A survey was given to a random sample of 350 residents of a town to determine whether they support a new plan to raise taxes in order to increase education
spending. Of those surveyed, 20% of the people said they were in favor of the plan. At
the 95% confidence level, what is the margin of error for this survey expressed as a
percentage to the nearest tenth?

if the eqn of the parabola is f(x) = (x-4)(x+2), we need to mult. this out to find the coordinates of the vertex.

then f(x) = x^2 + 2x - 4x - 8, and f(x) = x^2 - 2x - 8.

one way in which you can find the vertex is to calculate x = -b / (2a).   here, that comes to

        )

x = = 1.   f(1) = 1^2 - 2(1) - 8 = - 9.   vertex is at (1, -9).

        2(1) 

find another point on the curve:   let x=0, for which y=-8.   then (0, -8) is on the curve.   plot the vertex and this point and draw a smooth parabola thru both.

step-by-step explanation:

2/5+1/2=9/10

6/1-9/10=5.1

60.9774

step-by-step explanation:

because when you add 47.6 plus 7.32 equals 54.92

and when you add .0574 + 6= 6.0574

and when you add 54.92 and 6.0574 you get the answer of 60.9774.

plzz mark brainlest last one got deleted. cause i didn't explain it but i did but i understand what the mod meant

step-by-step explanation:

where is the question is there is a formula or is there not one
