is. It facilitates our understanding of the facts. Data is the term used to describe the numerical information obtained through observation.

In the first statement:

It says that the runner begins the race & runs at a steady pace for 1 minute.

This statement is true as we can see from the graph the runner starts at origin 0 and till it reaches the point (12,1) it grows steadily as the graph is steep and increasing as we move forward.

Now in the 2nd statement it says, another runner runs from point (12,1) and runs at a steady but faster pace for 1 minute.

This statement is also true as we can see in the graph that the 2nd runner's graph is a lot steeper than the 1st runner.

So, the 2nd runner is going faster than the 1st and we can see that the 2nd runner stops at a point (20,2).

That shows the 2nd runner also ran for 1 minute.

When Ram was 16 years old, he deposited a certain sum of money in a bank at the rate of 10% p. a. Compounded annually. After his balance became 121 /700 times of the initial principal, he deposited 1/70 of the existing balance in the same account. After 1 year to this deposition, the bank changed it's policy to give interest at 20%p.a. simple interest. At the age of 24 years, Ram planned to start a business so, he withdrew all the money from his account. He found that the withdrawn amount was Rs. 359 less than thrice of the initial principal. Then,

1) Find the sum deposited by Ram at the age of 16 years.
2)The amount withdrawn from the bank was not enough so, he borrowed a loan of Rs. 1,10,000 from the bank and agreed to pay within 4 years, at a rate of 15% pa. compounded annually. He paid the interest of the first year at the end of the 1st year. He cleared his debt by paying equal installments in next year 2 years and 1 year. Find the total interest paid by him to the bank.
3) For how many years, he should have waited -to start the business so that he need not borrow an entra loan?​

Answers

Step-by-step explanation:

Let the principal deposited by Ram at the age of 16 be P.

After the balance became 121/700 times of the initial principal, we have:

(121/700)P = P(1 + 10/100)^n

where n is the number of years for which the amount is compounded annually.

Simplifying the above equation, we get:

n = log(121/700)/log(1.1)

After Ram deposited 1/70 of the existing balance, his new balance became:

(121/700)P + (1/70)[(121/700)P] = (121/700)P(1 + 1/10)

After 1 year of this deposit, the new balance became:

(121/700)P*(1 + 1/10)(1 + 20/100) = (121/700)P(11/10)*(6/5) = (363/350)P

Given that this amount is Rs. 359 less than thrice of the initial principal, we get:

(363/350)P = 3P - 359

=> P = Rs. 2450

Therefore, the sum deposited by Ram at the age of 16 years was Rs. 2450.

The loan amount borrowed by Ram from the bank is Rs. 1,10,000 at a rate of 15% p.a. compounded annually for 4 years. Let the interest paid by Ram at the end of the 1st year be I1.

The amount to be paid by Ram at the end of the 1st year = 1,10,000*(1 + 15/100) = Rs. 1,26,500

Out of this, Ram pays only the interest amount, i.e., I1.

The remaining amount to be paid by Ram after the 1st year = 1,26,500 - I1

This amount is to be paid in 3 years, at a rate of 15% p.a. compounded annually.

Let the equal installments to be paid by Ram for the next 3 years be X.

Therefore, we have:

X*(1 + 15/100)^3 + X*(1 + 15/100)^2 + X*(1 + 15/100) = 1,26,500 - I1

Solving the above equation, we get:

X = Rs. 36,285.47

Therefore, the total interest paid by Ram to the bank is:

I1 + 3X - 1,10,000 = I1 + 336,285.47 - 1,10,000 = Rs. 59,856.41

To avoid borrowing an extra loan, the withdrawn amount should be equal to or greater than the amount required to start the business.

The withdrawn amount is given by:

3P - 359 = 3*2450 - 359 = Rs. 6891

Therefore, Ram should have waited for the amount in his bank account to become Rs. 6891 or more, which would take n years, where:

(121/700)2450(1 + 10/100)^n >= 6891

Solving the above equation, we get:

n >= 4.52

Therefore, Ram should have waited for at least 5 years to start the business, to avoid borrowing an extra loan.

Step-by-step explanation:

Hello! I just did the quiz and this was the correct answer!

Solve for the unknown variable. Give all of the exact general solutions.

cosθ = sinθ

1 + sinθ = 2cos^2 (θ)

sin3θ = -1

Answers

Answer:

Solving for the unknown variable:

cosθ = sinθ

Dividing both sides by cosθ, we get:

tanθ = 1

Taking the inverse tangent of both sides, we get:

θ = π/4 + nπ, where n is an integer.

Therefore, the exact general solution is:

θ = π/4 + nπ, where n is an integer.

1 + sinθ = 2cos^2 (θ)

Using the identity cos^2 (θ) + sin^2 (θ) = 1, we can rewrite the equation as:

1 + sinθ = 2(1 - sin^2 (θ))

Expanding the right-hand side, we get:

1 + sinθ = 2 - 2sin^2 (θ)

Rearranging, we get:

2sin^2 (θ) + sinθ - 1 = 0

Using the quadratic formula, we get:

sinθ = (-1 ± √5)/4

Taking the inverse sine of both solutions, we get:

θ = arcsin [(-1 ± √5)/4] + 2nπ or π - arcsin [(-1 ± √5)/4] + 2nπ, where n is an integer.

Therefore, the exact general solution is:

θ = arcsin [(-1 ± √5)/4] + 2nπ or π - arcsin [(-1 ± √5)/4] + 2nπ, where n is an integer.

sin3θ = -1

Taking the inverse sine of both sides, we get:

3θ = (-1)^n (π/2) + 2nπ, where n is an integer.

Dividing both sides by 3, we get:

θ = (-1)^n (π/6) + (2nπ)/3, where n is an integer.

Therefore, the exact general solution is:

θ = (-1)^n (π/6) + (2nπ)/3, where n is an integer.

higher levels of confidence generally require: question 8 options: wider confidence intervals. narrower confidence intervals. a smaller standard error. unbiased estimates.

Answers

The correct answer is wider confidence intervals.

Why higher levels of confidence generally require wider confidence intervals?

In statistics, a confidence interval is a range of values that is likely to contain the true population parameter with a certain degree of confidence. The level of confidence is typically set at 90%, 95%, or 99%, and represents the percentage of intervals that would contain the true parameter if we were to repeat the sampling process many times.

Higher levels of confidence mean that we are more certain that the true parameter falls within the interval. However, achieving higher levels of confidence requires larger sample sizes or larger standard errors, which in turn leads to wider confidence intervals.

To understand this, consider the formula for a confidence interval:

CI = point estimate ± margin of error

The margin of error is a function of the sample size and the standard error. As the sample size increases or the standard error decreases, the margin of error decreases, which leads to a narrower confidence interval. Conversely, if we want to increase the level of confidence, we need to increase the margin of error, which requires either a larger sample size or a larger standard error, leading to wider confidence intervals.

Therefore, higher levels of confidence generally require wider confidence intervals, which means we are less precise in our estimate but more certain that the true parameter falls within the interval.

My Dear Sir: You ask me to put in writing the substance of what I verbally stated the other day, in your presence, to Governor Bramlette and Senator Dixon. It was about as follows: I am naturally anti-slavery. If slavery is not wrong nothing is wrong. I cannot remember when I did not so think and feel; and yet I have never understood that the Presidency conferred upon me an unrestricted right to act officially in this judgment and feeling. It was in the oath I took that I would to the best of my ability preserve, protect and defend the Constitution of the United States. I could not take the office without taking the oath. Nor was it in my view that I might take the oath to get power, and break the oath in using the power. I understood, too, that in ordinary civil administration this oath even forbade me to practically indulge my primary abstract judgment on the moral question of slavery. I had publicly declared this many times and in many ways; and I aver that, to this day I have done no official act in mere deference to my abstract judgment and feeling on slavery. I did understand, however, that my oath to preserve the Constitution to the best of my ability imposed upon me the duty of preserving, by every indispensable means, that government, that nation, of which that Constitution was the organic law. Was it possible to lose the nation, and yet preserve the Constitution? By general law, life and limb must be protected; yet often a limb must be amputated to save a life, but a life is never wisely given to save a limb. I felt that measures, otherwise unconstitutional, might become lawful by becoming indispensable to the preservation of the Constitution through the preservation of the nation. Right or wrong, I assumed this ground, and now avow it. I could not feel that to the best of my ability I had even tried to preserve the Constitution, if, to save slavery, or any minor matter, I should permit the wreck of government, country, and Constitution altogether. When, early in the war, General Fremont attempted military emancipation, I forbade it, because I did not then think it an indispensable necessity. When, a little later, General Cameron, then Secretary of War, suggested the arming of the blacks, I objected, because I did not yet think it an indispensable necessity. When, still later, General Hunter attempted military emancipation, I forbade it, because I did not yet think the indispensable necessity had come. When, in March and May and July, 1862, I made earnest and successive appeals to the Border States to favor compensated emancipation, I believed the indispensable necessity for military emancipation and arming the blacks would come, unless averted by that measure. They declined the proposition; and I was, in my best judgment, driven to the alternative of either surrendering the Union, and with it the Constitution, or of laying strong hand upon the colored element. I chose the latter. In choosing it, I hoped for greater gain than loss; but of this I was not entirely confident...Yours truly,A.
