The answer is that the assumed margin of error is 5%.
Here is how we calculate this;

MariettaO [177]

 100 in decimal term would be 1.00


.85 is LESS than 1.00 causing it to be a part/ or portion of 100.

Write an equation of the line that passes through the points<br> (0, 3) and (-5, 0).
Setler [38]

Answer:

y-3=3/5x

Step-by-step explanation:

y-y1=m(x-x1)

Where m=slope and (x1, y1) is a point on the line.

m=(y2-y1)/(x2-x1)

m=(0-3)/(-5-0)

m=-3/-5

m=3/5

y-3=3/5(x-0)

y-3=3/5(x)

y-3=3/5x
