By using congruency, it can be calculated that

x = 6, y = 5

What are congruent triangles?

Two triangles are said to be congruent if their corrosponding sides and corrosponding angles are same. There are different axioms of congruency. They are-

AAS axiom, SAS axiom, ASA axiom, SSS axiom, RHS axiom

It is given that \(\Delta\) ABC \(\cong\) \(\Delta\) BAD

So \(\angle\)CAB = \(\angle\)ABD [Corrosponding parts of congruent triangles are congruent]

4y = 20

y = \(\frac{20}{4}\\\)

y = 5

Also,

AC = BD [Corrosponding parts of congruent triangles are congruent]

For a student who participate in a wide variety of extra-curricular memorial high school, the probability of the union of being either a freshman or senior is equals to the 0.50.

We have students who attend memorial high school have a wide variety of extra-curricular activities.

Probability of student who likely to join the dance team = 38% = 0.38

Probability of student who likely to participate in the school play = 18% = 0.18

Probability of students who likely to join the yearbook club = 42% = 0.42

Probability of students who likely to join the marching band = 64% = 0.64

Also, students have equal probabilities of being freshmen, sophomores, juniors, or seniors.

So, the probability ( a student is senior )

= 1/4 = 0.25

The probability ( a student is freshman )

= 1/4 = 0.25

We have to determine the union of being either a freshman or senior. Now, the probability of the union of disjoint or independent events is the sum of their individual probabilities.

So, probability ( a student is freshman or senior) = P( freshman ∪ senior )

= P( freshman) + P( senior)

= 0.25 + 0.25 = 0.50

Hence, required probability is 0.50.

To draw the digital circuit corresponding to the expression x(yz' + z), we can break it down into logical operations.

The given expression involves the logical operations of NOT, AND, and OR. In the circuit diagram, we would have three inputs: x, y, and z. Firstly, we need to calculate the complement of z (represented as z') using a NOT gate. The output of the NOT gate would then be connected to one input of the AND gate. The other input of the AND gate would be connected directly to the input y.

The output of the AND gate would be connected to one input of the OR gate. Finally, the input x would be directly connected to the other input of the OR gate. The output of the OR gate would be the result of the expression x(yz' + z).

The circuit would consist of an input x connected directly to an OR gate, while an input y would be connected to one input of an AND gate along with the complement of input z (z') obtained through a NOT gate. The output of the AND gate would be connected to the other input of the OR gate, and the output of the OR gate would represent the result of the given expression x(yz' + z).

Therefore, the present value of the perpetuity that pays $1,800 per year forever, assuming a 5% interest rate, is $36,000. To find the present value of a perpetuity that pays $1,800 per year forever, we can use the formula:
Present Value = Cash Flow / Interest Rate

In this case, the cash flow is $1,800 and the interest rate is 5%. Plugging these values into the formula, we get:
Present Value = $1,800 / 0.05. Simplifying this equation, we find that:

The statement, When two events are disjoint, they are also independent is false.

In a sample space, we can use probability laws to determine the probabilities of these events and how they relate to each other. Disjoint Events: Two events are non-overlapping or mutually exclusive if they have no common outcome. Mathematically, this can be written as, P(B ∩ A) = 0 --(1)

Independent Events: Events are independent when they do not "affect" the probability of another event occurring. Mathematically written as:

P(B/A) = P(B) P(A and B)

=> P(B ∩ A) = P(B) × P(A) --(2)

(1) ) and (2) events cannot be independent unless they overlap. That is, if events do not overlap, they are also dependent. Hence, disjoint events are not independent that means the above statement is false.

The inductance of the toroid is (299.8*\(600^{2}\)*π)/2 = 7.04 x \(10^{-3}\) H.

Area is a quantity that measures the size of a two-dimensional surface or shape. It is expressed in square units such as square centimeters, square meters or square kilometers. Area is used to describe the size of a garden, a house, a room, a city and much more. It can also be used to calculate the amount of material required for a project, such as paint, carpet or tiles. Knowing the area of a shape can help to calculate costs, and to make sure that enough materials are ordered.

The inductance of a toroid coil can be calculated using the following formula: L = (μN^2*A)/l, where μ is the permeability of the core material, N is the number of turns of the coil, A is the cross-sectional area of the toroid, and l is the length of the coil. In the case of a toroid with large radius b, the cross-sectional area A is approximately equal to π\(b^{2}\) and the length of the coil is l=2πb. Therefore, the inductance of the toroid is L=(μN^2*π\(b^{2}\))/(2πb)= (μN^2*π)/2.

(b) For the given toroid with 600 turns, iron core (μ=299.8), a=8.0 cm and c=9.0 cm, the inductance can be calculated as follows:

L = (299.8*\(600^{2}\)*π)/2 = 7.04 x \(10^{-3}\) H.

\(A^{100} \approx PD^{100} P^{-1}\) is the diagonal matrix with the diagonal entries being the 100th power of the corresponding entries in D.

Thus, A¹⁰⁰ can be expressed as \(A^{100} \approx PD^{100} P^{-1}\).Suppose \(A \approx PDP^{-1}\)for square matrices P, D, D diagonal.

Then a¹⁰⁰ can be expressed as a = PD¹⁰⁰P⁻¹

where D¹⁰⁰ is the diagonal matrix with the diagonal entries being the 100th power of the corresponding entries in D.

Step-by-step explanation:

Given a = PDP⁻¹ for square matrices P, D, D diagonal.

To express a¹⁰⁰ as a = PD¹⁰⁰P⁻¹, let us find D¹⁰⁰ first.

The diagonal entries of D are the eigenvalues of A, so the diagonal entries of D¹⁰⁰ are the eigenvalues of A¹⁰⁰.

Since A = PDP⁻¹,   A¹⁰⁰ = PD¹⁰⁰P⁻¹,  D¹⁰⁰ is the diagonal matrix with the diagonal entries being the 100th power of the corresponding entries in D. Thus, a¹⁰⁰ can be expressed as a = PD¹⁰⁰P⁻¹.a^100 can be computed by taking the diagonal matrix D and raising each diagonal element to the power of 100,

then multiplying P on the left and P^(-1) on the right of the resulting diagonal matrix.

The probability that more than 7 of them weigh 65 lb or more is 0.0123.

A polynomial with only terms is a binomial. An illustration of a binomial is x + 2, where x and 2 are two distinct terms. Additionally, in this case, x has a coefficient of 1, an exponent of 1, and a constant of 2. As a result, a binomial is a two-term algebraic expression that contains a constant, exponents, a variable, and a coefficient. When each trial has the same probability of achieving a given value, the number of trials or observations is summarized using the binomial distribution. The likelihood of observing a specific number of successful outcomes in a specific number of trials is determined by the binomial distribution.

Given,

The Australian sheep dog is a breed renowned for its intelligence and work ethic. it is estimated that 40% of adult Australian sheep dogs weigh 65 pounds or more. a sample of 10 adult dogs is studied.

Let x be the number of sheep having 65 lb or more weight out of n;

Binomial function:

P(X = x) = ⁿCₓ Pˣ qⁿ⁻ˣ

When x = 0,1 2,..n

q = 1-p

n = 10

So,

P(X>7) = P(X = 8) + P(X = 9) +P(X = 10)

P(X >7) = ¹⁰C₈ (0.40)⁸ q¹⁰⁻⁸ + ¹⁰C₉(0.40)⁹ q¹⁰⁺⁹ + ¹⁰C₁₀ (0.40)¹⁰

P(X>7) = (0.40)⁸ (45× 0.36 + 10× 0.24+0.16)

P(X>7) = (0.40)⁸ (16.2 +2.4 + 0.16)

P(X>7) = 0.40⁸ × 18.76
