Hey there!

Your answer is 3(14 + x)

"Three times the" represents multiplying by 3. "the sum of 14 and a number (x)" represents 14 + x, therefore we get 3(14 + x).

A marketing research firm believes that more than half of adults drink mostly either regular or diet soda. To test this claim, Gallup took a nationally representative sample of 2027 adults and asked them about their soda consumption. The survey shows that 950 of those surveyed drink mostly either regular or diet soda. The test statistics for the above hypthesis test for the proportion of adults who drink mostly either regular or diet soda is:________. (Round your answer to two decimal places)

Answers

Answer:

The test statistic is z = -2.82.

Step-by-step explanation:

A marketing research firm believes that more than half of adults drink mostly either regular or diet soda.

This means that the null hypothesis is: [tex]H_{0} = 0.5[/tex]

The alternate hypothesis is: [tex]H_{a} > 0.5[/tex]

The test statistic is:

[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]

In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis, [tex]\sigma[/tex] is the standard deviation and n is the size of the sample.

0.5 tested at the null hypothesis:

This means that:

[tex]\mu = 0.5, \sigma = \sqrt{0.5*0.5} = 0.5[/tex]

Gallup took a nationally representative sample of 2027 adults and asked them about their soda consumption. The survey shows that 950 of those surveyed drink mostly either regular or diet soda.

This means that [tex]n = 2027, X = \frac{950}{2027} = 0.4687[/tex]

Test statistic:

[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]

[tex]z = \frac{0.4687 - 0.5}{\frac{0.5}{\sqrt{2027}}}[/tex]

[tex]z = -2.82[/tex]

The test statistic is z = -2.82.

Which three steps are correct when solving this quadratic equation by completing the square? X^2-10x=39

Answers

Step-by-step explanation:

Any answer that involes,

Step 1: Complete the Square

[tex] {x}^{2} - 10x = 39[/tex]

[tex]( \frac{ - 10}{2} ) {}^{2} = 25[/tex]

[tex] {x}^{2} - 10x + 25 = 64[/tex]

Step 2: Turn the left side into a binomial

[tex](x - 5) {}^{2} = 64[/tex]

Step 3: Solve for x.

[tex]x - 5 = + - 8[/tex]

[tex]x - 5 = 8[/tex]

[tex]x = 13[/tex]

OR

[tex]x - 5 = - 8[/tex]

[tex]x = - 3[/tex]

X=-3 or X=13

A can of paint is a right circular cylinder. The radius of the base is 5 centimeters and the height is 12 centimeters. Find the number of cubic centimeters of paint, in terms of π, contained in a full container.

Answers

Answer:

The answer is 300

The number of cubic centimeters of paint contained in the full jar container is n = 300 and the volume is V = 300π cm³

What is a Cylinder?

A cylinder is a three-dimensional shape consisting of two parallel circular bases, joined by a curved surface. The center of the circular bases overlaps each other to form a right cylinder. The volume of a cylinder is

Volume of Cylinder = πr²h

Surface area of cylinder = 2πr ( r + h )

where r is the radius of the cylinder

h is the height of the cylinder

Given data ,

The volume of a right circular cylinder can be calculated using the formula:

V = πr²h

where V is the volume, r is the radius of the base, and h is the height.

Substituting the given values, we have:

V = π(5 cm)²(12 cm)

V = π(25 cm²)(12 cm)

V = 300π cm³

Hence , a full container of paint contains 300π cubic centimeters of paint.

Answers

Answer: 30 degrees

Step-by-step explanation:

The total is 180 degrees.

there is a right angle on the left. A right angle is 90 degrees.

180 - 90 = 90

There is still 90 degrees left, meaning that the right side is a total of 90 degrees.

2x + x = 3x

x = 90/3

x = 30

Therefore,

x = 30 degrees!

For 120 consecutive days, a process engineer has measured the temperature of champagne bottles as they are made ready for serving. Each day, she took a sample of 8 bottles. The average across all 960 bottles (120 days, 8 bottles per day) was 46 degrees Fahrenheit. The standard deviation across all bottles was 0.8 degrees Fahrenheit. what would be the center line

Answers

Answer:

46° Fahrenheit

Step-by-step explanation:

Center line can be said to be the X double bar. X double bar is the average value we have across all components we're considering. In this question, the X double bar is already given as 960 bottles (if you multiply 120 days by 8 bottles per day) and that it is 46 degrees Fahrenheit.

As such, there exist no reason to want to or have to solve for anything since it's already given.

Therefore the Centre line is 46 degrees Fahrenheit, same as what is given in the question.


Find the radius of a circle in which the central angle, a, intercepts an arc of the given length
a = 30°, s = 9in

Answers

Answer:

17.2 in

Step-by-step explanation:

The formula for arc length is s = rФ.  Here we are to find r.  Solving this formula for r, we get:

r = s/Ф

So, in this problem, r = (9 in) / (π/6) = 54/π in ≈ 17.2 in

Suppose it is known that 23% of students at a certain college participate in a textbook recycling program each semester. Complete parts (a) and (b) below. a. If a random sample of 40 students is selected, do we expect that exactly 23% of the sample participates in the textbook recycling program? Why or why not? Choose the correct answer below. A. We expect that exactly 23% of the sample participates in the textbook recycling program, because that is the percentage of students that participate in the program regardless of sample or population size B. We expect that exactly 23% of the sample participates in the textbook recycling program, because a sample always has the same statistics as the population C. We do not expect that exactly 23% of the sample participates in the textbook recycling program. 23% is a population statistic and you cannot know anything about a sample from the population D. We do not expect that exactly 23% of the sample participates in the textbook recycling program. We do expect that the sample proportion will be close to the population proportion, but it will vary by the sample error from sample to sample b. Suppose we take a sample of 400 students and find the sample proportion participating in the recycling program. Which sample proportion do you think is more likely to be doser to 23% the proportion from a sample size of 40 or the proportion from a sample size of 400? Explain your reasoning. Choose the correct answer below A. The sample with size 40 will be closer to 23% because a smaller sample size has a smaller standard error B. The sample with size 400 will be closer to 23% because a larger sample size has a smaller standard error. C. The sample with size 400 will be closer to 23% because a larger sample size has more variation, D. The sample with size 40 wil be closer to 23% because a smaller sample size has loss variation

Answers

Answer:

D. We do not expect that exactly 23% of the sample participates in the textbook recycling program. We do expect that the sample proportion will be close to the population proportion, but it will vary by the sample error from sample to sample

B. The sample with size 400 will be closer to 23% because a larger sample size has a smaller standard error.

Step-by-step explanation:

The mean of sample can be estimated from the population. However, what we only get is the estimated mean of the sample which isn't the exact figure as that of the population. This slight variation in the mean value of the sample is due to sampling error.

According to the Central limit theorem, increasing the sample size yield a sample mean which continously converges to that of the population mean as the sampling error for such distribution drops lower and lower.

The true statements are:

D. We do not expect that exactly 23% of the sample participates in the textbook recycling program. We do expect that the sample proportion will be close to the population proportion, but it will vary by the sample error from sample to sample  B. The sample with size 400 will be closer to 23% because a larger sample size has a smaller standard error.

The given parameters are:

[tex]\mathbf{P(Recycling) = 23\%}[/tex]

This means that there is a 23% chance that a student in a college participates in textbook recycling

However, it does not mean that the probability is exactly 23% in a sample of 40 students.

This is so because, there may be error in the sampling of the population.

Hence, the true statement is (d)

According to central limit theorem, as the sample size increases, the sample error reduces.

This mean that the probability will be closer to 23% when the sample size increases to 400

Hence, the true statement is (b)
