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

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.

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).

I hope this helps!

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 IQR for these data is 6.25.

Answer choice A is correct.

An interquartile range is a measure of the difference between the upper and lower quartiles of a dataset.

W can find the values of the upper and lower quartile and median from a box plot.

The middle line is the median and the first line is the lower quartile and the last line is the upper quartile.

The formula used is Upper quartile - Lower quartile.

We have,

To find the IQR, we first need to find the first and third quartiles.

First, we need to order the data from smallest to largest:

10.5, 11, 11.5, 14.5, 14.5, 17, 17, 18, 19

Next, we find the median (middle value) of the data set.

Since we have an odd number of data points, the median is the middle number, which is 14.5.

To find the first quartile (Q1), we need to find the median of the lower half of the data set.

That is, we need to find the median of 10.5, 11, 11.5, and 14.5.

The median of this subset is (11 + 11.5) / 2 = 11.25.

To find the third quartile (Q3), we need to find the median of the upper half of the data set.

That is, we need to find the median of 17, 17, 18, and 19.

The median of this subset is (17 + 18) / 2 = 17.5.

Now we have the first quartile (Q1) = 11.25 and the third quartile (Q3) = 17.5. The IQR is the difference between Q3 and Q1:

IQR = Q3 - Q1

= 17.5 - 11.25

= 6.25

Therefore,

The IQR for these data is 6.25.

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

x² = 2.28571428571428

x = √2.28571428571428

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

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.
