What is the volume of a cylinder that is 15-m tall and has a radius of 3 m. Use 3.14 for π, and round your answer to the nearest cubic meter.

A. 141 m3
B. 283 m3
C. 339 m3
D. 424 m3

Answers

Answer:

D. 424 m³

Step-by-step explanation:

Use the formula for the volume of a cylinder

V = \(\pi\)r²h

Plug in the values we know

V = (3.14)(3²)(15)

V = 423.9 m³

This is closest to answer choice D, 424 m³

So, D is correct

Data are weight changes of humans, tabulated after administration of a drug proposed to result in weight loss Each weight change (in kg) is the weight after minus the weight before drug administration. A random sample of 12 subjects was selected to participate in this research. Which formulas should be used if the researcher wishes to make confidence intervals and do hypothesis testing? i. Type of problem: ii. What other information would you need to know to check the assumptions you need for this test?

Answers

The researcher can use certain formulas for finding confidence intervals and hypothesis testing in this scenario.

For confidence intervals, the formula for the mean difference would be used, which is the average of the weight changes in the sample.

This formula calculates the range within which the true population mean difference is likely to fall.

To conduct hypothesis testing, the researcher can use the formula for the t-test for a single sample.

This test compares the mean difference observed in the sample to a hypothesized value and determines whether there is enough evidence to support or reject the hypothesis.

To check the assumptions necessary for this test, the researcher would need additional information. The assumptions typically include:

1. Random sampling: It is important to ensure that the subjects were randomly selected from the population to generalize the results.

2. Normality: The weight changes should follow a normal distribution within the population.

The researcher would need to assess the normality assumption, such as by examining the distribution of weight changes or using statistical tests like the Shapiro-Wilk test.

3. Independence: The weight changes of one subject should not be influenced by the weight changes of another subject.

This assumption can be violated if the subjects are related or if there are repeated measurements on the same subjects.

By checking these assumptions and using the appropriate formulas, the researcher can make confidence intervals and perform hypothesis testing to draw conclusions about the effects of the drug on weight loss in the population.

Answers

Answer:

819,200

Step-by-step explanation:

First start by raising all the numbers to the power indicated:

5^4 = 625

8^5 = 32768

2^9 = 512

5^2 = 25

Then divide the numerators by the denominators:

625 / 8 = 78.125

32768 / 64 = 512

512 / 25 = 20.48

Finally, multiply all the numbers together

78.125 * 512 * 20.48 = 819200

Hanna says you cannot represent the fraction 1/4 on the number line.

Answers

Answer:

The answer is D; Hanna is not correct,. The fraction 1/4 is equal to 2/8, so you can graph it on the second tick mark to the right of zero.

Step-by-step explanation:

Because the number line is broken up into 8 parts, the points on the graph are, 1/8, 2/8, 3/8, 4/8, 5/8, 6/8, 7/8, 8/8 (also known as one)

1/4 = 2/8. We know this because if we multiply 1/4 by 2, we get 2/8.

So, because 2/8 is the same as 1/4, we know that Hanna is not correct, and that you can graph 1/4 on this number line, because it is the same as 2/8.

in a certain town, 40% of the people have brown hair, 25% have brown eyes, and 15% have both brown hair and brown eyes. a person is randomly selected from the town. using a venn diagram: a. if the randomly selected person has brown hair, then what is the probability that they also have brown eyes? b. if the person has brown eyes, what is the probability the they do not have brown hair? c. what is the probability that the person has neither brown eyes not brown hair?

Answers

For (a)  the probability that a person with brown hair also has brown eyes is 37.5%.

Let's calculate the probabilities directly:

Given:

P(Brown Hair) = 40% = 0.4

P(Brown Eyes) = 25% = 0.25

P(Brown Hair and Brown Eyes) = 15% = 0.15

a. Probability that a person with brown hair also has brown eyes:

We want to find P(Brown Eyes | Brown Hair), the probability that a person has brown eyes given that they have brown hair.

Using the formula for conditional probability:

P(Brown Eyes | Brown Hair) = P(Brown Hair and Brown Eyes) / P(Brown Hair)

P(Brown Eyes | Brown Hair) = 0.15 / 0.4 = 0.375 = 37.5%

Therefore, the probability that a person with brown hair also has brown eyes is 37.5%.

b. Probability that a person with brown eyes does not have brown hair:

We want to find P(Not Brown Hair | Brown Eyes), the probability that a person does not have brown hair given that they have brown eyes.

Using the formula for conditional probability:

P(Not Brown Hair | Brown Eyes) = P(Brown Eyes and Not Brown Hair) / P(Brown Eyes)

P(Not Brown Hair | Brown Eyes) = (P(Brown Eyes) - P(Brown Hair and Brown Eyes)) / P(Brown Eyes)

P(Not Brown Hair | Brown Eyes) = (0.25 - 0.15) / 0.25 = 0.10 = 10%

Therefore, the probability that a person with brown eyes does not have brown hair is 10%.

c. Probability that the person has neither brown eyes nor brown hair:

We want to find the probability that a person has neither brown eyes nor brown hair.

P(Neither) = 1 - P(Brown Hair) - P(Brown Eyes) + P(Brown Hair and Brown Eyes)

P(Neither) = 1 - 0.4 - 0.25 + 0.15 = 0.5 = 50%

Therefore, the probability that the person has neither brown eyes nor brown hair is 50%.

b. If x2 - 3x = 40, then x = 8.

d. If x(x - 3) = 40, then x2 - 3x = 40

Answers

The statement in if-then form is option a. If x = 8, then x2 - 3x = 40.

What are Expressions?

Expressions are statements consisting of two or more terms and terms are connected to each other using mathematical operators like addition, multiplication, subtraction and so on.

The given statement is,

For x = 8, x² - 3x = 40.

We have to rearrange this in if - then form.

If we have the quadratic equation,

x² - 3x = 40

x² - 3x - 40 = 0

(x - 8) (x + 5) = 0

So x = 8 or x = -5

So we cannot say that if x² - 3x = 40, x = 8, because there is a chance for -5 also.

If x = 8, then x² - 3x = (8)² - (3 × 8) = 40

Hence the correct option is a. If x = 8, then x2 - 3x = 40

The solution to the division of the given surd is: \(\mathbf{P =\dfrac{(6\sqrt{x}-x^2\sqrt{x}-3x\sqrt{x}+2x+2)(x-1) }{8x} }\)

Division of Surds.

The division of surds follows a systemic approach whereby we divide the whole numbers separately and the root(s) are being divided by each other.

Given that:

\(\mathbf{P=(\frac{\sqrt{x} +2}{x-1}+\frac{\sqrt{x}\\ -2}{x-2\sqrt{x} +1} ) : \frac{4x}{(x-1)^{2} }}\)

i.e.

\(\mathbf{=\dfrac{(\frac{\sqrt{x} +2}{x-1}+\frac{\sqrt{x}\\ -2}{x-2\sqrt{x} +1} )}{ \frac{4x}{(x-1)^{2} }} }\)

Using the fraction rule:

\(\mathbf{\dfrac{a}{\dfrac{b}{c}}= \dfrac{a\times c}{b}}\)

\(\mathbf{\implies \dfrac{(\frac{\sqrt{x} +2}{x-1}+\frac{\sqrt{x}\\ -2}{x-2\sqrt{x} +1} )(x-1)^{2}}{4x}} }\)

By simplification, we have:

\(\mathbf{ =\dfrac{\dfrac{(6\sqrt{x}-x^2\sqrt{x}-3x\sqrt{x}+2x+2)(x-1) }{2} }{4x} }\)

\(\mathbf{P =\dfrac{(6\sqrt{x}-x^2\sqrt{x}-3x\sqrt{x}+2x+2)(x-1) }{8x} }\)

The probability that a randomly selected jury of 12 people is all male is 2.1 × 10⁻⁵.

What is the probability?

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a proposition is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.

An order does not matter so it is a Combination.

There are 16 men and we are going to choose 12 --> ₁₆C₁₂

There are 30 people and we are going to choose 12  --> ₃₀C₁₂

₁₆C₁₂ / ₃₀C₁₂

\(= \frac{16!}{(16 - 12)!} \div \frac{30!}{(30 - 12)!}\)

Area is the entire amount of space occupied by a flat (2-D) surface or an object's shape.

On a sheet of paper, draw a square using a pencil. It has two dimensions. The area of a shape on paper is the area that it occupies.

Consider your square as being composed of smaller unit squares.

The number of unit squares necessary to completely cover the surface area of a specific 2-D shape is used to calculate the area of a figure. Some typical units for measuring area are square cms, square feet, square inches, square meters, etc.

Draw unit squares with 1-centimeter sides in order to calculate the area of the square figures shown below. The shape will therefore be measured.

According to our question-

(7x – 6y) and (3x – 5y
