Answer:

(s+2)^3

Step-by-step explanation:

I think this is referring to a square as a box, so the length of a jewelry box would be s. We learn that a shipping box is 2 inches longer, so s+2 = the length of the shipping box.

Volume = Length*Width*Height, but if square, all dimensions are the same, so s+2 to the power of 3 would be your answer.

Answer:

46 feet

Step-by-step explanation:

it is a 8-15-17 Pythagorean Triple (or you can use the Pythagorean theorem)

P=8+8+15+15=46

The perimeter of the rectangle with a length of 15 feet and has a diagonal that measures 17 feet is: A. 46 feet.

To find the perimeter of the rectangle, we need to know the width of the rectangle. Let's call the width of the rectangle W.

In a rectangle, the diagonal, length, and width are related by the Pythagorean theorem:

Diagonal² = Length² + Width²

In this case, the diagonal (D) is 17 feet, and the length (L) is 15 feet. So we have:

17² = 15² + W²

289 = 225 + W²

Now, let's solve for W:

W² = 289 - 225

W² = 64

W = √64

W = 8 feet

Now that we know the width is 8 feet, we can calculate the perimeter (P) of the rectangle:

Perimeter = 2 * (Length + Width)

= 2 * (15 + 8)

= 2 * 23

Perimeter = 46 feet

The area of the triangle is 94.9 square inches

For given question,

We have been given triangle RST has sides measuring 22 inches and 13 inches and a perimeter of 50 inches.

Let x be the third side of ΔRST

⇒ 22 + 13 + x = 50

⇒ x = 50 - 35

⇒ x = 15

Let s = sum of three sides of the triangle / 2

s = (22 + 13 + 15)/2

s = 25

Now using the formula for the area of the triangle,

A = √[s × (s-a) × (s-b) × (s-c)]

Let a = 22 inches, b = 13 inches, c = 15 inches

Substituting the values,

⇒ A = √[25 × (25 - 22) × (25 - 13) × (25 - 15)]

⇒ A = √(25 × 3 × 12 × 10)

⇒ A = √9000

⇒ A = 94.9 square inches

Therefore, the area of the triangle is 94.9 square inches

The area of  triangle rst which have sides 22 inches and 13 inches with perimeter 50 inches is 95 square inches.

We are given that the two sides of the triangle rst are 22 inches and 13 inches respectively. Also perimeter of the triangle rst is 50 inches.

We have to find the area of  triangle to the nearest square inches.

Let the third side of the triangle rst be x.

Hence,

22 + 13 + x = 50 inch

35 + x = 50 inch

x = 50 - 35
x = 15 inches

Hence, the third side of the triangle is 15 inches.

We will use the Heron's formula here to find the area of the triangle.

Heron's formula = \(\sqrt{s(s-a)(s-b)(s-c)}\)
Here,

s = Semi- perimeter

a, b, and c are sides of the triangle.

Hence,

\(s=\frac{50}{2} \\\\s=25 inches\)

a = 22 inches

b = 13 inches

c = 15 inches

Hence,

Area of the triangle rst = \(\sqrt{25(25-22)(25-13)(25-15)}\\\\ \sqrt{25(3)(12)(10)} =\sqrt{5*5*3*3*2*2*5*2}=5*3*2\sqrt{5*2}=30\sqrt{10}\)

We know that,

\(\sqrt{10}\) ≈ 3.162277
Hence,

\(\sqrt{10} * 30\) ≈ 94.86831 ≈ 95 square inches.

The closest answer is 80 cupcakes per minute, so the correct option is .8. The closest answer is 165 minutes, so the correct option is 165.

The throughput capacity of the icing stage can be calculated by dividing the number of cupcakes in a batch (100) by the time required to process each cupcake (1.25 minutes).

Throughput capacity = Number of cupcakes in a batch / Time to process each cupcake

Throughput capacity = 100 cupcakes / 1.25 minutes

Throughput capacity = 80 cupcakes per minute

The closest answer is 80 cupcakes per minute, so the correct option is .8.

The throughput time for a batch of cupcakes is the time required to process the entire batch, including the setup time.

Throughput time = Time for setup + (Number of cupcakes in a batch * Time to process each cupcake)

Throughput time = 40 minutes + (100 cupcakes * 1.25 minutes per cupcake)

Throughput time = 40 minutes + 125 minutes

Throughput time = 165 minutes

The closest answer is 165 minutes, so the correct option is 165.

a. It will take a dozen hens the same amount of time, a day and a half, to lay a dozen eggs.

The given information states that a hen and a half (1.5 hens) lay an egg and a half (1.5 eggs) in a day and a half. This implies that each hen lays 1 egg in 1 day.

Therefore, a dozen hens (12 hens) will lay a dozen eggs (12 eggs) in the same time frame, which is a day and a half.

b. It will take 9 days for 20 painters to paint 20 houses.

Given that 10 painters can paint 15 houses in 9 days, we can calculate the rate at which painters can paint houses.

This means that each painter can paint 1.5 houses in 9 days.

Therefore, to paint 20 houses, we need 20 painters, and the number of days required remains the same. So, 20 painters will also take 9 days to paint 20 houses.

c. It will take 14 days for 8 painters to paint 10 houses.

If 5 painters can paint 3 houses in 7 days, we can calculate the rate at which painters can paint houses.

This means that each painter can paint 0.6 houses in 7 days. Therefore, to paint 10 houses, we need 8 painters, and we can calculate the time required.

Hence, each painter can paint 0.6 houses in 7 days, so to paint 10 houses, 8 painters will take 14 days.

Answer: The answer is provided below

Step-by-step explanation:

A price markdown is a reduction that is deliberate when selling a product. From the question, we are informed that a video game that usually costs $30.65 is marked down 60%.

The find the new price of the video game, we have to subtract the amount reduced from the original price. The amount reduced is:

= 60% of $30.65

= 60/100 × $30.65

= 0.6 × $30.65

= $18.39

The new selling price = $30.65 - $18.39

= $12.26

The error that Kelvin made when he determined that the new price of the game would be $18.39 was that he didn't subtract the value from the original price of the video game.

This value represents the present worth below which the probability is 0.5, indicating a negative present worth.

To estimate the probability that the present worth is negative using the NORM.INV function in Excel,

we need to calculate the present worth of the project and then determine the corresponding probability using the normal distribution.

The present worth of the project can be calculated by finding the sum of the present values of the annual receipts over the 10-year period, minus the initial investment. The present value of each annual receipt can be calculated by discounting it back to the present using the minimum attractive rate of return (MARR).

Using the given information, the present value of the initial investment is $10,000. The present value of each annual receipt is calculated by dividing the expected return of $1,800 by \((1+MARR)^t\),

where t is the year. We then sum up these present values for each year.

We can use the NORM.INV function in Excel to estimate the probability of a negative present worth. The function requires the probability value, mean, and standard deviation as inputs.

Since we have a mean and standard deviation for the present worth,

we can calculate the corresponding probability of a negative present worth using NORM.INV.

This value represents the present worth below which the probability is 0.5. By using the NORM.INV function,

The standard deviation of the number of incorrect answers in an exam will be equal to 1.12.

If a student randomly guesses on an exam containing 5 true or false questions, the number of incorrect answers will follow a binomial distribution with n = 5 (the number of questions) and p = 0.5 (the probability of guessing incorrectly on each question). The standard deviation of a binomial distribution is given by the formula:

sd = √(np(1-p))

Plugging in the values n = 5 and p = 0.5, we get:

sd = √(50.5(1-0.5)) = √(50.50.5) = √(1.25) = 1.12

Let's call the time it takes the fair maiden to sew the border of the tapestry "t". So, her sister can sew the border in t/2 hours.

Working together, they can sew the border in t + t/2 = 1.5t hours.

Since we know the fair maiden can sew the border in 6 hours, we can substitute this into the equation to find t:

6 + 6/2 = 1.5t

Simplifying the right side of the equation:

6 + 3 = 1.5t

9 = 1.5t

Dividing both sides of the equation by 1.5:

t = 6

So the fair maiden can sew the border in 6 hours and her sister can sew the border in 6/2 = 3 hours.

To get an explicit value for this convergent series is not straightforward and may not be possible using elementary methods. Therefore, I can't provide you with the exact value if convergent.

To determine whether the series ∑n=1[infinity] 1/n(n+5) converges or not, we can use the comparison test. The comparison test states that if 0 ≤ a_n ≤ b_n for all n and the series ∑b_n converges, then the series ∑a_n also converges. Conversely, if the series ∑b_n diverges, then the series ∑a_n also diverges.
Your series is: ∑n=1[infinity] 1/n(n+5)
Let's compare it with the series: ∑n=1[infinity] 1/n^2
First, note that 0 ≤ 1/n(n+5) ≤ 1/n^2 for all n. Since the series ∑n=1[infinity] 1/n^2 is a p-series with p=2, which is greater than 1, it converges. Therefore, by the comparison test, the series ∑n=1[infinity] 1/n(n+5) also converges.

We are 95% confident that the proportion of American voters who favor congressional term limits is 64 percent with a difference of 3% for small sample size.

Step-by-step explanation:

95 % confidence means that we are 95 % confident that the the proportion of American voters who favor congressional term limits is 64 percent.

95 % confidence  means that of all the sample about 95 %  values are within in the given range.

And only 5% sample are not included in the given parameter.

Margin of error is the amount of miscalculation or difference in change of circumstances from the obtained data.

3% margin of error usually occurs when the data size is small.

As the data size increases the margin of error decreases.

So this statement tells us that we are 95% confident that the proportion of American voters who favor congressional term limits is 64 percent with a difference of 3% for small sample size.

Margin of error= z *σ/√n→

This indicates that as the sample size decreases the margin of error increases and vice versa.

A common everyday counting unit that is used to mean 12 of an object is a Dozen

Dozen is derived from the Old French word "douzaine" which means twelve each. In most situations, a dozen is used to refer to a group of twelve items. The term dozen is also used in informal situations to refer to a very large number of objects. For example, one might say "I have dozens of friends!" to mean that they have a lot of friends.

Dozen is a useful term when counting items. It allows for large numbers to be easily broken down into manageable groups. For example, if you have 120 pencils, you could easily count them by saying that you have 10 dozen pencils. It can also be useful when talking about fractions. For example, instead of saying "one and a half of an item," one could say "one and a half dozen of an item."

The probability that the plant will die when you're on vacation is 0.645 or 0.726 (rounded to three decimal places).

The probability that the plant will die when you're on vacation is 0.726. Here's how to get it:

Given that without water, the plant will die with probability 0.85, and with water, it will die with probability 0.6. Then, the probability that the plant will survive is:

1 - probability of dying without water - probability of dying with water= 1 - 0.85 - 0.6= -0.45 (Not possible since probability cannot be negative)

Thus, the probability that the plant will die is 0.45. Also, given that you are 82% certain that the neighbor will remember to water the plant, the probability that they will forget to water it is 1 - 0.82= 0.18.Then, the probability that the plant will die if the neighbor forgets to water it is 0.85, and the probability that it will die if the neighbor waters it is 0.6.

Using the law of total probability, the probability that the plant will die is:

P(Die) = P(Die | Water) P(Water) + P(Die | No water) P(No water)

Now substituting in the given values:

P(Die) = 0.6 × 0.82 + 0.85 × 0.18= 0.492 + 0.153= 0.645

Thus, the probability that the plant will die when you're on vacation is 0.645 or 0.726 (rounded to three decimal places).

The probability that the sample mean will be greater than 405 can be determined using the Central Limit Theorem. Assuming the population follows a normal distribution, we can calculate the probability using the standard deviation of the population and the sample size.

According to the Central Limit Theorem, when the sample size is large enough, the distribution of sample means will approach a normal distribution, regardless of the shape of the population distribution. In this case, the population mean is 400 and the standard deviation is 25.

To calculate the probability that the sample mean will be greater than 405, we need to convert the sample mean to a standard score (z-score) by subtracting the population mean and dividing by the standard deviation divided by the square root of the sample size.

z = (sample mean - population mean) / (standard deviation / sqrt(sample size))

= (405 - 400) / (25/\(\sqrt{100\))

= 5 / (25 / 10)

= 5 / 2

= 2.5

We can then use a standard normal distribution table or a statistical software to find the area under the curve to the right of the z-score 2.5. This area represents the probability that the sample mean will be greater than 405.

n the given problem, we have an implicit equation ln(x+y+z) = x+2y+3z that defines z as a function of x and y. We are given the values dy = (-1, 5, -3).

To find the derivative dy/dx, we can use the total derivative formula and apply it to the implicit equation. The total derivative is given by dy/dx = - (∂F/∂x)/(∂F/∂y), where F = ln(x+y+z) - x - 2y - 3z.

Differentiating F partially with respect to x and y, we have (∂F/∂x) = 1/(x+y+z) - 1 and (∂F/∂y) = 1/(x+y+z) - 2.

Plugging in the given values of dy = (-1, 5, -3), we can calculate dy/dx = - (∂F/∂x)/(∂F/∂y) = -(-1)/(5-2) = 1/3.

Therefore, the derivative dy/dx is equal to 1/3 based on the given information. It's important to note that this calculation assumes that the partial derivatives (∂F/∂x) and (∂F/∂y) are not zero at the given point (z.y.a).
