Answer:
The answer is (d)= Selecting a simple random sample from each of a given number of strata formed from the elements in the population.
Stratified random sampling is a sampling method where the population has a number of distinct categories. The population can be organized into separate strata and each stratum is then sampled as an independent sub-population out of which individual elements can be randomly selected. In this case, each unit in a stratum, that is, each element in a group has the chance of being selected into the sample and there is adequate representation of minority sub-groups. With Stratified sampling, the best result occurs when elements within strata are internally homogeneous.

This is an acute triangle
Answer:
a = (4/3)b
Step-by-step explanation:
The governing equation here has the form y = kx, where k is the constant of proportionality.
Let's rewrite that as a = kb, and then substitute -4 for a and -3 for b:
-4 = k(-3), or k = 4/3
Then a = (4/3)b
