The coordinates of the center is (32, 40.5).

length of the radius of the circle is 73 units.

The coordinates of the center is solved using the formula for midpoints expressed as

Midpoint x-coordinate = (x₁ + x₂) / 2

Midpoint y-coordinate = (y₁ + y₂) / 2

Plugging in the values:

x₁ = 8 and y₁ = 13

x₂ = 56 and y₂ =68

Midpoint x-coordinate

= (8 + 56) /2

= 64/2

= 32

Midpoint y-coordinate

= (13 + 68) /2

= 81/ 2

= 40.5

distance formula will be used to find the length of the radius of the circle

d = √[(x₂ - x₁)² + (y₂ - y₁)²]

Plugging in the values:

= √[(56 - 8)² + (68 - 13)²]

= √(48² + 55²)

= √(2304 + 3025)

= √5329

The equation of the parabola with focus (2,5) and directrix x=18 is (x - 18)² + (y - 5)² = (y - (5 + (18 - 2) / 2))².

A parabola is a conic section, the intersection of a right circular conical surface and a plane parallel to a generating

straight line of that surface.

The focus of a parabola is a fixed point on the interior of a parabola used in the formal definition of the curve.

The directrix is a straight line perpendicular to the axis of symmetry and placed symmetrically with respect to the focus.

The axis of symmetry is the line through the focus and perpendicular to the directrix.

The vertex of a parabola is the point where its axis of symmetry intersects the curve. It is the point where the parabola changes direction or "opens

up" or "opens down.

The directrix is a fixed straight line used in the definition of a

parabola. It is placed such that it is perpendicular to the axis of symmetry and at a distance from the vertex equal to the

distance between the vertex and focus. It is the line that is equidistant to the focus and every point on the curve.Here's

the solution to the given problem:

The distance between the directrix and the focus is equal to p = 16 (since the directrix is x = 18, the parabola opens to the left, so the distance is measured horizontally)

The vertex is (h,k) = ((18+2)/2,5) = (10,5)

Then we can use the following formula: (x - h)² = 4p(y - k)

Substitute the vertex and the value of p. (x - 10)² = 64(y - 5)

Expand and simplify. (x - 10)² + (y - 5)² = 64(y - 5)

The equation of the parabola is (x - 10)² + (y - 5)² = 64(y - 5).

An interval within which we expect 95% of all x 's to fall can be defined for any population by applying the Central Limit Theorem.

The Central Limit Theorem states that for a large sample size, the sample mean will be approximately normally distributed, regardless of the underlying distribution of the population.

This means that we can use the properties of the normal distribution to make probabilistic statements about the sample mean.

Specifically, we can construct a confidence interval for the population mean by calculating the sample mean and the standard error of the mean.

If we assume that the population mean is normally distributed, we can use the properties of the normal distribution to calculate the probability that the population mean falls within a certain interval.

For example, a 95% confidence interval for the population mean represents the range of values that we are 95% confident contains the true population mean.

Answer:

length = 75 ft and width = 25 ft

Step-by-step explanation:

Let W = width of rectangle

Let L = length of rectangle

Area of a rectangle = L x W

Perimeter of a rectangle = 2L + 2W

Therefore, if the perimeter is 200 ft then:

2L + 2W = 200

2(L + W) = 200

    L + W = 100

           L = 100 - W

If the Area is 1875 ft² then:                             1875 = L x W

Substitute the equation for L found above:  1875 = (100 - W) x W

Expand the brackets:                                    1875 = 100W - W²

Subtract 1875 from both sides:  100W - W² - 1875 = 0

Swap signs:                                W² - 100W + 1875 = 0

Factorize:                                       (W - 25)(W - 75) = 0

Therefore, W = 25 or 75

If W = 25, then L = 100 - 25 = 75

If W = 75, then L = 100 - 75 = 25

Therefore, as length > width, length = 75 ft and width = 25 ft

Step-by-step explanation:

There is a common difference d between consecutive terms, that is

d = - 3 - 3 = - 9 - (- 3) = - 15 - (- 9) = - 6

This indicates the sequence is arithmetic with explicit formula

\(a_{n}\) = a₁ + (n - 1)d

True. Recursion is often necessary to solve certain types of problems that exhibit a recursive structure or require repeated subproblem solving.

Recursion is a programming technique where a function calls itself in its own definition. It allows for the decomposition of complex problems into smaller, more manageable subproblems that can be solved recursively. Recursion is particularly useful when problems exhibit a recursive structure, such as tree traversal, backtracking, or divide-and-conquer algorithms.

For example, problems like computing the factorial of a number, calculating Fibonacci numbers, or traversing a binary tree can be elegantly and efficiently solved using recursion. These problems can be broken down into smaller instances of the same problem until a base case is reached, and then the solutions are combined to solve the original problem.

However, it's worth noting that not all problems require recursion for their solution. There are alternative approaches, such as iterative loops or dynamic programming, which can be used depending on the problem's characteristics and requirements.

It is not possible to reach the top of the ladder to the edge of the roof.

We can solve this problem using the Pythagorean theorem, which states that for a right triangle, the sum of the squares of the two shorter sides is equal to the square of the length of the hypotenuse (the longest side).

In this case, the ladder is the hypotenuse of a right triangle, and the distance from the base of the ladder to the house and the distance from the top of the ladder to the edge of the roof are the two shorter sides.

Let x be the distance from the top of the ladder to the edge of the roof. Then, we can write:

\(10^{2}\) = \((1.5)^{2}\) + \(x^{2}\) + \(12^{2}\)

Simplifying and solving for x, we get:

100 = 2.25 +\(x^{2}\) + 144

\(x^{2}\) = 100 - 2.25 - 144

\(x^{2}\) = -46.25

Since x represents a distance, which must be positive, this means that there is no solution to the equation. Therefore, it is not possible for Sammy to reach the edge of the roof with his 10-foot ladder while keeping the base of the ladder at least 1.5 feet from the base of the house.

7 cookies

Step-by-step explanation:

We have 3 brothers

First , Second, Third

Let the total number cookies be represented by A

1 cookie = 1

Working backwards, we start from the third brother

If we work backwards

It means he gave everything away

We start from the youngest

He was given 1/2 of what was left and 1/2 a cookie

This means,

1/2 + 1/2 = 1

The second brother

He got half of what is left and 1/2 a cookies

Half of what is left from brother

= What the youngest brother got + 1/2 + 1/2 a cookie

= 1 + 1/2 + 1/2

= 1.5 + 1/2

= 2 cookies

For the first brother

He got 1/2 of the cookies + 1/2 cookie

= 1.5 × 2 + 1/2 + 1/2 cookies

= 3 1/2 + 1/2

= 4 cookies

The first brother got 4 cookies

The second brother got 2 cookies

The third broth got 1 cookies

Based on the information given, the total number of cookies will be 7 cookies.

Based on the information given, the number of cookies that was given to the youngest child will be:

= 1/2 + 1/2 = 1

The number of cookies that the second brother will get will be:

= 1 + 1/2 + 1/2

= 2

Therefore, the number of cookies that the first brother got will be:

= 3 1/2 + 1/2

Step-by-step explanation:

The diameter of the circle is approximately 60 inches.

To explain further, we can use the formula relating the central angle of a sector to the length of its intercepted arc. The formula states that the length of the intercepted arc (A) is equal to the radius (r) multiplied by the central angle (θ) in radians.

In this case, we are given the central angle (225 degrees) and the length of the intercepted arc (30π inches).

To find the diameter (d) of the circle, we need to find the radius (r) first. Since the length of the intercepted arc is equal to the radius multiplied by the central angle, we can set up the equation 30π = r * (225π/180). Simplifying this equation gives us r = 20 inches.

The diameter of the circle is twice the radius, so the diameter is equal to 2 * 20 inches, which is 40 inches. Therefore, the diameter of the circle is approximately 60 inches.

In summary, by using the formula for the relationship between central angle and intercepted arc length, we can determine the radius of the circle. Doubling the radius gives us the diameter, which is approximately 60 inches.

(a) True. The parameters in a linear probability model can be interpreted as measuring the change in the probability that y = 1 due to a one-unit increase in an explanatory variable.

In a linear probability model, the dependent variable (y) takes on binary values, typically 0 or 1, representing two possible outcomes.

The linear probability model assumes a linear relationship between the explanatory variables and the probability of the dependent variable being equal to 1.

The parameters in the linear probability model represent the effects of the explanatory variables on the probability of y being equal to 1.

Specifically, the coefficient associated with an explanatory variable can be interpreted as the change in the probability that y = 1 for a one-unit increase in that variable, holding other variables constant.

For example, if we have a linear probability model with an explanatory variable X and the corresponding coefficient is β, then a one-unit increase in X would lead to a β increase in the probability that y = 1, all else being equal.

However, it's important to note that the linear probability model has certain limitations.

Since probabilities are bounded between 0 and 1, the predicted probabilities from the model may exceed this range.

Additionally, the model assumes constant effects across all levels of the explanatory variables, which may not always hold true in practice.

Despite these limitations, the interpretation of the parameters in a linear probability model as the change in the probability of y = 1 due to a one-unit increase in an explanatory variable is generally valid.
