The graph of a linear relationship has a slope of -5 and passes through the point (2, -12). Write the equation of the line in sl
1 answer:
<h3>Answer:</h3>
y=-5x-2
<h3>Solution:</h3>- We are given the line's slope and a point that it passes through.
- Using the given information, we can write the equation of the line in Point-Slope Form:
- In this formula, y₁ stands for the y-coordinate of the point, m stands for the slope of the line, and x₁ stands for the x-coordinate of the point.
- In this case, y₁ is equal to -12, m is equal to -5, and x₁ is equal to 2.
- Plug in the values:
- y-(-12)=-5(x-2)
- y+12=-5(x-2)
- Now, convert into Slope-Intercept Form, y=mx+b:
- y+12=-5x+10
- y=-5x+10-12
- y=-5x-2

Answer:
(A) The minimum sample size required achieve the margin of error of 0.04 is 601.
(B) The minimum sample size required achieve a margin of error of 0.02 is 2401.
Step-by-step explanation:
Let us assume that the percentage of support for the candidate, among voters in her district, is 50%.
(A)
The margin of error, <em>MOE</em> = 0.04.
The formula for margin of error is:
The critical value of <em>z</em> for 95% confidence interval is:
Compute the minimum sample size required as follows:
Thus, the minimum sample size required achieve the margin of error of 0.04 is 601.
(B)
The margin of error, <em>MOE</em> = 0.02.
The formula for margin of error is:
The critical value of <em>z</em> for 95% confidence interval is:
Compute the minimum sample size required as follows:
Thus, the minimum sample size required achieve a margin of error of 0.02 is 2401.
