(a)The optimal order quantity is  4609 units.

(b)The time between orders is  1.98 months.

To determine the optimal order quantity and the approximate time between orders, the Economic Order Quantity (EOQ) model. The EOQ model minimizes the total cost of inventory by balancing ordering costs and carrying costs.

Optimal Order Quantity:

The formula for the EOQ is given by:

EOQ = √[(2DS) / H]

Where:

D = Annual demand

S = Cost per order

H = Holding cost per unit per year

calculate the annual demand (D) using the 2020

sales numbers provided:

D = 651 + 808 + 514 + 174 + 435 + 426 + 687 + 582 + 662 + 1551 + 1295 + 1774

= 9559 units

To calculate the cost per order (S) and the holding cost per unit per year (H).

The cost per order (S) is given as $500.

The holding cost per unit per year (H)  calculated as follows:

H = Carrying cost percentage × Unit value

= 0.30 × $3

= $0.90

substitute these values into the EOQ formula:

EOQ = √[(2 × 9559 × $500) / $0.90]

= √[19118000 / $0.90]

≈ √21242222.22

≈ 4608.71

Approximate Time Between Orders:

To calculate the approximate time between orders, we'll divide the total number of working days in a year by the number of orders per year.

Assuming 360 days in a year and a lead time of 1 week (7 days) for shipping, we have:

Working days in a year = 360 - 7 = 353 days

Approximate time between orders = Working days in a year / Number of orders per year

= 353 / (9559 / 4609)

= 0.165 years

Converting this time to months:

Approximate time between orders (months) = 0.165 × 12

= 1.98 months

Answer:

x        -6         3        15       -12

y        11         5         -3        15

Step-by-step explanation:

Domain of a function represents the set of x-values (input values) and y-values (output values) of the function represent the Range of the function.

Given function is,

\(y = -\frac{2}{3}x +7\)

If Domain (input values) of this function is,

{-12, -6, 3, 15}

Table for the input-output values of this function,

x        -6         3        15       -12

y        11         5         -3        15

To determine the point(s) at which the given function f(x) is continuous, we need to use the definition of continuity which is: A function is said to be continuous at a point a in its domain if the following three conditions are met:

1. f(a) is defined;

2. lim x → a f(x) exists; 3. lim x → a f(x) = f(a).By using this definition, we can determine the set of x-values where the function is continuous.To determine where the function is continuous, we must first find the values of x that make the function undefined. The function will be undefined when the denominator equals zero, which is when x = 6. So, we cannot include the value of 6 in our interval notation to describe the set of x-values where the function is continuous.

Now, we need to determine if the function is continuous to the left and right of x = 6 using the definition of continuity. Let's consider the left side of x = 6. We need to find if the limit exists and if it equals f(6).lim x → 6- f(x) = lim x → 6- (14 /(x - 6)) - 5x = ∞Since the limit does not exist as x approaches 6 from the left, the function is not continuous to the left of x = 6.Let's consider the right side of x = 6. We need to find if the limit exists and if it equals f(6).lim x → 6+ f(x) = lim x → 6+ (14 /(x - 6)) - 5x = -∞Since the limit does not exist as x approaches 6 from the right, the function is not continuous to the right of x = 6.

Since the function is not continuous to the left or right of x = 6, we can describe the set of x-values where the function is continuous using interval notation. The set of x-values where the function is continuous is: (-∞, 6) U (6, ∞).

In this question, we were required to determine the point(s) at which the given function f(x) is continuous. For this purpose, we used the definition of continuity which states that a function is continuous at a point a in its domain if f(a) is defined, the limit x→a f(x) exists, and lim x → a f(x) = f(a).By using this definition, we found that the function will be undefined when the denominator equals zero, which is when x = 6. So, we cannot include the value of 6 in our interval notation to describe the set of x-values where the function is continuous.

Furthermore, we considered the left side of x = 6 and the right side of x = 6 separately to determine if the limit exists and if it equals f(6). We found that the limit does not exist as x approaches 6 from the left and right, so the function is not continuous to the left or right of x = 6.As a result, we concluded that the set of x-values where the function is continuous is (-∞, 6) U (6, ∞), which means that the function is continuous for all values of x except x = 6.

The right response is that the two linear equation never intersect , because the graph of these two linear equation will be two parallel lines.

How many types of solution are there for two linear equations ?

There are 2 types of solution :
Consistent :

A consistent system is said to be an independent system if it has a single solution.

A consistent system is said to be a dependent system if the equations have the same slope and the same y-intercepts. In other words, the lines coincide, so the equations represent the same line. Each point on the line represents a pair of coordinates that fits the system. So there are an infinite number of solutions.

Non-consistent :

Another type of system of linear equations is the inconsistent system, in which the equations represent two parallel lines. The lines have the same slope and different y-intercepts. There are no common points for both lines; therefore, there is no solution to the system and if we draw the graph of these equations then the graphs of both equation becomes parallel to each other.

The two linear equations never intersect.

When a system of two linear equations in two variables has no solution, it means that there is no set of values for the variables that satisfies both equations simultaneously. Geometrically, this corresponds to the two lines represented by the equations being parallel. Since parallel lines never intersect, the statement "The two linear equations never intersect" accurately describes the situation.

If the two linear equations were graphed on a coordinate plane, they would appear as two distinct lines that run parallel to each other without ever crossing or intersecting. This indicates that there is no common point of intersection between the lines, and therefore no solution exists for the system of equations.

It is important to note that this scenario is different from the case where the two linear equations represent the same line. In that case, the equations would be equivalent, and every point on the line would satisfy both equations. However, when there is no solution, it means that the lines do not share any common points and never intersect.

If a certain pregnancy had a z-score of -2.5 with mean 266 days and standard deviation 16 days , the pregnancy lasted 230 days.

We know that the length of human pregnancies can be modeled by a normal distribution with a mean of 266 days and a standard deviation of 16 days.

We are also given that a certain pregnancy had a z-score of -2.5. The z-score is a measure of how many standard deviations a data point is away from the mean. A negative z-score means that the data point is below the mean.

We can use the formula for converting a z-score to an actual value in a normal distribution:

z = (x - mu) / sigma

where z is the z-score, x is the actual value we want to find, mu is the mean, and sigma is the standard deviation.

Plugging in the given values, we get:

-2.5 = (x - 266) / 16

Solving for x, we get:

x = (-2.5 * 16) + 266 = 230

we have proven that:  1 + tanh(x)/(1 - tanh(x)) = e^(2x)

We can start by manipulating the left-hand side of the equation using the identity:

tanh(2x) = (2tanh(x))/(1+tanh²(x))

We have:

1 + tanh(x)/(1 - tanh(x))

= (1 - tanh(x) + tanh(x) + tanh²(x))/(1 - tanh²(x))

= (1 + tanh²(x))/(1 - tanh²(x))

= 1/cosh²(x)

= sech²(x)

Now, we can use the identity:

sech²(x) = 1/(cosh²(x)) = e^(-2x)

to get:

1 + tanh(x)/(1 - tanh(x)) = e^(2x)

Multiplying both sides by 1 - tanh(x), we get:

1 + tanh(x) = e^(2x) - tanh(x)e^(2x)

Adding tanh(x) to both sides, we get:

1 + 2tanh(x) = e^(2x) + tanh(x)e^(2x)

Factoring out tanh(x), we get:

1 + tanh(x)(2 - e^(2x)) = e^(2x)

Dividing both sides by 2 - e^(2x), we finally obtain:

(1 + tanh(x))/(1 - tanh(x)) = e^(2x)

Therefore, we have proven that:

1 + tanh(x)/(1 - tanh(x)) = e^(2x)

Step-by-step explanation:

x =  7      hous worked by Lillian

y  = 6      hours worked by Jacob

Step-by-step explanation:

Let call  " x  "  and  "  y  "  numbers of hours Lillian and Jacob worked respectively, then according to problem statement we have:

They both combined a total of 13 hours, therefore

x  +  y  =  13    ⇒   y  = 13  -  x

And the number of ironed shirts was  295  then we have

25*x  +  20*y  =  295

We need to solve that system of equations for   x     and    y   then

25*x   +  20 * ( 13 - x ) = 295

25*x   +  260  -  20*x   =  295

5*x  =  295  -  260

5*x  =  35

x  = 35/5

x  =  7

And  y  =  13  -  x    ⇒   y  =  13 - 7

y  =  6

The probability of the spinner landing on the letter C is 1/4

To understand the probability of the spinner landing on the letter C, we need to start by looking at the total number of possible outcomes. In this case, there are four possible outcomes, corresponding to the four letters A, B, C, and D.

Since each of the four quadrants on the spinner is equal in size, each of the four letters has an equal chance of being landed on. Therefore, the probability of the spinner landing on the letter C is the number of ways that the spinner can land on C, divided by the total number of possible outcomes.

Since there is only one way for the spinner to land on C, and there are four possible outcomes in total, the probability of the spinner landing on the letter C is 1/4
