Given:
The equation is
To find:
The slope intercept form of the given equation.
Solution:
The slope intercept form of a linear equation is
Where, m is slope and b is the y-intercept.
We have,
We need to isolate y. Add 10x on both sides.
Divide both sides by 20.
Therefore, the slope intercept form of the given equation is .
If the sample size is 1488 and confidence interval of 99% then the margin of error is 0.03088.
Given sample size of 1488, percentage of those polled own a home be 69% and confidence level be 99%.
We are required to find the approximate margin of error.
Margin of error is the difference between calculated values and real values.
n=1488
p=0.69
Margin of error=z*
Z score when confidence level is 99%=2.576.
Margin of error=2.576*
=2.576*
=2.576*
=2.576*
=2.576*0.01198
=0.03088
Hence if the sample size is 1488 and confidence interval of 99% then the margin of error is 0.03088.
