Answer:d=a2+b2 ∣a(x0)+b(y0)+c∣. So given a line of the form a x + b y + c ax+by+c ax+by+c and a point ( x 0 , y 0 ) , (x_{0},y_{0}), (x0,y0), the perpendicular distance can be found by the above formula.
Step-by-step explanation:

Answer:
-5/8, -0.62, -0.615
Step-by-step explanation:
For -5/8, dividing -5 by 8 will result in -0.63, that's why it's the least (the farthest negative number from 0).
Next is -0.62
Since -0.615 isn't rounded up to the nearest hundredths, it is the greatest because it's closest to 0.
Answer:
465
Step-by-step explanation:
Margin of error = critical value × standard error
ME = CV × SE
Assuming 95% confidence, CV = z = 1.96.
Standard error is:
SE = σ / √n
SE = 3.3 / √n
Given margin of error of 0.3:
0.3 = 1.96 × 3.3 / √n
n = 465
