Using arithmetic operations, The total cost of six sheets will be:

$27.00 + ($9.00 x 4) = $63.00

If each sheet costs $18.00, then the cost of the first sheet will be $18.00, and the cost of the second sheet will be 50% of $18.00, or $9.00.

So, two sheets will cost the cost of the first sheet plus the cost of the second sheet, which is:

Using addition,

$18.00 + $9.00 = $27.00

For six sheets, we can use the same logic: the first two sheets will cost $27.00, and the next four sheets will be half off. So, the cost of the next four sheets will be 50% of $18.00, or $9.00 each.

Hence, the total cost of six sheets will be:

$27.00 + ($9.00 x 4) = $63.00

The p-value for this sample is approximately 0.004655 which is smaller than the significance level of 0.005. This means that we reject the null hypothesis and conclude that there is evidence to support the alternative hypothesis that the population proportions are not equal.

To test the hypothesis Hₐ : p₁ ≠ p₂ at a significance level of α = 0.005, we can use the two-sample z-test for proportions, where the test statistic is given by:

z = (p₁ - p₂) / sqrt{p(1-p)(1/n₁ + 1/n₂)}

where p = (x₁ + x₂) / (n₁ + n₂) is the pooled sample proportion, x₁ and x₂ are the number of successes in the two samples, n₁ and n₂ are the sample sizes for the two samples, and p₁ and p₂ are the sample proportions for the two samples.

Plugging in the given values, we have:

p₁ = 119/687 ≈ 0.1732

p₂ = 137/577 ≈ 0.2374

n₁ = 687

n₂ = 577

p = (119 + 137) / (687 + 577) ≈ 0.202

z = (0.1735 - 0.2376) / √{0.202 * (1 - 0.202) * (1/687 + 1/577)} ≈ -2.83

The test statistic for this sample is approximately -2.83

To find the p-value for this sample, we need to find the probability of observing a test statistic as extreme as -2.83, assuming that the null hypothesis is true. Since this is a two-tailed test, we need to find the area in the tails of the standard normal distribution that corresponds to a significance level of 0.005:

α/2 = 0.005/2 = 0.0025

Using a standard normal table or a calculator, we can find that the z-score corresponding to an area of 0.0025 in the left tail of the standard normal distribution is approximately -2.81. The z-score corresponding to an area of 0.0025 in the right tail is approximately 2.81.

The p-value for this sample is the sum of the areas in the tails beyond the test statistic:

p-value = P(Z ≤ -2.83) + P(Z ≥ 2.83)

P = 0.004655

Answer:

Let's start by finding out how many muffins were there in total before the ogre stole 20 of them. Let's call that number "x".

If 5/8 of them were left after the ogre stole 20, then 3/8 of them were taken.

So we can set up an equation:

x - 20 = 3/8x

To solve for x, we can start by multiplying both sides by 8 to get rid of the fraction:

8(x - 20) = 3x

8x - 160 = 3x

Now we can solve for x by subtracting 3x from both sides:

5x - 160 = 0

5x = 160

x = 32

So there were originally 32 muffins.

Now we can find out how many are left:

5/8 of 32 = 20

So there are 20 muffins left.

The percent discount being offered is 20%.

What is percentage ?

Percentage is a way of expressing a number as a fraction of 100. It is often denoted by the symbol %, which means "per cent" or "out of 100". Percentages are used to compare two quantities and express the relationship between them in terms of the fraction of one quantity that the other quantity represents.

To find the percent discount, we need to first calculate the amount of discount that is being offered. We can do this by subtracting the sale price from the original price:

Discount = Original Price - Sale Price

Discount = $79.95 - $63.96

Discount = $15.99

Next, we can calculate the percentage discount by dividing the discount by the original price and then multiplying by 100:

Percent Discount = (Discount / Original Price) x 100

Percent Discount = ($15.99 / $79.95) x 100

Percent Discount = 20%

Therefore, the percent discount being offered is 20%.

Answer:

the original price of each costume was $25, and the sale price was $(25-3.50) = $21.50.

Step-by-step explanation:

Let the original price of each costume be $x. The sale price of each costume will be $(x-3.50). Ms. Monroe ordered 24 costumes, so the cost of 24 costumes at the sale price will be:

24 × (x-3.50) = $24x - $84

Ms. Monroe paid $516 in all, so we can write:

24x - 84 = 516

Adding 84 to both sides, we get:

24x = 600

Dividing both sides by 24, we get:

x = 25

Therefore, the original price of each costume was $25, and the sale price was $(25-3.50) = $21.50.

Answer: so Ms.Monroe got $84 off her entire purchase

The two points with an x-coordinate of 2 and a distance of 5 from (-2, -4) are: (2, -4 + 2√13) and (2, -4 - 2√13)

What is distance formula?

Distance is a measurement of how far away two things or locations are, either numerically or occasionally qualitatively.

Distance formula: [tex]distance = \sqrt{((x2 - x1)^2 + (y2 - y1)^2)}[/tex]

We can solve this problem using the distance formula, which gives us the distance between two points in a plane:

[tex]distance = \sqrt{((x2 - x1)^2 + (y2 - y1)^2)}[/tex]

Let (x, y) be a point with an x-coordinate of 2. Then we can write the distance from (-2, -4) to (x, y) as:

[tex]distance = \sqrt{((x - (-2))^2 + (y - (-4))^2)}[/tex]

Simplifying this expression, we get:

[tex]distance = \sqrt{((x + 2)^2 + (y + 4)^2)}[/tex]

We know that the distance between (-2, -4) and (x, y) is 5. Therefore, we can write:

[tex]\sqrt{((x + 2)^2 + (y + 4)^2)} = 5[/tex]

Squaring both sides, we get:

[tex](x + 2)^2 + (y + 4)^2 = 25[/tex]

Expanding the left side, we get:

[tex]x^2 + 4x + 4 + y^2 + 8y + 16 = 25[/tex]

Simplifying this expression, we get:

[tex]x^2 + 4x + y^2 + 8y - 5 = 0[/tex]

To find all points with an x-coordinate of 2 that satisfy this equation, we can substitute x = 2 and simplify the resulting equation:

[tex]2^2 + 4(2) + y^2 + 8y - 5 = 0[/tex]

Simplifying this equation, we get:

[tex]y^2 + 8y + 3 = 0[/tex]

We can solve this quadratic equation using the quadratic formula:

y = (-b ± sqrt(b^2 - 4ac)) / 2a

where a = 1, b = 8, and c = 3.

Plugging in these values, we get:

y = (-8 ± sqrt(8^2 - 4(1)(3))) / 2(1)

Simplifying this expression, we get:

y = (-8 ± √52) / 2

y = (-8 ± 2√13) / 2

y = -4 ± √13

Therefore, the two points with an x-coordinate of 2 and a distance of 5 from (-2, -4) are: (2, -4 + 2√13) and (2, -4 - 2√13)

Answer:

When the ball hits the ground, its height will be 0 meters. Therefore, we need to solve the equation:

h(t) = 0

8t - 5t^2 + 4 = 0

We can solve this quadratic equation by factoring or by using the quadratic formula, but in this case, it's easier to use factoring:

(5t - 4)(t - 1) = 0

From this equation, we can see that either 5t - 4 = 0 or t - 1 = 0. Solving for t in each case, we get:

5t - 4 = 0 ==> t = 0.8 seconds

t - 1 = 0 ==> t = 1 second

Therefore, the ball will reach the ground after either 0.8 seconds or 1 second, depending on the initial height of the ball.

The area of a circle is (π) x (radius)^2.

Here, you are given the diameter.

To find the radius, divide the diameter by 2, which results in 4.

(π) x (4)^2

Now square the 4, which results in 16

3.14 x 16 = 50.24

50.24 would be the area of the circle not cut in half, so divide 50.54 by 2 to get half.

50.24/2 = 25.12

Answer:

Step-by-step explanation:

The area of Circle is [tex]\pi r^{2}[/tex]

So, the area of half circle is [tex]\frac{\pi r^{2} }{2}[/tex]

Diameter is given = 8cm

so radius will be 4 cm

[tex]A = \frac{\pi 4^{2} }{2} \\A = \frac{\pi 16}{2} \\A = 8\pi[/tex]

A = 8 × 3.14

It is estimated that producing an additional 500 lb of paper once 10 tons have been produced would cost approximately $95,000.

What is Algebraic expression ?

Algebraic expression can be defined as combination of variables and constants.

To estimate the cost of producing an additional 500 lb of paper, we need to first convert 500 lb to tons.

1 lb = 0.0005 tons

So, 500 lb = 0.25 tons

Now, we can use the marginal cost formula:

MC = C'(t)

where MC is the marginal cost and C'(t) is the derivative of the cost function with respect to t.

We are given that C'(10) = 380, which means that the marginal cost of producing the 10th ton of paper is $380,000.

To estimate the cost of producing an additional 500 lb of paper once 10 tons have been produced, we need to find the marginal cost at t = 10.

Therefore, the estimated cost of producing an additional 500 lb of paper is:

MC(10) ≈ C'(10) ≈ $380,000 per ton

0.25 tons x $380,000 per ton = $95,000

Hence, it is estimated that producing an additional 500 lb of paper once 10 tons have been produced would cost approximately $95,000.
