Answer:

The answer is s = 1.

Step-by-step explanation:

Opposite sides of a parallelogram are equal so,

3s + 19 = s + 21

3s - s = 21 - 19

2s = 2

s = 1

next,

s + 21 =? 3s + 19

1 + 21 equal to (?) 3(1) + 19

22 = 22

so the answer is correct

Answer:

Answer:

80°

Step-by-step explanation:

AB and AC are chords.

Chords AB and AC are at a distance of 2 units from the center of the circle.

-> Chord AB = Chord AC

\(\implies m(\widehat {AB})=m(\widehat {AC})\)...(1)

(Equal chords intercept equal arcs)

\(m(\widehat {AB})+m(\widehat {AC})+m(\widehat {BC})=360\degree\)

(By arc sum property of a circle)

\(\implies m(\widehat {AB})+m(\widehat {AB})+200\degree=360\degree\)

(From equation 1)

\(\implies 2m(\widehat {AB})=360\degree-200\degree\)

\(\implies 2m(\widehat {AB})=160\degree\)

\(\implies m(\widehat {AB})=\frac{160\degree}{2}\)

\(\implies \huge{\orange{m(\widehat {AB})={80\degree}}}\)

The inequality that satisfies the number of hours of volunteer work that saul could complete each month to meet his goal is 21 hours.

An inequality in mathematics is a relation that compares two numbers or other mathematical expressions in an unequal way. The majority of the time, size comparisons between two numbers on the number line are made.

Different types of inequalities are represented by a variety of notations, including:

The symbol a <  b indicates that a is smaller than b.

When a > b is used, it indicates that an is bigger than b.

Given,

Hours Saul plans to volunteer in the 9-month period = 225 hours

Also,

Hours of volunteering he has already completed = 36 hours

=> Number of hours left = 225 - 36 =189 hours

Number of months= 9

=> Minimum number of hours he has to volunteer per month

=> \(\frac{Number of hours left}{Number of months}\)

=>\(\frac{189}{9}\\ 21 hours\)

=>Minimum number of hours saul has to volunteer per month ≥ 21 hours

Therefore, The number of hours of volunteer work that saul could complete each month to meet his goal is 21 hours.

Answer:

It earned $12,771 more in December.

Step-by-step explanation:

This question can be solved using a rule of three.

During an average month, we have that 100% = 1 is $47,300.

During December, the amount is $x, and it is 100% + 27% = 127% = 1.27. So

1 - $47,300

1.27 - $x

x = 1.27*47,300

x = 60,071

It earned $60,071 in December.

Compared to other months, it earned $60,071 - $47,300 = $12,771 more in December.

The probability that the student will be a student who lives on campus is 0.24

In math the term probability is referred as the branch of mathematics that studies the possible outcomes of given events together with the outcomes' relative likelihoods and distributions.

Here we have given that one full-time student who is a freshman or sophomore is selected at random.

Here we need to find the probability that the student will be a student who lives on campus.

Here we know that the probability that a student is a sophomore is calculated as,

=> P(S) = 19/42 = 0.45.

Whereas the probability that a student has a freshman is calculated as,

=>P(H)=25/42=0.6.

Then the probability that the student will be a student who lives on campus is calculated as,

=> P(H∩S)=P(S)+P(H)−P(S∪H)

Apply the values then simplify this one then we get,

=> 0.45+0.6−(42−8)/42=0.24

The ledge of the distance from which the pot fell was approximately 1.541 meters .

The equations of motion under constant acceleration that the pot falls vertically under the influence of gravity, so the acceleration is the acceleration due to gravity, which is approximately 9.8 m/s². Let's label the knowns and unknowns:

Knowns:

Time taken to pass from top to bottom (Δt) = 0.186 seconds

Distance travelled (Δy) = 1.60 meters

Acceleration due to gravity (g) = 9.8 m/s²

Unknown:

Distance above the top of the window to the ledge (h)

We can use the following kinematic equation to relate these variables:

Δy = v₀Δt + 0.5gt²

In this case, the initial velocity (v₀) is 0 since the pot was at rest when it fell.  simplify the equation to:

Δy = 0.5gt²

for h, the distance above the top of the window to the ledge:

h = Δy - 0.5gt²

Substituting the given values:

h = 1.60 m - 0.5 × 9.8 m/s² × (0.186 s)²

Calculating:

h ≈ 1.60 m - 0.5 × 9.8 m/s² ×0.034596 s²

h ≈ 1.60 m - 0.5 ×9.8 m/s² × 0.001196 s²

Rounding to 2 decimal places, the missing side of the right triangle is approximately 15.62 units.

To find the missing side of a right triangle, we can use the Pythagorean theorem, which states that in a right triangle, the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.

In this case, we are given sides a = 10 and b = 12, and we need to find the missing side c.

Using the Pythagorean theorem:

c^2 = a^2 + b^2

Substituting the given values:

c^2 = 10^2 + 12^2

c^2 = 100 + 144

c^2 = 244

Taking the square root of both sides to solve for c:

c = √244

c ≈ 15.62

The spherical correlation is a mathematical concept that satisfies a generalized Fourier theorem. This theorem enables us to compute the spherical correlation efficiently using a generalized (non-commutative) method.

To understand this, let's break it down step by step:

1. The spherical correlation is a measure of similarity between two spherical functions. It is commonly used in signal processing and image analysis.

2. The generalized Fourier theorem states that any function can be represented as a sum of spherical harmonics. Spherical harmonics are a set of functions defined on the surface of a sphere.

3. By applying the generalized Fourier theorem to the spherical correlation, we can express it as a sum of spherical harmonics. This allows us to efficiently compute the correlation using the properties of spherical harmonics.

4. The non-commutative nature of the generalized method means that the order of operations is important. In other words, the operations may not commute or switch places, affecting the final result.

In conclusion, the spherical correlation satisfies a generalized Fourier theorem, which provides an efficient way to compute it using a generalized (non-commutative) approach.

Answer:

The hand moved \(\bf \frac{3}{4}\) of a complete turn.

Step-by-step explanation:

The hand moved from 3 to 12, that is, it moved:

12 - 3 = 9 hours

In a clock, 12 hours represent a complete turn.

∴ Using the unitary method:

12 hours    ⇒     1 turn

1 hour        ⇒     \(\frac{1}{12}\) turns

9 hours     ⇒     \(\frac{1}{12}\)  × 9 = \(\frac{9}{12}\)

                                     = \(\bf \frac{3}{4}\) turns    (simplified)

∴ The hand moved \(\bf \frac{3}{4}\) of a complete turn.

The answer is  \(\boxed{\frac{3}{4}}\).

To find the fraction of a complete turn it moved in this case, take the ratio between hours covered between 3 and 12, and the hours covered in a complete turn.

There is no inherent relationship between the median and the average. It is possible for the median to be greater than the average or vice versa, depending on the specific values in the set.

To determine whether the median of the 5 numbers is greater than the average (arithmetic mean), we need the actual values of the numbers. Without specific values, we cannot provide a definitive answer. However, I can explain the concept of the median and the average to help you understand how they relate to each other.

The median is the middle value of a set of numbers when they are arranged in ascending or descending order. If there is an odd number of values, the median is the middle number. If there is an even number of values, the median is the average of the two middle numbers.

The average, or arithmetic mean, is calculated by summing up all the values in a set and dividing the sum by the number of values.

In general, there is no inherent relationship between the median and the average. It is possible for the median to be greater than the average or vice versa, depending on the specific values in the set.

The equation of circle D is (x + 2)2 + y² = 32 then the points (-6,-4) and (-4,6) lie on circle D

The equation of a circle with center (h,k) and radius r is (x - h)² + (y - k)² = r².

This is called the standard form of the equation of a circle.

In the given equation, (x + 2)² + y² = 32, we can see that the center of the circle is (-2, 0) and the radius is √32 = 4√2.

To determine which points lie on the circle, we substitute the x and y coordinates of each point into the equation and check if the equation is true.

If it is true, then the point lies on the circle.

Let us check if (-6, -4) lies on the circle, we substitute x = -6 and y = -4 into the equation:

(-6 + 2)² + (-4)² = 32

(-4)² + (-4)² = 32

16 + 16 = 32

32 = 32

An inequality that can be written in the form ax + by < c (where a and b are not both zero) is called a linear inequality in two variables.

An inequality that represents a line in a two-dimensional coordinate system is referred to as a linear inequality. The set of points that satisfies the inequality is a half-plane bounded by a line that may be dashed or solid.

In contrast to a linear equation, which represents a line, a linear inequality represents a half-plane. The points on one side of the line, rather than the points on the line, are solutions to the inequality.

The method of shading is used to graph a linear inequality in two variables. First, graph the boundary line, which is usually represented by a solid or dashed line, and then select a test point on one side of the line. Shaded regions of the half-plane containing the test point satisfy the inequality.

Abilities and altitudes are two individual differences that are generally reliable indicators of the likelihood of system error.

The ability of an individual to effectively use a system is a reliable indicator of the likelihood of system errors. People who are less experienced and less knowledgeable about the system are more likely to make mistakes, which can lead to system errors.

In addition, an individual's attitude towards the system can also have an effect. People who are more anxious or frustrated while using the system may make more errors due to a lack of concentration or incorrect assumptions.

Finally, an individual's susceptibility to stress can also play a role in how likely they are to make mistakes while using the system as stress can lead to a lack of focus and poor decision-making. Knowing these two human individual differences can help to predict the likelihood of system errors and help to reduce the risk of them occurring.
