Hey there. I'm Avery, and I'm here to help you with your amazing question! <33
I believe the answer is: $16.95 per fern tree.

+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

[~Answer Explanation~]:

first, you want to find how much money the 7 balloons cost:

7(2.30) = 16.10

second, you want to find how much money you have left AFTER buying 7 balloons:

50 - 16.10 = 33.90

third, divide the money you have left by 2 (2 fern trees) to find the final answer:

33.90/2 = 16.95

Answer:

144 square foot

Step-by-step explanation:

Area of rectangle: Length × breadth

Area of rectangle = 16 × 9

                             = 144 square foot

Step-by-step explanation:

since there is no graph it's a bit hard to answer this question, but I'll try. I can help solve the equation that represents the ratio of the two numbers:

(x + 1/2)/y = 1/3

This can be simplified to:

x + 1/2 = y/3

To graph this equation, you would need to plot points that satisfy the equation. One way to do this is to choose a value for y and solve for x. For example, if y = 6, then:

x + 1/2 = 6/3

x + 1/2 = 2

x = 2 - 1/2

x = 3/2

So one point on the graph would be (3/2, 6). You can choose different values for y and solve for x to get more points to plot on the graph. Once you have several points, you can connect them with a line to show the relationship between x and y.

(Like I said, it was a bit hard to answer this question, so I'm not 100℅ sure this is the correct answer, but if it is then I hoped it helped.)

The equation can be used to find other combinations of x and y is  y^2 = (1/16)x^3

The direct variation from the square of y to the cube of x is represented as:

y^2 = kx^3

Where k represents the variation constant.

When x = 4, y = 2.

So, we have:

2^2 = k * 4^3

This gives

4 = 64k

Divide both sides by 64

k = 1/16

Substitute k = 1/16 in y^2 = kx^3

y^2 = (1/16)x^3

Hence, the equation can be used to find other combinations of x and y is  y^2 = (1/16)x^3

Study sample size is an important factor in determining the credibility of research because a larger sample size increases the power of the study and reduces the likelihood of random error.

Article publication date is also important because research on a topic can become outdated over time and newer studies may have different or more robust findings.

The probability that a test taker chosen at random takes 9 minutes or more to read the article is 0.38. Rounded to four decimal places, this is 0.3800.

To find the probability that a test taker chosen at random takes 9 minutes or more to read the article, we need to calculate the integral of the probability density function f(t) from 9 to 10 (since t is between 0 and 10).
∫(9 to 10) 0.012t^2 − 0.0012t^3 dt
Using the power rule of integration, we get:
[0.004t^3 - 0.0003t^4] from 9 to 10
Substituting the limits, we get:
[0.004(10)^3 - 0.0003(10)^4] - [0.004(9)^3 - 0.0003(9)^4]

Answer: -4.2c + 4.8d

Step-by-step explanation:

Multiply each number by 0.6 to get -4.2c + 4.8d.

The equation h(t) = -16t² + 24t is an illustration of a quadratic model

The equation that represents the path of the kick ball is given as

h(t) = -16t² + 24t

The fielder catches the ball at a height of 3 ft above the ground.

This means that:

h(t) = 3

So, we have:

-16t² + 24t = 3

Hence, the equation when the fielder catches the ball is -16t² + 24t = 3

In (a), we have:

-16t² + 24t = 3

Rewrite as:

-16t² + 24t - 3 = 0

Next, we determine the solutions of -16t² + 24t - 3 = 0 using a graphing technology

From the graph (see attachment), we have the following solutions

t = 0.14 and t = 1.36

Hence, the fielder will catch the ball after 0.14 seconds or 1.36 seconds

The area to the right of 2.6 in a t-distribution with n degrees of freedom is 0.9082, assuming the sample is a random sample from a distribution that is reasonably normally distributed and that we are doing inference for a population mean.

We can use a t-distribution table or a statistical software program to find the area to the right of 2.6. Here, I'll show you how to use a t-distribution table:

Determine the degrees of freedom (df) for the t-distribution. This is equal to n - 1.

Look up the t-value that corresponds to a one-tailed probability of 0.05 and df.

Multiply the t-value by -1 to get the positive value for the right tail. In other words, we need the value for the right tail, so we flip the sign of the t-value.

Add 0.5 to the result to account for the area to the left of 2.6. This gives us the cumulative probability from negative infinity to 2.6.

Subtract the result from 1 to get the area to the right of 2.6.

For example, suppose we have a sample of size n = 10. Then, the degrees of freedom for the t-distribution would be df = 10 - 1 = 9. Using a t-distribution table, we can look up the t-value that corresponds to a one-tailed probability of 0.05 and df = 9:

t-value = 1.833

Since we need the positive value for the right tail, we multiply by -1 to get:

t-value = -1.833

Adding 0.5 to account for the left tail gives:

t-value + 0.5 = -1.333

Finally, subtracting this result from 1 gives us the area to the right of 2.6:

Area to the right of 2.6 = 1 - 0.0918 = 0.9082

4. (0, -8) and (3, 2): √109 (exact value)

3. (-1, 4) and (1, -1): √29 (exact value)

We may use the distance formula to calculate the separation between each pair of points:

d = √((x₂ - x₁)² + (y₂ - y₁)²),

where the two points' coordinates are represented by (x1, y1) and (x2, y2), respectively.

Let's determine the separation between each pair of points:

1. (1, -4.6) and (3, -7):

d = √((3 - 1)² + (-7 - (-4.6))²)

= √(2² + (-2.4)²)

= √(4 + 5.76)

= √9.76

= 3.12 (rounded to two decimal places)

2. (-6, -5) and (2, 0):

d = √((2 - (-6))² + (0 - (-5))²)

= √(8² + 5²)

= √(64 + 25)

= √89 (exact value)

M = (-12, -1) and M = (4, 0):

d = √((4 - (-12))² + (0 - (-1))²)

= √(16² + 1²)

= √(256 + 1)

= √257 (exact value)

4. (0, -8) and (3, 2):

d = √((3 - 0)² + (2 - (-8))²)

= √(3² + 10²)

= √(9 + 100)

= √109 (exact value)

3. (-1, 4) and (1, -1):

d = √((1 - (-1))² + (-1 - 4)²)

(a) The eigenvalues of A are 7 and 3, (b) The corresponding unit eigenvectors of A are [1, 1] and [-1, 1]. (c) The relationship between the eigenvalues of A and the trace of A is that the sum of the eigenvalues is equal to the trace of A.

In this case, the sum of the eigenvalues is 7 + 3 = 10, which is equal to the trace of A. The relationship between the eigenvalues of A and the determinant of A is that the product of the eigenvalues is equal to the determinant of A.

In this case, the product of the eigenvalues is 7 * 3 = 21, which is equal to the determinant of A.

Here is a more detailed explanation of how to solve for the eigenvalues and eigenvectors of A:

To find the eigenvalues of A, we can use the following formula:

λ = det(A - λI)

where λ is the eigenvalue and I is the identity matrix. In this case, we have:

λ = det(A - λI) = det([2 3] - λ[1 0]) = det([2 - λ 3])

Expanding the determinant, we get:

λ = λ^2 - 5λ + 6

Solving for λ, we get:

λ = 7 or λ = 3

To find the corresponding unit eigenvectors of A, we can use the following formula:

v = (A - λI)^(-1)b

If derivative of \(f(x)=ln(x+4+e^{(-3x)})\), then f '(0) = -2/5.

What is derivative?

In calculus, the derivative of a function is a measure of how the function changes as its input changes. More specifically, the derivative of a function at a certain point is the instantaneous rate of change of the function at that point.

To find f'(0), we first need to find the derivative of f(x) with respect to x. Using the chain rule, we get:

\(f'(x) = 1 / (x+4+e^{(-3x)}) * (1 - 3e^{(-3x)})\)

Now we can find f'(0) by substituting the value x=0:

\(f'(0) = 1 / (0+4+e^{(-3(0))}) * (1 - 3e^{(-3(0))})\)

f'(0) = 1 / (4+1) * (1 - 3)

f'(0) = -2/5

Therefore, f'(0) = -2/5.

To find the median number of musical instruments played, we first need to arrange the data in ascending order:

0, 0, 0, 0, 1, 1, 2, 2, 3, 3, 3

Next, we count the total number of responses, which is 15. Since 15 is an odd number, the median will be the average of the middle value.

The middle value is 1

Hence, the median number of musical instruments played is 1.
