what is the probability of randomly selecting three americans from a group of 8 italians and 5 americans? enter your answer as a fraction.
The overall probability of selecting three Americans is:5/13 * 4/12 * 3/11 = 5/143 Answer: 5/143
Probability of selecting first American = number of Americans / total number of people= 5 / (5 + 8)= 5 / 13
Probability of selecting the second American = number of Americans / total number of remaining people after selecting the first American
= 4 / 12 (as there will be 12 people remaining after selecting the first American, which includes 4 Americans and 8 Italians)
Probability of selecting the third American = number of Americans / total number of remaining people after selecting the first and second American
= 3 / 11 (as there will be 11 people remaining after selecting the first and second American, which includes 3 Americans and 8 Italians)
Therefore, the overall probability of selecting three Americans is:5/13 * 4/12 * 3/11 = 5/143 Answer: 5/143

Marissa's shape is classified as a scalene and obtuse triangle, considering it's concepts presented in this problem.
How to classify the triangle?The triangle has three sides of unequal length, as the opposite angle measures are different, hence it is classified as an scalene triangle.
(it would be equilateral if all had the same length, and isosceles if two sides have the same length).
The triangle has one angle larger than 90º, hence it is classified as an obtuse triangle.
(acute with no angles of 90º or greater, right with one angle of exactly 90º).

Answer:
z=3
Step-by-step explanation:
6z-30=-12
6z=18
z=3
Answer:
z = 3
Step-by-step explanation:
When solving for z, we have to isolate the variable (z). We do this by adding, subtracting, multiplying, and dividing. When we do one of them, we must do it for both sides to "keep it even".
We can start by seeing that the 3 on the left is not in the parentheses meaning multiplication. So, to get z alone, the first step is dividing both sides by 3.
3(2z-10) = -12
/3 /3
2z-10 = -4
The next step to getting z alone is adding 10 to both sides.
2z-10 = -4
+10 +10
2z = 6
For the final step in getting z alone, we can see that on the left sides, it says 2z, meaning 2 times z. To undo this and get it alone, we can divide both sides by 2
2z = 6
/2 /2
z = 3
Therefore, the answer is z = 3
Why is i squared equal to 1?

where p is pressure, V

is molar volume, T is temperature, R is the perfect gas constant, and b is a gas dependent coefficient. Assuming that there were gases that obeyed these equations of state, answer the following: PART A Do either of these equations of state possess a critical temperature? PART B Would it be possible to liquefy a gas that had EOS A as the equation of state? Explain. PART C Would it be possible to liquefy a gas that had EOS B as the equation of state? Explain.
PART A: Neither EOS A nor EOS B possess a critical temperature. PART B: Liquefaction is possible for a gas described by EOS A due to its pressure-dependent term. PART C: Liquefaction is not possible for a gas described by EOS B because of its constant positive term (Vm – b).
PART A:
To determine if either of the equations of state possesses a critical temperature, we need to check if they exhibit a phase transition from gas to liquid at a specific temperature. In thermodynamics, the critical temperature is the temperature above which a substance cannot exist in the liquid phase, regardless of the pressure applied.
Equation of State A: pV^m = RT(1 + Vm * b)
In this equation, there is no specific term or condition that indicates a critical temperature. Therefore, EOS A does not possess a critical temperature.
Equation of State B: p(Vm – b) = RT
Similarly, there is no term or condition that suggests a critical temperature in EOS B. Thus, EOS B also does not possess a critical temperature.
PART B:
For a gas described by EOS A, liquefaction may be possible. To liquefy a gas, we need to decrease its temperature and increase the pressure. The equation of state A, pV^m = RT(1 + Vm * b), allows for the possibility of liquefaction because as the pressure increases, the term (1 + Vm * b) becomes larger. By sufficiently decreasing the temperature and increasing the pressure, it is possible to reach conditions where the gas would condense into a liquid state.
PART C:
Liquefaction would not be possible for a gas described by EOS B. The equation of state B, p(Vm – b) = RT, does not allow for the possibility of liquefaction because the term (Vm – b) is always positive. Regardless of how much we decrease the temperature or increase the pressure, the gas will not condense into a liquid state according to EOS B.

if a single gold atom has a diameter of 2.9×10−10 m, how many atoms thick was rutherford's foil?
The foil was approximately 3.4 × 10⁷ atoms thick.
Rutherford's foil was made of gold and was used in his famous alpha particle scattering experiment. The thickness of the foil can be calculated by dividing its actual thickness by the diameter of a single gold atom.
Let's assume that the gold atoms in the foil are arranged in a simple cubic lattice. In this case, the actual thickness of the foil can be calculated as the number of gold atoms along one edge of the cube times the diameter of a single gold atom:
actual thickness = number of atoms × diameter of a single atom
To calculate the number of gold atoms, we need to know the density of gold and the mass of the foil. Let's assume that the density of gold is 19.3 g/cm³ and the mass of the foil is 0.6 mg = 6.0 × 10⁻⁷ kg.
The volume of the foil can be calculated as its mass divided by its density:
volume = mass / density = 6.0 × 10⁻⁷ kg / (19.3 × 10³ kg/m³) = 3.11 × 10⁻¹⁰ m³
The volume of the foil is also equal to the product of its actual thickness, the area of one face of the cube (which is the square of the number of atoms along one edge), and the volume of a single gold atom (which is (4/3)πr³, where r is the radius of the atom):
volume = actual thickness × (number of atoms)² × (4/3)πr³
Substituting the diameter of a single gold atom (2.9 × 10⁻¹⁰ m) for 2r, we get:
volume = actual thickness × (number of atoms)² × (4/3)π(1.45 × 10⁻¹⁰ m)³
Equating the two expressions for the volume of the foil, we get:
actual thickness × (number of atoms)² × (4/3)π(1.45 × 10⁻¹⁰ m)³ = 3.11 × 10⁻¹⁰ m³
Solving for the number of atoms, we get:
number of atoms = √(3.11 × 10⁻¹⁰ m³ / [(4/3)π(1.45 × 10⁻¹⁰ m)³]) ≈ 3.4 × 10⁷
So the foil was approximately 3.4 × 10⁷ atoms thick.

What would be the slope of a line that is perpendicular to the linear equation y = (-2/3)x +5?
Answer: The slope of a perpendicular line will be m = 3/2. To find the perpendicular gradient take the negative inverse of the original gradient.
Step-by-step explanation:
The slope of a perpendicular line will be m = 3/2. To find the perpendicular gradient take the negative inverse of the original gradient.
By 'negative inverse' I mean change the sign and switch the numerator and denominator (the top and bottom of the fraction).
The original gradient there is m = - 2/3. Remember the line equation: y = mx + c.
To gain the perpendicular gradient change the - to +, move the 3 to the top and the 2 to the bottom. Now m = + 3 / 2 = 3/2

QUESTION 15 Areej invested BD 14000 12 years ago, today this investment is worth BD 52600, based on this what annualized rate has Areej earned on this investment? O 11.66% O 2.75% 17.43% 8.91%
To calculate the annualized rate of return, we can use the formula for compound interest. The correct answer is 11.66%.
The formula for compound interest is given by: A = P(1 + r)^t, where A is the final amount, P is the principal amount, r is the annual interest rate, and t is the time in years.
In this case, the initial investment (P) is BD 14,000, the final amount (A) is BD 52,600, and the time (t) is 12 years. We need to solve for the annual interest rate (r).
\(BD 52,600 = BD 14,000(1 + r)^{12}\)
By rearranging the equation and solving for r, we find:
\((1 + r)^{12} = 52,600/14,000\)
Taking the twelfth root of both sides:
\(1 + r = (52,600/14,000)^{(1/12)}\\r = 0.1166 / 11.66 \%\)
Therefore, Areej has earned an annualized rate of approximately 11.66% on this investment.
