Answer:
1. option D
2. option A
Step-by-step explanation:
Independent samples are samples that are selected randomly so that its observations do not depend on the values other observations. Thus, this sampling is independent. The sampling is independent because an individual selected for one sample does not dictate/affect which individual is to be in the second sample.
The variable is qualitative because it is an attribute classification. A qualitative variable are variables that are not numerical. It describes data that fits into categories (personality type).
Answer:
C. I hope this helps!
Step-by-step explanation:
Answer:
The values for a, b c are:
a = 1
b = -4
c = 12
Step-by-step explanation:
In order to make it in standard form we need to swap the "-12" to the left side. When we swap numbers from one side to the other of an equation we need to invert their operation so the equation will still be valid, so in this case the number "-12" will go to the left side as "+12". We have:
x² - 4x + 12 = 0
The values for a, b c are:
a = 1
b = -4
c = 12
