Answer:

Where is the Question?

Step-by-step explanation:

The probability that at least one child would draw the nickel too small is: P(X ≥ 1) = 1 - P(X = 0).

b) To find the probability that exactly 4 children would draw the nickel too small, we can use the binomial probability formula. The formula is: P(X = k) = (nCk) * (p^k) * (q^(n-k)), where n is the number of trials, k is the number of successes, p is the probability of success, and q is the probability of failure.

In this case, n = 8 (as 8 children are chosen), k = 4 (as exactly 4 children drawing the nickel too small), p = 0.15 (as the probability of a child drawing the nickel too small), and q = 1 - p = 1 - 0.15 = 0.85.

So, the probability that exactly 4 children would draw the nickel too small is: P(X = 4) = (8C4) * (0.15^4) * (0.85^(8-4)).

c) To find the probability that at least one child would draw the nickel too small, we can use the complement rule. The probability of at least one success is equal to 1 minus the probability of no success.

The probability of no success (all children drawing the nickel of the right size) is given by: P(X = 0) = (8C0) * (0.15^0) * (0.85^8).

Therefore, the probability that at least one child would draw the nickel too small is: P(X ≥ 1) = 1 - P(X = 0).

Answer: the anscer is C i think

Step-by-step explanation:

The solution is of the form y = tr where r = 5/14 for the given differential equation.

Given differential equation:

t²y''- 10ty' + 28y = 0

Let's assume the solution is of the form y = tr. We need to find the values of r for which this form of the solution holds.Let's differentiate the solution y = tr with respect to t in order to solve for the first and second derivatives of y as follows:

y = tr.....(1)

First derivative of y w.r.t t is given by:

y' = r.....(2)

Second derivative of y w.r.t t is given by:

y'' = 0.....(3)

Substituting equations (1), (2), and (3) in the given differential equation, we get:

(t² * 0) - 10t * r + 28(tr) = 0

Simplifying, we get:

(28r - 10) * t = 0

Since t > 0, then the coefficient of t must be zero. Thus,

28r - 10 = 0

=> 28r = 10

=> r = 10/28 (reduced)

=> r = 5/14

So, the value of r is 5/14 when the given differential equation has solutions of the form y = tr for t > 0.

In summary, the solution is of the form y = tr where r = 5/14 for the given differential equation.

The maximum amount of profit the company can make is 9274

Differentiation is the rate of change of one quantity with respect to the other.

It is the ratio of the change in one quantity, usually the dependent quantity to the change in another related quantity, usually the independent quantity.

Analysis:

y= -6x^2 + 600x - 5726

differentiating the equation,

dy/dx = -12x + 600

for maximum selling price, dy/dx = 0

-12x + 600 = 0

12x = 600

x = 50

The maximum selling price is 50, so substituting x to find y

y = -6(50)(50) + 600(50) - 5726 = 9274

In conclusion, the maximum amount of profit the company can make is 9274.

A complete graph is one in which there is an edge connecting every vertex to every other vertex. In order to determine for what values of n a complete graph with n vertices has an Euler circuit and a Hamiltonian circuit, let's discuss the definitions and requirements of each type of circuit.

1. Euler Circuit: An Euler circuit is a path that traverses each edge of a graph exactly once and returns to its starting vertex. For a graph to have an Euler circuit, all vertices must have an even degree (number of edges connected to the vertex).

2. Hamiltonian Circuit: A Hamiltonian circuit is a path that visits every vertex in a graph exactly once and returns to its starting vertex. A complete graph always has a Hamiltonian circuit, regardless of the number of vertices.

Now, let's determine for what values of n a complete graph has an Euler circuit:

In a complete graph with n vertices, each vertex is connected to every other vertex, which means the degree of each vertex is (n-1). For a complete graph to have an Euler circuit, all vertices must have an even degree. This implies that (n-1) must be even, so n must be odd.

So, for a complete graph with n vertices to have an Euler circuit, n must be an odd number.

In summary:
- A complete graph with n vertices always has a Hamiltonian circuit.
- A complete graph with n vertices has an Euler circuit if n is an odd number.

Step-by-step explanation:

if this is simple interest the formula is A=P(1+rt)

A=final formula

P=initial principal balance

r=annual interest rate

t=time (in years)

so, A=180,000(1+3x10) which equals 5580000

Answer: try the answer B

Step-by-step explanation:

The correct answer is A. The null hypothesis is rejected in error.

In statistical hypothesis testing, a Type II error occurs when the null hypothesis is incorrectly retained or failed to be rejected when it is actually false.

In other words, a Type II error happens when the researcher concludes that there is no significant difference or relationship between variables when, in reality, there is.

It is a false negative result, as the researcher fails to detect a true effect or relationship.

Option A accurately describes Type II error, while the other options are not related to Type II error.

Option B refers to rejecting the research hypothesis, which is not a Type II error but rather a Type I error.

Option C refers to the study being underpowered, which may increase the likelihood of both Type I and Type II errors but is not a direct description of Type II error.

Option D mentions double-blinding, which is a methodological consideration and not directly related to Type II error.

Option E refers to accepting the research hypothesis in error, which is not a Type II error but rather a correct decision or Type I error.

Step-by-step explanation:

The steady-state output per worker (y*) is given by y* = A*(k*)^(1/3), and the level of technology (A) remains constant in the steady state.

To derive the steady-state output per worker (y*) in the Solow growth model, we start with the production function:

y = Ak^(1/3)

Where y represents output per worker, A is the level of technology, and k is capital per worker. In the steady state, capital per worker remains constant, so we have dk/dt = 0, where d represents the derivative.

Taking the derivative of the production function with respect to time (t), we get:

dy/dt = (dA/dt)k^(1/3) + A(1/3)k^(-2/3)dk/dt

Since dk/dt = 0 in the steady state, the equation simplifies to:

dy/dt = (dA/dt)k^(1/3)

In the steady state, output per worker does not change over time, so dy/dt = 0. This leads to:

(dA/dt)k^(1/3) = 0

Since k^(1/3) is positive, we must have dA/dt = 0. This means that the level of technology (A) remains constant in the steady state.

Now, substituting A = A* (where A* represents the steady-state level of technology) into the production function, we have:

y* = A*(k*)^(1/3)

where k* represents the steady-state capital per worker.

Therefore, the steady-state output per worker (y*) is given by y* = A*(k*)^(1/3), and the level of technology (A) remains constant in the steady state.

Step-by-step explanation:

The slope of bar (AB) is (5-2)/(4-2) = 3/2, and the slope of bar (CD) is (6-3)/(9-7) = 3/2. Since both slopes are equal, we can conclude that bar (AB) and bar (CD) are parallel.

To prove that bar (AB) and bar (CD) are congruent, we need to show that the distance between points A and B is equal to the distance between points C and D. We can use the distance formula to calculate these distances:

Distance between A and B:

d(AB) = sqrt((4-2)^2 + (5-2)^2) = sqrt(20)

Distance between C and D:

d(CD) = sqrt((7-9)^2 + (3-6)^2) = sqrt(13)

Since sqrt(20) is not equal to sqrt(13), we can conclude that bar (AB) and bar (CD) are not congruent.

To determine whether bar (AB) and bar (CD) are parallel, we can calculate their slopes. The slope of bar (AB) is (5-2)/(4-2) = 3/2, and the slope of bar (CD) is (6-3)/(9-7) = 3/2. Since both slopes are equal, we can conclude that bar (AB) and bar (CD) are parallel.

Answer: There are a total of 297 students in the 7th grade. Rough estimates would say that about half of that number are boys and half are girls. Asking only 50 random girls would be biased because not only would it not be all of the girls (the number of girls would be around 148 or 149) but it would also be ignoring the roughly 148 to 149 boys there are on estimate. The sample would be biased because it would be ignoring the opinions of more than half the seventh grade.
