how can you describe range?The range in statistics is the distinction between the greatest and lowest values within a set of data. It is a gauge of variation that reveals the degree to which values within a dataset are dispersed.
You simply take the difference between the two values to determine the range. The range is given by: When the dataset, for instance, has the values 2, 3, 5, 8, et 10, the lowest value is 2, and the highest is 10.
Range = Highest value – Lowest value = 10 – 2 = 8 .The range in this instance is hence 8.
given
The range is the discrepancy between the data set's maximum and minimum values.
The box plot shows that the range is between 40 and 59, with 40 being the smallest value and 59 being the maximum.
Maximum value - Minimum value equals 59 - 40, which equals 19.
You may determine the values of Q1 and Q3 to be roughly 45 and 59, respectively, using the box plot.
IQR = Q3 - Q1 = 59 - 45 = 14
When the IQR is 14 and the range is 19, the answer is:
19 is the range and 14 is the IQR. So, "The range is 19, and the IQR is 14" is the appropriate response.

The correct options for the average speed of both runners are:
B: Candace ran 4 meters per second
F: Candice ran at a faster rate
How to find the average speed between two coordinates?The formula for slope between two coordinates is:
Slope = (y2 - y1)/(x2 - x1)
For Antonio, we take two coordinates from the table to find the average speed.
The coordinates are: (8, 29) and (12, 41)
Thus:
Average speed = (41 - 29)/(12 - 4)
= 12/8 = 1.5 m/s
For candice, we take two coordinates which are:
(10, 42) and (15, 62)
Thus:
Average Speed = (62 - 42)/(15 - 10)
= 20/5
= 4 m/s

In what way are atoms of oxygen most different from autumns of nitrogen? A they have different temperatures B they have different colours C they have different states of matter D they have a different masses
Atoms of oxygen most different from atoms of nitrogen as they have different masses.
A subatomic particle known as an atom is made up of a nucleus composed of protons and neutrons, which is encircled by a swarm of electrons. The atom is the fundamental unit of the chemical elements, and the chemical elements are differentiated from one another by the count of protons present in their atoms. For instance, sodium is any atom that comprises 11 protons, and copper is any atom that includes 29 protons. The isotope of the element is characterized by the number of neutrons. Solid blue crystals can also be a form in which oxygen exists, with molecules that are diatomic.
Interestingly, Priestley was not immediately aware that he had discovered oxygen, and instead believed he had obtained a certain component of air. In a hermetic device, he observed the breakdown of mercury oxide and used a lens to direct sunlight onto the oxide.
In terms of the interaction between nitrogen and oxygen, these substances react in the presence of an electric current. Nitrogen is a stable molecule and does not readily react with other substances.

Enter
Using the given secant line, we know that the required angle ∠a is 15° respectively.
What is secant?A secant in geometry is a line that crosses a curve at least two different points.
The Latin verb secare, which means to cut, is where the word secant originates.
A secant crosses a circle at precisely two points in a case of circle.
The Latin word secant, which means to cut, is used in mathematics to define a line that passes through the points P and Q of any arbitrary curve whose equation is y=f(x).
So, we know that:
c = 55° and b = 25°
And, the formula is:
∠a = c - b/2
Now, insert values as follows:
∠a = c - b/2
∠a = 55 - 25/2
∠a = 30/2
∠a = 15°
Therefore, using the given secant line, we know that the required angle ∠a is 15° respectively.

n=
The professor should select a sample size of at least 247 students to ensure that the 97% confidence interval for the mean amount of time IRSC students spend studying each week has a width of no more than 1.7 hours.
The Sample Size Calculation.To calculate the sample size needed for a confidence interval with a maximum width of 1.7 hours, we need to use the formula:
n = ((z * σ) / E)^2
where:
n is the sample size we need to find
z is the z-score corresponding to the desired confidence level (97% in this case)
σ is the population standard deviation (14.9 hours in this case)
E is the maximum margin of error we want in our confidence interval (1.7 hours in this case)
The z-score corresponding to a 97% confidence level is 1.8808 (which can be found using a z-table or calculator).
Substituting these values into the formula, we get:
n = ((1.8808 * 14.9) / 1.7)^2
n = 246.644
Rounding up to the nearest whole number, we get:
n = 247
Therefore, the professor should select a sample size of at least 247 students to ensure that the 97% confidence interval for the mean amount of time IRSC students spend studying each week has a width of no more than 1.7 hours.

The admission fee at an amusement park is $1.50 for children and $4 for adults. On a certain day, 259 people entered the park, and the admission fees collected totaled $676.00. How many children and how many adults were admitted?
Let us call the number of children "c" and the number of adults "a." Based on the facts provided, we can then construct two equations: c + a = 259 (equation 1) (equation 1).
1.5c + 4a = 676 (2nd equation)
In equation 1, we may solve for one variable in terms of the other:
c = 259 - a
So, in equation 2, substitute this expression for "c":
1.5(259 - a) + 4a = 676
Distribute the 1.5:1:1:1:1:1:1:1:
388.5 - 1.5a + 4a = 676
Merge similar terms:
2.5a = 287.5
Multiply by 2.5:
a = 115
This translates to 115 adults being accepted. We can plug this number back into equation 1 to find "c":

What is the image of the point ( 0 , 1 ) after a rotation of 270 ∘ counterclockwise about the origin?
The image of the point (0,1) after a rotation of 270 degrees counterclockwise about the origin is the point (1,0).
What is trigonometry?
Trigonometry is a branch of mathematics that deals with the relationships between the sides and angles of triangles.
A rotation of 270 degrees counterclockwise about the origin corresponds to a transformation in which every point in the plane is rotated 270 degrees counterclockwise about the origin.
To find the image of the point (0,1) under this transformation, we can use the following formula for a counterclockwise rotation of a point (x,y) about the origin by an angle of θ:
x' = x cos(θ) - y sin(θ)
y' = x sin(θ) + y cos(θ)
Plugging in the values x = 0, y = 1, and θ = 270 degrees, we get:
x' = 0 cos(270°) - 1 sin(270°) = 0 - (-1) = 1
y' = 0 sin(270°) + 1 cos(270°) = 0 + 0 = 0
Therefore, the image of the point (0,1) after a rotation of 270 degrees counterclockwise about the origin is the point (1,0).

In a diagram, angle A and angle B are vertical angles, and angle B is a complementary angle with angle C. If angle A = 22°, write an equation
that you can use to solve for angle C. (2 points)
!! Please help!!!
The value of angle C is 68°.
Describe complementary angles?In geometry, complementary angles are two angles that add up to 90 degrees (a right angle). In other words, when two angles are placed adjacent to each other, and they form a right angle, they are considered complementary angles.
For example, if angle A is 40 degrees, then angle B, which is adjacent to angle A and together they form a right angle, is considered to be a complementary angle. Angle B would be 90 - 40 = 50 degrees.
Complementary angles can be found in many geometric shapes and objects, such as squares, rectangles, and triangles. In a right triangle, the two acute angles (the angles that are not the right angle) are always complementary.
Vertical angles are always congruent, which means that angle B is also 22°.
Since angle B and angle C are complementary, their sum is equal to 90°.
Thus, we can write the equation:
angle B + angle C = 90°
Substituting the known value of angle B, we get:
22° + angle C = 90°
Simplifying the equation, we get:
angle C = 90° - 22°
angle C = 68°
Therefore, the value of angle C is 68°.

bias binding is to be sewn around the edge of a rectangular tablecloth measuring 73 in. by 46 in. if the bias binding comes in packages containing 13 ft of binding, how many packages of bias binding are needed for the tablecloth?
the required number of packages of bias binding for the tablecloth is 2.
As the rectangular tablecloth measures 73 in. by 46 in., the perimeter of the tablecloth can be calculated by the following formula:
Perimeter of the tablecloth = 2(Length + Width)= 2(73 + 46)= 2(119)= 238 inches
Therefore, the length of the bias binding required to sew around the tablecloth will be equal to the perimeter of the tablecloth. The length of the bias binding available in a single package is 13 feet, which is equal to 156 inches.Therefore, the number of packages required can be calculated as:
Number of packages of bias binding required= Length of bias binding required / Length of bias binding in a package= 238 / 156= 1.52
Therefore, 1.52 packages of bias binding will be needed for the tablecloth. However, we cannot purchase a fractional part of a package. Therefore, we need to round up the decimal to the nearest whole number. Hence, 2 packages of bias binding are required for the tablecloth.

Tο find the area οf the οbject, we need tο break it dοwn intο smaller shapes and add up their areas.
First, we can see that the οbject can be divided intο a rectangle with dimensiοns 8 inches by 4 inches (UWVZ), a triangle with base 4 inches and height 6 inches (VXY), and a trapezοid with bases 6 inches and 8 inches, and height 4 inches (WXYU).
The area οf the rectangle is:
A_rectangle = length × width = 8 in × 4 in = 32 square inches
The area οf the triangle is:
A_triangle = 1÷2 × base × height = 1÷2 × 4 in × 6 in = 12 square inches
The area οf the trapezοid is:
A_trapezοid = 1÷2 × (base1 + base2) × height = 1÷2 × (6 in + 8 in) × 4 in = 28 square inches
Therefοre, the tοtal area οf the οbject is:
A_οbject = A_rectangle + A_triangle + A_trapezοid
= 32 square inches + 12 square inches + 28 square inches
= 72 square inches
Therefοre, the clοsest οptiοn tο the actual area οf the οbject is D. 64 square inches.

Find the equation of the exponential function that goes through the points (0,4) and (4,0.25).
The answer of the given question based on the exponential function is the exponential function that goes through the points (0,4) and (4,0.25) is: f(x) = 4(0.5)ˣ.
What is Equation?An equation is a statement that two expressions are equal. It contains an equal sign (=) which separates the two expressions, and it can include variables, constants, and mathematical operations such as addition, subtraction, multiplication, division, exponents, and roots.
The general form of exponential function is:
f(x) = a(b)ˣ
where a is the initial value, b is the base, and x is the independent variable.
We can use the two given points to form a system of equations and solve for the values of a and b.
Using the point (0,4):
f(0) = a(b)⁰ = a = 4
Using the point (4,0.25):
f(4) = a(b)⁴ = 0.25
Now we can substitute a = 4 into the second equation and solve for b:
4(b)⁴ = 0.25
(b)⁴ = 0.25/4 = 1/16
b = (1/16)⁽¹/⁴⁾ = 0.5
Therefore, the exponential function that goes through the points (0,4) and (4,0.25) is: f(x) = 4(0.5)ˣ

5,7,9,11,13...
find the 25th Term
By answering the presented question, we may conclude that Therefore, the 25th term of the arithmetic sequence is 53.
What is Sequences?In mathematics, a sequence is an ordered list of items. Elements can be numbers, functions, or other mathematical objects. A series is commonly expressed by putting the phrases in parentheses and separating them with commas. A natural number series, for example, can be denoted as: (1, 2, 3, 4, 5, ...) Similarly, the even number series is labelled as follows: (2, 4, 6, 8, 10, ...) A series can be finite or infinite depending on whether it has a finite or infinite number of words.
To find the 25th term,
an = a1 + (n - 1)d
In this case, a1 = 5 and d = 2. Plugging these values into the formula, we get:
a25 = 5 + (25 - 1)2
a25 = 5 + 48
a25 = 53
Therefore, the 25th term of the arithmetic sequence is 53.

Solve the following quadratic function by utilizing the square root method.
Simplify your answer completely.
f(x) = 25×2-81
The solutions to the quadratic function f(x) = 25x^2 - 81 are x = 9/5 and x = -9/5.
Quadratic function solutionFirst, we need to rewrite the function in standard quadratic form:
f(x) = 25x^2 - 81
To solve this quadratic function using the square root method, we want to isolate the x^2 term and divide both sides by the coefficient of x^2, which is 25:
25x^2 - 81 = 0
25x^2 = 81
x^2 = 81/25
Taking the square root of both sides, we get:
x = ±(9/5)
Therefore, the solutions to the quadratic function f(x) = 25x^2 - 81 are x = 9/5 and x = -9/5.
