To calculate the company's annual holding cost, we need to multiply the annual average inventory by the holding cost per unit.

First, we need to calculate the annual average inventory. The formula for the average inventory is (Q/2), where Q represents the order quantity.

Given:

Annual requirements (Demand) = 7500 units

Ordering cost = BD 12

Order quantity (Q) = 150, 300, 45000 (Assuming these are different order quantities)

Holding cost per unit = BD 0.5

For each order quantity, we can calculate the annual average inventory using the formula (Q/2). Then, we multiply the average inventory by the holding cost per unit.

For order quantity Q = 150:

Average Inventory = Q/2 = 150/2 = 75 units

Holding Cost = Average Inventory * Holding cost per unit = 75 * 0.5 = BD 37.5

For order quantity Q = 300:

Average Inventory = Q/2 = 300/2 = 150 units

Holding Cost = Average Inventory * Holding cost per unit = 150 * 0.5 = BD 75

For order quantity Q = 45000:

Average Inventory = Q/2 = 45000/2 = 22500 units

Holding Cost = Average Inventory * Holding cost per unit = 22500 * 0.5 = BD 11250. Now, we sum up the holding costs for each order quantity:

Annual Holding Cost = BD 37.5 + BD 75 + BD 11250 = BD 11362.5 Therefore, the company's annual holding cost is BD 11362.5.

In this question we have,

The population mean μ = 1.00

The sample size n = 49

The sample mean X = 1.06

The standard deviation σ = 0.22cm

The significance level α = 0.10

So, the hypothesis is:

The null hypothesis: H0: μ = 1

The alternative hypothesis: Ha: μ ≠ 1

Thus, the test statistic value is,

z = (X - μ)/(σ/√n)

= (1.06 - 1)/(0.22/√49)

= 0.06 / 0.03142

= 1.91

So, for z = 1.91, the p-value is 0.028067.

The method applied for determining the density of a solid (regular and irregular) and a liquid is based on the concept of mass and volume.

For solids (regular and irregular):

Determining the mass: The mass of the solid can be measured using a balance or scale. The unit of mass is typically grams (g) or kilograms (kg).

Determining the volume:

Regular solids: The volume of regular solids, such as cubes or rectangular prisms, can be calculated using their geometric formulas. For example, the volume of a cube is calculated by cubing the length of one of its sides: Volume = side length^3.

Irregular solids: The volume of irregular solids can be determined using various methods such as water displacement. The solid is immersed in a known volume of liquid (e.g., water), and the increase in the volume of the liquid is measured. This increase represents the volume of the solid.

Calculating the density: The density of a solid is calculated by dividing its mass by its volume. The unit of density is typically grams per cubic centimeter (g/cm^3) or kilograms per cubic meter (kg/m^3).

For liquids:

Determining the mass: Similar to solids, the mass of the liquid can be measured using a balance or scale.

Determining the volume: The volume of a liquid can be measured directly using a graduated cylinder or other volumetric measuring devices. The unit of volume is typically milliliters (mL) or liters (L).

Calculating the density: The density of a liquid is calculated by dividing its mass by its volume. The unit of density is typically grams per milliliter (g/mL) or kilograms per liter (kg/L).

The method for determining the density of a solid (regular and irregular) involves measuring the mass and volume of the solid and calculating the density by dividing the mass by the volume. For liquids, the density is determined similarly by measuring the mass and volume.

The US government recommends low dose x-ray or dual-energy x-ray absorptiometry (DEXA) screening for women aged 65 years and older to check for osteoporosis. Osteoporosis is a condition that weakens bones, making them more likely to break. The suggested screening interval for low dose x-ray or DEXA is every two years. However, this may vary based on individual risk factors such as family history of osteoporosis, use of certain medications, and history of fractures.
Women who are at higher risk of developing osteoporosis may need more frequent screenings. For example, women with a history of fractures or those who have taken certain medications for a prolonged period may need more frequent screenings. It is important to discuss individual risk factors with a healthcare provider to determine the appropriate screening interval.
It is also important to note that while low dose x-ray or DEXA is recommended for women aged 65 years and older, women who are younger and have risk factors for osteoporosis may also need screening. Some of these risk factors include a family history of osteoporosis, low body weight, smoking, and certain medical conditions such as rheumatoid arthritis.

The percent of Hispanics that prefer to read catalogs in Spanish is equal or higher than 30%

What is percentage ?

A percentage is a figure or ratio stated as a fraction of 100 in mathematics. Although the abbreviations "pct.", "pct.", and occasionally "pc" are also used, the percent symbol, "%," is frequently used to indicate it. A % is a number without dimensions and without a standard measurement.

%, which is a relative figure used to denote hundredths of any quantity. Since one percent (symbolized as 1%) is equal to one hundredth of something, 100 percent stands for everything, and 200 percent refers to twice the amount specified.

By dividing the value by the entire value and multiplying the result by 100, one may determine the percentage. The percentage calculation formula is (value/total value)100%.

The probability of getting three tails in a row is 1/8 or 0.125,

A probability is a number that reflects the chance or likelihood that a particular event will occur. Probabilities can be expressed as proportions that range from 0 to 1, and they can also be expressed as percentages ranging from 0% to 100%

The probability of getting three tails in a row when flipping a fair coin (assuming the coin is unbiased and has an equal chance of landing on heads or tails) is:

P(three tails) = (1/2)³ = 1/8 = 0.125

Here, (1/2) represents the probability of getting tails on a single coin flip. Since we need to get tails on three consecutive coin flips, we multiply this probability by itself three times, giving us (1/2)³.

Therefore, the probability of getting three tails in a row is 1/8 or 0.125, which means there is a 12.5% chance of getting three tails when flipping a coin three times in a row.

Answer:

The numbers at 13 and 13

Step-by-step explanation:

The two numbers in question are equal, and if their sum is 26, then they must be 13 and 13.

The two numbers are (13, 13).

Given that,

The sum of the two numbers is 26.

And the sum of their square is minimum.

We have to determine,

The two numbers are.

According to the question,

Let, the first number be x,  

and the second number be y.

The sum of the two numbers is 26.

\(x + y = 26\)

And The sum of their squares is a minimum.

\(x^2 + y^2 = h\)

Solving both the equation,

\(x + y = 26\\\\x = 26-y\)

Substitute the value of x in equation 2,

\(x^2 + y^2 = h\\\\(y-26)^2 + y^2 = h \\\\y^2 + 676 -52y + y^2 = h\\\\2y^2 -52y + (676-h) = 0\)

Then, The vertex of the parabola is,

\(\dfrac{-b}{2a} = \dfrac{-(-52)}{2(2)} = \dfrac{52}{4} = 13\)

The minimum value of the parabola is 13, which is also the sum of squares.

Therefore, The two number is x = 13 and y =13.

Step-by-step explanation:

Sinusoid Function

The cosine and sine functions are generally called sinusoids because of their characteristic oscillatory behavior.

The general cosine function is expressed as

\(y(x)=A\cos(\omega x+\phi)+B\)

Where A is the amplitude, ω is the angular frequency, Ф is the phase shift and B is the midline or vertical shift.

We are given the function:

\(f(x)=3\cos(\pi x)-2\)

The coefficient of x is the angular frequency, thus

\(\omega=\pi\)

Since

\(\omega=2\pi f\)

Where f is the frequency, then

\(2\pi f=\pi\)

Simplifying:

\(f=\frac{1}{2}\)

A: y= 3x-4

B: y= -2/4x+3

Step-by-step explanation:

slope intercept form: y=mx+b

m = slope

slope = rise/run

b = y-intercept

Answer:

A: y = 3x - 4

B: y = -1/2x +3

Step-by-step explanation:

First, lets find the slope of line B. We need to find two coordinates on the line that coincide with points on the grid. We see that (2, 2) and (4, 1) are two points that match the criteria, so we can use both points. You can use any two points, I just randomly chose these two. Slope is nothing but the Y coordinate of the first point  subtracted from the Y coordinate of the second point. We do 2 - 4 and get -2. Next, we do the same thing but with the X coordinates to get 2 - 1, which is 1. We do 1 over -2 to get negative 1/2 for our slope. The last variable in the equation is just where the line hits the Y axis, which is 3. So, the final equation is y = -1/2x + 3. Rinse and repeat for the next question.

The directional derivative of f at the point (3,-1) in the direction of the vector v=2i+5j is

18/sqrt(29).

To find the directional derivative of the function f(x,y)=2x^2y^3-6y at the point (3,-1) in the direction of the vector v=2i+5j:

We first need to find the unit vector in the direction of v.

To do this, we divide v by its magnitude:

||v|| = sqrt(2^2 + 5^2) = sqrt(29)

So,

u = v/||v|| = (2/sqrt(29))i + (5/sqrt(29))j

Now we can use the formula for the directional derivative:

D_u(f) = ∇f · u

where ∇f is the gradient of f.

To find ∇f, we take the partial derivatives of f with respect to x and y:

∂f/∂x = 4xy^3

∂f/∂y = 6x^2y^2 - 6

So,

∇f = (4xy^3)i + (6x^2y^2 - 6)j

Plugging in the point (3,-1) and the unit vector u,

we get:

D_u(f) = ∇f · u = (4(3)(-1)^3)(2/sqrt(29)) + (6(3)^2(-1)^2 - 6)(5/sqrt(29))

= -12/sqrt(29) + 30/sqrt(29)

= 18/sqrt(29)

Therefore, the directional derivative of f at the point (3,-1) in the direction of the vector v=2i+5j is 18/sqrt(29).

The price elasticity of demand, when using the midpoint​ formula, would be B.1.29.

How to find the price elasticity of demand ?

Price elasticity of demand = ((Q2 - Q1) / ((Q2 + Q1) / 2)) / ((P2 - P1) / ((P2 + P1) / 2))

where:

Q1 = initial quantity demanded = 20 units

Q2 = final quantity demanded = 15 units

P1 = initial price = $8

P2 = final price = $10

Substituting the values:

Price elasticity of demand = ((15 - 20) / ((15 + 20) / 2)) / (($10 - $8) / (($10 + $8) / 2))

= (-5 / 17.5) / (2 / 9)

To solve for the sum and difference of complex numbers in polar form, we can add or subtract their magnitudes and their angles separately.

Given:

a = 3.1∠63.2°

b = 6.6∠26.2°

To find a + b:

We can use the formula for adding complex numbers in polar form:

(a + b) = (3.1∠63.2°) + (6.6∠26.2°)

       = (3.1 cos 63.2° + 6.6 cos 26.2°) + j(3.1 sin 63.2° + 6.6 sin 26.2°)

       ≈ 6.94∠37.4°

Therefore, a + b = 6.94∠37.4°.

To find a - b:

We can use the formula for subtracting complex numbers in polar form:

(a - b) = (3.1∠63.2°) - (6.6∠26.2°)

       = (3.1 cos 63.2° - 6.6 cos 26.2°) + j(3.1 sin 63.2° - 6.6 sin 26.2°)

       ≈ -3.78∠141.5°

Graph F best represents the function.

The correct graph F is also attached below.

Step-by-step explanation:

Given the function

f(x) = 2(5)ˣ

We know that the value of the y-intercept can be determined by setting x = 0 and determining the corresponding value of y.

so substituting x = 0 in the function

y = 2(5)ˣ

y = 2(5)⁰

y = 2(1)      ∵ (5)⁰ = 1

y = 2

Thus, the y-intercept is (0, 2)

Let us check another point

now substitute x = 1

y = 2(5)ˣ

y = 2(5)¹

y = 10

Thus, the value of y = 10 at x = 1

So, we have to two points:

Now, if we carefully observe, we can easily figure out that the graph F represents the function f(x) = 2(5)ˣ.

Because the graph F has a y-intercept (0, 2) and also the point (1, 10) is validating the graph.

Therefore, graph F best represents the function.
