The number of deer that should be estimated live in the region is:

50.

To estimate the deer population, the method of capture-recapture is commonly used.

This method involves counting the number of tagged animals (in this case 220) and then counting the number of tagged animals in a subsequent sample (in this case 8 samples of 50 deer each).

By comparing the number of tagged deer in the sample to the total number of tagged deer, we can estimate the total population.

Let N be the total population of deer. The estimated population size can be calculated using the formula:

In this case, the number of tagged deer in the sample is 220. So, the estimated population size is:

Therefore, it is estimated that there are 50 deer living in the region.

Yes, you can find the standard error now by taking the standard deviation divided by the square root of the sample size.

The standard deviation in a data set is the mean deviation of the data from their mean.

For sample size n for a data set with data points X1, X2, X3……..Xn for exact standard deviation:

1. Calculates the arithmetic mean M of the set data by adding them all and dividing by n.

M = ( X1+X2+ X3+…..+Xn) / n

2. Calculate the deviation (D) for each data point from the mean M

D = (Xi-M) for all

3. Squaring and sum of all deviations, sum of squares (SS)

4. Divide SS by n.This quantity is the sample variance V

5. Take the square root of V.

6. This quantity is the sample standard deviation, SD.

There are some specific terms and issues to consider. If you are estimating the standard deviation of a population from a sample and the population mean $ is not known, M serves as an unbiased estimate of $. Again, SS is divided by (n-1), not n.

The resulting standard deviation is an unbiased estimate of the population standard deviation based on the sample size, n. If the population mean is known, use that mean instead of the sample mean. , and the SD of the sample is only calculated for n through SS dives.

The area of shape B which is of 15 cm, is 312.5 cm²

Let us assume that the area of the shape B is x square units.

The dimensions of shape A is 12 cm

The area of the shape A is 200 cm²

The dimensions of shape B is 15 cm

The area of the shape B is x cm²

Since A and B are two similar 2D shapes their dimensions must be in proportion.

So, we get an equation,

A² / B² = 200 / x

12² / 15² = 200 / x

144 / 225 = 200 / x

x = 312.5 cm²

Answer:

#7:  x = 7

#8:  AC = 52

Step-by-step explanation:

We know that part + part = whole.

Thus, AB + BC = AC

Using this fact, we can solve for x:

[tex]6x-3+2x-1=10x-18\\8x-4=10x-18\\8x=10x-14\\-2x=-14\\x=7[/tex]

We can simply plug in x in 10x-18 to find the length of AC:

[tex]10(7)-18=AC\\70-18=AC\\52=AC[/tex]

You can also check that AB + BC = AC by plugging in x for 6x -3 and 2x -1 and finding the sum of the two parts of the line:

[tex]6(7)-3+2(7)-1=52\\42-3+14-1=52\\39+13=52\\52=52[/tex]

The proof for the the lines p and q are parallel is given below.

Alternate exterior angles are the angles formed on the two opposite sides of the transversal which are on the outer side of the parallel lines.

Given that,

∠1 ≅ ∠2 or ∠2 ≅ ∠1.

Now ∠1 ≅ ∠3, by the vertical angles theorem.

(By the vertical angles theorem, vertical angles formed by two intersecting lines are congruent).

Then ∠2 ≅ ∠3, by the transitive property.

(Transitive property states that, if a = b and b = c, then a = c)

By the corresponding angles converse postulate, two lines p and q are parallel.

(If the corresponding angles of two lines cut by a transversal are equal, the lines are parallel).

The number of degrees of freedom in a t-test is calculated as the sample size -2.

In this case, if Deja is performing a t-test to determine if there is a mean difference between the number of abrasions per leaf produced by the two strains, she needs to have the sample size of both strains.

Assuming she has n1 and n2 samples for each of the two strains, the degrees of freedom can be calculated as:

df = n1 + n2 - 2

The degrees of freedom represent the number of independent pieces of information in the sample data that are used to estimate the population parameters. The t-test statistic is then compared to a t-distribution with the calculated degrees of freedom to determine the significance of the results.

Measurements are important for a safe and secure structure, as they must adhere to local building codes and regulations. Preliminary planning can be used to estimate the height, width, and length of the ramp and the amount of concrete and other materials needed.

A measurement is a measurable quantity that includes length, breadth, height, area, volume, weight, or time. Measurements are used to measure an object's or area's size, shape, or qualities.

A) Estimating measurements for a construction project such as this is not advisable, as accuracy is essential for ensuring the wall is stable and safe for use. Calculations must be precise in order to ensure the dimensions, material strength, and angles are correct, which is why it is important to use exact measurements in the plans.

B) In some cases, estimates may be acceptable. For example, the approximate number of blocks or pieces of material needed may be estimated based on the overall size and shape of the wall. Additionally, estimates of the time needed to complete the project may be made based on the experience of the construction team and the complexity of the project.

Step-by-step explanation:

No, there are no whole numbers with a cube root between 0 and 1. A cube root of a number is a value that, when multiplied by itself three times, gives the original number.

The cube root of a number is a value that, when multiplied by itself three times, gives the original number. The cube root of a positive number is always positive. If a positive number is between 0 and 1, then its cube will be even smaller.

For example, the cube root of 8 is 2, and the cube root of 27 is 3. If we take the cube root of a number less than 1, such as 0.5, the result is less than 1. However, since we are talking about whole numbers, 0.5 is not a whole number and therefore not in the scope of the question.

Therefore, it can be concluded that there are no whole numbers with a cube root between 0 and 1 because any positive whole number raised to the power of 1/3 will result in a value greater than 1.

To find f(2), we simply substitute 2 for x in the function f(x)=5x+12 and simplify:

Therefore, f(2) = 22.

Step-by-step explanation:

The initial amount, a, in the exponential function g(x) = 14 × 2x is 14, and the growth factor, b, is 2.

This can be determined by looking at the equation and noting that the coefficient of x is 2, which indicates that the base of the exponential is 2. We can also calculate the initial amount and growth factor mathematically.

To calculate the initial amount, a, we can take the equation g(x) = 14 × 2x and set x = 0, yielding g(0) = 14 × 20, which simplifies to 14. To calculate the growth factor, b, we can take the natural log of both sides of the equation to yield ln(g(x)) = ln(14 × 2x).

Simplifying this gives

ln(g(x)) = ln(14) + ln(2x).

We can then divide both sides by x to yield

ln(g(x))/x = ln(14) + ln(2)/x.

We can then take the limit as x approaches 0, which yields

ln(g(0))/0 = ln(14) + ln(2)/0.

This simplifies to

ln(g(0)) = ln(14) + ln(2), which can be rearranged to

ln(2) = ln(g(0)) - ln(14).

Taking the exponential of both sides gives us

2 = e^(ln(g(0)) - ln(14)), which simplifies to

2 = g(0)/14, or b = g(0)/14 = 2.

This shows that the initial amount, a, is 14, and the growth factor, b, is 2.

The ticket price that would maximize the profit is $1 and the maximum profit would be $14,450.

To maximize the profit, we need to find the maximum value of the function P(t) = -50t^2 + 100t + 14,400.

The maximum value can be found by finding the vertex of the parabolic equation. The vertex can be found using the formula:

t = -b / 2a

where a, b, and c are the coefficients of the equation in the form of y = ax^2 + bx + c. In this case, a = -50, b = 100, and c = 14,400.

Substituting the values into the formula, we get:

t = -b / 2a = 100 / (-2 * -50) = 100 / 100 = 1

So, the ticket price that would maximize the profit is $1. To find the maximum profit, we can plug in t = 1 into the function:

P(1) = -50 * 1^2 + 100 * 1 + 14,400 = -50 + 100 + 14,400 = 14,450

So the maximum profit would be $14,450.
