The Atlanta Journal Constitution conducted a survey of 900 registered voters to determine which voting method they prefer. The A
photoshop1234 [79]

Answer:

a) (0.576, 0.624)

Step-by-step explanation:

Given that the sample proportion (p) = 60% = 0.6, sample size (n) = 900, confidence (C) = 85%

α = 1 - C = 1 - 0.85 = 0.15

α/2 = 0.075

The z score of α/2 (0.075) corresponds with the z score of 0.425 (0.5 - 0.075) which is equals to 1.44, hence z_\frac{\alpha }{2} =1.44

The margin of error (E) is:

E=z_\frac{\alpha }{2} *\sqrt{\frac{p(1-p)}{n} } =1.44*\sqrt{\frac{0.6(1-0.6)}{900} } = 0.024

The confidence interval = p ± E = 0.6 ± 0.024 = (0.576, 0.624)

The slope of the line below is to use the corners of the labeled point to find a point slope equation of the line.
dexar [7]

Answer: Choice A)  y - 10 = 2(x - 3)

============================================================

Explanation:

We can rule out choices C and D because this diagonal line has a positive slope (as it moves uphill when moving to the right).

So m = 2 must be the slope.

---------

Recall that

y - y1 = m(x - x1)

represents the point slope form of a linear equation.

The point shown on this graph is (3,10) meaning that x1 = 3 and y1 = 10 pair up together.

So,

y - y1 = m(x - x1)

y - 10 = 2(x - 3)

which points to <u>choice A</u> as the final answer

Prove that the line that passes through the points (5,1) and (6,3) is parallel to the line y=2x+3
exis [7]

Answer:

Find slope of other line

Step-by-step explanation:

1) so parallel lines have the same slope

If we find the slope of these two points we can prove those two lines are parallel!

3-1/6-5=2/1

The slope of this line=2

Slope of that line=2

Hence these two Lines are parallel hope this helps!
