Complete Question

A random telephone survey of 1021 adults (aged 18 and older) was conducted by Opinion  Research Corporation on behalf of CompleteTax, an online tax preparation and e-filing  service. The survey results showed that 684 of those surveyed planned to file their taxes  electronically (CompleteTax Tax Prep Survey 2010).

a. Develop a descriptive statistic that can be used to estimate the percentage of all  taxpayers who file electronically.  (to nearest whole number)

b. The survey reported that the most frequently used method for preparing the tax return  is to hire an accountant or professional tax preparer. If 60% of the people surveyed had  their tax return prepared this way, how many people used an accountant or professional

tax preparer?

c. Other methods that the person filing the return often used include manual preparation,  use of an online tax service, and use of a software tax program. Would the data for the  method for preparing the tax return be considered categorical or quantitative?

Answer:

a. A descriptive statistic that can be used to estimate the percentage of all taxpayers who file electronically is the measure of frequency, using percentage.

Therefore, we can say that the percentage of all taxpayers who file electronically is 67% (684/1,021 * 100).

b. If 60% of the people surveyed prepared their tax returns by hiring an accountant or professional tax preparer, the number of persons who used professionals is:

= 613 (1,021 * 60%)

c. The data for the method for preparing the tax return would be considered categorical.

Step-by-step explanation:

a) Data and Calculations:

Sample number of adults surveyed = 1,021

Number of those surveyed who planned to file electronically = 684

This means that those who planned to file manually = 337 (1,021 - 684)

b) Descriptive statistics summarize the basic features of the data set.

Categorical data groups data with similar characteristics together instead of using numerical values like quantitative data.

I just did a test the correct answer is c

Step-by-step explanation:

The correct answer is C: Each term in Pattern A is 8 more than its corresponding term in Pattern B.

Sequence is an enumerated collection of objects in which repetitions are allowed and order matters.

Pattern A{0}{6}{12}{18}{24}{30}

Pattern B{0}{2}{4}{6}{8}{10}

The first term in Pattern A is 0, while the first term in Pattern B is also 0. The second term in Pattern A is 6, while the second term in Pattern B is 2.

The third term in Pattern A is 12, while the third term in Pattern B is 4. We can see that each term in Pattern A is 8 more than its corresponding term in Pattern B.

Therefore, the correct answer is C: Each term in Pattern A is 8 more than its corresponding term in Pattern B.

Step-by-step explanation:

The measure of the angle Z is equivalent to 41.7°.

Given is a right angle triangle XYZ.

Using the tangent function, we can write -

tan(Z) = XY/XZ

tan(Z) = 25/28

tan(Z) = 0.89

Z = tan⁻¹(0.89)

Z = 41.7°

Therefore, the measure of the angle Z is equivalent to 41.7°.

Answer:

Number of batches of cookies = 4

Number of batches of brownies = 7

Step-by-step explanation:

Let the number of batches of cookies she made = x

And the number of batches of brownies = y

Total number of batches she made = 11

So the equation representing batches will be,

x + y = 11 ---------(1)

Her recipe for cookies calls for eggs = 1 per batch

So eggs required for x batches of cookies = 1 × x = x

Similarly, her recipe for brownies calls for eggs = 2 per batch

So, eggs required for y batches of brownies = 2y

Total number of eggs required = 18

Therefore, equation will be,

x + 2y = 18 ---------- (2)

Equation (2) minus equation (1)

(x + 2y) - (x + y) = 18 - 11

y = 7

From equation (1),

x + 7 = 11

x = 4

Therefore, number of batches of cookies and brownies she made were 4 and 7.

[tex]P(Tail = 1) = \frac{1}{2}[/tex]

Step-by-step explanation:

Given

[tex]Flips = 2[/tex]

Required

Probability of exactly one tail

This event can be represented as:

(Head and Tail) or (Tail and Head)

In the flip of a coin (penny), the following probabilities exist:

[tex]P(Head) = \frac{1}{2}[/tex]

[tex]P(Tail) = \frac{1}{2}[/tex]

So, the required probability is:

[tex]P(Tail = 1) = (P(Head) * P(Tail)) + (P(Tail) * P(Head))[/tex]

Substitute values for P(Head) and P(Tail)

[tex]P(Tail = 1) = (\frac{1}{2}*\frac{1}{2}) + (\frac{1}{2}*\frac{1}{2})[/tex]

[tex]P(Tail = 1) = (\frac{1}{4}) + (\frac{1}{4})[/tex]

[tex]P(Tail = 1) = \frac{1}{4} + \frac{1}{4}[/tex]

Take LCM

[tex]P(Tail = 1) = \frac{1+1}{4}[/tex]

[tex]P(Tail = 1) = \frac{2}{4}[/tex]

[tex]P(Tail = 1) = \frac{1}{2}[/tex]

It is linear because the ratio of the change in the final cost compared to the rate of change in the price tag is constant.

The statement 'it is linear because the ratio of the change in the final cost compared to the rate of change in the price tag is constant' describes this case.

The ratio of the change is the value that one values changes depending on the corresponding change suffered by another variable.

In this case, the ratio of the change is linear because both variables are directly (proportionally) related and determine a constant equation.

In conclusion, the statement 'it is linear because the ratio of the change in the final cost compared to the rate of change in the price tag is constant' describes this case.

Answer:

[tex]\displaystyle \sin(A-B)=\frac{495}{1073}[/tex]

Step-by-step explanation:

We are given that:

[tex]\displaystyle \tan(A)=\frac{35}{12}\text{ and } \sin(B)=\frac{20}{29}[/tex]

Where both A and B are positive acute angles.

And we want to find he value of sin(A-B).

Using the first ratio, we can conclude that the opposite side is 35 and the adjacent side is 12.

Then by the Pythagorean Theorem, the hypotenuse is:

[tex]h = \sqrt{35^2 + 12^2} =37[/tex]

Using the second ratio, we can likewise conclude that the opposite side is 20 and the hypotenuse is 29.

Then by the Pythagorean Theorem, the adjacent is:

[tex]a=\sqrt{29^2-20^2}=21[/tex]

Therefore, we can conclude that:

So, for A, the adjacent is 12, opposite is 35, and the hypotenuse is 37.

For B, the adjacent is 21, opposite is 20, and the hypotenuse is 29.

We can rewrite sin(A-B) as:

[tex]\sin(A-B)=\sin(A)\cos(B)-\cos(A)\sin(B)[/tex]

Using the above conclusions, this yields: (Note that since A and B are positive acute angles, all resulting ratios will be positive.)

[tex]\displaystyle \sin(A-B)=\Big(\frac{35}{37}\Big)\Big(\frac{21}{29}\Big)-\Big(\frac{12}{37}\Big)\Big(\frac{20}{29}\Big)[/tex]

Evaluate:

[tex]\displaystyle \sin(A-B)=\frac{735-240}{1073}=\frac{495}{1073}[/tex]

Answer:

.B.An orthocenter can be outside of its triangle

Step-by-step explanation:

The orthocenter of a triangle is the intersection of the point drawn perpendicular from the vertices of the triangle. While normal equilateral triangles for instance have their point of intersection drawn inside the triangle, the orthocenter of a triangle of an obtuse triangle is outside of the triangle. A right angled triangle has its orthocenter drawn at the vertex of the right angle and really inside the right angled triangle.
