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).
Hello from MrBillDoesMath!
Answer:
3
Discussion:
34 + 2x = 40 => subtract 34 from both sides
(34-34) + 2x = 40 - 34 => as (34-34) = 0 and 40-34 = 6
2x = 6 => divide both sides by 2
x = 6/2 = 3
Check the answer:
Does 34 + 2x = 40 if x = 3 ?
Does 34 + 2(3) = 40 ?
Does 34 + 6 = 40 ? YES! so the answer checks.
Thank you,

The sales tax is 3.49 I think
"x = 2; a = 5; b = 3" A 5 inch tall bamboo shoot doubles in height every 3 days. If the equation y=ab^x, where x is the number of doubling periods, represents the height of the bamboo shoot.
Answer:
7
Step-by-step explanation:
n! Might be 7, and n might be 6. r might also be 6. So 6 - 6= 0! = 1
So I think it might be 7 ÷ 1, which is 7.
