The maximum length of each prism is equal to 7.99 centimeter.

Maximum surface area = 275 square centimeter (cm²).

Given, Light fixtures of regular hexagonal prism .

Determine the maximum surface area of this regular hexagonal prism by using this mathematical expression:

Maximum surface area (quantity) = Cost/unit price

Maximum surface area (quantity) = $11/$0.04

Maximum surface area (quantity) = 275 square centimeter (cm²).

Mathematically, the surface area of a regular hexagonal prism can be calculated by using this formula:

\(A = 6al + 3\sqrt{3} a^2\)

Where:

A represents the surface area of a regular hexagonal prism.

a represents the edge length (apothem) of a regular hexagonal prism.

l represents the length of a regular hexagonal prism.

Substituting the given parameters into the formula, we have;

\(275 = 6 \times 4l + (3\sqrt{3} \times 4^2)\)

\(275 = 24l + 48\sqrt{3} \\24l = 275 - 48\sqrt{3}\\ 24l = 191.8616\\l = 191.8616/24\)

Length, l = 7.99 centimeter.

Answer:

0 ≤ x ≤ 2 (i assumed that the arrows included 0 and 2).

Step-by-step explanation:

One arrow shows 0 and greater (as it is pointing right) and the other shows 2 and smaller (as it is pointing left). The arrow pointing right has the equation of:

x ≥ 0 (where x is a random number)

The arrow pointing left has the equation of:

x ≤ 2 (where x is a random number)

Assuming that you need to find an equation so that x fits both inequalities, we combine them into one inequality and get:

0 ≤ x ≤ 2

Answer:

To find out how much more Joi paid than Adelyn for each fidget popper, we need to know how much Adelyn paid for each fidget popper.

If we assume that Adelyn bought the same set of fidget poppers as Joi at the regular price of $20 without tax, then we can calculate how much Adelyn paid for each fidget popper by dividing the total price by the number of fidget poppers in the set.

Let’s say that there are 10 fidget poppers in the set. Then, Adelyn paid $20 / 10 = $2 per fidget popper.

Joi bought the same set of fidget poppers at the regular price of $20 plus 8% sales tax. To find out how much Joi paid for each fidget popper, we can add the sales tax to the regular price and then divide by the number of fidget poppers in the set.

The sales tax is 8% of $20, which is $1.60. So, Joi paid a total of $20 + $1.60 = $21.60 for the set.

If there are 10 fidget poppers in the set, then Joi paid $21.60 / 10 = $2.16 per fidget popper.

To find out how much more Joi paid than Adelyn for each fidget popper, we can subtract Adelyn’s price per fidget popper from Joi’s price per fidget popper:

$2.16 - $2 = $0.16

Therefore, Joi paid $0.16 more than Adelyn for each fidget popper

The value of the argument of z is -π/3.

The angle that the line from Ф, z to the origin creates with the positive direction of the real axis is known as the argument of z is Ф, and it is variously represented by the symbols arg ( z ), (z) or Ф. Because it is an argument of z is Ф, then 2 nπ + Ф is likewise a valid argument, the argument of z can take on any number of conceivable values.

We define a singular value known as the major argument of z to be more precise.

Given z = 1/16 - √3/16i

equation of z is x + iy

here x = 1/16 and y = -√3/16

to find the angle,

tanФ = y/x

tanФ = (-√3/16)/(1/16)

tanФ = -√3

Ф = tan⁻¹(-√3)

Ф = -π/3

Hence  arguement of z is -π/3.

Answer:

4y-12

Step-by-step explanation:

To multiply a sum (or difference) by a factor, each summand (or minuend and subtrahend) is multiplied by this factor and the resulting products are added (or subtracted).

If the operation outside the parentheses (in this case, the multiplication) is commutative, then left-distributivity implies right-distributivity and vice versa, and one talks simply of distributivity.

The equivalent value of the expression is A = 4y - 12

Given data ,

Let the equation be represented as A

Now , the value of A is

A = 4 ( y - 3)

On simplifying the equation , we get

A = 4 ( y - 3 )

So , the left hand side of the equation is equated to the right hand side by the value of A = 4 ( y - 3 )

Opening the parenthesis on both sides , we get

A = 4 ( y - 3 )

Using the distributive property , we get

A = 4 ( y ) - 4 ( 3 )

On further simplification , we get

A = 4y - 12

Taking the common factor as 4 , we get

A = 4 ( y - 3 ) = 4y - 12

Therefore , the value of A = 4y - 12

Hence , the expression is A = 4y - 12

if f(1) = 10 and 2 ≤ f ′ (x) ≤ 5 for all x, The smallest possible value of f(4) is 16.

Using the Mean Value Theorem, we can find a lower bound for f(4) based on the given information. By the Mean Value Theorem, there exists some c between 1 and 4 such that:

f'(c) = (f(4) - f(1))/(4 - 1) = (f(4) - 10)/3

Since 2 ≤ f ′ (x) ≤ 5 for all x, we have:

2 ≤ f'(c) ≤ 5

Substituting the expression we obtained for f'(c), we get:

2 ≤ (f(4) - 10)/3 ≤ 5

Multiplying through by 3, we get:

6 ≤ f(4) - 10 ≤ 15

Adding 10 to each term, we get:

16 ≤ f(4) ≤ 25

An ordered pair is a solution of an equation in two variables if replacing the variables by the coordinates of the ordered pair results in a true statement.

In mathematics, an equation in two variables represents a relationship between two quantities. An ordered pair consists of two values, typically denoted as (x, y), that represent the coordinates of a point in a two-dimensional plane.

When these values are substituted into the equation, if the equation holds true, then the ordered pair is considered a solution or a solution set to the equation. This means that the relationship described by the equation is satisfied by the values of the ordered pair. In other words, the equation is true when evaluated with the values of the ordered pair.

False. When performing regression analysis, different samples will not necessarily yield the same sample regression line.

This is because the sample regression line is based on the specific data points in the sample, and different samples may have different data points that can lead to different regression lines. However, if the samples are representative of the same population and the relationship between the variables is consistent, the regression lines may be similar. The term "content loaded" does not apply to this question.

There are 1296 ways the promoter can select which cans to use for the taste test.

To solve this problem, we can use the concept of combinations.

First, let's determine the number of ways to select 2 cans of Diet Coke from the 9 available cans. We can use the combination formula, which is nCr = n! / (r! * (n-r)!), where n is the total number of items and r is the number of items to be selected. In this case, n = 9 and r = 2.

Using the combination formula, we have:
9C2 = 9! / (2! * (9-2)!) = 9! / (2! * 7!) = (9 * 8) / (2 * 1) = 36

Therefore, there are 36 ways to select 2 cans of Diet Coke from the 9 available cans.

Similarly, there are also 36 ways to select 2 cans of Coke Zero from the 9 available cans.

To find the total number of ways the promoter can select which cans to use for the taste test, we multiply the number of ways to select 2 cans of Diet Coke by the number of ways to select 2 cans of Coke Zero:

36 * 36 = 1296

The graph of the linear equation, 5x - 9y = -7, is in the attachment below.

The linear equation that models a graph can be written in  slope-intercept equation as y = mx + b. The value of the slope, which is the rise over the run of the line is represented as m, while the value of b, which is where the line intercepts the y-axis is b.

Given the linear equation, 5x - 9y = -7, rewrite in slope-intercept form:

5x - 9y = -7

-9y = -5x - 7

-9y/-9 = -5x/-9 - 7/-9

First, let us calculate the forecast for week 7. The naïve method (most recent value) is used to make the forecast. The most recent value is 15, so the forecast for the next week, which is week 7, is 15.

Using the naïve method as the forecast for the next week, the following measures of forecast accuracy are calculated.The given data is as follows:

Week 1 2 3 4 5 6Value 19 13 16 10 18 15.

Now we will calculate the Mean absolute error:

Mae = (19-13)+(13-16)+(16-10)+(10-18)+(18-15) / 5=6+3+6+8+3 / 5=6.4.

Therefore, the Mean absolute error is 6.4.

Mean squared error can be calculated as follows:

Mse = [(19-13)²+(13-16)²+(16-10)²+(10-18)²+(18-15)²] / 5=196 / 5=39.2.

Therefore, the Mean squared error is 39.2.

Now let us calculate Mean absolute percentage error:

Map = [ (6/19) + (3/13) + (6/16) + (8/10) + (3/18) ] / 5= 0.962.

Therefore, the Mean absolute percentage error is 0.96.
