Answer:

C = 7 + 1.25t

Step-by-step explanation:

7 remains constant

1.25 changes according to t

Answer:

C(t ) = 1.25t + 7

Step-by-step explanation:

We can establish the following equation:

C(t ) = 1.25t + 7

Where:

C(t ) = represents the total cost relative to the t  number of tickets used

t = number of tickets used to play games

1.25 = cost per ticket to play games

Answer:

30% gain

Step-by-step explanation:

$30 for 10 = $3 each

$46.80 for 12 = $3.9 each

percentage change = (final price- initial price)/inital price  *100

3.9-3 = 0.9

0.9/3 = 0.3

0.3 x 100 = 30

so gain of 30%

By applying the K-means algorithm with two centers (15 and 40) to the given data set {10, 11, 14, 17, 19, 22, 23, 25, 46, 47, 59, 61}, we can create two clusters based on the similarity of data points.

The K-means algorithm is an iterative algorithm that aims to partition a given data set into K clusters, where K is a predetermined number of clusters. In this case, we have 2 centers: 15 and 40. The algorithm starts by randomly assigning each data point to one of the centers. Then, it iteratively recalculates the center of each cluster and reassigns data points based on their proximity to the updated centers. Applying the K-means algorithm with the given centers, the algorithm would assign the data points to the clusters based on their proximity to the centers. The data points closer to the center 15 would form one cluster, and the data points closer to the center 40 would form another cluster. The final result would be two clusters that group the data points in a way that minimizes the distance between the data points within each cluster and maximizes the distance between the clusters. The specific assignments of data points to clusters would depend on the algorithm's iterations and the initial random assignments, but the end result would be two distinct clusters based on the chosen centers.

The margin of error will be larger for a 99% confidence interval than for a 95% confidence interval, assuming the same sample size and level of variability in the data.

The margin of error is the range of values above and below the point estimate within which the true population parameter is likely to fall.

A higher level of confidence requires a larger margin of error. This is because as the level of confidence increases, the range of values that contains the true population parameter becomes wider.

For example, a 95% confidence interval has a margin of error of plus or minus two standard errors of the point estimate.

Increasing the confidence level to 99% would require a wider range of values, and therefore a larger margin of error, such as plus or minus three standard errors of the point estimate.

Answer:

Step 2 you should subtract 5 (aka D)

Step-by-step explanation:

Simple, its 2+ step equations.

Step 1 Look at the problem

Step 2 Subtract the second normal number by the rest (5- -12 and 19)

Step 3 answer

The Cartesian coordinates of vector A at time t are x(t) = 0, y(t) = 0, and z(t) = 5t.

To find the first derivative of the vector A, we need to differentiate each component of the vector with respect to time.

The spherical coordinates of vector A are given as:

A = 5t * u_r(ϕ(t), θ(t))

where ϕ(t) = 2t and θ(t) = 2π.

a) First, let's differentiate the radial component with respect to time:

dr/dt = d(5t)/dt = 5

Next, we differentiate the azimuthal component ϕ(t) with respect to time:

dϕ/dt = d(2t)/dt = 2

Finally, the derivative of the polar angle θ(t) with respect to time is zero, as it is a constant:

dθ/dt = d(2π)/dt = 0

Therefore, the first derivative of vector A, dA/dt, is:

dA/dt = (dr/dt)u_r + r(dϕ/dt)u_ϕ + r sin(θ)(dθ/dt)u_θ

     = 5u_r + 2tu_ϕ

b) To obtain the Cartesian coordinates x(t), y(t), and z(t) of vector A at time t, we need to convert the spherical coordinates to Cartesian coordinates. The conversion formulas are:

x = r sin(θ) cos(ϕ)

y = r sin(θ) sin(ϕ)

z = r cos(θ)

Using the given spherical coordinates:

r = 5t

θ = 2π

ϕ = 2t

Substituting these values into the conversion formulas, we get:

x(t) = (5t) sin(2π) cos(2t)

    = 0 (sin(2π) = 0)

y(t) = (5t) sin(2π) sin(2t)

    = 0 (sin(2π) = 0)

z(t) = (5t) cos(2π)

    = 5t

Therefore, the Cartesian coordinates of vector A at time t are x(t) = 0, y(t) = 0, and z(t) = 5t.

Answer: The answer is 3

Step-by-step explanation:

The constant of proportionality of the relationship shown in the graph is 3 and this can be determined by using the two-point slope form of the line.

Given :

The graph of a straight line is given.

The following steps can be used in order to determine the constant of proportionality of the relationship shown in the graph:

Step 1 - The two-point slope form of the line can be used in order to determine the constant of proportionality of the relationship shown in the graph.

Step 2 - The two-point slope form of the line is given below:

y - y1 / x - x1 = y2 - y1 / x2 - x1

where (x1, y1)  and (x2, y2)  points on the line.

Step 3 - So, substitute (1,3) and (2,6) in the above equation.

y - 3 / x - 1 = 6 - 3 / 2 - 1

Step 4 - Simplify the above equation.

(y - 3) = 3(x - 1)

y - 3 = 3x - 3

y = 3x

So, the constant of proportionality of the relationship shown in the graph is 3. Therefore, the correct option is B).

The percentage of total deliveries made by Aldo is 60%.

A percentage is a number or ratio expressed as a fractin of 100. It is often denoted using a percent "%" sign.

It is given that,

Total number of deliveries to be made = 30

Deliveries made so far = 18

Now, for the percentage of his total deliveries we need to divide deliveries made so far with the total deliveries,multiplied by 100%.

⇒ Percentage of his total deliveries = Deliveries made so far/Total number of deliveries

⇒ Percentage of his total deliveries = 18/30*100%

⇒ Percentage of his total deliveries = 60%

Hence,the percentage of total deliveries made by Aldo is 60%.

Answer:

Step-by-step explanation:  

Move all terms that don't contain x to the right side and solve.

At x=(-27+√759)/40, f(x) is minimum

At x=(-27-√759)/40, f(x) is maximum , for the given function f(x)=8x⁵+27x⁴-2x³-0x₂+0+6

A relative maximum point occurs when the function's direction switches from increasing to decreasing (making that point a "peak" in the graph). A relative minimum point, on the other hand, is a point at which the function switches from decreasing to growing (making that point a "bottom" in the graph).

If f'(k) = 0, and f"(k) = 0, then x = k is a point of relative maxima. The point at x= k is known as the relative maxima, and f(k) is known as the maximum value of f. If f'(k) = 0, and f"(k) >0, then x = k is a point of relative minima. The point at x = k is known as the relative minima, and f(k) is known as the minimum value of f.

Given,

f(x)=8x⁵+27x⁴-2x³-0x₂+0+6

f(x)=8x⁵+27x⁴-2x³+6

f'(x)=40x⁴+108x³-6x²=0

20x²+54x-3=0

x= (-54±√54²-2(20)(-3))/4(20)

x=(-54±√3036)/4(20)

x= (-54± 2√759)/4(20)

x= (-27±√759)/40

f"(x)=40x+54

f"((-27±√759)/40)=40((-27±√759)/40)+54

= -27+√759+54

=  27+√754≥0

∴ At x=(-27+√759)/40, f(x) is minimum.

At x=(-27-√759)/40

f"(x)=40x+54

=40((-27-√759)/40)+54

=-27-√754+54

=27-√754≤0

∴ At x=(-27-√759)/40, f(x) is maximum.

Answer: if its a proper fraction, 1 is always greater. Just know that because something doesnt look right here!

Step-by-step explanation:

since r is so widely used, it is appropriate to calculate r for nonlinear data: False.

The calculation of r (Pearson's correlation coefficient) is based on the assumption that the relationship between the two variables is linear. Therefore, it is not appropriate to calculate r for nonlinear data as it may give misleading results.

In summary, it is not appropriate to calculate r for nonlinear data as it assumes a linear relationship between the variables. Other methods such as Spearman's rank correlation or Kendall's tau may be used for nonlinear data.


n: The correlation coefficient 'r' is specifically designed to measure the strength and direction of a linear relationship between two variables. While it is widely used, calculating 'r' for nonlinear data is not appropriate, as it will not accurately capture the true nature of the relationship between the variables.

When dealing with nonlinear data, it is better to use other statistical methods designed for such data, rather than relying on the correlation coefficient 'r'.
