Boone Middle School

Step-by-step explanation:

To compare the percentage of music students who play the violin at Boone Middle School and Morgan Middle School, we need to first find the percentage of music students who play the violin at Morgan Middle School.

If we assume that Morgan Middle School has 100 music students, 58% of them play the violin. Therefore, the number of music students who play the violin at Morgan Middle School is:

58/100 x 100 = 58

Now we can compare the percentage of music students who play the violin at each school:

Therefore, [Boone Middle School has a greater percentage of music students who play the violin.]

The length of the shadow casted by the high rise building is approximately 37.7 feet

The image in the question forms a right triangle:

Angle θ = 57 degrees

Opposite to angle θ = 58 feet

Adjacent to angle θ = x

To solve for x ( length of the shadow casted by the building ), we use the trigonometric ratio.

Note: tangent = opposite / adjacent

Hence:

tan( θ ) = opposite / adjacent

Plug in the values:

tan( 57° ) = 58ft / x

Cross multiply and solve for x:

x × tan( 57° ) = 58ft

x = 58ft / tan( 57° )

x = 37.7 ft

Therefore, the value of x is 37.7 feet.

ANSWER:

The Pythagorean theorem is used to find the hypotenuse of a triangle.

=> AC² = AB² + BC²

In squares, the length of the side can be calculated by finding the square root of the area.

The probability of guessing the correct answer for each question is 1/4, while the probability of guessing incorrectly is 3/4.

To calculate the probability of answering at most one correct answer, we need to consider two cases: answering zero correct answers and answering one correct answer.

For the case of answering zero correct answers, the probability can be calculated as (3/4)^5, as there are five independent attempts to answer incorrectly.

For the case of answering one correct answer, we have to consider the probability of guessing the correct answer on one question and incorrectly guessing the rest. Since there are five questions, the probability for this case is 5 * (1/4) * (3/4)^4.

To obtain the probability of answering at most one correct answer, we sum up the probabilities of the two cases:

Probability = (3/4)^5 + 5 * (1/4) * (3/4)^4.

Therefore, by calculating this expression, you can determine the probability of answering at most one correct answer among five questions when guessing randomly.

Joanna can assemble her bracelet in 30 ways.

It is given that Joanna has 6 beads and of those 6 beads, 2 are of the same color.

The rest 4 are of different colors.

Six beads can be arranged in a circle in 6!/6 ways.

This means that the six beads can be arranged in 5! ways.

Since this is a bracelet, it can be flipped around. Therefore, it can be arranged in 5!/2 ways.

5!/2 = 5*4*3*2*1/2

= 60

Now, we know that two beads are of the same color. Therefore, we must divide this by two again.

Therefore, we get:

60/2 = 30

The six beads can be arranged in 30 ways to make the bracelet.

Therefore, we have found that Joanna can assemble her bracelet in 30 ways.

The statement that is true in this scenario is D) Monetary base decreases while money supply increases if Bank A does not lend. In this case, when Bank A sells a $100 security to the Fed, the monetary base decreases because the Fed pays Bank A for the security with reserves.

This reduces the amount of reserves held by Bank A, leading to a decrease in the monetary base. However, if Bank A does not lend out the reserves it receives from the Fed, the money supply remains unchanged.

The reason the statement is true is because the monetary base consists of the currency in circulation and the reserves held by banks at the central bank. When Bank A sells the security to the Fed, it reduces its reserves, which are part of the monetary base. However, if Bank A holds onto the reserves instead of lending them out, the money supply does not increase. Money supply depends on the lending and borrowing activities of banks, and in this scenario, Bank A's decision not to lend prevents an increase in the money supply.

The characteristic polynomial is 0, which implies that the system is not stable.

To derive the equations for the diagram shown in the figure, let's analyze each component:

Input: R(s)

Feedback signal: C(s)

Error: E(s)

Actuator: M(s)

Plant transfer function: G(s)

Disturbance input: D(s)

Controller transfer function: F(s)

Output: Y(s)

Based on the diagram, we can write the equations:

Error equation:

E(s) = R(s) - C(s)

Actuator equation:

M(s) = K * E(s)

Plant equation:

Y(s) = G(s) * M(s)

Output equation:

C(s) = Y(s) + D(s)

Now, let's substitute the corresponding expressions from the given equation:

C(s) = 15s + 2

M(s) = 4 * C(s) + 3s + 1

Substituting M(s) into the output equation:

C(s) = G(s) * (4 * C(s) + 3s + 1) + D(s)

Simplifying the equation:

C(s) = 4 * G(s) * C(s) + 3 * G(s) * s + G(s) + D(s)

Rearranging the equation:

C(s) - 4 * G(s) * C(s) = 3 * G(s) * s + G(s) + D(s)

Factoring out C(s):

C(s) * (1 - 4 * G(s)) = 3 * G(s) * s + G(s) + D(s)

Dividing both sides by (1 - 4 * G(s)):

C(s) = (3 * G(s) * s + G(s) + D(s)) / (1 - 4 * G(s))

Therefore, the equation for C(s) is:

C(s) = (3 * G(s) * s + G(s) + D(s)) / (1 - 4 * G(s))

The characteristic polynomial can be obtained by setting the denominator equal to zero:

1 - 4 * G(s) = 0

Solving for G(s):

4 * G(s) = 1

G(s) = 1/4

Therefore, the characteristic polynomial is:

1 - 4 * (1/4) = 0

Simplifying:

1 - 1 = 0

The characteristic polynomial is 0, which implies that the system is not stable.

The complete question is:

Derive the output C(s), error E(s), and actuator M(s) equations for the diagram in the figure, and obtain the characteristic polynomial.

The false statement is: "The researchers would come to the conclusion that the programme was successful if they used a significance level of 1%."

What is significance level?

A significance level, denoted by α, is the threshold chosen by researchers to determine the level of evidence required to reject the null hypothesis. It represents the maximum acceptable probability of making a Type I error (incorrectly rejecting the null hypothesis when it is true).

In this case, the given p-value is 0.003. If the null hypothesis is true, the p-value represents the likelihood of obtaining a test statistic that is equally extreme to or more extreme than the one that was observed. It offers proof that the null hypothesis is false.

We can conclude that there is strong evidence to reject the null hypothesis in favour of the alternative hypothesis because the p-value is 0.003, which is lower than any often used significance level like 0.05 or 0.01. Thus, if the researchers apply a 5% level of significance, they would draw the conclusion that the programme was successful.

However, if the researchers use a significance level of 1%, they would require even stronger evidence to reject the null hypothesis. Since the p-value of 0.003 is greater than 0.01, they would not be able to reject the null hypothesis at the 1% significance level and would not conclude that the program was effective.
