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.

10. A bag contains 3 red marbles, 7 white marbles, and 5 blue marbles. You draw 3 marbles, replacing each one before drawing the next. What is the probability of drawing a red, then a blue, and then a white marble?
the probability of drawing a red, then a blue, and then a white marble is [tex]=\frac{7}{225}[/tex]
To find probability, we take the number of ways the specific event can occur and divide it by the number of ways any event can occur.
The probability of drawing a red marble is: (of red marbles) / (total # of marbles) = 3/(3 + 7 + 5) = 3÷15 = 1÷5.
The probability of drawing a blue marble is: ( of blue marbles) / (total # of marbles) = 5/(3 + 7 + 5) = 5÷15 = 1÷3.
The probability of drawing a white marble is: ( of white marbles) / (total # of marbles) = 7/(3 + 7 + 5) = 7÷15.
Now, we want these events to all to occur for us. So, we must multiply them by each other: (1/5) * (1/3) * (7/15) [tex]=\frac{7}{225}[/tex]

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).

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":
c + 115 = 259
c = 144
As a result, 144 youngsters were hospitalised.

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°.

Answer:
I'm sorry your paper is not clear please retake the picture and again attached it
Step-by-step explanation:
A professor would like to use a 97% confidence interval to estimate the mean amount of time IRSC students
spend studying each week. The professor knows that distribution of time spent studying each week by IRSC
students is normally distributed with a standard deviation of 14.9 hours.
How large a sample should the professor select to ensure the confidence interval has a width of no more
than 1.7 hours. Round the solution up to the nearest whole number.
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.

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.

what is cylinder ?
A cylinder is a three-dimensional shape that consists of two parallel circular bases connected by a curved surface. It can be thought of as a tube or a can, and is a common shape found in many everyday objects such as soda cans, tubes, and pipes.
In the given question,
To find the missing dimension (diameter) of the cylinder, we can use the formula for the volume of a cylinder:
V = πr²h
where V is the volume of the cylinder, r is the radius of the cylinder, and h is the height of the cylinder.
Since the diameter (D) is twice the radius (r), we can also write:
V = π(D/2)²h
Simplifying this expression, we get:
V = πD²h/4
Multiplying both sides by 4/πh, we get:
D² = 4V/(πh)
Taking the square root of both sides, we get:
D = 2√(V/πh)
Substituting the given values, we get:
D = 2√(7433 in.³/π(14 in.))
D ≈ 18.9 in.
Therefore, the missing dimension (diameter) of the cylinder is approximately 18.9 inches, rounded to the nearest tenth.

A trapezoid, also known as a trapezium in some countries, is a two-dimensional geometric shape with four sides. It is a quadrilateral that has at least one pair of parallel sides, which are called bases.
Let's start by labeling the sides of the isosceles trapezoid as follows:
The shorter base: b1 = 6.3 mm
The longer base: b2 = 16.1 mm
The two equal sides: s
We know that the perimeter P of the trapezoid is given by:
P = b1 + b2 + 2s
Substituting the values we have, we get:
45 mm = 6.3 mm + 16.1 mm + 2s
Simplifying this equation, we get:
22.6 mm = 2s
Dividing both sides by 2, we get:
s = 11.3 mm
Therefore, the length of the two equal sides of the isosceles trapezoid is 11.3 millimeters.

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.

what are the vertices of this ellipse? graph (-4, 2) and (4, 2) (2 , 2) and (2 , 2) (-5, 5) and (-5, -1) (-9, 2) and (-1, 2)
The vertices of the ellipse are (-4,2) and (4,2), since these points lie on the major axis of the ellipse which is horizontal.
Two of the focuses given in the issue, (−4,2) and (4,2), are both situated on a similar even line. This implies that the significant hub of the oval should be level. Two different focuses given in the issue, (2,2) and (- 9,2), are likewise situated on this level line. Thusly, the focal point of the oval is the midpoint between the focuses (- 4,2) and (4,2), which is (0,2).
The other two focuses given in the issue, (−5,5) and (−5,−1), are situated on an upward line that goes through the focal point of the oval. This implies that the minor pivot of the oval should be vertical.
The vertices of the oval are the places where the significant hub meets the circle. Since the significant hub goes through the focuses (−4,2) and (4,2), the vertices of the oval are (- 4,2) and (4,2).
In this way, the vertices of the oval are (- 4,2) and (4,2).

Mia is buying a computer monitor that is 18
inches tall and has a distance of 30 inches
between opposite corners. What is the width of
Mia's new monitor?
inches
This problem is a Pythagorean theorem word problem
Answer:
To solve this problem, we can use the Pythagorean theorem, which states that the sum of the squares of the two legs of a right triangle is equal to the square of the hypotenuse.In this case, the height of the monitor is one leg of the right triangle, and the width of the monitor is the other leg. The distance between opposite corners is the hypotenuse.Let w be the width of the monitor in inches. Then we have:w^2 + 18^2 = 30^2Simplifying and solving for w, we get:w^2 + 324 = 900
w^2 = 576
w = 24Therefore, the width of Mia's new monitor is 24 inches.

Sandra and Karen are playing a game of cards with a standard deck of playing cards. Sandra deals Karen a red seven.
The probability that Karen’s second card will be a black card is 26/51.
What is a probability?Probability is simply the likelihood of something occurring. When we are uncertain about the outcome of an event, we can discuss the probabilities of various outcomes—how likely they are.
Let R represent the red cards and B represent the black cards.
We are given that a standard deck of playing cards consists of 52 cards. There are 26 black and 26 red cards in a playing deck.
The probability of the first card being red:
P(First R) = [tex]26/52[/tex]
