Answer:
The problem will be because:
- <u>The error in the construction of the bridge will be actually 40 cm</u>.
Explanation:
When you, as an engineer, listen about a scale 1/20, it means that for each 1 cm in the model, it will be 20 cm in the real footbridge (20 times upper to the scale model), then how the error in the model is 2 cm, the real error is 40 cm, in this case, imagine that you didn't know that the bridge will have an error of 40 cm, which is approximately 1,31 ft, <em><u>from a side of the bridge you begin with the correct measure, and the other side you use the measure with the error of the 40 cm, the result is that when you going to finish the bridge in the center, this won't match, making more expenses to correct that big error</u></em>.
The Best-Correct Statements as it Pertains to the Control Group and Experimental Group are:
- The Control Group Receives No Drug while The Experimental Group Receives No Drug 911-918.

What are the control and experimental group in a study?
The control group in a study is the group in which no changes are applied to the group.
In the control group, the variables are kept constant, hence, the control group is also known as the constant group.
The experimental group in a study is the group to which the treatment being studied is applied. The control group receives the treatment of the variable under study.
Hence, the group that receives the drug 911-918 is the experimental group.

Answer:
A) A tentative statement used to guide a scientific investigation is called scientific hypothesis.
As hypothesis is a proposed details of a phenomena, it can guide us in one way or another to carry out the scientific investigation.
B) Makes prediction about future events is scientific hypothesis.
Scientific hypothesis bases on the observation made predicts about future events, which could be either true or false.
C) Can be tested many independent researches is a scientific theory.
A scientific theory is developed when it has been passed through many researches and had gained acceptance too.
D) Both Scientific theory and hypothesis are based on the observations of the natural phenomena.
Firstly, an observation is made based on natural phenomena, which leads to questions, then research or study is carried out to answer these questions leading to the formation of a hypothesis which upon successful testing forms a theory.
E) Scientific theory is a well-established highly reliable explanation.
It a highly sustained explanation based on facts of nature, that are confirmed via a lot of experiments.
