There are seven lines of symmetry in a heptagon. In a heptagon, the sides and angles are equal. Each vertex and the center of a regular heptagon are where the line of symmetry crosses.
What is Reflectional Symmetry ?
Any symmetry with regard to a reflection is referred to as reflection symmetry, line symmetry, mirror symmetry, or mirror-image symmetry. In other words, a figure with reflectional symmetry does not alter when it is reflected. There is a line/axis of symmetry in 2D and a plane of symmetry in 3D. When a form or pattern is mirrored in a line of symmetry or a mirror line, this is known as reflective symmetry. The reflected form will have the same size, distance from the mirror line, and other characteristics as the original shape. When a figure can be split into two equal halves that match, it has line symmetry or reflection symmetry.
If a figure can be reflected over a line and retain its original appearance, it possesses reflection symmetry. If a figure can be altered while maintaining its appearance, it possesses symmetry.

Find sn for the arithmetic series where a1=−20 , n=25 , an=148
The value of the sum of the series is 160
How to determine the sum of the seriesIn an arithmetic series, the sum of the first "n" terms (Sn) is given by the formula:
Sn = n/2 * (a1 + an)
Where "a1" is the first term and "an" is the nth term.
In this series, n = 25, a1 = -20, and an = 148.
Plugging these values into the formula, we get:
Sn = 25/2 * (-20 + 148)
= 25/2 * 128
= 25 * 64
= 1600
So, the sum of the first 25 terms of the arithmetic series is 1600.

y^2(4-y^2) critical points
The critical values of the given function are 0, +2, and -2.
According to the question
Given function f(x) = y^2(4-y^2)
Setting the partial derivatives of the function y2(4-y2) to zero and solving for y will reveal where the function's crucial points are.
The partial derivatives of y^2(4-y^2) with respect to y are:
⇒ d/dy (y^2) = 2y
⇒ d/dy (4-y^2) = -2y
⇒ d/dy (y^2(4-y^2)) = 2y(-2y) + 2(y^2)
⇒ -4y^2 + 4y^2 = 0
Setting the partial derivative equal to zero:
-4y^2 + 4y^2 = 0
Solving for y:
y = 0 or y = ±2
The critical values are therefore y = 0 and y = 2. Using the second derivative test or by examining the behavior of the function close to these locations, these key points can be categorized as local minima, local maxima, or inflection points.

3 (q − 7) = 27
EXPLAIN PLEASE AND TYSM
Answer: q = 16
Step-by-step explanation:
When given the equation 3(q - 7) = 27, you would solve for the variable.
The variable in this equation is q, so we need to isolate the variable.
Solving process:
3(q - 7) = 27
lets distribute, due to the orders of PEMDAS.
PEMDAS stands for: Parenthesis, Exponents, Multiplication, Division, Addition, and Subtraction.
3(q - 7) = 27
distributing is multiplying the number correlated outside of the parenthesis with the inside components.
3q - 21 = 27
lets add 21 to both sides
3q = 48
now lets divide by 3 (we are trying to get q by itself)
q = 16
----
To check if your solution is correct, you replace the value (16) of the variable (q) within the original equation:
3 (16 − 7) = 27
Following PEMDAS you get:
3(9) = 27
27 = 27 (meaning that the solution is correct)

having.
The 95% confidence interval for the mean number of shoes owned by female students is (95.58, 195.14).
Calculate the sample mean:
Total number of shoes = 45+31+3125+62+15+29+27+28+35+18+55+18+39+28+35+44+18+10+55+50+40+38+22+16 = 3634
Sample mean = 3634/25 = 145.36
Calculate the standard deviation:
Standard deviation = √[(45-145.36)² + (31-145.36)² + (3125-145.36)² + … + (16-145.36)²]/24 = 586.33
Calculate the margin of error:
Margin of error = 1.96∗586.33/√25 = 49.78
Calculate the 95% confidence interval:
Lower bound = 145.36 - 49.78 = 95.58
Upper bound = 145.36 + 49.78 = 195.14
Since the sample mean is not an integer, we must round the lower and upper bounds to the nearest integer, which gives us (29.73, 40.27) as the 95% confidence interval for the mean number of shoes owned by female students.

find the angles between the planes in exercises 47 and 48. 47. x y = 1, 2x y - 2z = 2
47.) The angle between the plane is 0 degrees.
48.) The angle between the plane is 180 degrees.
What is the angle between the plane?
To find the angle between two planes, we need to find the normal vectors of each plane and then find the cosine of the angle between the normal vectors using the dot product.
First, let's find the normal vectors for the two planes:
Plane 1: x + y = 1
The normal vector for this plane can be found by taking the coefficients of x, y, and z and forming a vector:
n1 = ⟨1, 1, 0⟩
Plane 2: 2x + y - 2z = 2
The normal vector for this plane can be found in the same way:
n2 = ⟨2, 1, -2⟩
Next, we will find the cosine of the angle between the normal vectors using the dot product:
cosθ = (n1 • n2) / (|n1| * |n2|)
where |n1| and |n2| are the magnitudes of the normal vectors.
Calculating the dot product and magnitudes:
n1 • n2 = 1 * 2 + 1 * 1 + 0 * -2 = 3
|n1| = sqrt(1^2 + 1^2 + 0^2) = sqrt(2)
|n2| = sqrt(2^2 + 1^2 + (-2)^2) = sqrt(9)
Substituting into the formula:
cosθ = 3 / (sqrt(2) * sqrt(9)) = 3 / (3) = 1
Since cosθ = 1, θ = 0, so the angle between the two planes is 0 degrees or a coincident plane.
Next, let's find the normal vectors for the two planes:
Plane 1: 5x + y - z = 10
The normal vector for this plane can be found by taking the coefficients of x, y, and z and forming a vector:
n1 = ⟨5, 1, -1⟩
Plane 2: x - 2y + 3z = -1
The normal vector for this plane can be found in the same way:
n2 = ⟨1, -2, 3⟩
Next, we will find the cosine of the angle between the normal vectors using the dot product:
cosθ = (n1 • n2) / (|n1| * |n2|)
Calculating the dot product and magnitudes:
n1 • n2 = 5 * 1 + 1 * (-2) + -1 * 3 = -3
|n1| = sqrt(5^2 + 1^2 + (-1)^2) = sqrt(27)
|n2| = sqrt(1^2 + (-2)^2 + 3^2) = sqrt(14)
Substituting into the formula:
cosθ = -3 / (sqrt(27) * sqrt(14)) = -3 / (3 * sqrt(2)) = -sqrt(2) / sqrt(2) = -1
Since cosθ = -1, θ = 180 degrees, so the angle between the two planes is 180 degrees, or perpendicular.
Hence,
47.) The angle between the plane is 0 degrees.
48.) The angle between the plane is 180 degrees.

Hz (Hertz) is a unit of frequency, which measures the number of events or occurrences of a certain phenomenon per second. In this case, the tape timer creates 28 dots per second, which means that the frequency of dot creation is 28 Hz.
To find the time interval between 3 successive dots, we need to calculate the time it takes for the tape timer to create 3 dots. This can be done by dividing the total time by the number of dots created.
Since the tape timer creates 28 dots per second, the time interval between 3 dots can be calculated as follows:
Time interval = 1 second / 28 dots = 1/28 seconds
So, the time interval between 3 successive dots created by the tape timer is 1/28 seconds, which is the amount of time that elapses between the creation of each dot.

Round to the nearest tenth. This is a multi-step problem so do not round until the final answer.
The segment drawn from the apex to the edge of the circular base is __ units.
The slant height of the right cone is 24.2 units, rounded to the nearest tenth.
What is the Pythagorean Theorem?
The Pythagorean theorem is a mathematical theorem that states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. It can be expressed as c² = a²+ b².
The slant height of a right cone can be found by using the Pythagorean Theorem. The radius of the circular base is half the diameter, which is 6/2 = 3 units. The volume of the cone can be found using the formula:
V = (π/3)r²h
Where r is the radius, and h is the height of the cone. Plugging in the given values, we have:
72π = (π/3)r²h
72π = (π/3)3²h
72π = (π/3)9h
72π = 3πh
24 = h
Using the Pythagorean Theorem, we can find the slant height as follows:
c² = a² + b²
Where a and b are the height and radius of the cone, and c is the slant height. Plugging in the values we have:
c² = 24² + 3²
c² = 576 + 9
c² = 585
c = 24.2
Hence, the slant height of the right cone is 24.2 units, rounded to the nearest tenth.

to study the diameter of the trunks of white pine in a national forest, 50 trees were selected by using random latitude/longitude coordinates. if a point fell within the canopy of a tree, the tree was included in the sample. if not, another random location was generated. what error is likely to result from this study design?
The study design of selecting 50 trees using random latitude/longitude coordinates may result in sampling error and measurement error, which could affect the accuracy of the results.
The error that is likely to result from this study design is known as "sampling error" because the sample of 50 trees is not necessarily representative of the entire population of white pine trees in the national forest as these trees were selected by chance.
If the sample of 50 trees were selected from a particular area of the forest where the trees were smaller in diameter, the study results would not accurately reflect the average diameter of all the white pine trees in the forest.
Moreover, there is a possibility of measurement error if the diameter of the trunks were not measured consistently. This could also contribute to the overall error in the study results.

Solve the triangle: If it is not possible, say so.
Therefore , the solution of the given problem of triangle comes out to be it is unsolvable as the all the information is not given option A is correct.
What does a triangle signify exactly?Polygons include triangles since they have four sides or more. It has a simple, geometric shape. The letters ABC make up a triangle, which is a square angle. Euclidean geometry results in a single rectangle or square so when sides remain not coincident. Because they have 3 components and three corners, triangles are polygons. A triangle's corners are where its three sides meet. The total of the angles in a triangle is 180 degrees.
Here,
Given :
=> α = 60°
=> β = 60°
=> γ = 60°
To solve the triangle we need to know the angles,

An airplane i carrying 90
paenger, which i 67
of the capacity of the airplane. What i the capacity of the airplane?
The capacity of the airplane is 105 passengers.
Since 90 passengers is to 6/7 of the capacity, then 90/6 people is 1/7 of the capacity. And, 90 / 6 = 15
So, 15 people is 1/7 of the capacity. It means, the full capacity is 7/7.
Full capacity = 15 * 7 = 105
Hence, the capacity of the airplane is 105 passengers.
What is capacity of passenger?Capacity of passengers are the total number of seats and berths and the total number of authorized standing places which available in a passenger vehicle when doing the service for what it is intended.

How can you use a protractor to prove that AB and CD are parallel?
How can you use paper folding to prove that AB and CD are parallel?
Lines AB and CD are parallel to each other because the lines make the same angle as the transversal line.
What are parallel lines?When the distance between the lines is constant then the lines are called parallel lines. The lines do not intersect when they are separated from each other. And the slope of the lines is equal.
Let the transversal line be EF to line AB and CD.
Line AB and line CD make the same angle as the transversal line. Then we can say that the lines AB and CD are parallel to each other.
