The unit rate of computers per day using the graph is that 12 computers are made per day.

The unit rate is how many units of quantity correspond to the single unit of another quantity. We say that when the denominator in rate is 1, it is called unit rate. Unit rates is said to be the amount of something in each unit or per unit.

To obtain the unit rate of computers sold per day using the graph, we need to obtain the slope of the graph, which is the change in y per change in x

So, it is given by:

\(\text{Slope} = \dfrac{\text{change in y}}{\text{change in x}}\)

\(\text{Slope} = \dfrac{\text{y}_2-\text{y}_1}{\text{x}_2-\text{x}_1}\)

\(\text{y}_2 = 60 , \ \text{y}_1 = 36 , \ \text{x}_2 = 5, \ \text{x}_1 = 3.\)

\(\text{Slope} = \dfrac{(60 - 36)}{(5 - 3)} = \dfrac{24}{2} = 12\)

\(\bold{Slope = 12}\)

Unit rate = 12 computers per day.

The attachment of the graph is given below.

Therefore, the unit rate of computers per day is 12.

Step-by-step explanation:

Start by subtracting 5.2 from both sides of the equation

  so  "subtraction property of equality "    I suppose ......

then the next step would be divide both sides by 2.5  

  which would be division property of equality  

Answer: Subtraction Property of Equality

Step-by-step explanation:

- the subtraction property of equality is the rule that when you subtract the same number to or from both sides of an equation and get an equivalent equation

__________________________________________________________

- for this equation you would subtract 5.2 from the left-side of the equation and subtract it from 35.2 on the right side of the equation

      - this is to isolate n

- basically 2.5n = 30 since n is a variable and that number multiplied by 2.5 will equal 30

- so the new equation would be 2.5n = 30

- so then:  \(\frac{n}{2.5}\) = \(\frac{30}{2.5}\)  so n = 12

To accurately determine the amount they would have to buy, we would need the specific measurements of the pool, the desired fence height and any other requirements they have.

To determine how much Gwen and Lisa would have to buy to replace the fence on their pool, we would need more specific information about the pool's dimensions, the type of fence they want, and any other relevant details.

Let's consider some factors that could affect the amount they would need to purchase:

Perimeter of the pool:

The length of the fence required would depend on the perimeter of the pool.

If we know the dimensions of the pool, we can calculate its perimeter by adding up the lengths of all sides.

Fence height:

The height of the fence is another important factor. Depending on local regulations or personal preferences, Gwen and Lisa might need a specific height for their pool fence.

This would determine the length of fencing material they need to purchase.

Fence type and style:

Different types of fences, such as chain-link, wood, vinyl, or wrought iron, have varying costs and installation requirements.

The choice of fence material and style will impact the amount they would have to buy.

Gates and openings:

If Gwen and Lisa require gates or openings in the fence, they would need to account for these as well.

The number and size of gates would affect the total amount of fencing material needed.

With these details, we can calculate the perimeter, account for gates and openings and factor in the material type and style to provide an estimate of the amount of fencing they need to purchase.

Answer:

There appears to be some part of the question missing. Assuming it asks about the volume, the volume is:

Step-by-step explanation:

The volume of a right rectangular prism may be calculated using the formula:

whl, where w is width, h is height and l is length.

In this case it is hlw or (5.8*14.5*3.5) = 294.35 cubic inches.

Answer: 8 ft

Step-by-step explanation:To find the correct answer, use the formula, V=l×w×h. Substitute 48 for the volume, 2 for width, and 3 for height. Then, use a related division equation to find the length.

48 = l × 2 × 3

48 = l × 6, so 48 ÷ 6 = l

8 = l

The length of the planter box is 8 feet.

Answer:

Graph W

Step-by-step explanation:

The given information describes a radioactive decay process, where the weight of the isotope decreases by half at regular intervals. This type of decay is characteristic of exponential decay.

Based on the description, the graph that represents the weight of the radioactive isotope over time would be a decreasing exponential curve, where the y-axis represents the weight of the isotope (in grams), and the x-axis represents time (in hours).

The initial weight of the isotope is 96 grams, and after each subsequent hour, the weight becomes half of what it was in the previous hour. Therefore, the correct graph would start at 96 grams (the initial weight when x = 0) and then decrease by half every hour. It would be a curve that gets closer and closer to zero but never quite reaches it.

Initial weight: 96 grams

After 1 hour: 96 / 2 = 48 grams

After 2 hours: 48 / 2 = 24 grams

After 3 hours: 24 / 2 = 12 grams

After 4 hours: 12 / 2 = 6 grams

After 5 hours: 6 / 2 = 3 grams

So, the points on the graph would be:

Therefore, the graph that represents the weight of the radioactive isotope over time is Graph W.

According to the concept of compound interest, the effective annual yield on your investment of $1800 at a 6.3% interest rate compounded daily is 6.49%.

To find the effective annual yield, we need to use the formula for compound interest:

A = P(1 + r/n)ⁿˣ

Where A is the amount of money at the end of the investment period, P is the principal amount invested, r is the annual interest rate, n is the number of times the interest is compounded in a year, and t is the number of years.

In this case, we know that the principal amount P is $1800, the annual interest rate r is 6.3%, and the interest is compounded daily, which means that n is 365 (the number of days in a year). We need to find the effective annual yield, which is the total amount of interest earned in one year.

To calculate the effective annual yield, we can use the following formula:

Effective Annual Yield = (1 + r/n)ⁿ - 1

Plugging in the values, we get:

Effective Annual Yield = (1 + 0.063/365)³⁶⁵ - 1

Effective Annual Yield = 0.0649 or 6.49%

b) (3x + 5)(3x + y)

Step-by-step explanation:

First, we can factor out a common factor of 3x from the first two terms:

9x^2 + 3xy = 3x(3x + y)

Now, we can factor out a common factor of 5 from the last two terms:

15x + 5y = 5(3x + y)

Putting it all together, we get:

9x^2 + 3xy + 15x + 5y = 3x(3x + y) + 5(3x + y) = (3x + 5)(3x + y)

The margin of error for a 95% confidence interval for the true proportion of tongue rollers among students is closest to (d) 0.04

The margin of error is a statistic that describes how much random sampling error there is in survey results.

Given in question,

n = 400

p = 317/400

  = 0.7925

Confidence Level = 95%

                          = 0.95

Formula for margin error, E = \(z\sqrt{\frac{p(1-p)}{n} }\)

Confidence level corresponding to 95 % confidence interval, z = 1.96

Therefore,

Margin Error, E = \(1.96\sqrt{\frac{0.7925(1-0.7625)}{400} }\)

                         = 0.0397

                         ≈ 0.04

Area of a square is given by \(\(A_{\text{square}} = s^2\)\), so the area of the square is: \(\[A_{\text{square}} = 9^2 = 81\]\).So, the correct answer is A. 81 square units.Let's denote the side length of the square as (s) and the side length of the equilateral triangle as (t). According to the given information:

Side length of the square: \(\(s = 4x - 3\)\)

Side length of the equilateral triangle: \(\(t = 5x - 3\)\)

The perimeter of a square is given by the formula \(\(P_{\text{square}} = 4s\)\), and the perimeter of an equilateral triangle is given by the formula\(\(P_{\text{triangle}} = 3t\).\)

Given that the two figures have the same perimeter, we can set up the equation:\(\[P_{\text{square}} = P_{\text{triangle}}\]\)

\(\[4s = 3t\]\)

Substitute the expressions for (s) and (t): \(\[4(4x - 3) = 3(5x - 3)\]\)

Now, solve for (x): \(\[16x - 12 = 15x - 9\]\)

\(\[x = 3\]\)

Now that we have found the value of \(x\), we can find the side lengths of the square and the equilateral triangle: \(\[s = 4x - 3 = 4(3) - 3 = 12 - 3 = 9\]\)

\(\[t = 5x - 3 = 5(3) - 3 = 15 - 3 = 12\]\)

The area of a square is given by \(\(A_{\text{square}} = s^2\)\), so the area of the square is: \(\[A_{\text{square}} = 9^2 = 81\]\).Therefore, the correct answer is option A: 81 square units.

Answer: See explanation

Step-by-step explanation:

Correlation is a term which simply measures the strength of the linear relationship that exist between two variables that are quantitative.

In the scenario in the question, since the correlation coefficient between the variables is +0.64, it means that there is a positive correlation between the two variables which means there's a positive relationship between the repeated visits to the coffee shop and the customer's age but they're weakly positively correlated .

The chart does not represent a linear quantity

From the chart, we have the following coordinates

(x, y) = (0.10, 0.14), (0.50, 0.32), (1.00, 0.46), (1.70, 0.59) and (2.00, 0.63)

To determine if the chart is a linear quantity, we simply calculate the slope using the coordinates.

The slope is calculated as:

m = (y2 - y1)/(x2 - x1)

So, we have:

m = (0.32 - 0.14)/(0.50 - 0.10) = 0.45

m = (0.46 - 0.32)/(1.00 - 0.50) = 0.28

In the above computations, the calculated slopes are not equal

Step-by-step explanation:

Here

Sample size= n= 15

Population mean= mu = μ= $102,342

Population standard deviation = sigma = σ =$21,756

The population mean is given by mu = μ

Both the means , the sample mean and the population mean give the same measure but there is difference in their calculations and usage.

The population mean mu is calculated by using the population size N but the sample mean x bar is calculated using sample size.

In the given question the sample size is given of the students whereas the mean salaries for attorneys in New York City  gives the population mean because the attorneys in New York City contains all the attorneys given in the city. It is not a sample.

The population gives all the members of the group. So here none is missing.

The cost of one small box of fruit and the cost of one large box of fruit is $11.5 and $14.5 respectively.

Let

cost of one small box of fruit = x

cost of one large box of fruit = y

15x + 15y = 390

20x + 25y = 592.50

From (1)

x + y = 26

x = 26 - y

Substitute x = 26 - y into (2)

20x + 25y = 592.50

20(26 - y) + 25y = 592.50

520 - 20y + 25y = 592.50

- 20y + 25y = 592.50 - 520

5y = 72.50

divide both sides by 5

y = 72.50/5

y = 14.5

Substitute y = 14.5 into

15x + 15y = 390

15x + 15(14.5) = 390

15x + 217.5 = 390

15x = 390 - 217.5

15x = 172.5
