Step-by-step explanation:

Basically, you find the area of Juan and Matthew's gardens then add them up.  

First let's find the area of Juan's garden.

Area is equal to length times width ([tex]a = lw[/tex])

So you do 16 * 12 which equals 192.

Now let's find the area of Matthew's garden.

So you do 18 * 21 which equals 378.

Then you add up both areas.

192 + 378 = 570

Step-by-step explanation:

Let w = width and h = height. Then we have

w = 3*h - 17

and

4*w + h = 30 (4 shelves and 1 sides).

Plug in the first equation into the second and solve for h:

4*(3*h - 12) + h = 30

12*h - 48 + h = 30

13*h = 78

h = 78/13

h = 6

Plug that in the first equation to find w = 3*6 - 17 = 1

So width = 1 feet.

height = 6 feet

Step-by-step explanation:

Using the Central Limit Theorem, it is found that the condition that applies to this test is:

C. The sample includes at least 30 employees from each department.

It states that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

For a skewed variable, the sampling distribution is also approximately normal, as long as n is at least 30.

From this, since we have a skewed variable, it is found that a sample size of at least 30 is needed, hence option C is correct.

The value of x in the direct and indirect varoation is calculated as: x = 2.

If k is the constant of proportionality among two or more variables (x, y, z), a combined equation of direct and indirect variation is, z = kx/y, if z varies directly with x and indirectly with y.

With the information stated, we would have the following:

z = kx/y³

Find k, by plugging in the values of x, y, and z:

12 = k(8/2³)

12 = k(8/8)

12 = k

k = 12

Find x when y = 1 and z = 24:

24 = 12(x)/1³

24 = 12x

24/12 = x

x = 2.

Therefore, the value of x in the direct and indirect varoation is calculated as: x = 2.

The value of x determined algebraically given the total area of the rectangle is 1.5 inches

Initial dimensions:

Length = 14 inches

Width = 10 inches

New dimensions:

Length = 14 + x

Width = 10 + x

Area = 320 square inches

Area of a rectangle = Length × Width

320 = (14 + x) × (10 + x)

320 = 14x × 10x

320 = 140x²

x² = 320/140

Answer:

(7, -1)

Step-by-step explanation:

Let's remember our key words:

Down/up means to translate the y axis.

Right/left means to translate the x axis.

Now that we know what to do, let's look at our equation.

----------------------------------------------------------------------------------------------------------

A point located at (5, 3) is translated down 4 units and right 2 units.

Let's work on the x axis first.

It says that you are translating to the right. That means your value is going higher, so you go to the right 2. 5+2=7

So now that we have our x, (7), let's rewrite our equation. (7, 3)

----------------------------------------------------------------------------------------------------------

Next, let's do y.

The points are translating down. That means our value will lessen.

Since we are going down on our y axis by 4, we will subtract our current y coordinate with 4. 3-4=-1.

Now we know our y, so let's rewrite our equation with our new y. (7, -1).

----------------------------------------------------------------------------------------------------------

Our final coordinates are (7, -1).

Step-by-step explanation:

Step 1: Take the First Derivative This means only differentiate once.

Disclaimer: Since absolute value only take positve outputs and quadratics only take positve outputs, we can get rid of the absolute value signs so we now have

[tex]e {}^{ {x}^{2} - 1 } [/tex]

We have the function x^2-1 composed into the function e^x.

So we use chain rule

Which states the derivative of a function composed is the

derivative of the main function times the derivative of the inside function.

So the derivative of the main function is

[tex] \frac{d}{dx} (e {}^{x} ) = e {}^{x} [/tex]

Then we replace x with x^2-1

[tex]e {}^{ {x}^{2} - 1} [/tex]

Then we take the derivative of the second function which is 2x so qe multiply them

[tex]e { }^{ {x}^{2} - 1 } 2x[/tex]

Step 2: Set the equation equal to zero.

[tex]e {}^{x {}^{2} - 1} 2x = 0[/tex]

Since e doesn't reach zero. We can just set 2x=0.

[tex]2x = 0 = x = 0[/tex]

So the critical point is 0.

Since e^x will never reach zero

Since 0 is the only critical point, this where the max or min will occur at.

Next we pick any numbergreater than zero, and plug them in the derivative function which gives us a positve number.

Any pick less than zero will give us a negative number.

Since the function is decreasing then increasing, we have a minimum.

Since 0 is the only critical point, we have a absolute minimum at 0.

To find the y coordinate, plug 0 in the orginal function.

Which gives us

[tex]e {}^{ {0}^{2} - 1 } = e {}^{ - 1} = \frac{1}{e} [/tex]

So the minimum occurs at

(0,1/e).

A permutation is an act of correctly arranging things or pieces. Combinations are a method of taking stuff or pieces from an assortment of items or sets in which the order of the items is irrelevant.

The number of contestants is 210.

⇒ ²⁰⁹C₁

⇒ ²⁰⁸C₁

⇒ 208

Then the total number of ways of contestants can win first, second, and third prizes will be

⇒ 210 x 209 x 208

Answer:

Smith should use 900 minute plan and Jones should use 1500 minute plan

Step-by-step explanation:

There are best answers

1. Equations/Inequalities for Each Plan:

Plan A: Cost = $39.99 + 0.25 * (m - 450), m ≤ 450

Plan B: Cost = $59.99 + 0.30 * (m - 900), m ≤ 900

Plan C: Cost = $99.99 + 0.35 * (m - 1500), m ≤ 1500

2. Best Plan for Customers:

Customer Smith (750 min): Plan B ($59.99)

Customer Jones (1350 min): Plan C ($84.99)

3. For both customers, Plan B offers the best value for 750 minutes, while Plan C is optimal for 1350 minutes due to its lower cost per minute overages.

4. Plan A is the least cost-effective for both. The chosen plans reflect the importance of base minutes and overage charges.

1. Equations/Inequalities for Each Plan:

Let's denote the number of minutes used as "m."

Plan A:

Cost: $39.99 for 450 minutes, then $0.25/minute for each additional minute.

Equation: Cost = $39.99 + 0.25 * (m - 450), if m > 450

Inequality: m ≤ 450

Plan B:

Cost: $59.99 for 900 minutes, then $0.30/minute for each additional minute.

Equation: Cost = $59.99 + 0.30 * (m - 900), if m > 900

Inequality: m ≤ 900

Plan C:

Cost: $99.99 for 1500 minutes, then $0.35/minute for each additional minute.

Equation: Cost = $99.99 + 0.35 * (m - 1500), if m > 1500

Inequality: m ≤ 1500

2. Determine the Best Plan for Customers:

Let's evaluate the cost for both customers using the given plans:

Customer Smith:

Usage: 750 minutes

Plan A: Cost = $39.99 + 0.25 * (750 - 450) = $112.49

Plan B: Cost = $59.99

Plan C: Cost = $99.99

Best Plan: Plan B ($59.99)

Customer Jones:

Usage: 1350 minutes

Plan A: Cost = $39.99 + 0.25 * (1350 - 450) = $297.49

Plan B: Cost = $59.99 + 0.30 * (1350 - 900) = $374.99

Plan C: Cost = $99.99 + 0.35 * (1350 - 1500) = $84.99

Best Plan: Plan C ($84.99)

3. Explanation and Recommendation:

Customer Smith's usage of roughly 750 minutes falls within the range of Plan B's base minutes (900) and is more cost-effective with Plan B. However, for Customer Jones, who uses around 1350 minutes, Plan C offers a lower overall cost due to its higher base minutes (1500). Plan A is the least cost-effective option for both customers due to its lower base minutes and higher per-minute charges.

4. Summary for Employees:

Dear Team,

When assisting customers with choosing a cell phone plan, please consider the following options:

Plan A: $39.99 for 450 minutes, then $0.25/minute.

Plan B: $59.99 for 900 minutes, then $0.30/minute.

Plan C: $99.99 for 1500 minutes, then $0.35/minute.

For customers using around 750 minutes per month, recommend Plan B for its competitive pricing. For customers using around 1350 minutes, advise them to opt for Plan C to optimize cost efficiency. Always ensure to guide customers toward the most suitable plan based on their usage patterns.

Thank you for your dedication to excellent customer service.
