(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).
Suppose a mango cost x dollar and a apple cost y dollar
there will be an binary system of equation
8*x+3*y=18
3*x+5*y=14.5
so soultions have to x=48/31 y=16/31
D. independent -- Number of Months
dependent -- Total Cost
The dependent Variable depends on the independent variable so, as the number of months change, the total cost changes.
D.36 60 .... because 6 times 6 is 36 and 6 times 10 is 60
