The equation for money collected m for h boxes of chocolate bars sold is m = 30h.

We are given that the band is selling every bar of chocolate for $1.50

Now, they have boxes of chocolate, with every box containing 20 bars of chocolate in them.

Hence if we are going to calculate the amount of money collected on selling one box it will be

20 X $1.5

= $30

We need to find the equation for the amount of money collected based on the number of boxes of chocolate bars sold.

We have been given that money collected should be represented b m while the number of chocolate boxes sold should be represented by h

Now we know that

Money collected = price per box X no.of boxes sold

we have already calculated the price per box hence we get

m = 30h

The expected value of the envelope is less than 100,000, Margaret should reject the offer and keep her envelope.

To determine whether Margaret should accept the offer of $X for her envelope, we need to compare the expected value of the envelope to the amount offered. Given that the envelope contains either $81,000 or $40 with equal probability, the expected value of the envelope is calculated as follows:
Expected value = (probability of $81,000) * $81,000 + (probability of $40) * $40
Expected value = (1/2) * $81,000 + (1/2) * $40
Expected value = $40,520 + $20
Expected value = $40,540

According to Margaret's utility function, v(m) = m, she values money linearly. Therefore, for her to accept the offer of $X for her envelope, X should be at least equal to the expected value of the envelope. In this case, X should be at least $40,540.

9 block rhombuses would create 3 hexagons.

In order to increase the total number by three, a hexagon can be divided into a minimum of three rhombuses, each of which can be further divided into four rhombuses. With n being a positive integer, the result is 3n. The top two hexagons in this image are each divided into 8 and 10 rhombuses. The total number of rhombuses that can fit in a hexagon is not limited to multiples of three, given that the total number of rhombuses dividing a hexagon can be raised by three by quartering a single component rhombus.

The volume of the helium-filled balloon at 0.855 atm and 10.0 °C will be approximately 42.81 L, calculated using the ideal gas law equation.

To compute this problem, we can use the ideal gas law, which states that PV = nRT, where P is the pressure, V is the volume, n is the number of moles, R is the gas constant, and T is the temperature in Kelvin.

First, we need to convert the initial temperature of 25 °C to Kelvin:

T1 = 25 + 273.15 = 298.15 K

Next, we can rearrange the ideal gas law equation to solve for V2:

V2 = (P1 * V1 * T2) / (P2 * T1)

We have:

P1 = 1.08 atm (initial pressure)

V1 = 50.0 L (initial volume)

P2 = 0.855 atm (final pressure)

T2 = 10.0 °C (final temperature)

Converting the final temperature to Kelvin:

T2 = 10 + 273.15 = 283.15 K

Substituting the values into the equation:

V2 = (1.08 * 50.0 * 283.15) / (0.855 * 298.15)

V2 ≈ 42.81 L

Therefore, the volume of the helium-filled balloon at 0.855 atm and 10.0 °C will be approximately 42.81 L.

The teacher has offered his students a(n): algorithm

What is algorithm?

A method which solve a puzzle or carry out a calculation is known as an algorithm. Algorithms are precise lists of instructions that, in either software or hardware-based routines, carry out predetermined operations step by step. In many facets of IT, algorithms are commonly utilized. An algorithm is typically a short process that resolves a recurring issue in mathematics and computer science. Automated systems heavily rely on algorithms, which are also utilised as guidelines for carrying out data processing. Pseudocode, flowcharts, control tables, and plain languages are all ways to express algorithms. Since they are more ambiguous, natural language expressions are uncommon. Algorithms that a computer executes are typically expressed in programming languages.

A high school physics teacher reassures his class that no matter how confusing this week's word problems appear,

An isosceles triangle is a triangle whose two sides are of equal length. Triangle ABC is an isosceles triangle because of AB= BC.

An isosceles triangle is a triangle whose two sides are of equal length while the third side is of different length.

For the triangle to be an isosceles triangle, we need to find the length of each side of the triangle. Therefore, the length will be,

\(AB = \sqrt{(-1-7)^2+(-8-(-2))^2} = \sqrt{(-8)^2+(-6)^2} = 10\)

\(BC = \sqrt{(5-(-1))^2+(0-(-8))^2} = \sqrt{(6)^2+(8)^2} = 10\)

\(AC = \sqrt{(5-7)^2+(0-(-2))^2} = \sqrt{(-2)^2+(2)^2} = 2\sqrt2\)

Since for a triangle to be an isosceles triangle, it is needed that the two sides of the triangle must be equal while the third side should have different lengths, and as in the given triangle the length of AB=BC. It is an isosceles triangle.

Hence, triangle ABC is an isosceles triangle because of AB= BC.

Answer:

3 layers

Step-by-step explanation:

Given

\(L = 1cm\) --- side length of the cube

Each layer = 2 * 2 cube

\(Volume = 24cm^3\)

Required

Determine the number of layers

First, we calculate the volume of each layer:

The length of the layer is:

\(Length = 2 * L\)

\(Length = 2 * 1cm\)

\(Length = 2cm\)

Next, we calculate the volume of each layer:

\(Volume = Length^3\)

\(Volume = (2cm)^3\)

\(Volume = 8cm^3\)

The number of layer is calculated by dividing the volume of the tower by the volume of each layer

\(Layers = \frac{24cm^3}{8cm^3}\)

\(Layers = 3\)

520 divided by 40= 13

The pebbles cover an area of 147 sq ft. We can use the Pythagorean theorem to find the solution.

Let's call the length of the third side of the triangle "x".

Since the two triangles are equal in size, and they share two sides with the square, we can use the Pythagorean theorem to find x.

a² + b² = c²

7² + 7² = c²

49 + 49 = c²

98 = c²

c = sqrt(98)

c = 7sqrt(2)

So each triangle has a base of 7ft and a height of 7sqrt(2)ft.

Area of each triangle = (base * height) / 2 = (7 * 7sqrt(2)) / 2 = 24.5 sq ft

Since there are two triangles, the total area of the grass is 24.5 sq ft * 2 = 49 sq ft

The square has an area of 14ft * 14ft = 196 sq ft

The pebbles cover an area of 196 sq ft - 49 sq ft = 147 sq ft.

On average, the value expected for the t-statistic when the null hypothesis is B. 0.

When the null hypothesis is true, the expected value of the t-statistic is zero (0). This is because the t-statistic is calculated by taking the difference between the sample mean and the hypothesized population mean (under the null hypothesis), and dividing it by the standard error.

If the null hypothesis is true, there should be no difference between the sample mean and the hypothesized population mean, resulting in a t-statistic of zero on average. Therefore, the correct answer is option B, "O", which represents zero.
