Answer:
C
Step-by-step explanation:
3(3 + x) = 15 + x
Open bracket
9 + 3x = 15 + x
Collecting like terms
3x - x = 15 - 9
2x = 6
Dividing by 2
x = 6/2
x = 3
Answer:
a.] d) employed individuals aged 25-29
b.] a) Have your earned a bachelor's degree (or higher)?
C.] Categorical
Step-by-step explanation:
According to the scenario described, the population being studied are those aged between 25 - 29 years and who are employed. The study was to determine the level of education of the respondents who happens to fall into the category of being employed and within the 25 - 29 Years age bracket.
The most appropriate question to ask in other to establish if respondent has at least a bachelor's degree is to explicitly ask if the respondent has a bachelor's degree or higher.
C) Categorical : The response to the question will best directly take a 'yes' 'no' format which is a categorical label which could then be transformed into dummy variables for further analysis
Answer:
always
Step-by-step explanation:
yes, there are infinitety many polynomial that have exactly one real root just like your example, to determine the real root first let the real root is a, and the complex roots are b±ic the polynomial satisfy
-9x³ + 19x² + 17 = -(x - a)(x - b - ic)(x - b + ic)
9x³ - 19x² - 17 = (x - a)(x - b - ic)(x - b + ic)
