Answer:
The degrees of freedom for this sample are 27.
The sample size to get a margin of error equal or less than 0.3656 is n=4450.
Step-by-step explanation:
The degrees of freedom for calculating the value of t are:

With 27 degrees of freedom and 95% confidence level, from a table we can get that the t-value is t=2.052.
The sample size to get a margin of error equal or less than 0.3656 can be calculated as:

Answer:3x+6=2x+21 base angle of isosceles triangle
3x-2x=21-6
X=15
<J=3×15+6=51
<k=2×15+21=51
,<I=180-51-51=78
Step-by-step explanation:
Y=1/4x-3
1/4x is rise over run or you go up or down then you go left or right. Since this is a positive line you will go up 1 and right 4. The -3 is the point in the y-axis that the line goes through
