Answer 1

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.

Answer:

Cheryl writes 7 fewer posts than Kevin on a social media site.

Answer the questions to write an algebraic expression. Then evaluate the expression for the given value.

1. Choose a variable to represent the number of posts Kevin writes. Explain why you chose this variable. (2 points)

The expression will be P for "of posts Kevin writes." 

2. Which operation (addition, subtraction, multiplication, or division) applies to this situation? Justify your choice. (2 points)

 The operation I will use is subtraction so P-7.

3. Use your variable and the operation you identified to write an expression for the number of posts Cheryl wrote. (3 points)

Subtraction would be the operation and my expression would be ( P-7 ) which would also be ( 21 - 7 )

4. If Kevin wrote 21 posts, how many did Cheryl write? (3 points)

Cheryl wrote 14 posts, because 21 - 7 = 14

Hope this helps <3

1. We have chosen a variable 'x' to represent the number of posts by Kevin.

2. Subtraction applies to this situation.

3. The number of posts written by Cheryl is (x - 7).

4.  If Kevin wrote 21 posts, Cheryl wrote 14 posts.

What is an equation?

An equation is written in the form of variables and constants separated by the operation of multiplication and division,

An equation states that terms in different forms on both sides of the equality sign are equal.

Multiplication and division do not separate the terms of an equation.

Let, Kevin writes 'x' number of posts,

Therefore, Cheryl writes (x - 7) posts.

We could have chosen any letters for the number of posts Kevin writes,

And as Cheryl writes fewer posts than Keving we subtracted the number.

If Kevin writes 21 posts, 'x' is 21, And hence Cheryl has written,

(21 -7).

= 14 posts.

What is logical equivalence?

A tautology is a claim that is true no matter what the truth values of the propositional variables it includes are.Contradictions and absurdities refer to a group of propositions that are all untrue.It's also known as a contingency when a composite proposition contains neither a tautology nor a contradiction.What does this imply in actuality, though?To make sense of this, go to the following truth table.

Contradiction and tautology

Inconsistency, contradiction, and tautology So a tautology is when every single statement in a column is true, as defined by Oak Ridge National Laboratory, and is often indicated by a bold-faced capital T. When the entire column is untrue, a contradiction, which is often denoted by a boldface capital F, exists.

However, why is this significant?

We may better understand propositional equivalences, or assertions that are equivalent in logical reasoning, by using tautologies and contradictions, which are necessary in establishing or verifying mathematical arguments. Our task will be to confirm the logical equivalentity of propositions like p and q.

Something like choice A has x = 6 repeated; showing that x = 6 leads to both y = 11 and y = -9 at the same time. So this is why choice A is not a function. Choice B has x = 1 repeat, so it's not a function either. Choice C has x = 19 repeated, so it's not a function.

Answer:

A. Cendric is correct because he used the inverse of subtraction and added 4.5

Step-by-step explanation:

To solve for x, all we needed to do was to make x stand alone. To do this, we have to apply addition property of equality. This means we would add 4.5 to both sides for the equation to balance. Thus, we would have z standing alone which equals 3.

Therefore, Cendric was correct because he used the inverse of subtraction of -4.5, which is 4.5 that was later added to both sides of the equation.

Susan Williams has been the production manager of Medical Suppliers, Inc., for the past 17 years. Medical Suppliers, Inc., is a producer of bandages and arm slings. During the past 5 years, the demand for No-Stick bandages has been fairly constant. On average, sales have been about 87,000 packages of No- Stick. Susan has reason to believe that the distribution of No-Stick follows a normal curve, with a standard deviation of 4,000 packages. What is the probability that sales will be less than 81,000 packages

Answers

Answer:

the probability that sales will be less than 81,000 packages is 0.6681

Step-by-step explanation:

Given that;

Average sales μ = 87,000

standard deviation σ = 4,000

x' = 81,000

P( x < 81,000) = ?

so

P( x < 81,000) = P( x - μ / σ )

we substitute

P( x < 81,000) = P( 81,000 - 87000 / 4000 )

P( x < 81,000) = P(  - 6000 / 4000 ) = -1.5

from table;

P( z < 1.5 ) = 0.6681

Therefore the probability that sales will be less than 81,000 packages is 0.6681

Combine the constants by subtracting 2 from both sides.

Combine the variable by subtracting 3n from both sides.

-7/2n = 14

Multiply both sides by 2 to simplify the fraction.

Isolate n by dividing by -7 on both sides.

Given :

Nadia : Preston

Population Last Year 5,589

This Year 5,702

Growth rate:

[(this year population - Last year population) / last year population] * 100%

[(5702 - 5589) / 5589] * 100%

(113 / 5589) * 100%

= 0.0202182 * 100%

= 2.02%

ELM Ridge

Last Year 1,870

This Year 1,926

Growth rate:

[(this year population - Last year population) / last year population] * 100%

[(1926 - 1870) / 1870] * 100%

(56 / 1870) * 100%

The value of 'x' in two similar triangles is 6.46.

What is a triangle?

A triangle is a three-sided closed-plane figure formed by joining three noncolinear points. Based on the side property triangles are of three types they are Equilateral triangle, Scalene triangle, and Isosceles triangle.

We know in similar triangles the ratio of their corresponding sides are equal.

Therefore, The equation to determine the value of 'x' should be,

(2x - 6)/20 = 36/(x + 6).

36(2x - 6) = 20(x + 6).

72x - 216 = 20x + 120.

72x - 20x = 120 + 216.

52x = 336.

x = 336/52.

x = 6.46.

Solve the equation 3x-1 = -7

Answers

Answer: x = -2

Step-by-step explanation:

first, we move the constant to the right.

3x = -7 + 1

then, we calculate that.

3x = -6

finally, we divide both sides.

x = -2

The solution to the equation 3x - 1 = -7 is x = -2.

To solve the equation 3x - 1 = -7, we need to isolate the variable x on one side of the equation.

Here are the steps to solve it:

Step 1: Start with the given equation: 3x - 1 = -7.

Step 2: To eliminate the constant term (-1) on the left side, we can add 1 to both sides of the equation:

3x - 1 + 1 = -7 + 1.

Simplifying, we get: 3x = -6.

Step 3: Now, we want to isolate x, so we need to get rid of the coefficient 3 in front of x.

We can do this by dividing both sides of the equation by 3:

(3x)/3 = (-6)/3.

Simplifying further, we have: x = -2.

Step 4: We have found the solution to the equation: x = -2.

Therefore, the solution to the equation 3x - 1 = -7 is x = -2.
