Step-by-step explanation:

You want to know the distance to a source of sound if it is heard through a medium with a speed of sound of 5030 m/s 6 seconds before it is heard through a medium with a speed of sound of 335 m/s.

The relation between time, speed, and distance is ...

  time = distance/speed

For some distance d in meters, the two times are d/335 seconds and d/5030 seconds. The time difference is 6 seconds, so we have ...

  d/335 -d/5030 = 6

Multiplying by 337010, we have ...

  1006d -67d = 2022060

  939d = 2022060 . . . . . simplify

  d ≈ 2153.42 . . . . . meters

The source of sound is about 2153 meters away.

Additional comment

The distance might rightly be rounded to 2150 meters, since the given numbers are 3 significant figures each.

Since the percentage of individuals owning an Xbone was not provided, we can find the percentage by subtracting the percentages of those who own a PS4 and a Switch from 100%:

Percentage of Xbone owners = 100% - 65% - 20% = 15%

The probability that all three individuals own an Xbone is:

P(Xbone) = 0.15

P(all three own an Xbone) = P(Xbone) x P(Xbone) x P(Xbone) = 0.15 x 0.15 x 0.15 = 0.003375 or approximately 0.34%

Therefore, the probability that all three individuals own an Xbone is approximately 0.34%.

The probability that at least one individual owns an Xbone is the complement of the probability that none of the individuals own an Xbone:

P(at least one Xbone) = 1 - P(no Xbone)

To find the probability that none of the individuals own an Xbone, we can use the percentage of Xbone owners that we calculated in part (5):

P(no Xbone) = 1 - P(Xbone) = 1 - 0.15 = 0.85

P(at least one Xbone) = 1 - P(no Xbone) = 1 - 0.85 = 0.15

Therefore, the probability that at least one individual owns an Xbone is 0.15 or 15%.

Answer:

Cost per pound = $8.72

Step-by-step explanation:

Since Mrs. Thomas spent $26.16 for 3 pounds' worth of turkey, all you need to do is divide $26.16 by 3 to get the cost per pound.

$26.16 ÷ 3 pounds = $8.72 per pound of turkey

The y-value for the point that divides the line segment XY into a ratio of 1:2 is-0.33. Thus, the option A is correct.

As per the question, the coordinates of point X are (-6, -1) and the coordinates of point Y are (5, 1).

We have to find the y-value for the point that divides the line segment XY into a ratio of 1:2.

Using the section formula, we substitute the values into the formula:

x = (1 * 5 + 2 * (-6)) / (1 + 2)

y = (1 * 1 + 2 * (-1)) / (1 + 2)

Simplifying the equations:

x = (5 - 12) / 3

= -7 / 3

y = (1 - 2) / 3

= -1 / 3

= -0.33

Therefore, the y-value for the point that divides the line segment XY into a ratio of 1:2 is-0.33.

Answer:

Step-by-step explanation:

Therefore, the value of F is approximately 18.92 degrees.

An angle is a geometric figure formed by two rays that share a common endpoint, called the vertex of the angle. The rays are also known as the sides or legs of the angle. Angles are typically measured in degrees or radians and can be classified based on their measure as acute (less than 90 degrees), right (exactly 90 degrees), obtuse (between 90 and 180 degrees), or straight (exactly 180 degrees). Angles are an important concept in geometry and have many real-world applications, including in physics, engineering, and architecture.

Here,

If we look at the diagram, we can see that angles d° and e° are vertical angles, which means they are equal in measure. Similarly, angles (9-86)° and 45° are supplementary angles, which means they add up to 180°. Using this information, we can set up an equation:

d = e (since they are vertical angles)

(9-86) + 45 + e + (6f) + 15 = 180 (since the sum of angles in a triangle is 180°)

Simplifying the equation, we get:

-32 + e + 6f + 60 = 180

e + 6f + 28 = 180

e + 6f = 152

Substituting d = e, we get:

d + 6f = 152

But we know that d + e + (9-86) = 180 (since the sum of angles in a straight line is 180°)

Substituting d = e, we get:

2d + (9-86) = 180

2d = 77

d = 38.5

Substituting d = e = 38.5 in the equation e + 6f = 152, we get:

38.5 + 6f = 152

6f = 113.5

f = 18.92

Explanation:

To calculate the circumference of a circle, multiply the diameter of the circle with π (pi). The circumference can also be calculated by multiplying 2×radius with pi (π=3.14)

We have shown that p(k+1) = p, assuming that pk = p. Hence, by mathematical induction, pk = p for k = 1, 2, ….

(a) Show that p² = p

We are given that p = a(ata)-1at, where a is an m × n matrix of rank n.

To prove that p² = p, we need to show that p.p = p.

To do this, we can first multiply p with (ata):

p.(ata) = a(ata)-1at.(ata)

Using the associative property of matrix multiplication, we can write this as:p.(ata) = a(ata)-1(a(ata))(ata)

= a(ata)-1a(ata)

Since a has rank n, a(ata) is an n × n matrix of full rank.

Therefore, its inverse (a(ata))-1 exists.

Using this, we can simplify our expression for p.(ata) as follows:

p.(ata) = I, the n × n identity matrix

Therefore, we have shown that: p.(ata) = I.

Substituting this into our expression for p²:

p² = a(ata)-1at.a(ata)-1at

= p.(ata)p

= p,

since we just showed that p.(ata) = I.

(b) Prove that pk = p for k = 1, 2, …

We can prove that pk = p for k = 1, 2, … using mathematical induction.

For the base case, k = 1:pk = p¹ = p, since anything raised to the power of 1 is itself.

For the inductive step, we assume that pk = p for some arbitrary value of k and then try to prove that p(k+1) = p.

For k ≥ 1, we have:p(k+1) = pk.p, by the definition of matrix multiplication= p.p, using the assumption that pk = p= p, using part (a) of this question.

Therefore, we have shown that p(k+1) = p, assuming that pk = p. Hence, by mathematical induction, pk = p for k = 1, 2,

Mathematical induction is a technique used to prove that a statement is true for all values of a variable. It is based on two steps: the base case and the inductive step.In the base case, we show that the statement is true for a specific value of the variable.

In the inductive step, we assume that the statement is true for some arbitrary value of the variable and then try to prove that it is also true for the next value of the variable. If we can do this, then the statement is true for all values of the variable.In this question, we are asked to prove that pk = p for k = 1, 2, ….

We can use mathematical induction to do this.For the base case, k = 1, we have:p¹ = p, since anything raised to the power of 1 is itself.Therefore, the statement is true for the base case.

Now, we assume that the statement is true for some arbitrary value of k, i.e., pk = p, and try to prove that it is also true for k + 1.

For k ≥ 1, we have:

p(k+1) = pk.p, by the definition of matrix multiplication= p.p, using the assumption that pk = p= p, using part (a) of this question

Bar charts display categorical variables, whereas histograms display numerical or quantitative data.

The frequency distribution of a few data points for one variable is represented graphically by a histogram. Heterogeneous "bins" or "range groups" are frequently used in histograms in order to categorize data and count the number of data points that are part of each bin.

Among graphing tools, the histogram is widely used. It is utilized to encapsulate discrete or continuous data that is measured on an interval scale. It is frequently employed as a convenient way to highlight the key characteristics of the data distribution.

Histograms show numerical or quantitative data, whereas bar charts show categorical factors. The numerical data in a histogram will typically be continuous in most cases (having infinite values). It would be ridiculous to attempt to plot an axis that included every potential value for a continuous variable.
