When a predator is referred to as a keystone species, it means that its presence and influence in an ecosystem are crucial for maintaining the balance, stability, and biodiversity of the entire system.

When a predator is considered a keystone species, it means that it plays a crucial role in maintaining the balance and stability of its ecosystem. The presence or absence of this predator has a significant impact on the structure and functioning of the entire ecosystem.

A keystone species exerts a disproportionate influence on the ecosystem compared to its abundance or biomass. Removing or reducing the population of a keystone predator can lead to cascading effects throughout the food web, causing changes in species composition, population dynamics, and overall ecosystem health.

Predators as keystone species often help regulate the populations of their prey species, preventing any one species from dominating the ecosystem. By controlling the abundance and behavior of their prey, they can indirectly impact the distribution and diversity of other organisms, leading to a more balanced and diverse ecosystem.

The approximate ground area covered by the triangular building is K ≈ 11,869.39 square feet.

To approximate the ground area covered by the triangular building, we can use Heron's formula. Heron's formula allows us to calculate the area of a triangle when we know the lengths of its sides.

Given the lengths of the three sides of the triangular building as follows:

a = 82 feet

b = 195 feet

c = 177 feet

We can calculate the semi-perimeter (s) of the triangle using the formula:

s = (a + b + c)/2

Substituting the given values:

s = (82 + 195 + 177)/2

s = 454

Now, we can use Heron's formula to calculate the area (K) of the triangle:

K = √(s(s-a)(s-b)(s-c))

Substituting the values:

K = √(454(454-82)(454-195)(454-177))

K ≈ √(454(372)(259)(277))

K ≈ √(140,870,376)

Approximating the square root value:

K ≈ 11,869.39

Therefore, the approximate ground area covered by the triangular building is K ≈ 11,869.39 square feet.

Answer:

x + y = 9

y = x + 2

Step-by-step explanation:

We need to write a system of equations to represent the given situation . The statements are ,

Statement 1:- The sum of x and y is 9.

Mathematically , we can write it as ,

\(\rm\implies x + y = 9 \)

Statement 2:- The value of y is two more than the value of x.

This simply means that y equals to 2 + x , that is

\(\rm\implies y = x+2\)

Therefore the system of equations will be ,

Also when we will try to solve the equations we will get ,

\(\rm\implies x + y = 9 \)

Put y = x + 2 , we have ,

\(\rm\implies x + x + 2= 9 \)

Add the like terms ,

\(\rm\implies 2x +2 = 9 \)

Transpose 2 to RHS ,

\(\rm\implies 2x = 9 -2 = 7\)

Divide both sides by 2 ,

\(\rm\implies \boxed{\blue{\rm\quad x = 3.5\quad}}\)

Similarly we will get the value of as ,

\(\rm\implies 3.5 + y = 9 \)

Transpose 3.5 to RHS ,

\(\rm\implies y = 9 - 3.5 \)

\(\rm\implies \boxed{\blue{\rm\quad y = 5.5\quad}}\)

Therefore ,

\(\begin{cases} \rm x = 3.5 \\\\\rm y = 5.5 \end{cases}\)

f(x) = (x + 2/3)q(x) + r, where q(x) is the quotient and r is the remainder. By using a graphing utility and evaluating f(k) and r with k = -2/3, we can verify that f(k) = r.

Given f(x) = \(15x^4 + 10x^3 -15x^2 + 11\) and k = -2/3, we need to express the function in the form f(x) = (x − k)q(x) + r.

To find the quotient q(x) and remainder r(x), we can use polynomial division or synthetic division. By dividing f(x) by (x - k), we can obtain q(x) and r(x).

Using a graphing utility to evaluate f(k) and r, we can substitute the value of k = -2/3 into the function and calculate f(k) and r. If f(k) = r, then the function can be written in the desired form.

By performing the polynomial division or synthetic division and evaluating f(k) and r, we can demonstrate that f(k) = r, confirming that the function can be expressed as f(x) = (x − k)q(x) + r.

Step-by-step explanation:

The test statistic for this sample is z = (0.254 - 0.203) / (p_hat * (1 - p_hat) * (1/n1 + 1/n2))

Based on the given information, we can set up the hypotheses as follows:

Null hypothesis: p1 - p2 = 0
Alternative hypothesis: p1 - p2 > 0

where p1 represents the proportion of successes in the first population and p2 represents the proportion of successes in the second population.

Since the sample sizes are large (n1 and n2 are not given, but we can assume they are large enough for the normal approximation to hold), we can use the normal distribution to approximate the sampling distribution of the difference in sample proportions.

The test statistic for this sample can be calculated as follows:

z = (p1 - p2) / sqrt(p_hat * (1 - p_hat) * (1/n1 + 1/n2))

where p_hat = (x1 + x2) / (n1 + n2), x1 and x2 are the number of successes in the two samples respectively.

Plugging in the given values, we get:

p_hat = (0.254n1 + 0.203n2) / (n1 + n2)
z = (0.254 - 0.203) / sqrt(p_hat * (1 - p_hat) * (1/n1 + 1/n2))

Since the significance level is not given, we cannot determine the critical value for the test. However, we can use the test statistic to calculate the p-value for the test, which is the probability of observing a difference in sample proportions as extreme as the one we observed (or more extreme) under the null hypothesis.

Once we have the p-value, we can compare it to the significance level to make a decision about whether to reject or fail to reject the null hypothesis.

Note: It is important to mention that using the normal approximation without the continuity correction may not always be accurate, especially when the sample sizes are small or the proportion of successes is close to 0 or 1. In such cases, it is recommended to use other methods (such as exact tests or simulation) that do not rely on the normal approximation.

The mean (μ) of the sample is 25 and the standard error (SE) is approximately 1.58.

To find the mean and standard error of a sample, we can use the formulas:

Mean (μ) = population mean = 25
Standard Error (SE) = √(variance / sample size)

Given that the population mean is 25 and the variance is 200, we can calculate the standard error as follows:

Standard Error (SE) = √(200 / 80)
SE = √2.5
SE ≈ 1.58

Therefore, the mean (μ) of the sample is 25 and the standard error (SE) is approximately 1.58.

The best description of the relationship between the y-axis and the line connecting F to F' after reflection over the y-axis is that they are perpendicular to each other.

When a triangle is reflected over the y-axis, its vertices swap their x-coordinates while keeping their y-coordinates the same. Let's consider the points F and F' on the reflected triangle.

The line connecting F to F' is the vertical line on the y-axis because the reflection over the y-axis does not change the y-coordinate. The y-axis itself is also a vertical line.

Since both the line connecting F to F' and the y-axis are vertical lines, they are perpendicular to each other. This is because perpendicular lines have slopes that are negative reciprocals of each other, and vertical lines have undefined slopes.

Therefore, the best description of the relationship between the y-axis and the line connecting F to F' after reflection over the y-axis is that they are perpendicular to each other.

Central angle, θ = (Arc length × 360º)/(2πr) degrees

Sum of Interior angles=180°(n-2)

The angles formulas are used to find the measures of the angles. An angle is formed by two intersecting rays, called the arms of the angle, sharing a common endpoint.

The corner point of the angle is known as the vertex of the angle. The angle is defined as the measure of the turn between the two lines.

There are various types of formulas for finding an angle; some of them are the central angle formula, double-angle formula, etc...

Step-by-step explanation:

7x+3=-17-3x

7x+3x=-17-3

10x=-20

x=-20/10

x=-2

Answer:

\(\boxed{\bold{\huge{\boxed{\sf Yes.}}}}\)

Step-by-step explanation:

=> \(\sf 7x+ 3 = -17-3x\)

Combining like terms

=> \(\sf 7x+ 3x = -17-3\)

=> \(\sf 10x = -20\)

Dividing both sides by 10

=> \(\sf x = -2\)

So, -2 is a solution of the given equation.

the size of the union of the three sets is: |A ∪ B ∪ C| = |A| + |B| + |C| - |A ∩ B| - |A ∩ C| - |B ∩ C| + |A ∩ B ∩ C| = 3  × 24 million - 3 × 1.4 million + 1.2 million ≈ 69 million

A combination is a way of selecting a subset of objects from a larger set without regard to their order. The formula for the number of combinations of n objects taken r at a time is:
C(n, r) = n! / (r! ×  (n - r)!)
where n! means the factorial of n, which is the product of all positive integers up to n. For example, 5! = 5 ×  4 ×  3 ×  2 ×  1 = 120.
To apply this formula to our problem, we first need to count the total number of coins in the pile. Since there are at least 16 of each type, the minimum total is:
16 + 16 + 16 + 16 = 64
But there could be more coins of each type, so the total could be larger than 64. However, we don't need to know the exact number, only that it is large enough to allow us to choose 16 coins from it.
Using the formula for combinations, we can calculate the number of different collections of 16 coins that can be chosen from the pile:
C(64, 16) = 64! / (16! × (64 - 16)!) ≈ 1.1 billion
That's a very large number! It means there are over a billion ways to choose 16 coins from a pile that contains at least 16 of each type.
To answer the second part of the question, we need to count the number of collections that contain at least 3 coins of each type. One way to do this is to use the inclusion-exclusion principle, which says that the number of elements in the union of two or more sets is equal to the sum of their individual sizes minus the sizes of their intersections, plus the sizes of the intersections of all possible pairs, minus the size of the intersection of all three sets, and so on.
In this case, we can consider three sets:
- A: collections with at least 3 pennies
- B: collections with at least 3 nickels
- C: collections with at least 3 dimes
- D: collections with at least 3 quarters
The size of each set can be calculated using combinations:
|A| = C(48, 13) ≈ 24 million
|B| = C(48, 13) ≈ 24 million
|C| = C(48, 13) ≈ 24 million
|D| = C(48, 13) ≈ 24 million
Note that we have to choose 3 coins of each type first, leaving 4 coins to be chosen from the remaining 48 coins.
The size of the intersection of any two sets can be calculated similarly:
|A ∩ B| = C(43, 10) ≈ 1.4 million
|A ∩ C| = C(43, 10) ≈ 1.4 million
|A ∩ D| = C(43, 10) ≈ 1.4 million
|B ∩ C| = C(43, 10) ≈ 1.4 million
|B ∩ D| = C(43, 10) ≈ 1.4 million
|C ∩ D| = C(43, 10) ≈ 1.4 million
Note that we have to choose 3 coins of each type first, leaving 1 coin to be chosen from the remaining 43 coins.
The size of the intersection of all three sets can also be calculated:
|A ∩ B ∩ C| = C(38, 7) ≈ 1.2 million
Note that we have to choose 3 coins of each type first, leaving 1 coin to be chosen from the remaining 38 coins.
