Find The Volume Of A Cylinder Either Enter. An Exact Answer In Terms Of Pie Or 3.14 Please Help Me

Answers

Answer 1
128 pi

To find the area of a cylinder, we multiply the area of the base times it’s height. For a cylinder the base is a circle so we use
pi r^2 to find it. In this problem the radius or r = 4 so the area of the base equals 16 pi. The height is 8. So we multiply these two to get the answer of 128 pi

Step-by-step explanation:

The independent variable is the one displayed on the horizontal axis: pounds. The dependent variable is the one shown on the vertical axis: cost.

Then the ordered pair shown represents ...

   (pound, cost) = (0.65, 2.20)

That is, the cost of 0.65 pounds is $2.20. The cost per pound is found by dividing cost by pounds:

  price per pound = $2.20/0.65 lb

which of the following is a number where the digit 2 represents 1/10 the value of the digit 2 in the number 1,947.5286​

Answers

Answer:

0.002

Step-by-step explanation:

the digit "2" in this equation represents 0.02 or also 2/100

1/10 of 2/100 would be like multiplying 1/10 and 2/100 and that would get us 2/1000

2/1000 is also 0.002

0.002 is the value of the digit 2 in the number 1,947.5286​.

What is number?

A number is a mathematical object used to count, measure, and label. The original examples are the natural numbers 1, 2, 3, 4, and so forth. Numbers can be represented in language with number words.

here we have,

the number 1,947.5286​.

the digit "2" in this equation represents 0.02 or also 2/100

1/10 of 2/100 would be like multiplying 1/10 and 2/100

and that would get us 2/1000

i.e.

2/1000 is also 0.002

Hence, 0.002 is the value of the digit 2 in the number 1,947.5286​.

Answers

Answer:

Step-by-step explanation:

A random sample of 500 registered voters from one state was obtained. The party affiliation and sex of each voter was recorded and is listed in the following table. (Follow standard statistical rounding rules for all computations.)

a) A journalist who writes for a statewide newspaper wants to construct a confidence interval for the true proportion of registered voters that are affiliated with Party X. Verify that all requirements for constructing such a confidence interval are met.


b) Construct a 99% confidence interval for the true proportion of registered voters that are affiliated with Party X. Show all work. (Hint: the critical value, the margin of error, p, q, the computation, etc.)


c) The Governor of the state believes that a majority of all registered voters in the state are affiliated with Party X because the confidence interval includes values greater than 50% Does the data in the table support the Governor’s belief? Justify your answer.

Answers

Using the z-distribution, it is found that:

a) There are more than 10 successes and 10 failures in the sample, hence the conditions are met.

b) The 99% confidence interval for the true proportion of registered voters that are affiliated with Party X is (0.43, 0.546).

c) Since the lower bound of the interval is below 50%, the data in the table does not support the Governor's belief.

Item a:

The requirement is that there are at least 10 successes and 10 failures in the sample.

244 out of 500 voters are affiliated with party X, hence 500 - 244 = 256 are not, meaning that there are more than 10 successes and 10 failures in the sample, hence the conditions are met.

Item b:

In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]\alpha[/tex], we have the following confidence interval of proportions.

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which z is the z-score that has a p-value of [tex]\frac{1+\alpha}{2}[/tex].

244 out of 500 voters are affiliated with party X, hence:

[tex]n = 500, \pi = \frac{244}{500} = 0.488[/tex]

99% confidence level, hence[tex]\alpha = 0.99[/tex], z is the value of Z that has a p-value of [tex]\frac{1+0.99}{2} = 0.995[/tex], so [tex]z = 2.575[/tex].

The lower limit of this interval is:

[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.488 - 2.575\sqrt{\frac{0.488(0.512)}{500}} = 0.43[/tex]

The upper limit of this interval is:

[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.488 - 2.575\sqrt{\frac{0.488(0.512)}{500}} = 0.546[/tex]

The 99% confidence interval for the true proportion of registered voters that are affiliated with Party X is (0.43, 0.546).

Item c:

Since the lower bound of the interval is below 50%, the data in the table does not support the Governor's belief.

Answers

Answer:

2x-5y=10 in slope intercept form is y=2/5x-2. The x intercept would be 5 and the y intercept would be -2. The slope is 2/5.

Step-by-step explanation:

Think about the axis for a moment. You have the y-axis and the x-axis. The y-axis crosses the x-axis at y=0. Consequently the graph must also cross the x-axis when its equation has its y-value set to 0.

Likewise the graph will cross the y-axis when x=0

Marques was out at a restaurant for dinner when the bill came. He wanted to leave a tip of 32%. What number should he multiply the cost of the meal by to find the total plus tip in one step?​

Answers

Answer:

1.32

Step-by-step explanation:

1.32

The answer is 1.32

For this problem, percentage can be looked at as a fraction out of 100:

The total = 100/100 or 100% and the tip of 32% is 32/100. 32/100 + 100/100 = 132/100 which equals 1.32

it is made smaller so any values smaller than 15cm but in ratio of 4:5 can be answer

Answer:

15 cm is the new dimensions of new photograph

Step-by-step explanation:

initial dimension of shorter side = 8 cm

initial dimension of longer side = 10 cm

Answer:

y = 8.48x + 108.92227.64236.12

Step-by-step explanation:

According to given we have (x, y) pairs:

(11, 202.2) and (16, 244.6)

Work out the equation of the line.

Find the slope:

m = (244.6 - 202.2)/(16 - 11) = 8.48

Find the y- intercept using one pair of coordinates:

202.2 = 8.48*11 + bb = 202.2 - 93.28b = 108.92

The line is:

y = 8.48x + 108.92

Find the value of y when x = 14 and x = 15:

y = 8.48*14 + 108.92 = 227.64y = 8.48*15 + 108.92 = 236.12

Answers

Answer:

25-10  (25 - A and 10 - B)

Step-by-step explanation:

25 - 10 equals the 15 point margin

25 plus 10 equals the 35 point score combined

Hope it helps

Answer:

25 to 10

First of all, you'd have to write an equation.

            35                   =       (x+15)        +    x

total number of points       Team A         Team B

Subtract 15 from both sides.

20 = 2x

Divide.

20/2 equals X=10

Then you would add 15 to 10 and that would be Team A's score, therefore 25, Team B's is 10.

ILL GIVE BRAINLIEST In 5 sentences, describe integrity in your own words, using the following excerpt as a guide.If you're a new student (or can think back to when you were), you probably remember being given some information about your school's academic honesty policies during the first few days of classes. This information likely addressed, among other things, the school's requirements for submitting original work, policies regarding cheating, and expectations of student behavior. In giving you this information, your school wasn't suggesting you'd cheat; rather, they merely wanted to inform you that they expect all students to act with a certain degree of integrity.Integrity is a term used to describe a person's level of honesty, moral commitments, and willingness to do what's right. For example, we expect our doctors to be honest with us about diagnoses, won't try to prescribe medications we don't need, and will generally work in the best interest of our health and well-being. We expect this because, in most societies, doctors are perceived to be people of great integrity with strong moral compasses.Conversely, if your doctor didn't have any integrity, he or she might be strongly influenced by drug companies or bribes and might talk you into getting tests or procedures you don't need. When this happens, society takes a dim view of that personand in some cases legal charges are broughtbecause he or she was expected to act with integrity.Let's review. In general, integrity is a word used to describe a person's commitment to honesty and a willingness to do what's right. For example, a person who abstains from cheating, lying, or stealing would be considered to be a person who acts with great integrity. In most societies, integrity is an important aspect of culture and contributes to the strength of a community.In academic environments, for example, students are expected to avoid plagiarism and submit work that is entirely their own. Other areas where integrity is important include the legal and justice systems and politics. Despite its importance, though, universal definitions or understandings of integrity can be difficult to locate. This is often because the concept of integrity is a social construct, which is subjective and tends to change as societies and cultures evolve.
