A statistic is, 4.13%.

Given that;

On Feb. 19th, 2010, 4.13% of the randomly selected spots had potamogeton (a type of seagrass)

Since, A parameter is a value that is determined from all of the data, whereas a statistic is a value that is produced from a sample of the data.

Here, The percentage of spots containing portamento in this instance was solely determined from a randomly chosen sample, making it a statistic.

Hence, It would be a parameter if the percentage was determined using the whole population of spots.

Thus, 4.13% is a statistic.

Answer:

In my view 1st answer is correct..

Answer:

x = 1, x = 19

Step-by-step explanation:

Given

2x² - 20x = x² - 19 ( subtract x² - 19 from both sides )

x² - 20x + 19 = 0 ← in standard form

(x - 1)(x - 19) = 0 ← in factored form

Equate each factor to zero and solve for x

x - 1 = 0 ⇒ x = 1

x - 19 = 0 ⇒ x = 19

the total amount is "x", which oddly enough is 100%.

we also know that 28,200 is the 19.9%, so

\(\begin{array}{ccll} amount&\%\\ \cline{1-2} x & 100\\ 28200& 19.9 \end{array} \implies \cfrac{x}{28200}~~=~~\cfrac{100}{19.9} \\\\\\ 19.9x=2820000\implies x=\cfrac{2820000}{19.9}\implies x\approx 141708\)

Step-by-step explanation:

∠ L = 180° - (60 + 60)° = 180° - 120° = 60° [ sum of angles in Δ = 180° ]

Since the 3 angles are 60° , then the triangle is equilateral with the 3 sides being congruent.

Then

5x - 3 = 4 ( add 3 to both sides )

5x = 7 ( divide both sides by 5 )

x = \(\frac{7}{5}\) = 1.4

and

2y + 6 = 4 ( subtract 6 from both sides )

2y = - 2 ( divide both sides by 2 )

y = - 1

The minimum fraction of data contained within 2.56 standard deviations is about 99.7%, meaning that 99.7% of the data will be contained within 2.56 standard deviations.

The minimum fraction of the data that fall within 2.56 standard deviations is approximately 99.7%. This means that 99.7% of the data will be contained within 2.56 standard deviations, where a standard deviation refers to the typical variation in data distribution. This is because the data typically follow a Gaussian distribution, which means that 68.2% of the data will be included within an expected deviation, 95.4% will be contained within two expected deviations, and 99.7% will be contained within three expected deviations. This relationship makes it possible to determine the minimum fraction of the data included within the standard deviation of 2.56.

If construction of many average quality homes began in an area that is known for having many high quality homes, it is likely that the overall property values of the homes in the neighborhood would decrease.

Explanation:

The presence of many high quality homes in a neighborhood tends to contribute to higher property values. These high quality homes often set a standard and attract buyers who are willing to pay a premium for the desirable location and quality of housing.

However, when a large number of average quality homes are constructed in the same area, it can lead to a dilution of the overall quality and desirability of the neighborhood. The increased supply of average quality homes may result in increased competition among sellers and a decreased demand from buyers who are seeking higher quality homes. As a result, property values in the neighborhood are likely to decrease.

Additionally, the introduction of average quality homes may also change the perception and reputation of the neighborhood. Buyers who were initially attracted to the area for its high quality homes may be less inclined to purchase in a neighborhood with a mixture of average and high quality homes, further impacting property values.

To find the length of the image \(\overline{G'H'}\), multiply the length of the preimage \(\overline{GH}\) by the scale factor of \(4\).

The matrix K is \(\left[\begin{array}{cccc}1&0&0&0\\0&1&0&0\\0&0&j&-j\\0&0&0&0\end{array}\right]\) .

The eigenvalues of A are the roots of the characteristic polynomial of A, which is:

det(A - xI) = (x + 1)(x + 3)(x + 4)(x + 10)

The eigenvalues of A are -1, -3, -4, and -10.

We want the eigenvalues of A - BK to be -1, -1, -1 + j, and -1 - j. The characteristic polynomial of A - BK is:

det(A - BK - xI) = (x + 1)(x + 1)(x + 1 + j)(x + 1 - j)

To make the eigenvalues of A - BK to be -1, -1, -1 + j, and -1 - j, we need to set the following equations equal to 0:

(x + 1)(x + 1) = 0

(x + 1 + j)(x + 1 - j) = 0

The first equation gives x = -1 and x = -1. The second equation gives x = -1 + j and x = -1 - j.

Therefore, the matrix K must be such that B * K = [-1, -1, -1 + j, -1 - j]T.

One possible matrix K is:

\(\left[\begin{array}{cccc}1&0&0&0\\0&1&0&0\\0&0&j&-j\\0&0&0&0\end{array}\right]\)

This matrix satisfies the equation B * K = [-1, -1, -1 + j, -1 - j]T, so it is a possible value of K.

Another possible matrix K is:

\(\left[\begin{array}{cccc}0&0&j&-j\\1&0&0&0\\0&1&0&0\\0&0&0&0\end{array}\right]\)

This matrix also satisfies the equation B * K = [-1, -1, -1 + j, -1 - j]T, so it is also a possible value of K.

To calculate the principal repaid by the 17th monthly payment of $750 on a $22,000 loan at 15% compounded monthly, we need to calculate the monthly interest rate, the remaining balance after 16 payments, and the interest portion of the 17th payment.

The monthly interest rate is calculated by dividing the annual interest rate by the number of compounding periods per year. In this case, it would be 15% / 12 = 1.25%.

The remaining balance after 16 payments can be calculated using the loan balance formula:

\($$B = P(1 + r)^n - (PMT/r)[(1 + r)^n - 1]$$\)

Where B is the remaining balance, P is the initial principal, r is the monthly interest rate, n is the number of payments made, and PMT is the monthly payment amount.

Substituting the values into the formula, we get:

\($$B = 22000(1 + 0.0125)^{16} - (750/0.0125)[(1 + 0.0125)^{16} - 1]$$\)

After calculating this expression, we find that the remaining balance after 16 payments is approximately $17,135.73.

The interest portion of the 17th payment can be calculated by multiplying the remaining balance by the monthly interest rate: $17,135.73 * 0.0125 = $214.20.

Therefore, the principal repaid by the 17th payment is $750 - $214.20 = $535.80.

The total number of possible vacation packages 288.

The fundamental concept of repeatedly adding the same number is represented by the process of multiplication.

The number of ways to choose a hotel or a cabin is 7 + 5 = 12, and the number of ways to choose one of each of the remaining options is 4 x 3 x 2 = 24, since there are 4 meal plans, 3 escape rooms, and 2 amusement parks to choose from.

To find the total number of possible vacation packages, we can multiply these numbers:

Total number of possible vacation packages = 12 x 24

Total number of possible vacation packages = 288

Therefore, there are 288 possible vacation packages.

Answer:

It is always positive because the discriminant is negative and therefore has no roots. This can also be interperted as the equation will always be above the x-axis on the parabola and therefore always be positive.

Step-by-step explanation:

The value of the quadratic expression (x - 4)² + 4 will be always positive.

Let the point (h, k) be the vertex of the parabola and a be the leading coefficient. Then the equation of the parabola will be given as,

y = a(x - h)² + k

The quadratic expression is given below.

⇒ x² - 8x + 20

Convert the expression into a vertex form, then we have

⇒ x² - 8x + 16 + 4

Answer:

\(Height = 30cm\)

\(Length = 360cm\)

Step-by-step explanation:

Given

Scale Measurement

\(Height = 2cm\)

\(Length = 24cm\)

Required

Determine the possible actual measurement

First, calculate the equivalent ratio.

\(Ratio = \frac{Length}{Height}\)

\(Ratio = \frac{24cm}{2cm}\)

\(Ratio = 12\)

To do this, we pick a scale factor.

Assume the scale factor is 15.

The actual measurement will be:

\(Height = 2cm * 15\)

\(Height = 30cm\)

\(Length = 24cm * 15\)

\(Length = 360cm\)

When the scale ratio is calculated, we have:

\(Ratio = \frac{Length}{Height}\)

\(Ratio = \frac{360cm}{30cm}\)

\(Ratio = 12\)

Note that both have the same equivalent ratios of 12.

So, whatever the scale ratio you use, the equivalent ratio will be the same
