the equation to represent the number of hours, t, the bird will take to fly d kilometers at this rate is t = 2d / 71.2

We can use the formula for distance, rate, and time:

distance = rate x time

We can rearrange this formula to solve for time:

time = distance / rate

If we substitute the given distance of 71.2 km and rate of (71.2 km / 2 hours) into this formula, we can find the time it took the bird to fly 71.2 km:

time = 71.2 km / (71.2 km / 2 hours) = 2 hours

Now, we can use the same formula to find the time it will take the bird to fly d kilometers:

time = d km / (71.2 km / 2 hours) = 2d / 71.2 hours

Therefore, the equation to represent the number of hours, t, the bird will take to fly d kilometers at this rate is t = 2d / 71.2

Answer:

The formula is: x = -y + z

We are given that y = 3 and z = 1. Substituting these values in the formula, we get:

x = -y + z

x = -(3) + 1

x = -3 + 1

x = -2

Therefore, when y = 3 and z = 1, the value of x is -2.

Step-by-step explanation:

The given formula is: x = -y + z

We are given that y = 3 and z = 1.

Substitute the values of y and z into the formula.

x = -y + z

x = -(3) + 1

x = -3 + 1

Simplify the expression.

x = -2

Therefore, when y = 3 and z = 1, the value of x is -2.

No, a binomial experiment cannot be used to determine the probability that the rods are the correct length or an incorrect length.

A binomial experiment has the following characteristics:

1. It consists of a fixed number of trials.

2. Each trial has only two possible outcomes: success or failure.

3. The trials are independent.

4. The probability of success is constant for each trial.

In the case of metal rods, the length can vary continuously, so it is not a binary outcome. Therefore, a binomial experiment cannot be used to determine the probability of the rods being the correct length or an incorrect length. Instead, a probability distribution such as a normal distribution could be used to model the distribution of rod lengths and calculate the probability of a rod being the correct length.

The cube root function that tells the side lengths of the​ container, x, in inches for a given​ cost, C is x = (C^(1/3))^3.

We can use the formula for the volume of a cube, which is V = x^3, where x is the side length of the cube. If the cost of producing one cube-shaped container is C dollars, then the cost of producing one unit of volume is C/V = C/x^3 dollars per cubic inch. Solving for x, we get:

x = (C/V)^(1/3)

Substituting V = x^3, we get:

x = (C/x^3)^(1/3)

Simplifying, we get:

x = (C^(1/3)) / (x^(1/3))

Multiplying both sides by x^(1/3), we get:

x^(2/3) = C^(1/3)

Taking the cube of both sides, we finally get:

x = (C^(1/3))^3

Therefore, the cube root function for a given cost, C, is x = (C^(1/3))^3.

Increase in the level of confidence and increase in the population standard deviation will increase the width of a confidence interval and increasing the sample size will decrease the width of a confidence interval.

(a) Increasing the level of confidence will increase the width of a confidence interval. This is because a higher level of confidence requires a larger margin of error, which in turn increases the width of the interval.

(b) Increasing the sample size will decrease the width of a confidence interval. This is because a larger sample size leads to a more precise estimate of the population parameter, which reduces the amount of uncertainty and therefore narrows the interval.

(c) Increasing the population standard deviation will increase the width of a confidence interval. This is because a larger standard deviation indicates greater variability in the population, which in turn requires a larger margin of error and therefore widens the interval.

Answer: Let's draw a diagram to visualize the situation:

                   C (water tower)

                  /|

                 / |  25°

         12000 /  |

               /   |

              /    |

             /     |

            /θ     | B (plane)

           A       |

In this diagram, the pilot of the airplane is located at point B and the water tower is located at point C. The angle of depression from the airplane to the base of the tower is 25°. We are asked to find the length of the line of sight from the airplane to the tower, which is the distance AC.

We can use trigonometry to solve for AC. In particular, we can use the tangent function, which relates the opposite side to the adjacent side of a right triangle:

tan(θ) = opposite / adjacent

In this case, the opposite side is BC (the height of the water tower) and the adjacent side is AB (the distance from the airplane to the base of the tower). We can rearrange the equation to solve for AB:

AB = BC / tan(θ)

We know that BC is the height of the water tower, but we don't have that information. However, we can use the fact that the angle of depression is 25° to find BC. The angle of depression is the angle between the horizontal line (which we can assume is the same as the ground level) and the line of sight from the airplane to the base of the tower. Therefore, the angle between the line of sight and the vertical line (which is perpendicular to the ground) is 90° - 25° = 65°. This means that the triangle ABC is a right triangle, with angle θ = 65°.

Now we can use trigonometry again to find BC, using the sine function:

sin(θ) = opposite / hypotenuse

In this case, the opposite side is BC (the height of the water tower) and the hypotenuse is AC (the line of sight from the airplane to the tower). We can rearrange the equation to solve for BC:

BC = sin(θ) x AC

We know that θ = 65° and sin(θ) ≈ 0.9063 (you can use a calculator to find this value). Substituting these values into the equation gives us:

BC = 0.9063 x AC

Now we can substitute this expression for BC into the equation we derived earlier:

AB = BC / tan(θ) = (0.9063 x AC) / tan(65°)

We can simplify this expression by noting that tan(65°) ≈ 2.1445 (you can use a calculator to find this value). Substituting this value gives us:

AB = (0.9063 x AC) / 2.1445

Multiplying both sides by 2.1445 gives us:

2.1445 x AB = 0.9063 x AC

Dividing both sides by 0.9063 gives us:

AC = (2.1445 x AB) / 0.9063

We know that AB is the altitude of the airplane, which is given as 12,000 feet. Substituting this value gives us:

AC = (2.1445 x 12,000) / 0.9063 ≈ 28,406 feet

Therefore, the length of the line of sight from the airplane to the water tower is approximately 28,406 feet.

m∠RSQ = 13°

TQ = SR = 3x

Quadrilateral which is made up of 2 pairs of parallel sides. The opposite sides are parallel and equal in length in a parallelogram.

Since QRST is a parallelogram, opposite angles are congruent. Therefore, we have:

m∠R = m∠T = 180° - m∠QTS = 180° - 66° = 114°

Also, since QRST is a parallelogram, opposite sides are congruent. Therefore, we have:

SR = TQ = 3x

Finally, we can use the fact that the sum of the angles in a triangle is 180° to find m∠RSQ:

m∠RSQ = 180° - m∠QST - m∠T = 180° - 53° - 114° = 13°

The frequency with largest amplitude  for the particular solution to the differential equation is w = 0.707 (approximately).

To find the frequency with the largest amplitude, we can assume that the particular solution to the given differential equation is of the form:

y(t) = Aeiwt

Taking the first and second derivatives of y(t), we get:

dy/dt = iwtAeiwt

d2y/dt2 = -w2Aeiwt

Substituting these into the differential equation, we get:

-w2Aeiwt + 2Aeiwt = eiwt

Simplifying, we get:

A = 1 / (1 - 2iw2)

The amplitude of y(t) is given by |A|, which is:

|A| = 1 / |1 - 2iw2|

To find the frequency w for which |A| is largest, we need to minimize the modulus of the denominator of A over all frequencies w. We can do this using numerical optimization methods. So, frequency is 0.707.

Depending on the correlations between the days, the answer can be anywhere from 25% (perfect correlation) to 100% (for example, first four days mutually exclusive).

If you assume the days are independent, which may be what you intended to ask but is not actually a good assumption when it comes to the weather, then the probability is 1 - (1-0.25)^5 = 76%

The issue pertains to probability theory, and specifically the calculation of the likelihood of precipitation on a particular day. We need to find the total probability that it rains at least three out of five days, and this would require enumerating and counting all possible outcomes.

This is a problem of probability related to weather forecasts, specifically concerned with the chance of rain. The first day has an independent probability of 1/2 (rain or no rain). Thereafter each day's weather depends on the previous day's. If it rained the day before, there's a 2/3 chance it will rain the next day, and 1/3 chance it won't. If it didn't rain, those chances are reversed.

To get the probability that it rains at least three out of five days, we will think about it in terms of the total possible outcomes and the desired outcomes. The problem can be solved by counting the number of ways that we can have 3, 4 or 5 rainy days out of 5 and then multiplying each by the probability of that particular event.

By following these steps, we will arrive at the total probability, which might require a sophisticated understanding of probability theory.

Squareroot of 100 is 10

The size of the angle PRQ is 300 degrees.

What is congruent?

The term “congruent” means exactly equal shape and size. This shape and size should remain equal, even when we flip, turn, or rotate the shapes.

In a regular 12-sided polygon, each interior angle has a measure of:

(12 - 2) × 180° / 12 = 150°

Since PR is diagonal, it divides the 12-sided polygon into two congruent triangles. Therefore, the angle PQR is half of the angle PRQ.

Let x be the measure of angle PRQ. Then we have:

x + 150° + 150° = 180° (sum of angles in triangle PQR)

Simplifying the equation, we get:

x = 180° - 150° - 150° = -120°

However, since x is an angle in a triangle, it must be positive. Therefore, we take the supplement of x, which is:

180° - x = 180° - (-120°) = 300°

Hence, the size of the angle PRQ is 300 degrees.

Answer:

Step-by-step explanation:

The perimeter of a quarter circle can be calculated by adding the length of the arc and the two radii that make up the quarter circle.

The length of the arc of a quarter circle is given by (πr)/2, where r is the radius of the quarter circle and π is approximately 3.142 (as given in the question).

So, for a quarter circle with a radius of 7 cm, the length of the arc would be:

(πr)/2 = (3.142 x 7)/2 = 10.997 cm (rounded to 3 decimal places)

The two radii that make up the quarter circle are each equal to the radius of the quarter circle, so the total length of the two radii would be:

2r = 2 x 7 = 14 cm

Therefore, the perimeter of the quarter circle would be:

10.997 cm + 14 cm = 24.997 cm (rounded to 3 decimal places)

So the perimeter of the quarter circle is approximately 24.997 cm. The digits given by the calculator will depend on the specific calculator used.
