Answer:
Step-by-step explanation:
f(x) = (x-4)(x+1-6i)(x+1+6i)
= (x-4)((x+1)²-(6i)²)
= (x-4)((x²+2x+1)-(-36))
= (x-4)(x²+2x+37)
= x³-2x²+29x-148

Step-by-step explanation:
Which is greater, 4/5 or 75%?*
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%.
Hope this helps! :)
What is the equation of the line whose slope is 1/3 and y-intercept is -4?
Question 1 options:
y=−4x+13
y=13x−4
y−4=13x
3y=−4x
Answer:
y=1/3x-4
Step-by-step explanation:
the slope-intercept format of the line is y=mx+b, where m is the slope and b is the y intercept.
we are given the slope (1/3) and the y intercpet (-4).
substitute the numbers into the equation
y=1/3x-4
the answer is y=1/3x-4

9514 1404 393
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
3n = 51 . . . . . . . . . . . . subtract 129
n = 17 . . . . . . . . . . divide by 3

. Three professors examined awareness of four widely disseminated retirement rules among employees at University of Utah. These rules provide simple answers to questions about retirement planning. At the time of the investigation, there were approximately 10,000 benefited employees, and 3,095 participated in the study. Demographic data collected on these 3,095 employees included gender, age (years), education level (years completed), marital status, household income ($), and employment category.(30pts)(a) Describe the population of interest.(b) Describe the sample that was collected.(c) Indicate whether each of the demographic variables mentioned is categorical or numerical.
Answer:
a) The population of interest = 10,000 benefited employees. It includes all benefited employees.
b) The sample collected = 3,095. These are the benefited employees who participated in the study.
c) Indication of demographic variables as categorical or numerical:
Demographic data: Categorical or Numerical
Gender = Categorical
Age (years) = Numerical
Education level = Numerical
(years completed)
Marital status = Categorical
Household income ($) = Numerical
Employment Category = Categorical
Step-by-step explanation:
a) Data and Calculations:
Population of interest = 10,000 benefited employees
Sample = 3,095 participants
Demographic data:
Gender
Age (years)
Education level (years completed)
Marital status
Household income ($)
Employment Category
b) A variable is numerical value (e.g. length, test scores, etc.). It is a continuous variable. A categorical variable assumes a limited or fixed number of possible values, or it is categorized in groups.

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
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.
Use the ordered pairs shown in the table below.
X:20,30,40,50
Y:30,45,60,75
which equation represents the data in the table?
A: y=1.5y
B:x=1/3y
C:x=1.5y
D:y=2/3x
Answer:
A.
Step-by-step explanation:
if you multiply 20 times 1.5 you get 30. If you multiply 30 times 1.5 you get 45. If you multiply 40 times 1.5 you get 60. If you multiply 50 times 1.5 you get 75 . meaning that y equals 1.5

what is the value of x?
[tex]3x + 5y = 45[/tex]
Answer:
x = -5/3y + 15
Step-by-step explanation:
Step 1: Subtract -5y from both sides.
3x+5y+−5y=45+−5y
3x=−5y+45
Step 2: Divide both sides by 3.
3x divided by 3 = −5y+45 divided by 3
x = -5/3y + 15
