Young Professional magazine was developed for a target audience of recent college graduates who are in their first 10 years of a business or other professional career. The magazine has been fairly successful and the publisher is interested in expanding the publication's advertising base. As a recent hire into the marketing department at the magazine, you have been asked to help develop a survey asking readers demographic information and questions about their interests. Your survey results will be used to help the magazine choose articles of interest and provide advertisers with a profile of subscribers.The culmination of your work will be a presentation of your findings to management. Therefore, you not only have to present summary data, but must also be able to explain the results in a manner that is accurate and easy to understand.After running your analysis, the software returns the following information about the age of the respondents:Which statement should you use to explain the 95% confidence interval to management?a. We are 95% confident that the interval 29.7215 to 30.5029 includes the population mean age of all respondents.b. We are confident that 95% of our readers have ages between 29.7215 to 30.5029.c. There is a 95% probability that the population mean age of all respondents lies within the interval 29.7215 to 30.5029.d. We are 95% confident that the interval 29.7215 to 30.5029 includes the sample mean age of all respondents.

Answer: it should be 11.infinite 6

Step-by-step explanation:7x2=14+21=35

35/3 = 11.infinite 6

So basically 11.6

Answer:

The total number of sets is 2,640.

Step-by-step explanation:

The number of marbles in the bag are:

S = {3R, 5G, 1L, 2Y and 6O}

There are a total of N = 17 marbles in the bag.

Four marbles are randomly selected.

Assume that the selection was without replacement.

It is provided that two of the marbles are green.

And the remaining two are non-green.

A sample of the selection is as follows:

G, G, _, _

The two green marbles can be selected in 5 × 4 = 20 ways.

So, the remaining two marbles cannot be green.

That leaves us with: 3R, 1L, 2Y and 6O = 12 marbles.

The third marble can be selected in 12 ways.

And the fourth marble can be selected in 11 ways.

So the number of combinations of selecting 4 marbles such that 2 are green and 2 are non-green is:

Total number of sets = 5 × 4 × 12 × 11 = 2640

Thus, the total number of sets is 2,640.

[tex]\sqrt5[/tex]Answer:

Sin^2 x + Cos^2 x = 1

Sin^2 x = 1 - 4 / 9 = 5 / 9

Sin x = [tex]\sqrt5[/tex]  / 3

Tan x = Sin x / Cos x = ([tex]\sqrt5[/tex]  / 3) /  (2 / 3) =  [tex]\sqrt5[/tex]  / 2

Answer:

No, triangle B is a reflection of triangle A.

Step-by-step explanation:

The points of triangle A are reflected across the dotted line. So as a result triangle B is a reflection of triangle A.

Answer:

No

Step-by-step explanation:

Its a reflection because even if you did rotate it it would never be in that orientation.

Answer:

volume  = L*B*H

Step-by-step explanation:

SO,

Volume of the box = L*B*H

OR, Volume of the box = 10*12*3

thus, Volume of the box =360

Answer:

I wanna say its Hence n (Q) =7

I may be mistaken

Answer:

6

Step-by-step explanation:

The set is made up of 6 elements. Therefore, the cardinal number is 6.

Answer:

The constant rule being followed is that the sum of x and y in every case is 5

Since the sum of x and y is 5, we can say that the value of y is 5-x

So we can define a function for this rule:

f(x) = 5 - x

Answer:

Step-by-step explanation:

From the table we see that:

Considering the above observations we can put equation:

Answer:

A certain shade of pink us created by adding 3 cups of red paint to 7 cups of white paint

Step-by-step explanation:

Constant of proportionality is the constant value of the ratio of two proportional quantities x and y; usually written y = kx, where k is the factor of proportionality.

To make color pink,

for every 3 cups of red , we need 7 cups of white.

Let 'r' be the cups of red required

let 'w' be the cups of white required

so , as per the question

for 3 r we need = 7 w

r = 7/3 w

so, 7/3 is constant of proportionality

Answer:

2%

Step-by-step explanation:

Step-by-step explanation:

Hi

a+b > a-b

<=> a+b-a = b > a-b-a=-b ** subtract a **

<=> b+b > 0 ** add b **

<=> 2b > 0 ** divide by 2 **

<=> b > 0

so (E) is the right answer

Thanks

Answer:

Y= 43, x=137, z=137 total is 360

Answer:

T,F,T,F,T

Step-by-step explanation:

1. It crosses it there becuase 4(0)-15=-15 for y

2: both top and middle answers are -23, so continuous

3: it increases over that period because the exponent keeps getting bigger

4: No, its not decreasing because -12 plugged in is far less than -23 when -2 is plugged in, meaning its increasing

5: There is no number that would cause an imaginary number or make you divide by zero, meaning all real numbers are fine.

Answer:

The answer would be -12x^2-4x+6

Step-by-step explanation:

This is the simplest form it could get since you subtract the two x^2 together.

Answer:

False

Step-by-step explanation:

To find the opposite of an integer, we just change its sign. If it is negative, change to positive. If it is positive change to negative. Opposite integers are the pairs of integers that have the same absolute value, or the same distance from zero. The sum of two opposites is always zero.

Hope this helps :)

Convert to common denominator then subtract the numerator

Answer:

Jessica: 10 orders

Lamar: 18 orders

Kareem: 36 orders

Step-by-step explanation:

Let's first designate each person with a letter.

The number of orders served by Jessica can be designated as [tex]J[/tex]

The number of orders served by Kareem can be designated as [tex]K[/tex]

The number of orders served by Lamar can be designated as [tex]L[/tex]

We know that they all served a total of 64 orders. This can be expressed as the sum of their orders equaling 64.

[tex]J+K+L=64[/tex]

We also know that Jessica served 8 fewer orders than Lamar. This can be expressed as the number of orders served by Jessica, [tex]J[/tex], being equal to Lamar's orders [tex]L[/tex] minus 8.

[tex]J = L-8[/tex]

Fianlly, we know that Kareem served twice as many orders as Lamar. This can be expressed as the number of order's served by Kareem, [tex]K[/tex], being 2 times Lamar's orders [tex]L[/tex].

[tex]K = 2L[/tex]

With these 2 equalities, we can substitute [tex]J[/tex] and [tex]K[/tex] in our original equation,

[tex]J+K+L=64[/tex]

with their values expressed as a subtraction or multiplication of [tex]L[/tex].

[tex]J[/tex] will be substituted with [tex]L-8[/tex], and [tex]K[/tex] will be substituted with [tex]2L[/tex].

[tex]J+K+L=64[/tex]

With substitutions:

[tex](L-8) + 2L + L = 64[/tex]

We can simplify this by combining the L-terms:

[tex]L + 2L + L -8 = 64\\4L - 8 = 64[/tex]

Next, we'll add 8 to both sides.

[tex]4L = 72[/tex]

Divide both sides by 4:

[tex]L = 18[/tex]

Thus, Lamar served 18 orders.

Using our expressions, we can find how many orders the others served.

Jessica:

[tex]J = L-8\\J = 18 -8\\J = 10[/tex]

Jessica served 10 orders.

Kareem:

[tex]K = 2L\\K = 2*18\\K = 36[/tex]

Kareem served 36 orders.

Answer:

it's true 0 divided by 2 is 0 and 2 divided by 0 is still 0

Let the number of men and the number of women in the beginning be x and y

Now,[tex]\sf \frac{x} {y} =\frac{5}{2} \\\\\sf

=2x=5y \\\\\sf

=x=\frac{5y}{2}[/tex]

Now, In 2nd case,

No. Of men=x-63 and no. Of women =y-12

Now,the ratio becomes[tex] \frac{x-63}{y-12}=\frac{7}{4} \\\\\sf

=4(x-63)=7(y-12) \\\\\sf

=4x-252=7y-84 \\\\\sf

Putting,\:x=\frac{5y}{2}\:in\: 4x-252=7y-84\:we\: get, \\\\\sf

10y-252=7y-84 \\\\\sf

=10y-7y=252-84 \\\\\sf

=3y=168 \\\\\sf

=y=56 \\\\\sf

=\boxed{Y=56}

[/tex]

Now,we have, 2x=5y

Putting the value of Y=56 in 2x=5y,we get,

[tex]\sf 2x=5\:x\:56 \\\\\sf

x=\frac{5\:x\:56}{2} \\\\\sf

x=\frac{5\:x\: \cancel{56}\:\:28}{ \cancel{2}} \\\\\sf

=x=5\: x\: 28 \\\\\sf

x=140 \\\\\sf

\boxed{x=140}

[/tex]

Hence, the number of men was 140 and the no. of women was 56
