Given that the depth varies directly with amount of rainfall, then we shall have:
let d be the depth and r be the rainfall amount
dαr
thus
d=kr
where, k is the constant of proportionality, thus the formula will be:
d=kr
For this item, we represent first the proportionality constant by the variable k. Being directly proportional to both b and c, these variable will be in numerator and d will be in the denominator. That is,
a = kbc / d
Substituting the known values,
400 = k(16)(5) / (2)
The value of k is 10. The equation that models the relationship is therefore,
a = 10bc/d
Answer:
The individuals are observed the exact way they act in real life.
Step-by-step explanation:
There are two main types of studies in research; one is controlled or experimental and the other is observational.
In observational studies, the individuals participating in study are not manipulated or intervened or controlled in any way by the researcher.
Hence the statements best describes a characteristic of an observational study is the individuals are observed the exact way they act in real life !
