The probability of selecting a piece of pottery is 7/26, and when converted to a percentage and rounded to the nearest whole percent, it is approximately 27%.

An archaeologist uncovers 26 artifacts from a site. The types of artifacts are shown below. The horizontal axis represents tools, pottery, and coins. The vertical axis represents the number of artifacts and ranges from 0 to 16, in increments of 2. The number of artifacts of tools is 14. The number of artifacts of pottery is 7. The number of artifacts of coins is 5.

The total number of artifacts at the site = 26

Number of pottery artifacts = 7

Probability of selecting a piece of pottery = Number of pottery artifacts/Total number of artifacts

Probability of selecting a piece of pottery = 7/26

If we want to express this probability in a percentage, we can convert it by multiplying it by 100.

Thus,Probability of selecting a piece of pottery = 7/26 = 0.269 = 26.9% (rounded to the nearest whole percent)

To address the ambiguity in communication, we can employ a method that involves reviewing various potential statements (both general and specific) that could be made.

Start by acknowledging the need to tackle ambiguity in communication.

Implement a method that involves a thorough review of possible statements that can be made. This review should encompass both general statements and specific statements.

General statements refer to broader and more abstract statements that could be potentially used in communication.

Specific statements, on the other hand, pertain to more precise and detailed statements that can be employed in communication.

The purpose of reviewing these possible statements is to anticipate different interpretations or misinterpretations that may arise due to ambiguous language.

By considering a range of potential statements, we can assess the clarity, precision, and potential for misunderstandings associated with each statement.

The goal is to select the most appropriate statement that effectively conveys the intended message while minimizing ambiguity.

It is important to note that the method outlined here is a proactive approach to addressing ambiguity in communication. By carefully considering and reviewing potential statements, we can enhance clarity and ensure effective communication.

Answer:

  236 in²

Step-by-step explanation:

You want the surface area of the figure comprised of two cuboids.

The surface area of the figure will be the sum of the total surface area of the purple cuboid, plus the lateral surface area of the yellow cuboid.

  SA = 2(LW +H(L +W)) + Ph

  SA = 2(9·4 +2(9 +4)) +(4·4)(7) = 236 . . . . square inches

The surface area of the composite figure is 236 square inches.

__

Additional comment

You can consider the face on the right side to be equal in area to the area of the purple cuboid that is covered by the yellow one. So, figuring the total area of the purple cuboid effectively includes the area of the face on the right side.

Then the remaining part of the area of the yellow cuboid is the area of the four 7×4 rectangles that are its lateral area.

The lifting force (f) is given by the formula, f = kav², where k is the constant of variation. It is given that the lifting force varies jointly as the area (a) of the wing's surface and the square of the plane's velocity (v).

f = kav² ----- (1)

The given values are:

a = 230 sq. ft.

v1 = 240 mph

f1 = 14100 lbs

v2 = 150 mph

We need to find the lifting force (f2) when the plane slows down to 150 miles per hour. Now, we need to find the value of the constant of variation (k). We have,

f1 = kav1²

14100 = ka (230) (240)²

14100 = ka (230) (57600)

14100 = 13248000a

k = 14100 / (13248000a) ----- (2)

We can substitute equation (2) into equation (1).We have,

f = 14100 / (13248000a) x a x v² ----- (3)

We can substitute the given values into equation (3).

We have,

f2 = 14100 / (13248000a) x a x 150²

f2 = 14100 / (13248000 x 230) x 150²

f2 = 563 / 5064 x 22500

f2 = 2493.24324324

The lifting force on the wing if the plane slows down to 150 miles per hour is 2493.24324324 pounds.

When a population mean is compared to the mean of all possible sample means of size 25, the two means are normally distributed.

A population is a collection of individuals or objects that we want to study in order to gain knowledge about a particular phenomenon or group of phenomena.

The sampling distribution of the sample means is the distribution of all possible means of samples of a fixed size drawn from a population.

It can be shown that, if the population is normally distributed, the sampling distribution of the sample means will also be normally distributed, regardless of sample size. The Central Limit Theorem is the name given to this principle.

To summarize, the two means are normally distributed when a population mean is compared to the mean of all possible sample means of size 25.

The probability that the mean annual precipitation of a sample of 49 randomly picked years will be less than 92.8 inches is, 0.9192

What is standard deviation?

The standard deviation in statistics is a measurement of how much a group of values can vary or be dispersed. A low standard deviation suggests that values are often close to the set's mean, whereas a large standard deviation suggests that values are dispersed over a wider range.

Given: The annual precipitation amounts in a certain mountain range are normally distributed with a mean of 90 inches, and a standard deviation of 14 inches.

z score is given by,

z = (x - μ)/(σ/√n) = (92.8 - 90)/(14/√49) = 2.8/2 = 1.4

The  required probability is,

p(z < 1.4) = 0.9192, by standard normal table.

Hence, the  probability that the mean annual precipitation of a sample of 49 randomly picked years will be less than 92.8 inches is,  0.9192.

A subset of a population selected to represent the population is a sample.

A sample is a subset of a population that is selected to represent the larger population as a whole. It is important to select a representative sample so that the results of the analysis are accurate and reliable.

A population can be defined as a group of individuals, objects, or subjects that share common observable characteristics or traits. A population is a group of things that share something in common, and it can be any size.

A sample is a smaller group of individuals, objects, or subjects that are taken from the population to perform research or statistical analysis. Samples are typically used in research to estimate what is happening in the population as a whole.

A subset is a subset of a larger group.

In other words, it is a smaller set that is part of a larger set. A subset can contain any number of elements or members, and it can be of any size.

Hence, the "a sample" is correct.

The probability that the second light is green, given that the first light is green, is 0.695 or approximately 69.5%.

We can use Bayes' Theorem to find the probability that the second light is green, given that the first light is green. Let G1 and G2 denote the events that the first and second lights are green, respectively. Then we have:

P(G2 | G1) = P(G1 and G2) / P(G1)

We are given that P(G1 and G2) = 0.41, and P(G1) = 0.59. Substituting these values, we get:

P(G2 | G1) = 0.41 / 0.59 = 0.695

Therefore, the probability that the second light is green, given that the first light is green, is 0.695 or approximately 69.5%.

To answer your question, we will use the conditional probability formula:

P(A and B) = P(A) * P(B|A)

In this case, A represents the first light being green, B represents the second light being green, and P(A and B) is the probability of both lights being green. We are given the following:

P(A and B) = 0.41
P(A) = 0.59
We need to find P(B|A), which is the probability that the second light is green given that the first light is green.

Using the formula, we have:

0.41 = 0.59 * P(B|A)

To solve for P(B|A), divide both sides by 0.59:

P(B|A) = 0.41 / 0.59 ≈ 0.6949

Therefore, the probability that the second light is green, given that the first light is green, is approximately 0.6949.

Step-by-step explanation:

Circle O is represented by the equation (x+7)² + (y + 7)² = 16. The length of the radius of Circle O is 4.

The equation of Circle O, (x+7)² + (y+7)² = 16, is in the standard form of a circle equation: (x - h)² + (y - k)² = r². Comparing it to the given equation, we can determine the values of h, k, and r.

In the given equation:

Center coordinates: (-7, -7) → h = -7, k = -7

Radius squared: 16 → r² = 16

To find the length of the radius, we need to take the square root of r²:

r = √(16)

Calculating the square root, we get:

r = 4

Therefore, the length of the radius of Circle O is 4.

Looking at the answer options, we see that the correct answer is Option B which is equal to 4.

The equation of a circle in the standard form (x - h)² + (y - k)² = r² represents a circle with center (h, k) and radius r. By comparing the given equation to the standard form, we can extract the values of h, k, and r. Taking the square root of r² gives us the length of the radius, which in this case is 4.

The speed of the object is 12121 m per week.

What does it mean to do speed?

The object is moving at a speed of 2 centimeters every 7 seconds.

We need to find the speed in m per week.

2 cm = 0.02 m

1 week = 604800 s

7 s =  \(1.65 * 10^{-6} week\)

Speed = distance/time

So,

\(v = \frac{0.02 m}{1.65 * 10^{-6 } week}\)

\(v = 12121.21 m/ week\)

or v = 12121 m/ week

So, the speed of the object is 12121 m per week.
