Answer:
(D) A stratified random sample
Step-by-step explanation:
A stratified random samples are samples that involves the use of stratified random sampling (or stratification) which involves the partition or division of a population into smaller subgroups (called strata). The division is done based on some shared characteristics and attributes. The case above is a stratified random sample because it involves the division of shoreline(population) into 100-foot plots(stratas or subgroups).
I'm pretty sure its B but I would double check before you put the answer in :)
Blake has 25 CD's.
25 times 3 = 75
75 + 7 = 82
Joel has 82 CD's.
If Joel has twice as many as Mariella, then divide 82 by 2 and you get 41.
Mariella has 41 CD's.
