[tex]3x + 5y = 45[/tex]
Answers
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

Answers
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

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%.
