Find n, x, p and q
n always represent the population surveyed;
So:
x represents the sample from the population
So:
p always represents the given proportion
Solving for q
Answer:
Step-by-step explanation:
Because the x and y have been reversed in this equation, shifting the parabola to the left will be outside of the exponent and shifting up and down will be inside with the exponent.
The equation becomes .
Where subtracting by 2 moves it two units to the left and adding by 3 moves it 3 units down.
