Answer: $18 000

Step-by-step explanation:

40 bottles per box

40*15 = 600 bottles total

600 * $30 = $18 000

She made $18 000 in total.

Amount of money she receives from sale of 15 boxes of perfume in all is $18,000.

Proportions are defined as the concept where two or more ratios are set to be equal to each other.

Given that,

Number of bottles of perfume packed in a box = 40

Cost for each perfume = $30

Cost for 40 perfumes = 40 × $30 = $1200

So cost for a box of perfume = $1200

Cost for 15 boxes of perfume = 15 × $1200

                                                 = $18,000

Hence the amount for 15 boxes of perfume is $18,000.

Step-by-step explanation:

The formula "I=PRT" is the simple interest formula, where:

I = interest

P = principle (the initial amount of money)

R = interest rate (as a decimal)

T = time (in years)

Given the values of P, R, and T:

P = 5,600

R = 0.2

T = 4

We can plug these values into the formula to find the interest:

I = P * R * T = 5,600 * 0.2 * 4 = 4,480

So, the interest earned on a principle of $5,600 at an interest rate of 0.2 (or 20%) for 4 years would be $4,480.

Answer:

C-intercept(s): (0,0)

t-intercept(s): (0,0), (6,0), (-4,0)

Step-by-step explanation:

the C-intercept is essentially the y intercept. this occurs when t=0:

C(0) = 4(0)^4 - 8(0)^3 - 96(0)^2 = 0. so the C-intercept is at (0,0).

the t-intercept is the x-intercept, and occurs when C(t) = 0:

4t^4 - 8t^3 - 96t^2 = 0 = [tex]4t^{2} (t-6)(t+4)[/tex]. C(t) = 0 when t = 0, t= 6, and t = -4.

Answer:

19

Step-by-step explanation:

top = bottom so 4x-4y = 3x+5y so x = 9y

left = right so 2-2y = x-3y so x= y+2

so 9y = y+2

8y = 2

y= 0.25

x=2.25

so just add them all up

2*(4x-4y) + 2*(2-2y )

= 8*(x-y)+4*(1-y)

=16+4*0.75

Since the rabbit from the previous problem started at 10, it would be at 17 units on the number line after the same three jumps.

In Mathematics, a number line is a type of graph with a graduated straight line which comprises both positive and negative numerical values that are placed at equal intervals along its length.

From the previous problem, the total distance covered by the rabbit is given by:

Total distance = 4 units + 2 units + 1 unit

Total distance = 7 units.

Since the second point is at 10 units and the open circle arrow points to the right of the number line, the rabbit would cover 7 more distance from this point:

Total distance = 10 units + 7 units

Total distance = 17 units.

Random sampling error is the error due to the particular sample selected being an imperfect representation of the population of interest.

When an analyst selects a sample that is not a true representation of the entire population of data, they commit a statistical error known as a sampling error. The results of the sample therefore do not fairly represent the results of the entire population.

Sampling is a type of analysis where a small sample of observations are selected from a larger population. The selection process has the potential to result in both sampling errors and non-sampling errors.

According to the definition, random sampling error is the error that results from the particular sample being chosen not accurately representing the population of interest. It could be described as the difference between the true mean value for the sample and the true mean value of the population.

1a. The null hypothesis in this setting would mean that the proportion of students who completed their math homework is equal to or greater than 75%.

1b. The p-value represents the probability of observing a sample proportion as extreme as or more extreme than the sample proportion observed (68%), given that the null hypothesis is true. In this case, the p-value of 0.1265 indicates that there is a 12.65% chance of observing a sample proportion as extreme or more extreme than 68%, assuming the true proportion is equal to or greater than 75%.

1c. At the alpha = 0.05 significance level, we reject the null hypothesis if the p-value is less than 0.05. In this case, the p-value of 0.1265 is greater than 0.05, meaning we fail to reject the null hypothesis. Therefore, at the alpha = 0.05 significance level, we cannot conclude that less than 75% of students completed their math homework.

Answer: To calculate the decrease in value of Samir's digger after 10000 hours, we need to determine its value at the end of each year, taking into account the yearly depreciation of 18%.

Here's the calculation for the first year:

Value at the end of Year 1 = £35950 - (£35950 * 18%) = £29576

And for the second year:

Value at the end of Year 2 = £29576 - (£29576 * 18%) = £24480.48

And so on, until we reach 10000 hours. To determine the exact value after 10000 hours, we would need to perform the calculation for each year until we reach the total number of hours used. However, this calculation would involve multiple steps and can become quite complex. A simpler way to estimate the decrease in value would be to use the concept of present value.

The account has an annual interest rate of 6.80%, compounded continuously.

Interest is the cost associated with the boring money or to return on for lending money it is typically expressed as a percent of the principal amount borrowed or lent and usually the paid periodically over the life of loan interest can also be on from investment such as saving account bonds and the other financial instrument.

The interest rate of the account can be calculated as follows:

Rate = ln(1,698.49/1,051)/(8×ln(1))

Rate = 0.0680 or 6.80%

This means that the account has an annual interest rate of 6.80%, compounded continuously.

The actual food is 115% of the budgeted food.

The percentage is defined as a ratio expressed as a fraction of 100.

The data is given in the question, as follows:

Budgeted: 200

Actual: 230

To determine the percentage of the budgeted food that is the actual food, we can divide the actual amount by the budgeted amount and multiply by 100.

Percentage = (Actual / Budgeted) * 100

Percentage = (230 / 200) x 100

Percentage = 1.15 x 100

Apply the multiplication operation, and we get

Percentage = 115%

So, the actual food is 115% of the budgeted food.

In a sequence diagram, the vertical line labeled 'a' is used to represent the amount of time during which an object is active and capable of interacting with the other objects in the use case. This time frame is usually shown as a timeline to give the viewer an idea of how long the object is active. The time ‘a’ could include any kind of interaction between the objects, such as sending messages, waiting for a response, or any other type of interaction. The ‘a’ time frame also indicates when an object is no longer interacting with the other objects in the use case. This timeline can be used to identify points where a user or system may need to wait for a response or where a user or system is no longer able to interact with the other objects in the use case. In essence, the ‘a’ timeline helps to demonstrate how long the use case is active, how long an object is interacting with other objects in the use case, and when the use case has ended.

The required equation of the quadratic function in standard form is:  
f(x) = (1/4) x² + 6.

A parabola is a cross-section cut out of the cone and represented by an equation f(x) = a(x - h)² + k.

The standard form of a quadratic function is given by:

f(x) = a(x - h)² + k

where (h, k) is the vertex of the parabola.

Given the vertex (0, 6) and the point (2, 7), we can find the values of a and k and use them to write the equation in standard form.

Let's use the vertex form of the equation:

f(x) = a(x - h)² + k

Since the vertex is (0, 6), we have h = 0 and k = 6:

f(x) = a(x - 0)² + 6

f(x) = a × x² + 6

Next, we use the point (2, 7) to find the value of a:

f(2) = a × 2² + 6

7 = 4a + 6

7 - 6 = 4a

1 = 4a

a = 1/4

So, the equation of the quadratic function in standard form is:  
f(x) = (1/4) x² + 6
