Answer:
n = 17
Step-by-step explanation:
The angle sum theorem tells you the angles add up to the linear angle of 180°.
(3n -5)° + 90° +44° = 180°
3n + 129 = 180 . . . . . . . . . . collect terms

In a study of speed dating, female subjects were asked to rate the attractiveness of their male dates, and a sample of the results is listed below (1not attractive; 10extremely attractive). Find the range, variance, and standard deviation for the given sample data. Can the results be used to describe the variation among attractiveness ratings for the population of adult males
Answers
Answer:
[tex]Range = 7[/tex]
[tex]s^2 = 3.53[/tex] -- Variance
[tex]s = 1.88[/tex] --- Standard Deviation
No, it can not be used
Step-by-step explanation:
Given
I'll use the data in the attachment to answer the question.
(a) Range:
[tex]Range = Highest - Lowest[/tex]
From the attached data.
[tex]Highest = 10[/tex]
[tex]Lowest = 3[/tex]
So:
[tex]Range = 10 - 3[/tex]
[tex]Range = 7[/tex]
(b) Variance:
We start by calculating the mean:
[tex]\overline x = \frac{\sum x}{n}[/tex]
[tex]\overline x = \frac{5 + 8 + 3 + 8 + 6 + 10 + 3 +......+ 8+8+7}{26}[/tex]
[tex]\overline x = \frac{171}{26}[/tex]
[tex]\overline x = 6.58[/tex] --- approximated
The sample variance is then calculated using:
[tex]s^2 = \frac{\sum(x_i - \overline x)^2}{n-1}[/tex]
This gives:
[tex]s^2 = \frac{(5-6.58)^2+(8-6.58)^2+(3-6.58)^2+(8-6.58)^2+..............+(8-6.58)^2+(8-6.58)^2+(7-6.58)^2}{25-1}[/tex]
[tex]s^2 = \frac{88.3464}{25}[/tex]
[tex]s^2 = 3.53[/tex] --- approximated
(c) Standard Deviation.
This is calculated as:
[tex]s = \sqrt{s^2[/tex]
Substitute 3.53 for [tex]s^2[/tex]
[tex]s = \sqrt{3.53}[/tex]
[tex]s = 1.88[/tex] --- approximated
(d) No, it can not be used because the selected sample is too small to represent the total population and as such the result of the measure of variations can not be used.

b) The sample collected = 3,095. These are the benefited employees who participated in the study.
c) Indication of demographic variables as categorical or numerical:
Demographic data: Categorical or Numerical
Gender = Categorical
Age (years) = Numerical
Education level = Numerical
(years completed)
Marital status = Categorical
Household income ($) = Numerical
Employment Category = Categorical
Step-by-step explanation:

Which is greater, 4/5 or 75%?*
Answers
Answer:
4/5
Step-by-step explanation:
4/5 is equal to 80%, which is more than 75%. How you can figure this out is that you can determine 4/5 of 100, (divide 100 by 5 and pick the 4th part,) to get 80. 75% is equal to 3/4, so divide 100 by 4 and shoose the 3rd part, 75. Therefore, 4/5 is greater than 75%.
