We also know that the vertex should be (-2, 1)
Therefore, option 2 is the solution
The scale in cm to cm is:
1 cm = 20 cm
Step-by-step explanation:
Scales are used to draw maps and blueprints of large objects on paper.
Given scale is:
5 centimeters = 1 meter
WE have to find the centimeter to centimeter scale. In order to do so, we have to convert the meters into centimeters
As there are 100 centimeters in a meter
So,
the scale will be:
5 cm = 100 cm
Simplifying:
The scale in cm to cm is:
1 cm = 20 cm

Answer:
<h2>
$5.03</h2>
Step-by-step explanation:
Given data
Sample Mean (M): $48.77
Sample Size (n): 20
Standard Deviation (σ) : $17.58
Confidence Level: 80%
we know that z*-Values for 80% Confidence Levels is 1.28
the expression for margin of error is given bellow\
MOE= z*σ/√n
We can now substitute into the expression and solve for the MOE as
MOE= 1.28*17.58/√20
MOE= 22.502/4.47
MOE= 22.502/4.47
MOE= 5.03
The margin of error for a 80 % confidence interval is $5.03
