D is the right response, meaning that if attendance increases by 1%, the anticipated mean score will rise by 0.341 percentage points.

What is Statistics?

The study of gathering, analysing, interpreting, presenting, and arranging data in a certain way is the focus of the mathematic branch known as statistics. The act of gathering data, classifying it, presenting it in a way that makes it understandable, and then conducting additional analyses of the data is known as statistics. Statistics is also the process of drawing inferences from samples of data gathered through experiments or surveys. Statistics are also used to operate in a variety of fields, including psychology, sociology, geology, probability, and more.

Results of an EXA are a dependent variable.

Percentage Attendance is a standalone factor.

As a result, the regession equation is Scores received = 39.390 + 0.341*X.

In other words, if we increase attendance by 1%, the estimated mean score received will increase by 0.341 percentage, according to the slope of the regression line.

Therefore, D is the right response, meaning that if attendance increases by 1%, the anticipated mean score will rise by 0.341 percentage points.

To develop the Branch and Bound (B&B) tree for the given problem, follow these steps:

1. Start with the initial B&B tree, where the root node represents the original problem.

2. Choose \($x_1$\) as the branching variable at node 0. Add two child nodes: one for

\($x_1 \leq \lfloor x_1 \rfloor$ \\(floor of $x_1$) and one for $x_1 \geq \lceil x_1 \rceil$ (ceiling of $x_1$).\)

3. At each node, perform the following steps:

  - Solve the relaxed linear programming (LP) problem for the node, ignoring the integer constraints.

  - If the LP solution is infeasible or the objective value is lower than the current best solution, prune the node and its subtree.

  - If the LP solution is integer, update the current best solution if the objective value is higher.

  - If the LP solution is non-integer, choose the fractional variable with the largest absolute difference from its rounded value as the branching variable.

4. Repeat steps 2 and 3 for each unpruned node until all nodes have been processed.

5. The node with the highest objective value among the integer feasible solutions is the optimal solution.

6. Optionally, backtrace through the tree to retrieve the optimal solution variables.

Note: The specific LP problem and its constraints are missing from the given question, so adapt the steps accordingly.

Step-by-step explanation:

P is currently at a height of 3 cm. in 2 days it'll have grown 2 cm (0.5 x 2), meaning it'll measure 5 cm.

Q is currently at a height of 5 cm. in 2 days it'll have grown 3 cm (1.5 x 2), meaning it'll measure 8cm.

Q will be 3 cm taller than P

The expression that will help to calculate the area of the figure is A = (n-6)² and the area will be 25 units² when n = 11.

A term may be a number, a variable, the product of two or more variables, a number and a variable, or any combination of these.

A single term or a collection of phrases can be used to create an algebraic expression.

For instance, 4x and y are the two terms in the formula 4x + y.

So, we have a square as a figure.

The side of the figure is (n - 6).

Now, the expression to find the area of the square will be:

A = (n-6)²

Now, evaluate when n = 11 as follows:

A = (n-6)²

A = (11-6)²

A = (5)²

A = 25 units²

Therefore, the expression that will help to calculate the area of the figure is A = (n-6)² and the area will be 25 units² when n = 11.

The Equivalent Units of Production for conversion costs is 16,750 units. The total material cost per unit is P0.94. The total manufacturing cost per unit is P2.59. The total cost for Started and Completed is P47,680. The total cost for Work in Process, Ending Inventory is P5,180.

21. The Equivalent Units of Production-Conversion Cost = 16,750 units.

22. The total material cost per unit = P0.94.

23. The total manufacturing cost per unit = P2.59.

24. The total cost for Started and Completed = P47,680.

25. The total cost for Work in Process, Ending Inventory = P5,180.

To calculate the required values, we'll use the FIFO method.

21. Equivalent Units of Production-Conversion Cost:

Equivalent Units of Production = Units completed + (Ending work in process inventory * Degree of completion)

Equivalent Units of Production = 17,500 + (2,000 * 3/4)

Equivalent Units of Production = 17,500 + 1,500

Equivalent Units of Production = 19,000 units

22. Total Material Cost per Unit:

Total Material Cost per Unit = Total material costs / Equivalent Units of Production

Total Material Cost per Unit = P16,500 / 17,500

Total Material Cost per Unit = P0.94

23. Total Manufacturing Cost per Unit:

Total Manufacturing Cost per Unit = (Total material costs + Conversion costs) / Equivalent Units of Production

Total Manufacturing Cost per Unit = (P16,500 + P23,945) / 17,500

Total Manufacturing Cost per Unit = P40,445 / 17,500

Total Manufacturing Cost per Unit = P2.59

24. Total Cost for Started and Completed:

Total Cost for Started and Completed = Units completed * Total Manufacturing Cost per Unit

Total Cost for Started and Completed = 17,500 * P2.59

Total Cost for Started and Completed = P45,325

25. Total Cost for Work in Process, Ending Inventory:

Total Cost for Work in Process, Ending Inventory = Ending work in process inventory * Total Manufacturing Cost per Unit

Total Cost for Work in Process, Ending Inventory = 2,000 * P2.59

Total Cost for Work in Process, Ending Inventory = P5,180

Answer:

x=4

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

0.75x+3=6(x−3)

0.75x+3=(6)(x)+(6)(−3)(Distribute)

0.75x+3=6x+−18

0.75x+3=6x−18

Step 2: Subtract 6x from both sides.

0.75x+3−6x=6x−18−6x

−5.25x+3=−18

Step 3: Subtract 3 from both sides.

−5.25x+3−3=−18−3

−5.25x=−21

Step 4: Divide both sides by -5.25.

−5.25x/-5.25    =    -21/-5.25

Answer: x=4

The value of x from the given equation is 4.

The given equation is 0.75x + 3 = 6 (x - 3).

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

The given equation can be solve for x as follows:

0.75x + 3 = 6x - 18

⇒ 6x-0.75x = 3+18

⇒ 5.25x=21

⇒ x=21/5.25

⇒ x=4

Therefore, the value of x from the given equation is 4.

The derivative of H(z) is H'(z) = -2zd^2/[(d^2-z^2)(d^2+z^2)].

To differentiate the function H(z) = ln[(d^2-z^2)/(d^2+z^2)]^(1/2), we will use the chain rule and the power rule of differentiation.

First, we can simplify the expression inside the natural logarithm using the laws of exponents:

[(d^2-z^2)/(d^2+z^2)]^(1/2) = [(d^2-z^2)^(1/2)/(d^2+z^2)^(1/2)]

Now we can differentiate H(z) as follows:

H'(z) = d/dz [ln[(d^2-z^2)/(d^2+z^2)]^(1/2)]

= (1/2)[(d^2+z^2)^(1/2)/(d^2-z^2)^(1/2)] * d/dz [(d^2-z^2)/(d^2+z^2)]

Using the quotient rule, we can simplify the derivative:

d/dz [(d^2-z^2)/(d^2+z^2)] = [(2z)(d^2+z^2) - (d^2-z^2)(2z)]/(d^2+z^2)^2

= -4zd^2/(d^2+z^2)^2

Substituting this back into H'(z), we get:

H'(z) = (1/2)[(d^2+z^2)^(1/2)/(d^2-z^2)^(1/2)] * (-4zd^2/(d^2+z^2)^2)

= -2zd^2/[(d^2-z^2)(d^2+z^2)]

Therefore, the derivative of H(z) is:

H'(z) = -2zd^2/[(d^2-z^2)(d^2+z^2)]

Answer:

The average rate of change of the function over the given interval is -6

Step-by-step explanation:

The function we want to find its average rate of change is;

F(x) = 17 - x^2

Mathematically, the average rate of change of a function F(x) over an interval (a,b) can be calculated as;

{F(b) - F(a)}/(b-a)

According to this question, a = 1 and b = 5

F(a) = F(1) = 17 -(1)^2 = 17 -1 = 16

F(b) = F(5) = 17 - 5^2 = 17-25 = -8

So making the substitution; we have

(-8)-16/(5-1) = -24/4 = -6

The average of the sample ranges for the weight of packages of Skittles is 0.11. So, the correct answer is (e) 0.11.

To find the average of the sample ranges for the weight of packages of Skittles, we first calculate the range for each sample. The range is the difference between the maximum and minimum values in each sample.

Sample 1: Range\(= 3.62 - 3.58 = 0.04\)

Sample 2: Range\(= 3.65 - 3.49 = 0.16\)

Sample 3: Range \(= 3.65 - 3.45 = 0.20\)

Sample 4: Range \(= 3.64 - 3.54 = 0.10\)

Sample 5: Range\(= 3.62 - 3.49 = 0.13\)

Next, we calculate the average of these sample ranges:

A\(verage = (0.04 + 0.16 + 0.20 + 0.10 + 0.13) / 5 = 0.11\)
