Answer: Random Sampling.

Explanation:

It is a method of sampling a population by selecting a sample unit based on chance, and also based on non-zero probability.

Random sampling is easier to use as it helps to get generalized samples from a large group.

There are 4 types of random sampling.

•Simple random sampling.

•Systematic random sampling.

•Stratified random sampling

•Cluster random sampling.

"Made in the USA remains shorthand for reliability"
Gala2k [10]

The correct answers to these open questions are the following.

1. Do you think that the business executive who made this statement would be in favor of or against free trade? What makes you think so?

What I think is that times are changing and are very different from the time of "Made in America."

In this modern-time, globalization rules, and free trade are the direct consequence of globalization. Many American companies have decided to go abroad and built fabrics and industrial plants in other countries because in those developing countries they pay low salaries and can get more profits selling their products. American companies have been greedy too.

2. What do you feel about the number of imported items you can buy in stores? How might free trade affect these numbers?

As I mentioned above, it is part of free trade in a globalized world. Yes, the United States imports many things, but let's remember that the US also exports many goods to other countries. So this is call balance, in which countries negotiate to have a balance in trade. Countries export, yes, but they also have to import goods, so all the countries win.

The best example is the free trade agreement called NAFTA, now USMCA, between México, Canada, and the United States.

A Temporal Investigation of Crash Severity Factors in Worker-Involved Work Zone Crashes: Random Parameters and Machine Learning
Nostrana [21]

A Temporal Investigation of Crash Severity Factors in Worker-Involved Work Zone Crashes: Random Parameters and Machine Learning Approaches:

Reason:

In the context of work zone safety, worker presence and its impact on crash severity has been less explored. Moreover, there is a lack of research on contributing factors by time-of-day. To accomplish this, first a mixed logit model was used to determine statistically significant crash severity contributing factors and their effects. Significant factors in both models included work-zone-specific characteristics and crash-specific characteristics, where environmental characteristics were only significant in the daytime model. In addition, results from parameter transferability test provided evidence that daytime and nighttime crashes need to be modeled separately. Further, to explore the nonlinear relationship between crash severity levels and time-of-day, as well as compare the effects of variables to that of the logit model and assess prediction performance, a Support Vector Machines (SVM)

What is meant by machine learning approach?

Machine Learning is an AI technique that teaches computers to learn from experience. Machine learning algorithms use computational methods to “learn” information directly from data without relying on a predetermined equation as a model.

Urea is a ___ substance​
Vanyuwa [196]

Answer:

Urea is a <u>nitrogenous</u> substance​

Explanation:

Urea is a substance that is formed in the body during the processing of proteins and nitrogen compounds in the liver, and that we generally excrete through urine and sweat. If it is not eliminated properly, the levels of urea in the blood rise above normal (uremia) and this causes health problems that especially affect the liver - the organ responsible for processing proteins - and the kidneys (which must filter the final waste product), and that without treatment can become serious, and even cause the death of the patient.
