Answer:

This is a stratified random sample because a separate random sample is selected from each class

Explanation:

Stratified random sampling is an appropriate method when the population consists of mixed characteristics and you would like to ensure that every characteristic is proportionally represented in the sample. In this example, the population is the students from Central High School and the mixed characteristics are the different classes such as Freshman students, Sophomore students, Juniors and Seniors.

After the population is divided into subgroups based on characteristics, from the overall proportion of the population, you calculate how many people should be sampled in each subgroup. Random or systematic sampling can then be used to select a sample from each subgroup.

Mark already decided Century Industries is the best option to take for the trailers but needs to influence his point of view to his family members. In other words, Mark will be the gatekeeper between his family business and Century Industries.

NemiM [27]

Answer:

$671,300

Explanation:

The calculation of adjusted basis in the building is shown below:-

Adjusted basis = Original cost of the property + Cost of capital improvements - Depreciation claimed

= $750,000 + $50,000 - $128,700

= $800,000 - $128,700

= $671,300

Therefore for computing the adjusted basis we simply add original cost of the property with cost of capital improvements and deduct depreciation claimed.

What aspects of managing your account were probably more difficult before online banking was available?
sveticcg [70]

Answer:

One of the main advantages of online banking is that you can access information about your account immediately and from anywhere. Before online accounts were available, you had to go to a bank or ATM on some specific cases if you wanted to carry out any type of transaction, e.g. pay a service or transfer money. Online accounts make it less likely for a person to go to a bank, e.g. in order to get a loan, I did it all online, I didn't even need to go to the bank.
