Answer:
7√3
Step-by-step explanation:
Given the following information,
Short = 7 = Opposite
Angle of elevation =30 degrees
Required
Long (Adjacent)
Using SOH CAH TOA identity
tan theta = 7/long
tan 30 = 7/long
long = 7/tan30
long= 7/1/√3
long = 7√3
Hence the long is 7√3
Answer: The cost is $0.75 more at the retail store.
Step-by-step explanation: A centimeter ruler can measure the difference.
If you use a drawing with the amount if money represented by the length if the line, one line will be 3.90 cm long. The other will be 4.65. Cm. The difference in length is .75 cm

Answer:
Stratified sampling
Step-by-step explanation:
Samples may be classified as:
Convenient: Sample drawn from a conveniently available pool.
Random: Basically, put all the options into a hat and drawn some of them.
Systematic: Every kth element is taken. For example, you want to survey something on the street, you interview every 5th person, for example.
Cluster: Divides population into groups, called clusters, and each element in the cluster is surveyed.
Stratified: Also divides the population into groups. However, then only some elements of the group are surveyed.
In this question:
People divided by groups, for each group(<100, >100<500, >500), a number(not all) is selected, so stratified sampling.
