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.
information about the age of the respondents is missing, so i have attached it.
Answer:
Option A: We are 95% confident that the interval 29.7215 to 30.5029 includes the population mean age of all respondents.
Step-by-step explanation:
From the attached information given, we see that under the 95% Confidence interval column, that the corresponding mean age of all respondents is the interval 29.7215 to 30.5029.
Now, the mean is population mean because it's the mean of all the respondents in the population.
Thus, the correct answer is;
We are 95% confident that the interval 29.7215 to 30.5029 includes the population mean age of all respondents.

If a quadrilateral has 4 equal sides and 4 equal angles, then it is a square.
If a figure is a square, then each of its angles must measure 90 degrees.
If a quadrilaterál has 4 equal sides and 4 equal angles, then each of its angles must measure 90 degrees.
If a quadrilateral has 4 equal sides and 4 equal angles, then none of its angles measures 90 degrees.
If all four angles in a quadriateral measure 90 degrees, the quadrilateral is a square.
If all four angles in a quadriateral measure 90 degrees, the quadrilateral cannot be a square.

The value of an ambulance depreciated by 17.5% from the purchase price of $35,400 a
year ago. What is its current value?
Answer:
29,205
Step-by-step explanation:
100% - 17.5% = 82.5%
82.5% * 35,400 = answer
make percent a decimal
.825 * 35,400 = 29,205
29,205 is answer
The required current value of the ambulance is given as $29,205.
What is the percentage?The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.
Here,
The value of an ambulance depreciated by 17.5% from the purchase price of $35,400 a year ago.
Current price = 35400[1 - 0.175]
Current price = $29,205
Thus, the required current value of the ambulance is given as $29,205.

w = 4
L = 7
Step-by-step explanation:
L = length of rectangle
w = width of rectangle
L = 3 + w
A = 28
A = L*w
=(3+w) * w
28 = 3w + w^2
w^2 + 3w - 28 = 0
w^2 + 7w - 4w - 28 = 0
w ( w + 7 ) - 4 ( w + 7 ) =0
( w - 4 ) ( w + 7 ) = 0
w = 4. and w = -7
take the postive value, w = 4
therefore L= 3+4 = 7

Which equation represents the graph shown?
Step-by-step explanation:
The graph is a linear equation starting at 0.
form y = mx + b.
starts at 0, so b = 0, so the 2nd and 3rd choices are incorrect.
change in y/change in x is the slope,
and you can see it goes up about 35 in the y direction for every 1 in the x, so the slope is 35.
so it's the first answer.
The linear equation of the graph is y = 35x. So, the option first is correct.
What is a linear equation?A linear equation is an equation in which the highest power of the variable is always 1. The standard form of a linear equation in one variable is of the form y = mx + b.
The graph is a linear equation origin at 0.
Since b = 0, the 2nd and 3rd choices are incorrect.
The slope = change in y/change in x
Here, we can see that it goes up about 35 in the y-direction for every 1 unit of in the x, so the slope is 35.
so the first answer is correct which is y = 35x.

Please help me solve for angle B!!
I believe it is 50 degrees
Explanation:
180-115 = 65 degrees
Since the base angles of of an isosceles triangle are equal,
Angle C =angle A= 65 degrees
65 times 2 = 130
180-130=50
50 degrees=measure of angle B

I hope my answer helps even though I am in middle school :)
The required percent decrease in the price of the skateboard is 40%.
The original price for its Extreme Skate Board was $84.50. The sale price for the skateboard is $50.70. What is the percent decrease in the price of the skateboard is to be determined.
The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.
Here,
Original price = $84.50
sale price = $50.70
Percent decrese = 84.50-50.70/84.50 × 100 = 40%
Thus, the required percent decrease in the price of the skateboard is 40%.

Since you know both triangles are congruent, you can say that the corresponding sides are equal. For example, you can say:
17x+3 = 57
because they are corresponding sides of both triangles. To further solve the equation:
17x = 54 --> x = 54/17 --> 3 3/17
Same thing for Y. lines PX and FD are congruent, so, you can say:
4y-3 = 54
4y=57
y= 14.25
