Answer:
27.4 yards
Explanation:
The diagonal of a rectangle, one of it's length and one of it's width will form a right angle triangle
Let
Width = x
Length = 2x
Diagonal = 80 yards
c^2 = a^2 + b^2
Where
c= diagonal
a= length
b= width
c^2 = a^2 + b^2
80^2 = (2x)^2 + (x)^2
80^2 = 2x * 2x + x^2
80^2 = 4x^2 + x^2
6,400= 5x^2
Divide both sides by 5
x^2= 6400 / 5
= 1280
x^2 = 1,280
Find the square root of both sides
√x^2 = √1,280
x= 35.8
How many yards, to the nearest tenth of a yard, does a person save by walking diagonally across the land instead of walking its length and its width?
Yards saved= (Length + width) - diagonal
= (2x+x) - 80
= {2(35.8) + 35.8} - 80
= (71.6 + 35.8) - 80
= 107.4 - 80
= 27.4
Yards saved = 27.4 yards
When an adolescent's newly sophisticated metacognitive capability causes him or her to become self-absorbed and believe that the world is focused on only him or her, this is called <u>b) adolescent egocentrism</u>.
<u>Explanation</u>:
Adolescent egocentrism is the term used by psychologist to describe the incapability of young people to differentiate between their perception of what people think about them and what others actually think in reality.
The adolescent egocentrism concept was expressed by the psychologist David Elkind. Adolescent egocentrism is found in children of age 10-14 years. They always think about what others will think about them. The young people consider themselves as center of attention and never focus on others views.

Answer:
All the answers are correct because research is multifaceted
Explanation:
While doing population studies, it is important to understand the population and they demographic, age, sex, location etc. This could have incredible effects on comparative studies.
It is also important to maintain an open line of communication to give instructions and follow up on the persons in the event that this kind of data is required. But like with population study the error that often comes into play is the element of human dishonesty. By keeping an open line of communication, the provisions can be made to keep this under check.
Finally, making sure that all the participants understand what is being asked of them is key to the open line of communication as not to create any misgivings or misunderstanding.
