Assuming 100% efficiency, the current in the secondary coil will be the same as the current in the primary coil.

The current in the secondary coil is dependent on the voltage ratio of the primary and secondary coils. If the voltage ratio of the coils is the same as the turns ratio, then the current in the secondary coil will be identical to that in the primary coil. Therefore, assuming 100% efficiency, the current in the secondary coil will be the same as the current in the primary coil.

The current in the secondary coil is determined by the voltage ratio of the primary and secondary coils. The voltage ratio is equal to the turns ratio, which is the ratio of the number of turns in the secondary coil to the number of turns in the primary coil. In an ideal transformer with 100% efficiency, the power output in the secondary coil will be equal to the power input in the primary coil. Since power is equal to voltage multiplied by current, and the voltage ratio is equal to the turns ratio, the current in the secondary coil will be the same as the current in the primary coil.

Therefore, assuming 100% efficiency, the current in the secondary coil will be the same as the current in the primary coil.

To calculate the inclusion probability for unit 6 (PSU level) in the first stage of PPS without replacement, we need to divide the number of sampling units in the population by the total number of sampling units selected in the first stage.

Looking at the provided data, we can see that there are a total of 10 sampling units (Mi) in the dataset.

In PPS without replacement, the first sampling unit is selected with certainty. So, the inclusion probability for unit 6 (PSU level) is:

Inclusion probability = 1 / Total number of sampling units selected in the first stage

                    = 1 / 10

                    = 0.1

Therefore, the inclusion probability for unit 6 (PSU level) in the first stage of PPS without replacement is 0.1 or 10%.

Numbers play a crucial role in helping us predict the ebbs and flows in our lives. They are used to measure and quantify patterns and cycles that occur in our daily lives, such as circadian rhythms.

Circadian rhythms are the physical, mental, and behavioral changes that follow a 24-hour cycle, responding primarily to light and darkness in an organism's environment. Numbers help us measure and track these rhythms, allowing us to predict when we will feel awake or sleepy, hungry or full, and so on.

For example, we know that the average human circadian rhythm is 24.2 hours, and that our bodies produce the hormone melatonin at night to help us sleep. By measuring and tracking these numbers, we can predict when we will feel tired and need to sleep, and when we will feel awake and alert.

Numbers also help us predict other patterns in our lives, such as our menstrual cycles, the best times to exercise, and when we are most likely to get sick. By tracking and measuring these numbers, we can better understand and predict the ebbs and flows in our lives and make more informed decisions about our health and well-being.

The given convex optimization problem aims to minimize the objective function, which is a quadratic term WERD1^T w'w2, subject to the constraint wr > 1. To derive the Lagrangian dual, we introduce the Lagrange multiplier X.

The Lagrangian function is constructed by adding the product of the Lagrange multiplier and the constraint to the objective function, resulting in L(w, X) = WERD1^T w'w2 + X(wr - 1). The Lagrangian dual is obtained by minimizing the Lagrangian function with respect to w while maximizing it with respect to X.

The Lagrangian dual is a powerful tool in optimization as it provides a way to transform a constrained optimization problem into an unconstrained one. In this case, introducing the Lagrange multiplier X allows us to incorporate the constraint wr > 1 into the objective function through the Lagrangian function L(w, X). By minimizing L(w, X) with respect to w and maximizing it with respect to X, we can find the optimal values of w and X that satisfy both the objective and the constraint. The Lagrangian dual thus provides insight into the trade-off between the objective and the constraint and helps us understand the duality between the primal and dual problems in convex optimization.

Answer:

C. 1:5

Step-by-step explanation:

The probability that X is between 57 and 105 is 0.8914.

Given:

* X is normally distributed with mean=90 and standard deviation=12

* P(57 < X < 105)

Solution:

* Convert the given values to z-scores:

   * z = (X - μ) / σ

   * z = (57 - 90) / 12 = -2.50

   * z = (105 - 90) / 12 = 1.25

* Use the z-table to find the probability:

   * P(Z < -2.50) = 0.0062

   * P(Z < 1.25) = 0.8944

* Add the probabilities to find the total probability:

   * P(57 < X < 105) = 0.0062 + 0.8944 = 0.8914

Therefore, the probability that X is between 57 and 105 is 0.8914.

Answer: Sweets needs to sell to cover its fixed and variable costs.

Let x be the number of dozens of milk fritters that Royal Sweets needs to sell to break even.

Revenue from selling x dozens of milk fritters = price per dozen x number of dozens sold = $3.50x

Total cost = fixed cost + variable cost

Total cost = $15,000 + ($2.00 x)

At break-even point, revenue = total cost, so:

$3.50x = $15,000 + ($2.00 x)

$1.50x = $15,000

x = 10,000/1.5

x = 6,666.67

Therefore, Royal Sweets needs to sell approximately 6,667 dozens of milk fritters to break even.

Answer: \(x= \frac{3}{4}\)

Mrs. Frizzle can assign her students to lab groups of two or three students in 18 and 12 ways respectively.
To find the number of ways to form lab groups of two students, we need to calculate the number of combinations of 9 students taken 2 at a time. This can be represented as "9C2" or "9 choose 2".

The formula for combinations is nCr = n! / (r!(n-r)!), where n is the total number of objects to choose from and r is the number of objects to choose.
So, for lab groups of two students, the calculation would be:
9C2 = 9! / (2!(9-2)!)
    = 9! / (2!7!)
    = (9 * 8 * 7!) / (2! * 7!)
    = (9 * 8) / 2!
    = 36 / 2
    = 18
Therefore, there are 18 ways to form lab groups of two students.

To find the number of ways to form lab groups of three students, we need to calculate the number of combinations of 9 students taken 3 at a time. This can be represented as "9C3" or "9 choose 3".

Using the same formula for combinations, the calculation would be:
9C3 = 9! / (3!(9-3)!)
    = 9! / (3!6!)
    = (9 * 8 * 7!) / (3! * 6!)
    = (9 * 8) / 3!
    = 72 / 6
    = 12
Therefore, there are 12 ways to form lab groups of three students.

In conclusion, Mrs. Frizzle can assign her students to lab groups of two or three students in 18 and 12 ways respectively.

To determine if the sequence {an} is a solution of the recurrence relation an = 8an-1 – 16an-2, we need to substitute the given values of an and check if the equation holds true.

a) If an = 1, then we have:

an = 1
an-1 = a0 (since we don't have any values before a0)
an-2 = a-1 (which is not defined since a-1 is outside the domain of the sequence)

Substituting these values in the recurrence relation, we get:

1 = 8a0 - 16a-1 (using a0 = a-1 = 0, since they are undefined)

Simplifying this equation, we get:

1 = 0, which is not true. Therefore, the sequence {an} is not a solution of the recurrence relation if an = 1.

b) If an = 4, then we have:

an = 4
an-1 = a3
an-2 = a2

Substituting these values in the recurrence relation, we get:

4 = 8a3 - 16a2

Simplifying this equation, we get:

2 = 4a3 - 8a2
1/2 = 2a3 - 4a2
1/8 = a3 - 2a2

Therefore, the sequence {an} is a solution of the recurrence relation if an = 4.

In summary, the sequence {an} is not a solution of the recurrence relation if an = 1, but it is a solution if an = 4. This is because the recurrence relation is not satisfied for an = 1, but it is satisfied for an = 4.
