The required sample size of the research is gotten to be; 324 students.

We are given;

Population standard deviation; σ = 2.3 minutes

Margin of error; E = 0.5 minutes

Significance level; α = 0.05

Since margin of error is 0.5, then we have a standard deviation of;

S = 2.3 - 0.5 = 1.8

Significance level is 0.05. Thus;

0.05 * 1.8 = 0.09

Now, this question has an earlier part whereby the data was from 1000 students. Thus;

The sample size is;

n = 0.09 * (1.8 * 2) * 100

The stress experimented by the bungee cord due to Max's weight is approximately 299.680 kilopascals.

Let suppose that the stress ([tex]\sigma[/tex]), in pascals, experimented by the bungee cord is entirely elastic and uniform. By Newton's Laws we know that the tension ([tex]T[/tex]), in newtons, experimented by the cord equals Max's weight. The stress on the bungee cord is axial and is described by following formula:

[tex]\sigma = \frac{m\cdot g}{\frac{\pi\cdot D^{2}}{4} }[/tex]   (1)

Where:

If we know that [tex]m = 15\,kg[/tex], [tex]g = 9.807\,\frac{m}{s^{2}}[/tex] and [tex]D = 0.025\,m[/tex], then the stress experimented by the bungee cord is:

[tex]\sigma = \frac{(15\,kg)\cdot \left(9.807\,\frac{m}{s^{2}} \right)}{\frac{\pi}{4}\cdot (0.025\,m)^{2} }[/tex]

[tex]\sigma \approx 299679.845\,Pa\, (299.680\,kPa)[/tex]

The number of liters of coffee that can be obtained per kilogram of coffee beans is; 5277.78 liters of coffee per kg of coffee beans

We are told that 1 pound of coffee yields 50 cups of coffee.

So we need to find the pounds of coffee beans required to produce 250 cups

Let's say we want to find the kg of coffee required to produce 200 cups of coffee. Then it is;

1 pound/50 cups * 4/4

= 4 pound/200 cups * kg/2.205 pound

= 0.009 kg/200 cups

Therefore 0.009 kilogram is used to produce 200 cups of coffee

Thus;

number of cups per kg = 200/0.009 cups per kg

Since 4 cups = 1 qt = 0.95 L

Then; 200/0.009 cups = ((200/0.009) * 0.95)/4

⇒ 5277.78 liters of coffee per kg of coffee beans

A line segment is regarded as a portion of a line that has two endpoints. The length of line segment MN is 18 units.

A line is known to be  kind of uni-dimensional shape that is said to range from  both directions that is said to never ends. A line segment is said to be a portion of the line and it is said to be the smallest distance between the two points that are said to be measured.

Note that if 2 chords intersect in a circle, what is gotten of their segments are said to be equal.

Therefore 9 * (x +1) = 15 * (x -1)

9x +9 = 15x -15

24 = 6x

x = 4

Therefore:

Line AD = 9 + x + 1

Line AD = 14

Line MN = 15 + x -1

Line MN = 18

So the correct option is 18 units.

The maximum values of a₁, a₂, a₃, a₄ and h to make the stack in equilibrium are; a₁_max = L/2; a₂_max = L/4; a₃_max = - L/6; a₄_max = -L/8; h = 25L/24

The system is in equilibrium and length of each brick = L

a) For brick 1;

Due to the fact that the center of gravity lies to the right of L/2,

Then we can say that the maximum value of a₁ = L/2

b) For brick 2;

Since the center of gravity lies to the right of L/2, then we can say that;

The maximum value of a₂ = ¹/₂a₁_max

Thus, the maximum value of a₂ = L/4

c) For brick 3;

Taking the moment of force, the maximum value of a₃ is;

a₃_max =  [(-¹/₂mL) + 2m(0)]/(2m +m)

a₃_max = - L/6

d) For the brick 4;

Taking the moment of force, the maximum value of a₄ is;

a₄ = [3(0) m + m(-L/2)]/(3m + m)

a₄_max = -L/8

e) The value of h = |a1| + |a2| +|a3| + |a4|

h = L/2 + L/4 + L/6 + L/8

The volume occupied by the given mol of helium gas at the given temperature and pressure is 91.6L.

Given the data in the question;

Volume of helium; [tex]V = \ ?[/tex]

The Ideal gas law or general gas equation emphasizes on the state or behavior of a hypothetical ideal gas. It states that  pressure multiplied by volume is equal to moles multiply by the universal gas constant multiply by temperature. It is expressed;

[tex]PV = nRT[/tex]

Where P is pressure, V is volume, n is the amount of substance, T is temperature and R is the ideal gas constant (  [tex]R = 0.08206Latm/molK[/tex] )

To determine the volume occupied by the helium gas, we substitute our values into the expression above.

[tex]PV = nRT\\\\V = \frac{nRT}{P} \\\\V = \frac{2.59mol\ *\ 0.08206Latm/molK\ *\ 356K}{0.826atm} \\\\V = \frac{75.6626L}{0.826}\\ \\V = 91.6L[/tex]
