find the equation of the straight line passing through the point (3, 3) which is perpendicular to the line y=-1/2x-4
maw [93]

Answer:

y = 2x - 3

Step-by-step explanation:

The negative recipricol is -1/(-1/2) = 2

Use point-slope equation:

y-y1 = m(x-x1)

x1 = 3, y1=3

y-3 = 2(x-3)

y-3 = 2x-6

<u>y = 2x-3</u>

To solve for the margin of error:

margin of error = critical value x standard error

To compute for the critical value:
1. compute alpha: α= 1 - (confidence level/100) = 1 - .99 = 0.01
2. Find the critical probability: p = 1 - α/2 = 1 - (0.01/2) = 0.995
3. Look for the z score at the z table, in this case it is 2.58. This is your critical value.

To compute for the standard error, the formula is:
standard error = standard deviation (σ) divided by √n = 1.6 / √420 = 0.0781

Now plug in the following in the formula:

margin of error: 2.58 * 0.0781  = 0.2014 or 0.20

The answer is letter C.
