300=14(F+2)^2/3 find F and round to the nearest whole number.

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!

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:

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)

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.

Answer:

w=2

Step-by-step explanation:

-14w + 21 = 1 - 4w

-10w + 21 = 1

-10w = -20

w = -20/-10

w=2

Answer:

20 - 10 W = 0

-7 (2w - 3) = 1 - 4w

21 - 14w = 1 - 4 w

w = 2

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.

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

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.
