Answer:
B. Start Fraction 81 a superscript 4 baseline over b superscript 2 baseline c superscript 3 baseline End Fraction
Explanation:
Interpreting the question mathematically, we have;
(3a)⁴b^-2c³)
= 81a⁴×1/b²×c³
= 81a⁴c³/b²
This can be interpreted as Start Fraction 81 a superscript 4 baseline over b superscript 2 baseline c superscript 3 baseline End Fraction
Answer:
B. The study is an observational study because the study examines individuals in a sample comma but does not try to influence the response variable.
Explanation:
Observational studies are studies in which the researchers try to observe the effect of a diagnostic test, treatment, and risk factor without making any change in who is exposed to it and vice-versa.
