Answer:

\(|{\sf XY}| = 10\; {\rm cm}\).

Step-by-step explanation:

Refer to the diagram attached. The dashed segment attached to \(\!{\sf Z}\) points to the north. Rotating this segment clockwise with point \({\sf Z}\!\!\) as the fixed center of rotation would eventually align this segment with the one between point \(\!\!{\sf Z}\) and point \(\!\!{\sf X}\). The bearing of point \({\sf X}\) from point \({\sf Z}\) is the size of the angle between these two line segments when measured in the clockwise direction.

Subtract the bearing of \({\sf Y}\) from \({\sf Z}\) from the bearing of \({\sf X}\) from \({\sf Z}\) to find the measure of the angle \(\angle {\sf YZX}\):

\(\begin{aligned}\angle {\sf YZX} &= 135^{\circ} - 45^{\circ} \\ &= 90^{\circ}\end{aligned}\).

Thus, triangle \(\triangle {\sf YZX}\) is a right triangle (\(90^{\circ}\)) with segment \({\sf YX}\) as the hypotenuse. It is given that \(|{\sf XZ}| = 6\; {\rm cm}\) whereas \(|{\sf ZY}| = 6\; {\rm cm}\). Thus, by Pythagorean's Theorem:

\(\begin{aligned}|{\sf ZY}| &= \sqrt{|{\sf ZX}|^{2} + |{\sf ZY}|^{2}} \\ &= \sqrt{(8\; {\rm cm})^{2} + (6\; {\rm cm})^{2}} \\ &= 10\; {\rm cm}\end{aligned}\).

Krista put 0.40 in the first equation meant for the number of stamps. Therefore, option A is the correct answer.

A system of linear equations consists of two or more equations made up of two or more variables such that all equations in the system are considered simultaneously. The solution to a system of linear equations in two variables is any ordered pair that satisfies each equation independently.

Given that, Krista was assigned a homework problem that stated there were 45 stamps purchased for $18.75. Some stamps were 40 cents, and some stamps were 55 cents.

Let 40 cents stamps be x and 55 cents stamps be y.

Now, x+y=45 --------------(I)

0.40x+0.55y=18.75 --------------(II)

System of equations Krista written are

0.40x+y=45 and x+0.55y=18.75

Therefore, option A is the correct answer.

The confidence interval is not focused on containing the value of 3.

based on the given information, we can determine that the null hypothesis, h0, is rejected, which means there is evidence to support the alternative hypothesis h > 35 cm.

given this, we can conclude that the true mean petal length is likely to be greater than 35 cm.

now, let's consider the statements about the confidence interval:

a. a 90% confidence interval contains the hypothesized value of 3.5.   this statement is not true because the hypothesis being tested is h > 35 cm, not h = 3.5 cm. 5 cm.

b. the hypothesized value of 3.5 is in the center of a 90% confidence interval.

  this statement is not true since the confidence interval is not centered around the hypothesized value of 3.5 cm. the focus is on determining if the true mean petal length is greater than 35 cm.

c. a 90% confidence interval does not contain the hypothesized value of 35.   this statement is not provided in the options, so it is not directly applicable.

Answer:

\(a_{n}\) = 4n + 3

Step-by-step explanation:

There is a common difference between consecutive terms, that is

11 - 7 = 15 - 11 = 19 - 15 = 4

This indicates the sequence is arithmetic with nth term

\(a_{n}\) = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 7 and d = 4 , then

\(a_{n}\) = 7 + 4(n - 1) = 7 + 4n - 4 = 4n + 3

The canonical expression equivalent to sinusoidal model y(t) = 2 · sin (4π · t) + 5 · cos (4π · t) is y(t) = (√ 29) · sin (4π · t + 0.379π) .

Herein we have a simple harmonic motion model represented by a sinusoidal expression of the form y(t) = A · sin (C · t) + B · cos (C · t), which must be transformed into its canonical form, that is, y(t) = A' · sin (C · t + D). We proceed to perform the procedure by algebraic and trigonometric handling.

The amplitude of the canonical function is determined by the Pythagorean theorem:

A' = √(2² + 5²)

A' = √ 29

The angular frequency C  is the constant within the trigonometric functions from the non-canonical formula:

C = 4π

Then, we find the initial position of the weight in time: (t = 0)

y(0) = 2 · sin (4π · 0) + 5 · cos (4π · 0)

y(0) = 5

And now we calculate the angular phase below: (A' = √ 29, C = 4π, y = 5)

5 = √ 29 · sin (4π · 0 + D)

5 / √ 29 = sin D

D ≈ 0.379π rad

The canonical expression equivalent to sinusoidal model y(t) = 2 · sin (4π · t) + 5 · cos (4π · t) is y(t) = (√ 29) · sin (4π · t + 0.379π) .

Answer:

70 dollars

1600 dollars

Step-by-step explanation:

The equation is

\(y=70x+1600\)

where

y = Total pay

x = Number of of copies of History is Fun sold

Cost of History is Fun is 70

Rita's fixed pay is 1600

The change in Rita's total pay for each copy of History is Fun sold she earns 70 dollars.

If she sells zero copies of History is Fun then x = 0

\(y=70\times 0+1600\\\Rightarrow y=1600\)

So, her total pay would be 1600 dollars.

The correct option is D, Per the Central Limit Theorem the mean of the sampling distribution of the sample mean is equal to the population Mean.

The Central Limit Theorem (CLT) is a fundamental concept in probability theory and statistics. It states that if you take repeated random samples of a population, the sample means will follow a normal distribution, regardless of the shape of the population distribution, provided the sample size is large enough. This means that as the sample size increases, the sample mean becomes more and more normally distributed.

The CLT is important because it helps us to understand the properties of large samples, even when the population is not normally distributed. It is used in many areas of research, including social sciences, finance, engineering, and more. The theorem provides a powerful tool for estimating population parameters, such as the mean or variance, and for testing hypotheses about them. It also helps to explain why the normal distribution is so commonly observed in real-world data, and why it is often used as a model for statistical analysis.

Answer:

it will take them 33 minutes and 20 seconds

Step-by-step explanation:

What we have here is that Han can stuff 20 envelopes in a minute while Clare can do 10 in a minute

So in a minute, they can jointly stuff 30 envelopes.

Mathematically we know that the number of time it will take to finish stuffing would be number of envelopes/ joint rate = 1000/30 envelopes per minute

So it will take 33 1/3 minutes

1/3 of a minute is same as 1/3 * 60 seconds = 20 seconds

So it will take them 33 minutes and 20 seconds

Answer:

210 in.

Step-by-step explanation:

Volume of a box = V = length x width x height

You don't have to know which number is the length, width and height since you are multiplying all of them together anyways.

V = 7in x 10in x 3in

V = 210 in

The volume of the box 210 cubic inches.

The volume of a cuboid is defined as the total number of cubic units occupied by the cuboid completely. A cuboid is a three-dimensional solid figure, having 6 square faces. Volume is nothing but the total space occupied by an object.

The dimensions of given box is length=7 inches, width=10 inches and height=3 inches.

We know that, volume of cuboid is length×width×height

Now, volume =7×10×3

= 210 cubic inches

To determine the exact values of sine, cosine, and tangent of an angle using the half angle formulas, we need the specific angle for which we want to calculate these values.

The half angle formulas allow us to find the values of trigonometric functions for an angle that is half the measure of a known angle. These formulas are derived from the double angle formulas and can be used to find exact values.

Identify the specific angle

To apply the half angle formulas, we need to know the measure or ratio of the specific angle for which we want to calculate the trigonometric values. Without this information, we cannot provide the exact values using the half angle formulas.

Apply the half angle formulas

Once we have the specific angle, we can use the appropriate half angle formula for the trigonometric function we want to calculate. The half angle formulas for sine, cosine, and tangent are as follows:

sine (θ/2) = ±√[(1 - cos θ) / 2]

cosine (θ/2) = ±√[(1 + cos θ) / 2]

tangent (θ/2) = ±√[(1 - cos θ) / (1 + cos θ)]

By substituting the known values or ratios of the angle into these formulas, we can determine the exact values of sine, cosine, and tangent for the given angle.

Calculate the exact values

Using the specific angle, we apply the appropriate half angle formula and perform the necessary calculations to obtain the exact values of sine, cosine, and tangent.
