Answer: Margin of Error for the given CI is 0.08
Step-by-step explanation:
Given the data in the question;
it is a symmetric class interval hence, sample proportion p = (0.50 + 0.66) / 2
p = 1.16 / 2
sample proportion p = 0.58
Margin of Error E will be;
E = 1/2 × length of Confidence interval
Margin of Error E = 1/2 × ( 0.66 - 0.5)
Margin of Error E = 1/2 × 0.16
Margin of Error E = 0.08
Therefore; Margin of Error for the given CI is 0.08
Answer:
1rst one is right i believe
Step-by-step explanation:
Its law of cosines just trust me.
The idea of this exercise is that you realize the properties of the squares.
The first part is a set of instrucctions that guide you to go round the square and mark every corner oo it. Then you can count the corners (also named vertices) and verifiy that they are four.
This tells you that a property of the squares is that they have four corners or vertices.
The second part tells you go round the square and mark every side. In this way you can count the sides. The you verify that they are four sides.
This tells you that a property of the squares is that they have four sides.
{x,y} = {8,2}
That is the correct answer
