Answer:

A) 29men

B) 91cm

C) 13cm

Step-by-step explanation:

Men with waist of 85cm = 11

A.) Men with waist of more than 85cm = (total number of men - 11) = (40 - 11) = 29men

B.) median waist :

Median = (n) / 2

Where n = number of observations

Median = (40) / 2 = 40/2 = 20th

Taking the intersection of the 20th point on the x-axis,

Median waist = 91cm

C.) Interquartile range(IQR) = (Q3 - Q1)

Q3 = 3/4(n)

Q3 = 0.75 × 40 = 30

Q3 = 97cm

Q1 = 1/4(n)

Q1 = 0.25 × 40 = 10

The probability of hitting the black circle inside the target is approximately 0.0314.

The probability of hitting the white portion of the target is approximately 0.686.

Part A:

The black circle has a diameter of 2 units, which means it has a radius of 1 unit. The area of the circle is πr^2, which is π(1)^2 or π square units. The area of the white square is 10 x 10 or 100 square units.

The probability of hitting the black circle inside the target is the ratio of the area of the circle to the area of the square, which is π/100 or approximately 0.0314. This probability is closer to 0 because the circle is much smaller than the square, and the likelihood of hitting the exact center of the circle is low.

Part B:

The white portion of the target is the area of the square minus the area of the black circle, which is 100 - π square units.

The probability of hitting the white portion of the target is the ratio of the area of the white portion to the area of the square, which is (100-π)/100 or approximately 0.686.

This probability is closer to 1 because the white portion of the target is much larger than the black circle, and there are many possible areas of the square that could be hit.

The trapezoidal rule is a numerical integration method that frequently overestimates the real value of a function's definite integral.

The trapezoidal rule is a strategy for approximating the definite integral in calculus. The trapezoidal rule works by computing the area of the region under the graph of the function f(x) that is approximated as a trapezoid. The trapezoidal rule is commonly used to calculate the area under curves. This is achievable if the overall area is divided into smaller trapezoids rather than rectangles. The Trapezoidal Rule integration determines the area by approximating the area under a function's graph as a trapezoid. The midway rule uses rectangular areas to approximate the definite integral, whereas the trapezoidal rule uses trapezoidal approximations to approximate the definite integral. Simpson's approach works by first approximating the original function with piecewise quadratic functions.

The HHT is more likely to appear first with a probability of 2/3.

The probability is an estimation of the likelihood that an event will occur. It assesses the event's certainty.

The formula for probability is given as;

P(E) = Number of Favourable Outcomes/Number of total outcomes.

Now according to the given question;

Only the second and third flips in the sequence matter. We understand the first flip is an H, and we're not interested in sequences that begin with T.

Lets start with the given format;

H _ _

If we get an HH_, the game is over and HHT will surely win (regardless of the number of heads we get, the next T is an automatic win). If we get an HTT, the game is over.

If we get an HTH, the game is a tie, and we must restart it.

Thus,

P(HHT) = 1/2

P(HTT) = 1/4

P(Draw) = 1/4

P(HHT wins) = P(HHT) / [1-P(Draw)]

                     = (1/2) / (1-1/4)

P(HHT wins) = 2/3

Thus, the probability of occurrence of HHT has more chances with 2/3.

To determine the number of lawns Carlos and Jack need to mow in order to have enough money for the school trip, an inequality is established based on their current savings and the cost of the trip. The inequality is solved to find the minimum number of lawns they need to mow individually.  

Part A: To find the number of lawns each boy needs to mow individually, we can set up an inequality based on their current savings and the cost of the trip. Carlos has $42 and Jack has $51. Let's assume Carlos needs to mow 'x' lawns, and Jack needs to mow 'y' lawns. The inequality can be written as:

42 + 30x ≥ 156

51 + 30y ≥ 156

Solving these inequalities will give us the minimum number of lawns each boy needs to mow to have enough money for the trip.

Part B: Now, if Carlos and Jack want to earn an additional $75 each for spending money, they plan to work together mowing lawns. Let 'z' represent the number of lawns they mow together. The new inequality can be written as:

30z ≥ 75

To find the number of lawns they need to mow together to earn the extra money, we can solve this inequality. By solving the inequalities, you will obtain the specific values for 'x' and 'y' in Part A and 'z' in Part B, which represent the minimum number of lawns each boy needs to mow individually or together to have enough money for the trip and earn additional spending money.

The solution to the given differential equation 2xy(dy/dx) = y², with the initial condition y(2) = 3, is y = (27 * e⁽ˣ⁻²⁾\()^{1/4}\).

To solve the given differential equation

2xy(dy/dx) = y²

We will use separation of variables and integrate to find the solution.

Start with the given equation

2xy(dy/dx) = y²

Divide both sides by y²:

(2x/y) dy = dx

Integrate both sides:

∫(2x/y) dy = ∫dx

Integrating the left side requires a substitution. Let u = y², then du = 2y dy:

∫(2x/u) du = ∫dx

2∫(x/u) du = ∫dx

2 ln|u| = x + C

Replacing u with y²:

2 ln|y²| = x + C

Using the properties of logarithms:

ln|y⁴| = x + C

Exponentiating both sides:

|y⁴| = \(e^{x + C}\)

Since the absolute value is taken, we can remove it and incorporate the constant of integration

y⁴ = \(e^{x + C}\)

Simplifying, let A = \(e^C:\)

y^4 = A * eˣ

Taking the fourth root of both sides:

y = (A * eˣ\()^{1/4}\)

Now we can incorporate the initial condition y(2) = 3

3 = (A * e²\()^{1/4}\)

Cubing both sides:

27 = A * e²

Solving for A:

A = 27 / e²

Finally, substituting A back into the solution

y = ((27 / e²) * eˣ\()^{1/4}\)

Simplifying further

y = (27 *  e⁽ˣ⁻²⁾\()^{1/4}\)

Therefore, the solution to the given differential equation with the initial condition y(2) = 3 is

y = (27 * e⁽ˣ⁻²⁾\()^{1/4}\)

b) n=4, l=2 -> 4d subshell

c) n=2, l=0 -> 2s subshell

d) n=5, l=3 -> 5f subshell

In the electron configuration of an atom, each electron is described by a set of four quantum numbers, which includes the principal quantum number (n), the angular momentum quantum number (l), the magnetic quantum number (m), and the spin quantum number (s). The second quantum number (l) determines the shape of the subshell, which in turn influences the energy level and chemical behavior of the atom. The letter designation for each subshell is based on the value of the angular momentum quantum number (l): s (l=0), p (l=1), d (l=2), f (l=3), and so on. Therefore, for a given set of quantum numbers, we can determine the subshell designation by identifying the value of l.

The solutions to the equation −11x − 7 = \(-3x^2\), rounded to the nearest tenth, are x ≈ -1.1 and x ≈ 6.1.

An equation is a mathematical statement that shows that two expressions are equal. It is usually written as an expression on the left-hand side (LHS) and an expression on the right-hand side (RHS) separated by an equal sign (=).

The expressions on both sides of the equation can contain variables, constants, and mathematical operations such as addition, subtraction, multiplication, and division. The variables in an equation represent unknown values that can vary, while the constants are fixed values that do not change.

Equations are used to represent mathematical relationships or describe real-world situations. They can be used to solve problems, make predictions, and test hypotheses.

To solve an equation, one must find the value of the variable that makes the LHS equal to the RHS. This is done by performing mathematical operations on both sides of the equation to isolate the variable. The goal is to get the variable by itself on one side of the equation, with a specific value on the other side.

Equations can be simple or complex, linear or nonlinear, and can involve one or more variables. Examples of equations include:

2x + 5 = 13

y = \(3x^2\) - 2x + 7

4a + 2b - 3c = 10

Equations are used in many areas of mathematics and science, including physics, chemistry, and engineering, among others.

We are given the equation \(-11x - 7 = -3x^2\).

To solve for x, we can rearrange the equation into a quadratic form by bringing all terms to one side:

\(-3x^2 + 11x + 7\) = 0

We can solve this quadratic equation by using the quadratic formula:

x = (-b ± sqrt(\(b^2\) - 4ac)) / 2a

where a = -3, b = 11, and c = 7.

Substituting these values, we get:

x = (-11 ± sqrt(\(11^2\) - 4(-3)(7))) / 2(-3)

Simplifying inside the square root:

x = (-11 ± sqrt(121 + 84)) / (-6)

x = (-11 ± sqrt(205)) / (-6)

Using a calculator, we can approximate this to:

x ≈ -1.1 or x ≈ 6.1

Therefore, the solutions to the equation \(-11x - 7 = -3x^2\), rounded to the nearest tenth, are x ≈ -1.1 and x ≈ 6.1.

Step-by-step explanation:

One way to determine which factored expression is accurate is by asking the question: "Which two numbers multiply to 88, but add to 26?" If you are having difficulty using this method, you can always try the guess-and-check method with a multiple choice question. This way involves multiplying the terms inside one set of parentheses with the terms inside the other set of parentheses.

Step #1: Multiply the first terms

(n + 4)(n + 22) ----> n x n = n²

Step #2: Multiply the inside terms

(n + 4)(n + 22) -----> 4 x n = 4n

Step #3: Multiply the outside terms

(n + 4)(n + 22) -----> n x 22 = 22n

Step #4: Multiply the last terms

(n + 4)(n + 22) -----> 4 x 22 = 88

Step #5: Write the new expanded equation and simplify

(n + 4)(n + 22) -----> n² + 4n + 22n + 88 -----> n² + 26n + 88

Step-by-step explanation:

The final solution for f(x) is: f(x) = x^3 + 3x^4 + 2. We can use integration to find f(x) given the second derivative f ''(x) = 6x + 36x^2 and the initial conditions f(0) = 2 and f(1) = 13.

First, we integrate f ''(x) once to obtain the first derivative f'(x):

f'(x) = ∫(6x + 36x^2)dx = 3x^2 + 12x^3 + C₁

Since f(0) = 2, we know that f'(0) = C₁ = 0. Therefore, we have:

f'(x) = 3x^2 + 12x^3

Next, we integrate f'(x) to obtain f(x):

f(x) = ∫(3x^2 + 12x^3)dx = x^3 + 3x^4 + C₂

Using the initial condition f(0) = 2, we can solve for C₂:

f(0) = C₂ = 2

Thus, the final solution for f(x) is:

f(x) = x^3 + 3x^4 + 2

We can verify that this is the correct solution by checking that f ''(x) = 6x + 36x^2 and that f(1) = 13, as given by the initial conditions.

By using the given information about the matrix a, the trace and determinant, and the algebraic multiplicities of its eigenvalues to solve for the eigenvalues of a.

To solve this problem, we can start by using the fact that the trace of a matrix is equal to the sum of its eigenvalues. Since tr(a) = 3, we know that the sum of the eigenvalues of a is 3.

Next, we can use the fact that the determinant of a matrix is equal to the product of its eigenvalues. Since det(a) = -80, we know that the product of the eigenvalues of a is -80.

Let λ1 and λ2 be the two distinct eigenvalues of a, with algebraic multiplicities m1 and m2, respectively. Then we have:

λ1 + λ2 = 3 (from tr(a) = 3)

λ1λ2 = -80 (from det(a) = -80)

We can solve this system of equations to find the values of λ1 and λ2:

λ1 = 8, m1 = 2

λ2 = -5, m2 = 1

To see why these values are correct, note that the algebraic multiplicities must add up to the size of the matrix (which is 3 in this case). We have m1 + m2 = 2 + 1 = 3, so this condition is satisfied.

Therefore, the eigenvalues of a with their algebraic multiplicities are λ1 = 8 (with multiplicity 2) and λ2 = -5 (with multiplicity 1).

Therefore, any number greater than 2 can be placed on the line to make the inequality true. In this case, the "number used to make inequality true" is 2, since it is the value of x that satisfies the inequality. However, it is important to note that this answer may differ depending on the specific inequality being used.

In order to answer this question, we need to know the inequality that we are trying to make true. Once we have that, we can figure out what number should be placed on the line to make it true. For example, let's say the inequality is 4x + 3 > 11. To solve for x, we need to isolate the variable on one side of the equation. Subtracting 3 from both sides, we get 4x > 8. Then, dividing both sides by 4, we get x > 2. .
