Step-by-step explanation:

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

To find when the daily ticket sales will peak, we need to find the maximum value of the quadratic equation [tex]N &= -0.3x^2+9x+13[/tex].

How to calculate no. of ticket solds and peak ticket sales?

Part 1:

The maximum value of a quadratic equation of the form [tex]y &= ax^2 + bx + c[/tex] occurs at [tex]x = \frac{-b}{2a}[/tex]. So in our case, the peak day will be at:

[tex]x &= \frac{-9}{2(-0.3)} = 15[/tex]

Therefore, the peak will be reached 15 days after the concert was first announced.

Part 2:

To find the number of tickets sold on that day, we substitute x=15 into the equation [tex]N &= -0.3x^2+9x+13[/tex]:

[tex]N &= -0.3(15)^2 + 9(15) + 13 = 67[/tex]

So the number of tickets sold on the day of the peak will be 67.

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))

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.

The probability of 12 power failures occurring in a semester is approximately 0.065 or 6.5%.

To calculate the probability of 12 power failures occurring in a semester, we need to use the Poisson distribution, which models the number of events that occur in a fixed interval of time or space.

The Poisson distribution is appropriate when the events occur randomly and independently, and the rate of occurrence is constant.

The Poisson distribution has a single parameter, lambda (λ), which represents the mean and variance of the distribution. In this case, λ = 2 power failures per month * 6 months in a semester = 12 power failures per semester.

Using the Poisson probability mass function, we can calculate the probability of exactly 12 power failures in a semester:

P(X = 12) = (e^(-λ) * λ^12) / 12!

= (e^(-12) * 12^12) / 12!

≈ 0.065

This means that in a large number of semesters, we would expect to observe 12 power failures in about 6.5% of them.

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

The length of the boundary wall that needs to be raised to enclose the entire football stadium is 420 + 40 = 460 meters.

To determine the length of the boundary wall that needs to be raised, we need to know which part of the stadium the wall will enclose.

If the wall is to be raised along the length of the stadium (i.e., the longer side), then the length of the wall will be equal to the length of the stadium, which is 125 meters.

If the wall is to be raised along the width of the stadium (i.e., the shorter side), then the length of the wall will be equal to the width of the stadium, which is 85 meters.

If the wall is to enclose the entire stadium, then we need to find the perimeter of the stadium and add the length of the wall that will enclose the remaining side.

Perimeter of the stadium = 2 x (length + width)

Perimeter of the stadium = 2 x (125 + 85) = 420 meters

To enclose the remaining side, we need to add a wall of length 125 - 85 = 40 meters.

Therefore, the length of the boundary wall that needs to be raised to enclose the entire football stadium is 420 + 40 = 460 meters.

Answer:21 tree cards

Step-by-step explanation:

The correct answer is 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.

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.

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.

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)

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.

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:

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

V= 1π · 6² · 14 / 3

V= 1π · 2²· 3² · 14 / 3

V= 2² · 14 · 3π

V= 2² · 14 · 3π

V= 2² · 42π

V= 4 · 42π

V= 168π

V=527.79

Hope this helps =D

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.

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.

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.

There are 1008 different combinations of three chocolates that they can choose.

What is a combination?

Combination is a way of selecting objects from a larger set, where the order of the selected objects does not matter.

There are three separate choices to be made, so we need to multiply the number of choices for each step.

First, the daughter chooses one of the 8 milk chocolates. She has 8 options.

Next, the son chooses one of the 9 plain chocolates. He has 9 options.

Finally, Mrs. Sweet chooses one of the remaining 14 chocolates (8 milk and 9 plain chocolates have already been chosen). She has 14 options.

To find the total number of combinations, we multiply the number of choices for each step:

8 x 9 x 14 = 1008

Therefore, there are 1008 different combinations of three chocolates that they can choose.

Gabrielle and Leslie are approximately 9.2 meters apart, rounded to the nearest tenth, given that Mrs. Kelley is standing 6 meters in front of Gabrielle and Leslie and Mrs. Kelley and Leslie are 7 meters apart.

Where M represents Mrs. Kelley, G represents Gabrielle, and L represents Leslie.

We can see that a right triangle is formed by Gabrielle, Mrs. Kelley, and the distance between Gabrielle and Leslie. We can use the Pythagorean theorem to find the missing side:

[tex]c^2 = a^2 + b^2[/tex]

where c is the distance between Gabrielle and Leslie, a is 6 meters (the distance between Mrs. Kelley and Gabrielle), and b is the distance between Mrs. Kelley and Leslie (which is equal to 7 meters).

Substituting the values, we get:

[tex]c^2 = 6^2 + 7^2[/tex]

[tex]c^2[/tex] = 36 + 49

[tex]c^2[/tex] = 85

Taking the square root of both sides, we get:

c ≈ 9.2

Therefore, Gabrielle and Leslie are approximately 9.2 meters apart, rounded to the nearest tenth.

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.
