Will is therefore more likely to choose a blue tile before choosing a yellow tile.

The likelihood or possibility of an event happening is measured by probability. It is represented by a number in 0 and 1, with 0 denoting an impossibility and 1 denoting a certainty. By dividing total number of favourable possibilities by the total number of potential outcomes, one can determine the probability of an occurring. In other respects, it is the proportion between the amount of alternative outcomes to the number of possible ways the event could happen. In many fields, including statistics, mathematics, physics, economics, and the social sciences, probability is used to create predictions and well-informed judgements based on the likelihood that events will occur.

given

We must take into account the likelihood of each event and then combine them together in order to get the probability of choosing a blue tile first, followed by a yellow tile.

Will picks blue first, then yellow, therefore P(Will) = (6/15) * (5/15) = 2/15

The likelihood that Joan will first choose a blue tile is the same as before: 6/15.

Joan picking a yellow tile on her second pick thus has a 5/14 chance of doing so. Hence, the likelihood that Joan will choose a blue tile first, followed by a yellow tile, is:

P(Joan chooses yellow first, then blue) = (6/15) * (5/14) = 3/35

Will is therefore more likely to choose a blue tile before choosing a yellow tile.

To solve this problem, we can use a Venn diagram to represent the information given.

Total students surveyed = 560

395 like superheroes from either company

240 prefer DC superheroes

358 do not like Marvel superheroes

To find how many students did not like DC superheroes, we need to find the number of students who do not fall into the DC circle:

Students who do not like Marvel superheroes = 358

Students who like both DC and Marvel superheroes = (395 - 240) = 155

Students who like Marvel superheroes only = ?

Students who like DC superheroes only = (240 - 155) = 85

To find how many students like Marvel superheroes, we need to find the number of students who fall into the Marvel circle:

Students who do not like DC superheroes = ?

Students who like both DC and Marvel superheroes = 155

Students who like Marvel superheroes only = ?

Students who like DC superheroes only = 85

To find how many students like both DC and Marvel superheroes, we can use the information we already have:

Students who like both DC and Marvel superheroes = 155

To find how many students like DC but not Marvel superheroes, we can use the information we already have:

Students who like DC superheroes only = 85

To find how many students like Marvel but not DC superheroes, we can use the information we already have:

Students who like Marvel superheroes only = (358 - 155) = 203

Finally, to find how many students do not like the DC or Marvel superheroes, we need to find the number of students who do not fall into either circle:

Students who do not like DC superheroes = ?

Students who like both DC and Marvel superheroes = 155

Students who like Marvel superheroes only = 203

Students who like DC superheroes only = 85

We can now use the formula for the total number of students surveyed to find the number of students who do not like DC or Marvel superheroes:

Total students surveyed = Students who do not like DC superheroes + Students who like both DC and Marvel superheroes + Students who like Marvel superheroes only + Students who like DC superheroes only

560 = Students who do not like DC superheroes + 155 + 203 + 85

Students who do not like DC superheroes = 117

Similarly, we can use the same formula to find the number of students who like Marvel superheroes:

560 = Students who do not like DC superheroes + 155 + Students who like Marvel superheroes only + 85

Students who like Marvel superheroes = 203 + 155

(b) The measure of angle CDE is 128°

From the question, we are to determine the measure of the unknown angles

First, let us produce line BCD to Z

Then,

m ∠FDZ = m ∠BCP

From the given diagram

m ∠BCP + 148° = 180° (Sum of angles on a straight line)

m ∠BCP = 180° - 148°

m ∠BCP = 32°

Therefore,

m ∠FDZ = 32°

Also,

m ∠EDZ = 84° - m ∠FDZ

m ∠EDZ = 84° - 32°

m ∠EDZ = 52°

m ∠CDE + m ∠EDZ = 180° (Sum of angles on a straight line)

m ∠CDE + 52° = 180°

m ∠CDE = 180° - 52°

m ∠CDE = 128°

m ∠ABQ + m ∠QBD = m ∠CDE (Alternate interior angles)

m ∠ABQ + 74° = 128°

To find the center and radius of the circle, we need to rewrite the equation in standard form, which is: (x - h)^2 + (y - k)^2 = r^2 where (h, k) is the center of the circle and r is the radius. To rewrite the given equation in standard form, we need to complete the square for both x and y terms. Let's start with the x terms: x^2 - 12x = -(y^2 - 2y + 33) To complete the square for x, we need to add and subtract (12/2)^2 = 36: x^2 - 12x + 36 - 36 = -(y^2 - 2y + 33) (x - 6)^2 - 36 = -(y^2 - 2y + 33) Now

To find the center and radius of the circle given by the equation:

x^2 + y^2 -12x + 2y + 33 = 0

We need to rewrite the equation in standard form, which is:

(x - h)^2 + (y - k)^2 = r^2

where (h, k) is the center of the circle and r is the radius.

To do this, we need to complete the square for both x and y terms by adding and subtracting appropriate terms inside the parentheses.

(x^2 - 12x) + (y^2 + 2y) + 33 = 0

To complete the square for x terms, we need to add (12/2)^2 = 36 inside the first set of parentheses and subtract it from the equation:

(x^2 - 12x + 36) + (y^2 + 2y) + 33 - 36 = 0

(x - 6)^2 + (y^2 + 2y) - 3 = 0

To complete the square for y terms, we need to add (2/2)^2 = 1 inside the second set of parentheses and subtract it from the equation:

(x - 6)^2 + (y^2 + 2y + 1) - 4 = 0

(x - 6)^2 + (y + 1)^2 = 4

Now we can see that the equation is in standard form, where (h, k) = (6, -1) is the center of the circle, and r^2 = 4, so the radius is r = 2.

Therefore, the center of the circle is (6, -1) and the radius is 2.

Step-by-step explanation:

The total number of marbles in the bag is 3+2+4+1=10.

The probability of pulling a red marble on the first draw is 3/10, since there are 3 red marbles out of 10 total marbles.

Since we are not replacing the marble after each draw, the probability of pulling another red marble on the second draw decreases slightly. After one red marble has been drawn, there are only 2 red marbles left out of 9 total marbles. So the probability of pulling a second red marble is 2/9.

Therefore, the theoretical probability of pulling two red marbles without replacement is:

P(Red, Red) = P(Red on first draw) x P(Red on second draw, given that the first marble was red)

= 3/10 x 2/9

= 1/15

So the theoretical probability of pulling a red marble without replacement is 1/15 or approximately 0.067 or 6.7%.

The value of the theoretical probability of pulling a red marble without replacement is,

= 3/10

= 0.3

= 30%

The term probability refers to the likelihood of an event occurring. Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.

Given that;

A bag has 3 red marbles, 2 blue, 4 green and 1 yellow.

Hence, Total marbles = 3 + 2 + 4 + 1 = 10

Thus, The value of the theoretical probability of pulling a red marble without replacement is,

P = Desired Outcomes / Total number of outcomes.

P = 3 / 10

P = 0.3

P = 30%

Therefore, the angle measure indicated 110° that is option A.

An angle is the measure of the amount of rotation between two intersecting lines or planes. It is defined as the space between two intersecting lines or planes measured in degrees, radians, or other units of angular measurement. Angles are often represented by a symbol that looks like a small arc, with three letters labeling the points that define the angle, such as "ABC." The vertex of an angle is the point where the two lines or planes intersect, and the sides of an angle are the two rays that extend from the vertex. Angles are used in geometry, trigonometry, and other mathematical fields to measure and analyze the relationships between shapes and objects.

Here,

Since sector PF has a measure of 90 degrees, then angle PAF must also have a measure of 90 degrees since it is an inscribed angle that intercepts the same arc.

To find the angle measure of QSR, we first need to find the measure of angle QPR.

Since sector PF is a 90 degree sector and line QR is tangent to the circle at point R, we know that angle QRP is a right angle (90 degrees).

Similarly, since sector QR is a 150 degree sector and line PS is tangent to the circle at point S, we know that angle QPS is a right angle (90 degrees).

Therefore, angle QPR + angle QPS = 90 + 90 = 180 degrees.

Since angle QPS and angle QRP share ray QR, they are adjacent angles.

So, angle QSR = 360 - (angle QPR + angle QPS)

= 360 - 180 -70

= 110 degrees

Therefore, the measure of angle QSR is 110 degrees, which is equivalent to a straight line.

For two triangles to be similar by side-angle-side (SAS) similarity, they must have two pairs of proportional sides and an included angle that is congruent between them.

How to prove similarity?

Let's consider triangles FGH and JKL. By inspection, we can see that FG is proportional to JK and GH is proportional to KL. Additionally, the included angles ∠FGH and ∠JKL are congruent, which means that we have two pairs of proportional sides and an included congruent angle.

Therefore, we can conclude that triangles FGH and JKL are similar by SAS similarity. This means that the corresponding angles of the two triangles will be congruent, and the corresponding sides will be in proportion to each other.

We can use this similarity to find missing side lengths or angles. For example, if we know the length of FG in triangle FGH and the length of JK in triangle JKL, we can use their proportionality to find the length of GH or KL. Similarly, we can use the congruent angles to find other missing angles in either triangle.

It is important to note that if we were to show that two triangles are similar by SAS, we must show that no other pair of sides or angles are congruent between the two triangles. If there were another pair of congruent sides or angles, we would need to use a different similarity criterion such as angle-angle (AA) or side-side-side (SSS).

The sum of the interior angles of the polygon is 540° by the Sum of angles property of pentagon.

We know that the diagram is a plane figure with five sides, which means it is a Pentagon (Five-sided polygon), when from one vertex a line was drawn to the non-consecutive vertices, we need to find the sum of the interior angles of the polygon:

The total of interior angles in a polygon can be found by multiplying the quantity of triangles by 180°. It is noticeable that the number of triangles is consistently two less than the number of sides.

As a result, we can conclude that the formula for determining the sum of interior angles in a convex polygon with n sides is:

S = (n - 2) × 180°

This formula provides the sum of interior angles for any polygon.

Solution: A pentagon has five sides.

Therefore, by the angle sum formula we know that:

S = (n − 2) × 180°

Here we know that n = 5 as pentagon has 5 sides,

Hence, by the Sum of angles of pentagon = (5 − 2) × 180°

S = 3 × 180°

The lengths of the sides in ascending order are AB=1, BD=6, CD=7.

Length is a measurement of how long an object is in one dimension, usually referring to its distance from one end to the other. It is a fundamental physical quantity and is often measured in units such as meters, centimeters, feet, or inches, depending on the context and system of measurement being used. Length can be used to describe the size of physical objects, such as the length of a piece of wood or the distance between two points in space, as well as more abstract concepts, such as the length of time that has passed or the length of a written document.

According to the Triangle Inequality Theorem, the length of any side of a triangle must be less than the sum of the lengths of the other two sides.

If AB=1 and BD=6, then the third side must be less than AB+BD=1+6=7. Therefore, CD<7.

If AC=2 and BD=6, then the third side must be less than AC+BD=2+6=8. Therefore, CD<8.

If AD=3 and BD=6, then the third side must be less than AD+BD=3+6=9. Therefore, CD<9.

Since CD is less than all of these values, the possible length for CD is the smallest value, which is CD=7. Therefore, the segment for the third side of the triangle is CD.

The probability that a uniformly distributed random variable between 12 and 41 is between 22 and 35 is 41.7%.

Since the random variable is uniformly distributed between 12 and 41, the probability density function (PDF) of the random variable is constant within that interval and zero outside of it. Let X be the random variable between 12 and 41. Then,

f(x) = 1/(41-12) = 1/29, for 12 ≤ x ≤ 41

The probability that the random variable is between 22 and 35 can be found by integrating the PDF over the interval [22, 35]:

P(22 ≤ X ≤ 35) = ∫(22 to 35) f(x) dx = ∫(22 to 35) 1/29 dx

Using the definite integral, we get:

P(22 ≤ X ≤ 35) = [x/29] from 22 to 35

P(22 ≤ X ≤ 35) = (35/29 - 22/29) = 13/29

So, the probability that the random variable is between 22 and 35 is 13/29, which is approximately 0.4483 or 44.8% when expressed as a percentage rounded to one decimal place.

The probability that the proportion of airborne virus in the sample of 553 viruses is greater than 5% is 0.1151.

According to the central limit theorem, if a large sample of n > 30 is selected from an unknown population and the sample proportion of each sample is calculated, the sampling distribution of the sample proportion obeys the normal distribution.

The mean of the sampling distribution (U) for this sample proportion is:

U = p

The standard deviation (p) of the sampling distribution for this sample proportion is:

U = √ ((p(1 - p)) /n )

The sample size is, n = 553 > 30 so the central limit theorem applies in this case.

Up = √((p(1 - p))/n) = √((0.04 * 0.96)/553) = 0.0083

Calculate the probability that the proportion of virus in the air in 553 virus samples is greater than 3% as follows:

P(p >0.03)

= P (p - Up > (0.

= 0.11507

≈ ≈ 0.1151

Therefore, the probability that the proportion of airborne virus in a sample of 553 viruses is greater than 3% is 0.1151.

Answer:

sin A = cos B = a/h

A and B are complements of each other, so A + B = 90°. It follows that B = 90° - A, meaning sin A = cos(90° - A).
