The answer that you should get 35as^2-30s
Answer:
The provided study is an experiment.
Step-by-step explanation:
Consider the provided information.
Observational study: In this study observer only observe the subjects, and measure variables of interest without allocating treatments to subjects.
For example: you want to examine the side effect of smoke on lung.
Experiment study:The researchers are applying treatments to experimental units in the research, then the effect of the treatments on the experimental units is observed.
For example: Flipping a coin
Now consider the provided information:
Thirty university students are divided into two groups. One group receives free tutoring in mathematics comma the other doesn't. After one semester comma scores on final mathematical examinations are compared.
Here, the researcher applying treatment to experimental units.
Thus, the provided study is an experiment.
It is an isosceles triangle because it has two equal sides and a hypotenuse.
We have given that
A triangle has 2 sides that equal 5 inches. The other side equals 4 inches.
We have to determine the type of the triangle
<h3>Which triangle has two sides that are equal?</h3>
An isosceles triangle can be drawn in many different ways. It can be drawn to have two equal sides and two equal angles or with two acute angles and one obtuse angle.
Therefore,It is an isosceles triangle because it has two equal sides and a hypotenuse.
