To find the distance DE across a river using indirect measurement, you can use the Angle-Angle (AA) Congruence Theorem.

A jogging path runs along the river from point C to point E ,passing through point A.

To find the distance DE across a river using indirect measurement, you can use the Angle-Angle (AA) Congruence Theorem.

This theorem states that if two angles of one triangle are congruent to two angles of another triangle, then the two triangles are congruent. In this scenario, you can measure the angles at A in both triangles ABC and ADE, and if they are congruent, you can conclude that the triangles are congruent by AA Congruence Theorem.

Knowing that ABC and ADE are congruent, you can use the Side-Side-Side (SSS) Congruence Theorem to find that their corresponding sides are congruent.

In particular, you can conclude that AB = AD, BC = DE, and AC = AE, which means that DE can be found by simply measuring AC and subtracting AB.

Therefore, we can use the Angle-Angle (AA) Congruence Theorem.

What is non-decreasing sequence?

Non-decreasing sequences are a generalization of binary covering arrays, which has made research on non-decreasing sequences important in both math and computer science.

Proof:

For n 2 N, let s = sup x n.

Then, there exists a m 2 N such that x m r for any r > s.

Given that x n is a non-decreasing sequence, we get x n r for any n > m.

As a result, there is a m 2 N such that for any n > m, x n r for any r > s.

Step-by-step explanation:

To solve this problem, create and solve a system of linear equations using the given information.

From the given information:

Therefore, the system of linear equations is:

\(\begin{cases}A=2B\\B=3C\\A+B+C=80000\end{cases}\)

Substitute the second equation into the first to create and equation for A in terms of C:

Answer: The data shows an association between the type of instructor and a certification in CPR. The association is that swimming instructors are less likely than tennis instructors to be certified in CPR. This can be seen from the frequency table, where all the swimming instructors are not certified in CPR, while only 4 out of 12 tennis instructors are not certified in CPR, so yes, the data does show an association between the type of instructor and a certification in CPR.

Step-by-step explanation:

The two-way frequency table shows the number of instructors who are certified or not certified in CPR, broken down by type of instructor (swimming or tennis). The data in the table allows us to see the relationship between the two variables (type of instructor and certification in CPR) and whether there is an association between them.

An association means that the values of one variable are related to the values of another variable in some way. In this case, the type of instructor (swimming or tennis) is related to whether or not the instructor is certified in CPR. The data shows that the proportion of swimming instructors who are not certified in CPR (100%) is higher than the proportion of tennis instructors who are not certified in CPR (33%). This indicates that there is an association between type of instructor and certification in CPR, with swimming instructors being less likely to be certified in CPR than tennis instructors.

It is important to note that this association does not necessarily imply causation, meaning that being a swimming instructor does not cause one to not be certified in CPR, but it could be the other way around, or it could be due to some other factors that the data does not show.

Answer:

C. (45+2+7)-(43+2+7) / 5+3

Step-by-step explanation:

To find the average rate of change of h(x) on the interval -3 ≤ x ≤ 5, we need to evaluate the following expression:

[h(5) - h(-3)] / (5 - (-3))

We have:

h(5) = 4(5) + 2 + 7 = 29

h(-3) = 4(-3) + 2 + 7 = -5

Substituting into the formula, we get:

[29 - (-5)] / (5 - (-3)) = 34 / 8 = 17 / 4

Therefore, the expression that gives the average rate of change of the function h(x) on the interval -3 ≤ x ≤ 5 is:

The interest earned and paid into Leah's account on August 31, 2017, is approximately $0.244. This is calculated using the formula for simple interest: Interest = Principal * Rate * Time.

To calculate the interest earned and paid into Leah's account on August 31, 2017, we use the formula for simple interest: Interest = Principal * Rate * Time.

In this case, the principal is $222.00 and the rate is 0.54%. However, we need to convert the rate to a decimal by dividing it by 100, giving us 0.0054.

The time is calculated as the number of days between June 17 and August 31, which is 75 days. However, since the rate is given as an annual rate, we need to express the time in years. We divide the number of days by 365 to obtain 0.2055 years.

Plugging these values into the formula, we have:

Interest = $222.00 * 0.0054 * 0.2055 = $0.244.

a) For this process, the proportion of shafts with diameter between 19.990 mm and 20.000 mm is 0.1587, approximately. The proportion of shafts with diameters between 19.990 mm and 20.010 mm is normal, with a mean of 20.005 mm and a standard deviation of 0.004 mm. The z-score is determined as follows:z= (x - μ)/ σ

Here, x = 19.990 and

z = (19.990 - 20.005)/0.004

= -3.75z

= (20.010 - 20.005)/0.004

This can be done either by using a standard normal table or using a calculator. We can use a calculator to compute the probability.

Using the calculator, the probability is approximately 0.6826. b) For this process, the probability that a shaft is acceptable is 0.8413, approximately. A shaft is considered acceptable if its diameter is between 19.990 mm and 20.010 mm. The proportion of shafts with diameters between 19.990 mm and 20.010 mm is normal, with a mean of 20.005 mm and a standard deviation of 0.004 mm. The z-score is determined as follows: z= (x - μ)/ σHere,

x = 20 and z = (20 - 20.005)/0.004

To answer the questions about group G with order 77: (1) Show that there are normal subgroups H and K of the group with order 7 and 11, respectively.

Since the order of G is 77, by the Sylow theorems, there exist Sylow 7-subgroups and Sylow 11-subgroups in G.

Let H be a Sylow 7-subgroup of G and K be a Sylow 11-subgroup of G. Since Sylow subgroups are conjugate to each other, H and K are both normal subgroups of G.

(2) Show that HK={hk|h∈H, k∈K} is an Abelian subgroup of group G.

Since H and K are normal subgroups of G, we have that HK is a subgroup of G. To show that HK is an Abelian subgroup, we need to prove that for any elements hk and h'k' in HK, their product is commutative.

Let hk and h'k' be arbitrary elements in HK. Since H and K are normal subgroups, we have that h'khk' = kh'h. Thus, the product hk h'k' is equal to kh'h, which implies that HK is an Abelian subgroup.

(3) Show that HK=G.

To show that HK=G, we need to prove that every element g in G can be expressed as a product hk, where h∈H and k∈K.

Since H and K are normal subgroups of G, their intersection H∩K is also a normal subgroup of G. By Lagrange's theorem, the order of H∩K divides both the order of H (which is 7) and the order of K (which is 11). Since 7 and 11 are coprime, the only possible order for the intersection is 1.

Thus, H∩K={e}, where e is the identity element of G. This implies that every element g in G can be uniquely expressed as g = hk, where h∈H and k∈K. Therefore, HK=G.

(4) Show that G is a cyclic group.

Since HK=G, and HK is an Abelian subgroup, we have that G is an Abelian group. Every Abelian group of prime order is cyclic. Since the order of G is 77, which is not prime, G cannot be cyclic.

Therefore, G is not a cyclic group.

a.we get, `A = √(2α³/π)`.

b.`⟨H⟩ = (3/4)hω - (h²/4ma²)` where `a = α/√(mω/h)`.

c.we can say that the variational principle is valid in this case.

(a) Let's find the normalization constant A.

We know that the integral over all space of the absolute square of the wave function is equal to 1, which is the requirement for normalization.  `∫⟨ψ|ψ⟩dx= 1`

Hence, using the given trial wavefunction, we get, `∫⟨ψ|ψ⟩dx = ∫ |A/(x^2+α²)|²dx= A² ∫ dx / (x²+α²)²`

Using a substitution `x = α tan θ`, we get, `dx = α sec² θ dθ`

Substituting these in the above integral, we get, `A² ∫ dθ/α² sec^4 θ = A²/(α³) ∫ cos^4 θ dθ`

Using the identity, `cos² θ = (1 + cos2θ)/2`twice, we can write,

`A²/(α³) ∫ (1 + cos2θ)²/16 d(2θ) = A²/(α³) [θ/8 + sin 2θ/32 + (1/4)sin4θ/16]`

We need to evaluate this between `0` and `π/2`. Hence, `θ = 0` and `θ = π/2` limits.

Using these limits, we get,`⟨ψ|ψ⟩ = A²/(α³) [π/16 + (1/8)] = 1`

Therefore, we get, `A = √(2α³/π)`.

Hence, we can now write the wavefunction as `ψ(x) = √(2α³/π)/(x²+α²)`.  

(b) Using the wave function found in part (a), we can now determine the expectation value of energy using the time-independent Schrödinger equation, `Hψ = Eψ`. We can write, `H = (p²/2m) + (1/2)mω²x²`.

The first term represents the kinetic energy of the particle and the second term represents the potential energy.

We can write the first term in terms of the momentum operator `p`.We know that `p = -ih(∂/∂x)`Hence, we get, `p² = -h²(∂²/∂x²)`Using this, we can now write, `H = -(h²/2m) (∂²/∂x²) + (1/2)mω²x²`

The expectation value of energy can be obtained by taking the integral, `⟨H⟩ = ⟨ψ|H|ψ⟩ = ∫ψ* H ψ dx`Plugging in the expressions for `H` and `ψ`, we get, `⟨H⟩ = - (h²/2m) ∫ψ*(∂²/∂x²)ψ dx + (1/2)mω² ∫ ψ* x² ψ dx`Evaluating these two integrals, we get, `⟨H⟩ = (3/4)hω - (h²/4ma²)` where `a = α/√(mω/h)`.

(c) Since we have an approximate ground state wavefunction, we can expect that the expectation value of energy ⟨H⟩ should be greater than the true ground state energy.

Hence, the value obtained in part (b) should be greater than the true ground state energy obtained by solving the Schrödinger equation exactly.

Therefore, we can say that the variational principle is valid in this case.

P-value for the test is to be determined.

To find the p-value, we need to perform a hypothesis test. Here, we have to test whether the null hypothesis is true or not.

Hypothesis statements:

Null hypothesis (H0): µ = 60 km (The population mean is 60 km)

Alternative hypothesis (Ha): µ ≠ 60 km (The population mean is not equal to 60 km)

Level of significance, α = 0.05

Z-score formula is given as,Z = (x - µ) / (σ/√n)

Where,x = Sample mean = 59.1 km

µ = Population mean

σ = Standard deviation of the population = 2.31 km

n = Sample size

We have,σ/√n = 2.31/√n

For α = 0.05, the two-tailed critical values are ±1.96

Now, the calculated Z-score is given as,

Z = (59.1 - 60) / (2.31/√n)

Z = - (0.9) * ( √n / 2.31)

P(Z < -1.96) = 0.025 and P(Z > 1.96) = 0.025
